### [12.0.4](https://github.com/npm/cacache/compare/v12.0.3...v12.0.4) (2020-03-24)
### [12.0.3](https://github.com/npm/cacache/compare/v12.0.2...v12.0.3) (2019-08-19)
### Bug Fixes
* do not chown if not running as root ([2d80af9](https://github.com/npm/cacache/commit/2d80af9))
### [12.0.2](https://github.com/npm/cacache/compare/v12.0.1...v12.0.2) (2019-07-19)
### [12.0.1](https://github.com/npm/cacache/compare/v12.0.0...v12.0.1) (2019-07-19)
* **deps** Abstracted out `lib/util/infer-owner.js` to
[@npmcli/infer-owner](https://www.npmjs.com/package/@npmcli/infer-owner)
so that it could be more easily used in other parts of the npm CLI.
## [12.0.0](https://github.com/npm/cacache/compare/v11.3.3...v12.0.0) (2019-07-15)
### Features
* infer uid/gid instead of accepting as options ([ac84d14](https://github.com/npm/cacache/commit/ac84d14))
* **i18n:** add another error message ([676cb32](https://github.com/npm/cacache/commit/676cb32))
### BREAKING CHANGES
* the uid gid options are no longer respected or
necessary. As of this change, cacache will always match the cache
contents to the ownership of the cache directory (or its parent
directory), regardless of what the caller passes in.
Reasoning:
The number one reason to use a uid or gid option was to keep root-owned
files from causing problems in the cache. In npm's case, this meant
that CLI's ./lib/command.js had to work out the appropriate uid and gid,
then pass it to the libnpmcommand module, which had to in turn pass the
uid and gid to npm-registry-fetch, which then passed it to
make-fetch-happen, which passed it to cacache. (For package fetching,
pacote would be in that mix as well.)
Added to that, `cacache.rm()` will actually _write_ a file into the
cache index, but has no way to accept an option so that its call to
entry-index.js will write the index with the appropriate uid/gid.
Little ownership bugs were all over the place, and tricky to trace
through. (Why should make-fetch-happen even care about accepting or
passing uids and gids? It's an http library.)
This change allows us to keep the cache from having mixed ownership in
any situation.
Of course, this _does_ mean that if you have a root-owned but
user-writable folder (for example, `/tmp`), then the cache will try to
chown everything to root.
The solution is for the user to create a folder, make it user-owned, and
use that, rather than relying on cacache to create the root cache folder.
If we decide to restore the uid/gid opts, and use ownership inferrence
only when uid/gid are unset, then take care to also make rm take an
option object, and pass it through to entry-index.js.

### Bug Fixes
* **test:** fix content.write tests when running in docker ([d2e9b6a](https://github.com/npm/cacache/commit/d2e9b6a))
### Features
* **integrity:** subresource integrity support (#78) ([b1e731f](https://github.com/npm/cacache/commit/b1e731f))
### BREAKING CHANGES
* **integrity:** The entire API has been overhauled to use SRI hashes instead of digest/hashAlgorithm pairs. SRI hashes follow the Subresource Integrity standard and support strings and objects compatible with [`ssri`](https://npm.im/ssri).
* This change bumps the index version, which will invalidate all previous index entries. Content entries will remain intact, and existing caches will automatically reuse any content from before this breaking change.
* `cacache.get.info()`, `cacache.ls()`, and `cacache.ls.stream()` will now return objects that looks like this:
```
{
key: String,
integrity: '<algorithm>-<base64hash>',
path: ContentPath,
time: Date<ms>,
metadata: Any
}
```
* `opts.digest` and `opts.hashAlgorithm` are obsolete for any API calls that used them.
* Anywhere `opts.digest` was accepted, `opts.integrity` is now an option. Any valid SRI hash is accepted here -- multiple hash entries will be resolved according to the standard: first, the "strongest" hash algorithm will be picked, and then each of the entries for that algorithm will be matched against the content. Content will be validated if *any* of the entries match (so, a single integrity string can be used for multiple "versions" of the same document/data).
* `put.byDigest()`, `put.stream.byDigest`, `get.byDigest()` and `get.stream.byDigest()` now expect an SRI instead of a `digest` + `opts.hashAlgorithm` pairing.
* `get.hasContent()` now expects an integrity hash instead of a digest. If content exists, it will return the specific single integrity hash that was found in the cache.
* `verify()` has learned to handle integrity-based caches, and forgotten how to handle old-style cache indices due to the format change.
* `cacache.rm.content()` now expects an integrity hash instead of a hex digest.

* cache: index/content directories are now versioned. Previous caches are no longer compatible and cannot be migrated.
* util: fix-owner now uses Promises instead of callbacks
* index: Previously-generated index entries are no longer compatible and the index must be regenerated.
* index: The index format has changed and previous caches are no longer compatible. Existing caches will need to be regenerated.
* hashes: Default hashAlgorithm changed from sha1 to sha512. If you
rely on the prior setting, pass `opts.hashAlgorithm` in explicitly.
* content: Previously-generated content directories are no longer compatible
and must be regenerated.
* verify: API is now promise-based
* read: Switches to a Promise-based API and removes callback stuff
* rm: Switches to a Promise-based API and removes callback stuff
* index: this changes the API to work off promises instead of callbacks
* api: this means we are going all in on promises now

[`cacache`](https://github.com/zkat/cacache) es una librería de Node.js para
manejar caches locales en disco, con acceso tanto con claves únicas como
direcciones de contenido (hashes/hacheos). Es súper rápida, excelente con el
acceso concurrente, y jamás te dará datos incorrectos, aún si se corrompen o
manipulan directamente los ficheros del cache.
El propósito original era reemplazar el caché local de
[npm](https://npm.im/npm), pero se puede usar por su propia cuenta.
_Traducciones: [English](README.md)_

const fs = require('fs')
const tarbol = '/ruta/a/mi-tar.tgz'
const rutaCache = '/tmp/my-toy-cache'
const clave = 'mi-clave-única-1234'
// ¡Añádelo al caché! Usa `rutaCache` como raíz del caché.
cacache.mete(rutaCache, clave, '10293801983029384').then(integrity => {
console.log(`Saved content to ${rutaCache}.`)
})
const destino = '/tmp/mytar.tgz'
// Copia el contenido del caché a otro fichero, pero esta vez con flujos.
cacache.saca.flujo(
rutaCache, clave
).pipe(
fs.createWriteStream(destino)
).on('finish', () => {
console.log('extracción completada')
})
// La misma cosa, pero accesando el contenido directamente, sin tocar el índice.
cacache.saca.porHacheo(rutaCache, integridad).then(datos => {
fs.writeFile(destino, datos, err => {
console.log('datos del tarbol sacados basado en su sha512, y escrito a otro fichero')
})
})
```
### Características
* Extracción por clave o por dirección de contenido (shasum, etc)
* Usa el estándard de web, [Subresource Integrity](#integrity)
* Compatible con multiples algoritmos - usa sha1, sha512, etc, en el mismo caché sin problema
* Entradas con contenido idéntico comparten ficheros
* Tolerancia de fallas (inmune a corrupción, ficheros parciales, carreras de proceso, etc)
* Verificación completa de datos cuando (escribiendo y leyendo)
* Concurrencia rápida, segura y "lockless"
* Compatible con `stream`s (flujos)
* Compatible con `Promise`s (promesas)
* Bastante rápida -- acceso, incluyendo verificación, en microsegundos
* Almacenaje de metadatos arbitrarios
* Colección de basura y verificación adicional fuera de banda
* Cobertura rigurosa de pruebas
* Probablente hay un "Bloom filter" por ahí en algún lado. Eso le mola a la gente, ¿Verdad? 🤔

### API
#### <a name="localized-api"></a> Usando el API en español
cacache incluye una traducción completa de su API al castellano, con las mismas
características. Para usar el API como está documentado en este documento, usa
`require('cacache/es')`
cacache también tiene otros lenguajes: encuéntralos bajo `./locales`, y podrás
usar el API en ese lenguaje con `require('cacache/<lenguaje>')`
#### <a name="ls"></a> `> cacache.ls(cache) -> Promise<Object>`
Enumera todas las entradas en el caché, dentro de un solo objeto. Cada entrada
en el objeto tendrá como clave la clave única usada para el índice, el valor
siendo un objeto de [`saca.info`](#get-info).
##### Ejemplo
```javascript
cacache.ls(rutaCache).then(console.log)
// Salida
{
'my-thing': {
key: 'my-thing',
integrity: 'sha512-BaSe64/EnCoDED+HAsh=='
path: '.testcache/content/deadbeef', // unido con `rutaCache`
time: 12345698490,
size: 4023948,
metadata: {
name: 'blah',
version: '1.2.3',
description: 'this was once a package but now it is my-thing'
}
},
'other-thing': {
key: 'other-thing',
integrity: 'sha1-ANothER+hasH=',
path: '.testcache/content/bada55',
time: 11992309289,
size: 111112
}
}
```
#### <a name="ls-stream"></a> `> cacache.ls.flujo(cache) -> Readable`
Enumera todas las entradas en el caché, emitiendo un objeto de
[`saca.info`](#get-info) por cada evento de `data` en el flujo.
##### Ejemplo
```javascript
cacache.ls.flujo(rutaCache).on('data', console.log)
// Salida
{
key: 'my-thing',
integrity: 'sha512-BaSe64HaSh',
path: '.testcache/content/deadbeef', // unido con `rutaCache`
time: 12345698490,
size: 13423,
metadata: {
name: 'blah',
version: '1.2.3',
description: 'this was once a package but now it is my-thing'
}
}
{
key: 'other-thing',
integrity: 'whirlpool-WoWSoMuchSupport',
path: '.testcache/content/bada55',
time: 11992309289,
size: 498023984029
}
{
...
}
```
#### <a name="get-data"></a> `> cacache.saca(cache, clave, [ops]) -> Promise({data, metadata, integrity})`
Devuelve un objeto con los datos, hacheo de integridad y metadatos identificados
por la `clave`. La propiedad `data` de este objeto será una instancia de
`Buffer` con los datos almacenados en el caché. to do with it! cacache just
won't care.
`integrity` es un `string` de [Subresource Integrity](#integrity). Dígase, un
`string` que puede ser usado para verificar a la `data`, que tiene como formato
`<algoritmo>-<hacheo-integridad-base64>`.
So no existe ninguna entrada identificada por `clave`, o se los datos
almacenados localmente fallan verificación, el `Promise` fallará.
Una sub-función, `saca.porHacheo`, tiene casi el mismo comportamiento, excepto
que busca entradas usando el hacheo de integridad, sin tocar el índice general.
Esta versión *sólo* devuelve `data`, sin ningún objeto conteniéndola.
##### Nota
Esta función lee la entrada completa a la memoria antes de devolverla. Si estás
almacenando datos Muy Grandes, es posible que [`saca.flujo`](#get-stream) sea
una mejor solución.
##### Ejemplo
```javascript
// Busca por clave
cache.saca(rutaCache, 'my-thing').then(console.log)
// Salida:
{
metadata: {
thingName: 'my'
},
integrity: 'sha512-BaSe64HaSh',
data: Buffer#<deadbeef>,
size: 9320
}
// Busca por hacheo
cache.saca.porHacheo(rutaCache, 'sha512-BaSe64HaSh').then(console.log)
// Salida:
Buffer#<deadbeef>
```
#### <a name="get-stream"></a> `> cacache.saca.flujo(cache, clave, [ops]) -> Readable`
Devuelve un [Readable
Stream](https://nodejs.org/api/stream.html#stream_readable_streams) de los datos
almacenados bajo `clave`.
So no existe ninguna entrada identificada por `clave`, o se los datos
almacenados localmente fallan verificación, el `Promise` fallará.
`metadata` y `integrity` serán emitidos como eventos antes de que el flujo
cierre.
Una sub-función, `saca.flujo.porHacheo`, tiene casi el mismo comportamiento,
excepto que busca entradas usando el hacheo de integridad, sin tocar el índice
general. Esta versión no emite eventos de `metadata` o `integrity`.
##### Ejemplo
```javascript
// Busca por clave
cache.saca.flujo(
rutaCache, 'my-thing'
).on('metadata', metadata => {
console.log('metadata:', metadata)
}).on('integrity', integrity => {
console.log('integrity:', integrity)
}).pipe(
fs.createWriteStream('./x.tgz')
)
// Salidas:
metadata: { ... }
integrity: 'sha512-SoMeDIGest+64=='
// Busca por hacheo
cache.saca.flujo.porHacheo(
rutaCache, 'sha512-SoMeDIGest+64=='
).pipe(
fs.createWriteStream('./x.tgz')
)
```
#### <a name="get-info"></a> `> cacache.saca.info(cache, clave) -> Promise`
Busca la `clave` en el índice del caché, devolviendo información sobre la
entrada si existe.
##### Campos
* `key` - Clave de la entrada. Igual al argumento `clave`.
* `integrity` - [hacheo de Subresource Integrity](#integrity) del contenido al que se refiere esta entrada.
* `path` - Dirección del fichero de datos almacenados, unida al argumento `cache`.
* `time` - Hora de creación de la entrada
* `metadata` - Metadatos asignados a esta entrada por el usuario
##### Ejemplo
```javascript
cacache.saca.info(rutaCache, 'my-thing').then(console.log)
// Salida
{
key: 'my-thing',
integrity: 'sha256-MUSTVERIFY+ALL/THINGS=='
path: '.testcache/content/deadbeef',
time: 12345698490,
size: 849234,
metadata: {
name: 'blah',
version: '1.2.3',
description: 'this was once a package but now it is my-thing'
}
}
```
#### <a name="get-hasContent"></a> `> cacache.saca.tieneDatos(cache, integrity) -> Promise`
Busca un [hacheo Subresource Integrity](#integrity) en el caché. Si existe el
contenido asociado con `integrity`, devuelve un objeto con dos campos: el hacheo
_específico_ que se usó para la búsqueda, `sri`, y el tamaño total del
contenido, `size`. Si no existe ningún contenido asociado con `integrity`,
devuelve `false`.
##### Ejemplo
```javascript
cacache.saca.tieneDatos(rutaCache, 'sha256-MUSTVERIFY+ALL/THINGS==').then(console.log)
// Salida
{
sri: {
source: 'sha256-MUSTVERIFY+ALL/THINGS==',
algorithm: 'sha256',
digest: 'MUSTVERIFY+ALL/THINGS==',
options: []
},
size: 9001
}
cacache.saca.tieneDatos(rutaCache, 'sha521-NOT+IN/CACHE==').then(console.log)
// Salida
false
```
#### <a name="put-data"></a> `> cacache.mete(cache, clave, datos, [ops]) -> Promise`
Inserta `datos` en el caché. El `Promise` devuelto se resuelve con un hacheo
(generado conforme a [`ops.algorithms`](#optsalgorithms)) después que la entrada
haya sido escrita en completo.
##### Ejemplo
```javascript
fetch(
'https://registry.npmjs.org/cacache/-/cacache-1.0.0.tgz'
).then(datos => {
return cacache.mete(rutaCache, 'registry.npmjs.org|cacache@1.0.0', datos)
}).then(integridad => {
console.log('el hacheo de integridad es', integridad)
})
```
#### <a name="put-stream"></a> `> cacache.mete.flujo(cache, clave, [ops]) -> Writable`
Devuelve un [Writable
Stream](https://nodejs.org/api/stream.html#stream_writable_streams) que inserta
al caché los datos escritos a él. Emite un evento `integrity` con el hacheo del
contenido escrito, cuando completa.
##### Ejemplo
```javascript
request.get(
'https://registry.npmjs.org/cacache/-/cacache-1.0.0.tgz'
).pipe(
cacache.mete.flujo(
rutaCache, 'registry.npmjs.org|cacache@1.0.0'
).on('integrity', d => console.log(`integrity digest is ${d}`))
)
```
#### <a name="put-options"></a> `> opciones para cacache.mete`
La funciones `cacache.mete` tienen un número de opciones en común.
##### `ops.metadata`
Metadatos del usuario que se almacenarán con la entrada.
##### `ops.size`
El tamaño declarado de los datos que se van a insertar. Si es proveído, cacache
verificará que los datos escritos sean de ese tamaño, o si no, fallará con un
error con código `EBADSIZE`.
##### `ops.integrity`
El hacheo de integridad de los datos siendo escritos.
Si es proveído, y los datos escritos no le corresponden, la operación fallará
con un error con código `EINTEGRITY`.
`ops.algorithms` no tiene ningún efecto si esta opción está presente.
##### `ops.algorithms`
Por Defecto: `['sha512']`
Algoritmos que se deben usar cuando se calcule el hacheo de [subresource
integrity](#integrity) para los datos insertados. Puede usar cualquier algoritmo
enumerado en `crypto.getHashes()`.
Por el momento, sólo se acepta un algoritmo (dígase, un array con exáctamente un
valor). No tiene ningún efecto si `ops.integrity` también ha sido proveido.
##### `ops.uid`/`ops.gid`
Si están presentes, cacache hará todo lo posible para asegurarse que todos los
ficheros creados en el proceso de sus operaciones en el caché usen esta
combinación en particular.
##### `ops.memoize`
Por Defecto: `null`
Si es verdad, cacache tratará de memoizar los datos de la entrada en memoria. La
próxima vez que el proceso corriente trate de accesar los datos o entrada,
cacache buscará en memoria antes de buscar en disco.
Si `ops.memoize` es un objeto regular o un objeto como `Map` (es decir, un
objeto con métodos `get()` y `set()`), este objeto en sí sera usado en vez del
caché de memoria global. Esto permite tener lógica específica a tu aplicación
encuanto al almacenaje en memoria de tus datos.
Si quieres asegurarte que los datos se lean del disco en vez de memoria, usa
`memoize: false` cuando uses funciones de `cacache.saca`.
#### <a name="rm-all"></a> `> cacache.rm.todo(cache) -> Promise`
Borra el caché completo, incluyendo ficheros temporeros, ficheros de datos, y el
índice del caché.
##### Ejemplo
```javascript
cacache.rm.todo(rutaCache).then(() => {
console.log('THE APOCALYPSE IS UPON US 😱')
})
```
#### <a name="rm-entry"></a> `> cacache.rm.entrada(cache, clave) -> Promise`
Alias: `cacache.rm`
Borra la entrada `clave` del índuce. El contenido asociado con esta entrada
seguirá siendo accesible por hacheo usando
[`saca.flujo.porHacheo`](#get-stream).
Para borrar el contenido en sí, usa [`rm.datos`](#rm-content). Si quieres hacer
esto de manera más segura (pues ficheros de contenido pueden ser usados por
multiples entradas), usa [`verifica`](#verify) para borrar huérfanos.
##### Ejemplo
```javascript
cacache.rm.entrada(rutaCache, 'my-thing').then(() => {
console.log('I did not like it anyway')
})
```
#### <a name="rm-content"></a> `> cacache.rm.datos(cache, integrity) -> Promise`
Borra el contenido identificado por `integrity`. Cualquier entrada que se
refiera a este contenido quedarán huérfanas y se invalidarán si se tratan de
accesar, al menos que contenido idéntico sea añadido bajo `integrity`.
##### Ejemplo
```javascript
cacache.rm.datos(rutaCache, 'sha512-SoMeDIGest/IN+BaSE64==').then(() => {
console.log('los datos para `mi-cosa` se borraron')
})
```
#### <a name="set-locale"></a> `> cacache.ponLenguaje(locale)`
Configura el lenguaje usado para mensajes y errores de cacache. La lista de
lenguajes disponibles está en el directorio `./locales` del proyecto.
_Te interesa añadir más lenguajes? [Somete un PR](CONTRIBUTING.md)!_
#### <a name="clear-memoized"></a> `> cacache.limpiaMemoizado()`
Completamente reinicializa el caché de memoria interno. Si estás usando tu
propio objecto con `ops.memoize`, debes hacer esto de manera específica a él.
#### <a name="tmp-mkdir"></a> `> tmp.hazdir(cache, ops) -> Promise<Path>`
Alias: `tmp.mkdir`
Devuelve un directorio único dentro del directorio `tmp` del caché.
Una vez tengas el directorio, es responsabilidad tuya asegurarte que todos los
ficheros escrito a él sean creados usando los permisos y `uid`/`gid` concordante
con el caché. Si no, puedes pedirle a cacache que lo haga llamando a
[`cacache.tmp.fix()`](#tmp-fix). Esta función arreglará todos los permisos en el
directorio tmp.
Si quieres que cacache limpie el directorio automáticamente cuando termines, usa
[`cacache.tmp.conTmp()`](#with-tpm).
##### Ejemplo
```javascript
cacache.tmp.mkdir(cache).then(dir => {
fs.writeFile(path.join(dir, 'blablabla'), Buffer#<1234>, ...)
})
```
#### <a name="with-tmp"></a> `> tmp.conTmp(cache, ops, cb) -> Promise`
Crea un directorio temporero con [`tmp.mkdir()`](#tmp-mkdir) y ejecuta `cb` con
él como primer argumento. El directorio creado será removido automáticamente
cuando el valor devolvido por `cb()` se resuelva.
Las mismas advertencias aplican en cuanto a manejando permisos para los ficheros
dentro del directorio.
##### Ejemplo
```javascript
cacache.tmp.conTmp(cache, dir => {
return fs.writeFileAsync(path.join(dir, 'blablabla'), Buffer#<1234>, ...)
}).then(() => {
// `dir` no longer exists
})
```
#### <a name="integrity"></a> Hacheos de Subresource Integrity
cacache usa strings que siguen la especificación de [Subresource Integrity
spec](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity).
Es decir, donde quiera cacache espera un argumento o opción `integrity`, ese
string debería usar el formato `<algoritmo>-<hacheo-base64>`.
Una variación importante sobre los hacheos que cacache acepta es que acepta el
nombre de cualquier algoritmo aceptado por el proceso de Node.js donde se usa.
Puedes usar `crypto.getHashes()` para ver cuales están disponibles.
##### Generando tus propios hacheos
Si tienes un `shasum`, en general va a estar en formato de string hexadecimal
(es decir, un `sha1` se vería como algo así:
`5f5513f8822fdbe5145af33b64d8d970dcf95c6e`).
Para ser compatible con cacache, necesitas convertir esto a su equivalente en
subresource integrity. Por ejemplo, el hacheo correspondiente al ejemplo
anterior sería: `sha1-X1UT+IIv2+UUWvM7ZNjZcNz5XG4=`.
Puedes usar código así para generarlo por tu cuenta:
```javascript
const crypto = require('crypto')
const algoritmo = 'sha512'
const datos = 'foobarbaz'
const integrity = (
algorithm +
'-' +
crypto.createHash(algoritmo).update(datos).digest('base64')
)
```
También puedes usar [`ssri`](https://npm.im/ssri) para deferir el trabajo a otra
librería que garantiza que todo esté correcto, pues maneja probablemente todas
las operaciones que tendrías que hacer con SRIs, incluyendo convirtiendo entre
hexadecimal y el formato SRI.
#### <a name="verify"></a> `> cacache.verifica(cache, ops) -> Promise`
Examina y arregla tu caché:
* Limpia entradas inválidas, huérfanas y corrompidas
* Te deja filtrar cuales entradas retener, con tu propio filtro
* Reclama cualquier ficheros de contenido sin referencias en el índice
* Verifica integridad de todos los ficheros de contenido y remueve los malos
* Arregla permisos del caché
* Remieve el directorio `tmp` en el caché, y todo su contenido.
Cuando termine, devuelve un objeto con varias estadísticas sobre el proceso de
verificación, por ejemplo la cantidad de espacio de disco reclamado, el número
de entradas válidas, número de entradas removidas, etc.
##### Opciones
* `ops.uid` - uid para asignarle al caché y su contenido
* `ops.gid` - gid para asignarle al caché y su contenido
* `ops.filter` - recibe una entrada como argumento. Devuelve falso para removerla. Nota: es posible que esta función sea invocada con la misma entrada más de una vez.
##### Example
```sh
echo somegarbage >> $RUTACACHE/content/deadbeef
```
```javascript
cacache.verifica(rutaCache).then(stats => {
// deadbeef collected, because of invalid checksum.
console.log('cache is much nicer now! stats:', stats)

# cacache [![npm version](https://img.shields.io/npm/v/cacache.svg)](https://npm.im/cacache) [![license](https://img.shields.io/npm/l/cacache.svg)](https://npm.im/cacache) [![Travis](https://img.shields.io/travis/npm/cacache.svg)](https://travis-ci.org/npm/cacache) [![AppVeyor](https://ci.appveyor.com/api/projects/status/github/npm/cacache?svg=true)](https://ci.appveyor.com/project/npm/cacache) [![Coverage Status](https://coveralls.io/repos/github/npm/cacache/badge.svg?branch=latest)](https://coveralls.io/github/npm/cacache?branch=latest)
[`cacache`](https://github.com/npm/cacache) is a Node.js library for managing
local key and content address caches. It's really fast, really good at
concurrency, and it will never give you corrupted data, even if cache files
get corrupted or manipulated.
On systems that support user and group settings on files, cacache will
match the `uid` and `gid` values to the folder where the cache lives, even
when running as `root`.
It was written to be used as [npm](https://npm.im)'s local cache, but can
just as easily be used on its own.
_Translations: [español](README.es.md)_

### Example
```javascript
const cacache = require('cacache/en')
const fs = require('fs')
const tarball = '/path/to/mytar.tgz'
const cachePath = '/tmp/my-toy-cache'
const key = 'my-unique-key-1234'
// Cache it! Use `cachePath` as the root of the content cache
cacache.put(cachePath, key, '10293801983029384').then(integrity => {
console.log(`Saved content to ${cachePath}.`)
})
const destination = '/tmp/mytar.tgz'
// Copy the contents out of the cache and into their destination!
// But this time, use stream instead!
cacache.get.stream(
cachePath, key
).pipe(
fs.createWriteStream(destination)
).on('finish', () => {
console.log('done extracting!')
})
// The same thing, but skip the key index.
cacache.get.byDigest(cachePath, integrityHash).then(data => {
fs.writeFile(destination, data, err => {
console.log('tarball data fetched based on its sha512sum and written out!')
})
})
```
### Features
* Extraction by key or by content address (shasum, etc)
* [Subresource Integrity](#integrity) web standard support
* Multi-hash support - safely host sha1, sha512, etc, in a single cache
* Automatic content deduplication
* Fault tolerance (immune to corruption, partial writes, process races, etc)
* Consistency guarantees on read and write (full data verification)
* Lockless, high-concurrency cache access
* Streaming support
* Promise support
* Pretty darn fast -- sub-millisecond reads and writes including verification
* Arbitrary metadata storage
* Garbage collection and additional offline verification
* Thorough test coverage
* There's probably a bloom filter in there somewhere. Those are cool, right? 🤔

### API
#### <a name="localized-api"></a> Using localized APIs
cacache includes a complete API in English, with the same features as other
translations. To use the English API as documented in this README, use
`require('cacache/en')`. This is also currently the default if you do
`require('cacache')`, but may change in the future.
cacache also supports other languages! You can find the list of currently
supported ones by looking in `./locales` in the source directory. You can use
the API in that language with `require('cacache/<lang>')`.
Want to add support for a new language? Please go ahead! You should be able to
copy `./locales/en.js` and `./locales/en.json` and fill them in. Translating the
`README.md` is a bit more work, but also appreciated if you get around to it. 👍🏼
#### <a name="ls"></a> `> cacache.ls(cache) -> Promise<Object>`
Lists info for all entries currently in the cache as a single large object. Each
entry in the object will be keyed by the unique index key, with corresponding
[`get.info`](#get-info) objects as the values.
##### Example
```javascript
cacache.ls(cachePath).then(console.log)
// Output
{
'my-thing': {
key: 'my-thing',
integrity: 'sha512-BaSe64/EnCoDED+HAsh=='
path: '.testcache/content/deadbeef', // joined with `cachePath`
time: 12345698490,
size: 4023948,
metadata: {
name: 'blah',
version: '1.2.3',
description: 'this was once a package but now it is my-thing'
}
},
'other-thing': {
key: 'other-thing',
integrity: 'sha1-ANothER+hasH=',
path: '.testcache/content/bada55',
time: 11992309289,
size: 111112
}
}
```
#### <a name="ls-stream"></a> `> cacache.ls.stream(cache) -> Readable`
Lists info for all entries currently in the cache as a single large object.
This works just like [`ls`](#ls), except [`get.info`](#get-info) entries are
returned as `'data'` events on the returned stream.
##### Example
```javascript
cacache.ls.stream(cachePath).on('data', console.log)
// Output
{
key: 'my-thing',
integrity: 'sha512-BaSe64HaSh',
path: '.testcache/content/deadbeef', // joined with `cachePath`
time: 12345698490,
size: 13423,
metadata: {
name: 'blah',
version: '1.2.3',
description: 'this was once a package but now it is my-thing'
}
}
{
key: 'other-thing',
integrity: 'whirlpool-WoWSoMuchSupport',
path: '.testcache/content/bada55',
time: 11992309289,
size: 498023984029
}
{
...
}
```
#### <a name="get-data"></a> `> cacache.get(cache, key, [opts]) -> Promise({data, metadata, integrity})`
Returns an object with the cached data, digest, and metadata identified by
`key`. The `data` property of this object will be a `Buffer` instance that
presumably holds some data that means something to you. I'm sure you know what
to do with it! cacache just won't care.
`integrity` is a [Subresource
Integrity](#integrity)
string. That is, a string that can be used to verify `data`, which looks like
`<hash-algorithm>-<base64-integrity-hash>`.
If there is no content identified by `key`, or if the locally-stored data does
not pass the validity checksum, the promise will be rejected.
A sub-function, `get.byDigest` may be used for identical behavior, except lookup
will happen by integrity hash, bypassing the index entirely. This version of the
function *only* returns `data` itself, without any wrapper.
##### Note
This function loads the entire cache entry into memory before returning it. If
you're dealing with Very Large data, consider using [`get.stream`](#get-stream)
instead.
##### Example
```javascript
// Look up by key
cache.get(cachePath, 'my-thing').then(console.log)
// Output:
{
metadata: {
thingName: 'my'
},
integrity: 'sha512-BaSe64HaSh',
data: Buffer#<deadbeef>,
size: 9320
}
// Look up by digest
cache.get.byDigest(cachePath, 'sha512-BaSe64HaSh').then(console.log)
// Output:
Buffer#<deadbeef>
```
#### <a name="get-stream"></a> `> cacache.get.stream(cache, key, [opts]) -> Readable`
Returns a [Readable Stream](https://nodejs.org/api/stream.html#stream_readable_streams) of the cached data identified by `key`.
If there is no content identified by `key`, or if the locally-stored data does
not pass the validity checksum, an error will be emitted.
`metadata` and `integrity` events will be emitted before the stream closes, if
you need to collect that extra data about the cached entry.
A sub-function, `get.stream.byDigest` may be used for identical behavior,
except lookup will happen by integrity hash, bypassing the index entirely. This
version does not emit the `metadata` and `integrity` events at all.
##### Example
```javascript
// Look up by key
cache.get.stream(
cachePath, 'my-thing'
).on('metadata', metadata => {
console.log('metadata:', metadata)
}).on('integrity', integrity => {
console.log('integrity:', integrity)
}).pipe(
fs.createWriteStream('./x.tgz')
)
// Outputs:
metadata: { ... }
integrity: 'sha512-SoMeDIGest+64=='
// Look up by digest
cache.get.stream.byDigest(
cachePath, 'sha512-SoMeDIGest+64=='
).pipe(
fs.createWriteStream('./x.tgz')
)
```
#### <a name="get-info"></a> `> cacache.get.info(cache, key) -> Promise`
Looks up `key` in the cache index, returning information about the entry if
one exists.
##### Fields
* `key` - Key the entry was looked up under. Matches the `key` argument.
* `integrity` - [Subresource Integrity hash](#integrity) for the content this entry refers to.
* `path` - Filesystem path where content is stored, joined with `cache` argument.
* `time` - Timestamp the entry was first added on.
* `metadata` - User-assigned metadata associated with the entry/content.
##### Example
```javascript
cacache.get.info(cachePath, 'my-thing').then(console.log)
// Output
{
key: 'my-thing',
integrity: 'sha256-MUSTVERIFY+ALL/THINGS=='
path: '.testcache/content/deadbeef',
time: 12345698490,
size: 849234,
metadata: {
name: 'blah',
version: '1.2.3',
description: 'this was once a package but now it is my-thing'
}
}
```
#### <a name="get-hasContent"></a> `> cacache.get.hasContent(cache, integrity) -> Promise`
Looks up a [Subresource Integrity hash](#integrity) in the cache. If content
exists for this `integrity`, it will return an object, with the specific single integrity hash
that was found in `sri` key, and the size of the found content as `size`. If no content exists for this integrity, it will return `false`.
##### Example
```javascript
cacache.get.hasContent(cachePath, 'sha256-MUSTVERIFY+ALL/THINGS==').then(console.log)
// Output
{
sri: {
source: 'sha256-MUSTVERIFY+ALL/THINGS==',
algorithm: 'sha256',
digest: 'MUSTVERIFY+ALL/THINGS==',
options: []
},
size: 9001
}
cacache.get.hasContent(cachePath, 'sha521-NOT+IN/CACHE==').then(console.log)
// Output
false
```
#### <a name="put-data"></a> `> cacache.put(cache, key, data, [opts]) -> Promise`
Inserts data passed to it into the cache. The returned Promise resolves with a
digest (generated according to [`opts.algorithms`](#optsalgorithms)) after the
cache entry has been successfully written.
##### Example
```javascript
fetch(
'https://registry.npmjs.org/cacache/-/cacache-1.0.0.tgz'
).then(data => {
return cacache.put(cachePath, 'registry.npmjs.org|cacache@1.0.0', data)
}).then(integrity => {
console.log('integrity hash is', integrity)
})
```
#### <a name="put-stream"></a> `> cacache.put.stream(cache, key, [opts]) -> Writable`
Returns a [Writable
Stream](https://nodejs.org/api/stream.html#stream_writable_streams) that inserts
data written to it into the cache. Emits an `integrity` event with the digest of
written contents when it succeeds.
##### Example
```javascript
request.get(
'https://registry.npmjs.org/cacache/-/cacache-1.0.0.tgz'
).pipe(
cacache.put.stream(
cachePath, 'registry.npmjs.org|cacache@1.0.0'
).on('integrity', d => console.log(`integrity digest is ${d}`))
)
```
#### <a name="put-options"></a> `> cacache.put options`
`cacache.put` functions have a number of options in common.
##### `opts.metadata`
Arbitrary metadata to be attached to the inserted key.
##### `opts.size`
If provided, the data stream will be verified to check that enough data was
passed through. If there's more or less data than expected, insertion will fail
with an `EBADSIZE` error.
##### `opts.integrity`
If present, the pre-calculated digest for the inserted content. If this option
if provided and does not match the post-insertion digest, insertion will fail
with an `EINTEGRITY` error.
`algorithms` has no effect if this option is present.
##### `opts.algorithms`
Default: ['sha512']
Hashing algorithms to use when calculating the [subresource integrity
digest](#integrity)
for inserted data. Can use any algorithm listed in `crypto.getHashes()` or
`'omakase'`/`'お任せします'` to pick a random hash algorithm on each insertion. You
may also use any anagram of `'modnar'` to use this feature.
Currently only supports one algorithm at a time (i.e., an array length of
exactly `1`). Has no effect if `opts.integrity` is present.
##### `opts.memoize`
Default: null
If provided, cacache will memoize the given cache insertion in memory, bypassing
any filesystem checks for that key or digest in future cache fetches. Nothing
will be written to the in-memory cache unless this option is explicitly truthy.
If `opts.memoize` is an object or a `Map`-like (that is, an object with `get`
and `set` methods), it will be written to instead of the global memoization
cache.
Reading from disk data can be forced by explicitly passing `memoize: false` to
the reader functions, but their default will be to read from memory.
#### <a name="rm-all"></a> `> cacache.rm.all(cache) -> Promise`
Clears the entire cache. Mainly by blowing away the cache directory itself.
##### Example
```javascript
cacache.rm.all(cachePath).then(() => {
console.log('THE APOCALYPSE IS UPON US 😱')
})
```
#### <a name="rm-entry"></a> `> cacache.rm.entry(cache, key) -> Promise`
Alias: `cacache.rm`
Removes the index entry for `key`. Content will still be accessible if
requested directly by content address ([`get.stream.byDigest`](#get-stream)).
To remove the content itself (which might still be used by other entries), use
[`rm.content`](#rm-content). Or, to safely vacuum any unused content, use
[`verify`](#verify).
##### Example
```javascript
cacache.rm.entry(cachePath, 'my-thing').then(() => {
console.log('I did not like it anyway')
})
```
#### <a name="rm-content"></a> `> cacache.rm.content(cache, integrity) -> Promise`
Removes the content identified by `integrity`. Any index entries referring to it
will not be usable again until the content is re-added to the cache with an
identical digest.
##### Example
```javascript
cacache.rm.content(cachePath, 'sha512-SoMeDIGest/IN+BaSE64==').then(() => {
console.log('data for my-thing is gone!')
})
```
#### <a name="set-locale"></a> `> cacache.setLocale(locale)`
Configure the language/locale used for messages and errors coming from cacache.
The list of available locales is in the `./locales` directory in the project
root.

#### <a name="clear-memoized"></a> `> cacache.clearMemoized()`
Completely resets the in-memory entry cache.
#### <a name="tmp-mkdir"></a> `> tmp.mkdir(cache, opts) -> Promise<Path>`
Returns a unique temporary directory inside the cache's `tmp` dir. This
directory will use the same safe user assignment that all the other stuff use.
Once the directory is made, it's the user's responsibility that all files
within are given the appropriate `gid`/`uid` ownership settings to match
the rest of the cache. If not, you can ask cacache to do it for you by
calling [`tmp.fix()`](#tmp-fix), which will fix all tmp directory
permissions.
If you want automatic cleanup of this directory, use
[`tmp.withTmp()`](#with-tpm)
##### Example
```javascript
cacache.tmp.mkdir(cache).then(dir => {
fs.writeFile(path.join(dir, 'blablabla'), Buffer#<1234>, ...)
})
```
#### <a name="tmp-fix"></a> `> tmp.fix(cache) -> Promise`
Sets the `uid` and `gid` properties on all files and folders within the tmp
folder to match the rest of the cache.
Use this after manually writing files into [`tmp.mkdir`](#tmp-mkdir) or
[`tmp.withTmp`](#with-tmp).
##### Example
```javascript
cacache.tmp.mkdir(cache).then(dir => {
writeFile(path.join(dir, 'file'), someData).then(() => {
// make sure we didn't just put a root-owned file in the cache
cacache.tmp.fix().then(() => {
// all uids and gids match now
})
})
})
```
#### <a name="with-tmp"></a> `> tmp.withTmp(cache, opts, cb) -> Promise`
Creates a temporary directory with [`tmp.mkdir()`](#tmp-mkdir) and calls `cb`
with it. The created temporary directory will be removed when the return value
of `cb()` resolves -- that is, if you return a Promise from `cb()`, the tmp
directory will be automatically deleted once that promise completes.
The same caveats apply when it comes to managing permissions for the tmp dir's
contents.
##### Example
```javascript
cacache.tmp.withTmp(cache, dir => {
return fs.writeFileAsync(path.join(dir, 'blablabla'), Buffer#<1234>, ...)
}).then(() => {
// `dir` no longer exists
})
```
#### <a name="integrity"></a> Subresource Integrity Digests
For content verification and addressing, cacache uses strings following the
[Subresource
Integrity spec](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity).
That is, any time cacache expects an `integrity` argument or option, it
should be in the format `<hashAlgorithm>-<base64-hash>`.
One deviation from the current spec is that cacache will support any hash
algorithms supported by the underlying Node.js process. You can use
`crypto.getHashes()` to see which ones you can use.
##### Generating Digests Yourself
If you have an existing content shasum, they are generally formatted as a
hexadecimal string (that is, a sha1 would look like:
`5f5513f8822fdbe5145af33b64d8d970dcf95c6e`). In order to be compatible with
cacache, you'll need to convert this to an equivalent subresource integrity
string. For this example, the corresponding hash would be:
`sha1-X1UT+IIv2+UUWvM7ZNjZcNz5XG4=`.
If you want to generate an integrity string yourself for existing data, you can
use something like this:
```javascript
const crypto = require('crypto')
const hashAlgorithm = 'sha512'
const data = 'foobarbaz'
const integrity = (
hashAlgorithm +
'-' +
crypto.createHash(hashAlgorithm).update(data).digest('base64')
)
```
You can also use [`ssri`](https://npm.im/ssri) to have a richer set of functionality
around SRI strings, including generation, parsing, and translating from existing
hex-formatted strings.
#### <a name="verify"></a> `> cacache.verify(cache, opts) -> Promise`
Checks out and fixes up your cache:
* Cleans up corrupted or invalid index entries.
* Custom entry filtering options.
* Garbage collects any content entries not referenced by the index.
* Checks integrity for all content entries and removes invalid content.
* Fixes cache ownership.
* Removes the `tmp` directory in the cache and all its contents.
When it's done, it'll return an object with various stats about the verification
process, including amount of storage reclaimed, number of valid entries, number
of entries removed, etc.
##### Options
* `opts.filter` - receives a formatted entry. Return false to remove it.
Note: might be called more than once on the same entry.
##### Example
```sh
echo somegarbage >> $CACHEPATH/content/deadbeef
```
```javascript
cacache.verify(cachePath).then(stats => {
// deadbeef collected, because of invalid checksum.
console.log('cache is much nicer now! stats:', stats)
})
```
#### <a name="verify-last-run"></a> `> cacache.verify.lastRun(cache) -> Promise`
Returns a `Date` representing the last time `cacache.verify` was run on `cache`.
##### Example
```javascript
cacache.verify(cachePath).then(() => {
cacache.verify.lastRun(cachePath).then(lastTime => {
console.log('cacache.verify was last called on' + lastTime)
})
})
```

# Introduction
Bluebird is a fully featured promise library with focus on innovative features and performance
See the [**bluebird website**](http://bluebirdjs.com/docs/getting-started.html) for further documentation, references and instructions. See the [**API reference**](http://bluebirdjs.com/docs/api-reference.html) here.
For bluebird 2.x documentation and files, see the [2.x tree](https://github.com/petkaantonov/bluebird/tree/2.x).
### Note
Promises in Node.js 10 are significantly faster than before. Bluebird still includes a lot of features like cancellation, iteration methods and warnings that native promises don't. If you are using Bluebird for performance rather than for those - please consider giving native promises a shot and running the benchmarks yourself.
# Questions and issues
The [github issue tracker](https://github.com/petkaantonov/bluebird/issues) is **_only_** for bug reports and feature requests. Anything else, such as questions for help in using the library, should be posted in [StackOverflow](http://stackoverflow.com/questions/tagged/bluebird) under tags `promise` and `bluebird`.
## Thanks
Thanks to BrowserStack for providing us with a free account which lets us support old browsers like IE8.

# lru cache
A cache object that deletes the least-recently-used items.
[![Build Status](https://travis-ci.org/isaacs/node-lru-cache.svg?branch=master)](https://travis-ci.org/isaacs/node-lru-cache) [![Coverage Status](https://coveralls.io/repos/isaacs/node-lru-cache/badge.svg?service=github)](https://coveralls.io/github/isaacs/node-lru-cache)
## Installation:
```javascript
npm install lru-cache --save
```
## Usage:
```javascript
var LRU = require("lru-cache")
, options = { max: 500
, length: function (n, key) { return n * 2 + key.length }
, dispose: function (key, n) { n.close() }
, maxAge: 1000 * 60 * 60 }
, cache = new LRU(options)
, otherCache = new LRU(50) // sets just the max size
cache.set("key", "value")
cache.get("key") // "value"
// non-string keys ARE fully supported
// but note that it must be THE SAME object, not
// just a JSON-equivalent object.
var someObject = { a: 1 }
cache.set(someObject, 'a value')
// Object keys are not toString()-ed
cache.set('[object Object]', 'a different value')
assert.equal(cache.get(someObject), 'a value')
// A similar object with same keys/values won't work,
// because it's a different object identity
assert.equal(cache.get({ a: 1 }), undefined)
cache.reset() // empty the cache
```
If you put more stuff in it, then items will fall out.
If you try to put an oversized thing in it, then it'll fall out right
away.
## Options
* `max` The maximum size of the cache, checked by applying the length
function to all values in the cache. Not setting this is kind of
silly, since that's the whole purpose of this lib, but it defaults
to `Infinity`. Setting it to a non-number or negative number will
throw a `TypeError`. Setting it to 0 makes it be `Infinity`.
* `maxAge` Maximum age in ms. Items are not pro-actively pruned out
as they age, but if you try to get an item that is too old, it'll
drop it and return undefined instead of giving it to you.
Setting this to a negative value will make everything seem old!
Setting it to a non-number will throw a `TypeError`.
* `length` Function that is used to calculate the length of stored
items. If you're storing strings or buffers, then you probably want
to do something like `function(n, key){return n.length}`. The default is
`function(){return 1}`, which is fine if you want to store `max`
like-sized things. The item is passed as the first argument, and
the key is passed as the second argumnet.
* `dispose` Function that is called on items when they are dropped
from the cache. This can be handy if you want to close file
descriptors or do other cleanup tasks when items are no longer
accessible. Called with `key, value`. It's called *before*
actually removing the item from the internal cache, so if you want
to immediately put it back in, you'll have to do that in a
`nextTick` or `setTimeout` callback or it won't do anything.
* `stale` By default, if you set a `maxAge`, it'll only actually pull
stale items out of the cache when you `get(key)`. (That is, it's
not pre-emptively doing a `setTimeout` or anything.) If you set
`stale:true`, it'll return the stale value before deleting it. If
you don't set this, then it'll return `undefined` when you try to
get a stale entry, as if it had already been deleted.
* `noDisposeOnSet` By default, if you set a `dispose()` method, then
it'll be called whenever a `set()` operation overwrites an existing
key. If you set this option, `dispose()` will only be called when a
key falls out of the cache, not when it is overwritten.
* `updateAgeOnGet` When using time-expiring entries with `maxAge`,
setting this to `true` will make each item's effective time update
to the current time whenever it is retrieved from cache, causing it
to not expire. (It can still fall out of cache based on recency of
use, of course.)
## API
* `set(key, value, maxAge)`
* `get(key) => value`
Both of these will update the "recently used"-ness of the key.
They do what you think. `maxAge` is optional and overrides the
cache `maxAge` option if provided.
If the key is not found, `get()` will return `undefined`.
The key and val can be any value.
* `peek(key)`
Returns the key value (or `undefined` if not found) without
updating the "recently used"-ness of the key.
(If you find yourself using this a lot, you *might* be using the
wrong sort of data structure, but there are some use cases where
it's handy.)
* `del(key)`
Deletes a key out of the cache.
* `reset()`
Clear the cache entirely, throwing away all values.
* `has(key)`
Check if a key is in the cache, without updating the recent-ness
or deleting it for being stale.
* `forEach(function(value,key,cache), [thisp])`
Just like `Array.prototype.forEach`. Iterates over all the keys
in the cache, in order of recent-ness. (Ie, more recently used
items are iterated over first.)
* `rforEach(function(value,key,cache), [thisp])`
The same as `cache.forEach(...)` but items are iterated over in
reverse order. (ie, less recently used items are iterated over
first.)
* `keys()`
Return an array of the keys in the cache.
* `values()`
Return an array of the values in the cache.
* `length`
Return total length of objects in cache taking into account
`length` options function.
* `itemCount`
Return total quantity of objects currently in cache. Note, that
`stale` (see options) items are returned as part of this item
count.
* `dump()`
Return an array of the cache entries ready for serialization and usage
with 'destinationCache.load(arr)`.
* `load(cacheEntriesArray)`
Loads another cache entries array, obtained with `sourceCache.dump()`,
into the cache. The destination cache is reset before loading new entries
* `prune()`
Manually iterates over the entire cache proactively pruning old entries

### API
#### <a name="parse"></a> `> ssri.parse(sri, [opts]) -> Integrity`
Parses `sri` into an `Integrity` data structure. `sri` can be an integrity
string, an `Hash`-like with `digest` and `algorithm` fields and an optional
`options` field, or an `Integrity`-like object. The resulting object will be an
`Integrity` instance that has this shape:
```javascript
{
'sha1': [{algorithm: 'sha1', digest: 'deadbeef', options: []}],
'sha512': [
{algorithm: 'sha512', digest: 'c0ffee', options: []},
{algorithm: 'sha512', digest: 'bad1dea', options: ['foo']}
],
}
```
If `opts.single` is truthy, a single `Hash` object will be returned. That is, a
single object that looks like `{algorithm, digest, options}`, as opposed to a
larger object with multiple of these.
If `opts.strict` is truthy, the resulting object will be filtered such that
it strictly follows the Subresource Integrity spec, throwing away any entries
with any invalid components. This also means a restricted set of algorithms
will be used -- the spec limits them to `sha256`, `sha384`, and `sha512`.
Strict mode is recommended if the integrity strings are intended for use in
browsers, or in other situations where strict adherence to the spec is needed.
##### Example
```javascript
ssri.parse('sha512-9KhgCRIx/AmzC8xqYJTZRrnO8OW2Pxyl2DIMZSBOr0oDvtEFyht3xpp71j/r/pAe1DM+JI/A+line3jUBgzQ7A==?foo') // -> Integrity object
```
#### <a name="stringify"></a> `> ssri.stringify(sri, [opts]) -> String`
This function is identical to [`Integrity#toString()`](#integrity-to-string),
except it can be used on _any_ object that [`parse`](#parse) can handle -- that
is, a string, an `Hash`-like, or an `Integrity`-like.
The `opts.sep` option defines the string to use when joining multiple entries
together. To be spec-compliant, this _must_ be whitespace. The default is a
single space (`' '`).
If `opts.strict` is true, the integrity string will be created using strict
parsing rules. See [`ssri.parse`](#parse).
##### Example
```javascript
// Useful for cleaning up input SRI strings:
ssri.stringify('\n\rsha512-foo\n\t\tsha384-bar')
// -> 'sha512-foo sha384-bar'
// Hash-like: only a single entry.
ssri.stringify({
algorithm: 'sha512',
digest:'9KhgCRIx/AmzC8xqYJTZRrnO8OW2Pxyl2DIMZSBOr0oDvtEFyht3xpp71j/r/pAe1DM+JI/A+line3jUBgzQ7A==',
options: ['foo']
})
// ->
// 'sha512-9KhgCRIx/AmzC8xqYJTZRrnO8OW2Pxyl2DIMZSBOr0oDvtEFyht3xpp71j/r/pAe1DM+JI/A+line3jUBgzQ7A==?foo'
// Integrity-like: full multi-entry syntax. Similar to output of `ssri.parse`
ssri.stringify({
'sha512': [
{
algorithm: 'sha512',
digest:'9KhgCRIx/AmzC8xqYJTZRrnO8OW2Pxyl2DIMZSBOr0oDvtEFyht3xpp71j/r/pAe1DM+JI/A+line3jUBgzQ7A==',
options: ['foo']
}
]
})
// ->
// 'sha512-9KhgCRIx/AmzC8xqYJTZRrnO8OW2Pxyl2DIMZSBOr0oDvtEFyht3xpp71j/r/pAe1DM+JI/A+line3jUBgzQ7A==?foo'
```
#### <a name="integrity-concat"></a> `> Integrity#concat(otherIntegrity, [opts]) -> Integrity`
Concatenates an `Integrity` object with another IntegrityLike, or an integrity
string.
This is functionally equivalent to concatenating the string format of both
integrity arguments, and calling [`ssri.parse`](#ssri-parse) on the new string.
If `opts.strict` is true, the new `Integrity` will be created using strict
parsing rules. See [`ssri.parse`](#parse).
##### Example
```javascript
// This will combine the integrity checks for two different versions of
// your index.js file so you can use a single integrity string and serve
// either of these to clients, from a single `<script>` tag.
const desktopIntegrity = ssri.fromData(fs.readFileSync('./index.desktop.js'))
const mobileIntegrity = ssri.fromData(fs.readFileSync('./index.mobile.js'))
// Note that browsers (and ssri) will succeed as long as ONE of the entries
// for the *prioritized* algorithm succeeds. That is, in order for this fallback
// to work, both desktop and mobile *must* use the same `algorithm` values.
desktopIntegrity.concat(mobileIntegrity)
```
#### <a name="integrity-to-string"></a> `> Integrity#toString([opts]) -> String`
Returns the string representation of an `Integrity` object. All hash entries
will be concatenated in the string by `opts.sep`, which defaults to `' '`.
If you want to serialize an object that didn't come from an `ssri` function,
use [`ssri.stringify()`](#stringify).
If `opts.strict` is true, the integrity string will be created using strict
parsing rules. See [`ssri.parse`](#parse).
##### Example
```javascript
const integrity = 'sha512-9KhgCRIx/AmzC8xqYJTZRrnO8OW2Pxyl2DIMZSBOr0oDvtEFyht3xpp71j/r/pAe1DM+JI/A+line3jUBgzQ7A==?foo'
ssri.parse(integrity).toString() === integrity
```
#### <a name="integrity-to-json"></a> `> Integrity#toJSON() -> String`
Returns the string representation of an `Integrity` object. All hash entries
will be concatenated in the string by `' '`.
This is a convenience method so you can pass an `Integrity` object directly to `JSON.stringify`.
For more info check out [toJSON() behavior on mdn](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#toJSON%28%29_behavior).
##### Example
```javascript
const integrity = '"sha512-9KhgCRIx/AmzC8xqYJTZRrnO8OW2Pxyl2DIMZSBOr0oDvtEFyht3xpp71j/r/pAe1DM+JI/A+line3jUBgzQ7A==?foo"'
JSON.stringify(ssri.parse(integrity)) === integrity
```
#### <a name="integrity-match"></a> `> Integrity#match(sri, [opts]) -> Hash | false`
Returns the matching (truthy) hash if `Integrity` matches the argument passed as
`sri`, which can be anything that [`parse`](#parse) will accept. `opts` will be
passed through to `parse` and [`pickAlgorithm()`](#integrity-pick-algorithm).
##### Example
```javascript
const integrity = 'sha512-9KhgCRIx/AmzC8xqYJTZRrnO8OW2Pxyl2DIMZSBOr0oDvtEFyht3xpp71j/r/pAe1DM+JI/A+line3jUBgzQ7A=='
ssri.parse(integrity).match(integrity)
// Hash {
// digest: '9KhgCRIx/AmzC8xqYJTZRrnO8OW2Pxyl2DIMZSBOr0oDvtEFyht3xpp71j/r/pAe1DM+JI/A+line3jUBgzQ7A=='
// algorithm: 'sha512'
// }
ssri.parse(integrity).match('sha1-deadbeef')
// false
```
#### <a name="integrity-pick-algorithm"></a> `> Integrity#pickAlgorithm([opts]) -> String`
Returns the "best" algorithm from those available in the integrity object.
If `opts.pickAlgorithm` is provided, it will be passed two algorithms as
arguments. ssri will prioritize whichever of the two algorithms is returned by
this function. Note that the function may be called multiple times, and it
**must** return one of the two algorithms provided. By default, ssri will make
a best-effort to pick the strongest/most reliable of the given algorithms. It
may intentionally deprioritize algorithms with known vulnerabilities.
##### Example
```javascript
ssri.parse('sha1-WEakDigEST sha512-yzd8ELD1piyANiWnmdnpCL5F52f10UfUdEkHywVZeqTt0ymgrxR63Qz0GB7TKPoeeZQmWCaz7T1').pickAlgorithm() // sha512
```
#### <a name="integrity-hex-digest"></a> `> Integrity#hexDigest() -> String`
`Integrity` is assumed to be either a single-hash `Integrity` instance, or a
`Hash` instance. Returns its `digest`, converted to a hex representation of the
base64 data.
##### Example
```javascript
ssri.parse('sha1-deadbeef').hexDigest() // '75e69d6de79f'
```
#### <a name="from-hex"></a> `> ssri.fromHex(hexDigest, algorithm, [opts]) -> Integrity`
Creates an `Integrity` object with a single entry, based on a hex-formatted
hash. This is a utility function to help convert existing shasums to the
Integrity format, and is roughly equivalent to something like:
```javascript
algorithm + '-' + Buffer.from(hexDigest, 'hex').toString('base64')
```
`opts.options` may optionally be passed in: it must be an array of option
strings that will be added to all generated integrity hashes generated by
`fromData`. This is a loosely-specified feature of SRIs, and currently has no
specified semantics besides being `?`-separated. Use at your own risk, and
probably avoid if your integrity strings are meant to be used with browsers.
If `opts.strict` is true, the integrity object will be created using strict
parsing rules. See [`ssri.parse`](#parse).
If `opts.single` is true, a single `Hash` object will be returned.
##### Example
```javascript
ssri.fromHex('75e69d6de79f', 'sha1').toString() // 'sha1-deadbeef'
```
#### <a name="from-data"></a> `> ssri.fromData(data, [opts]) -> Integrity`
Creates an `Integrity` object from either string or `Buffer` data, calculating
all the requested hashes and adding any specified options to the object.
`opts.algorithms` determines which algorithms to generate hashes for. All
results will be included in a single `Integrity` object. The default value for
`opts.algorithms` is `['sha512']`. All algorithm strings must be hashes listed
in `crypto.getHashes()` for the host Node.js platform.
`opts.options` may optionally be passed in: it must be an array of option
strings that will be added to all generated integrity hashes generated by
`fromData`. This is a loosely-specified feature of SRIs, and currently has no
specified semantics besides being `?`-separated. Use at your own risk, and
probably avoid if your integrity strings are meant to be used with browsers.
If `opts.strict` is true, the integrity object will be created using strict
parsing rules. See [`ssri.parse`](#parse).
##### Example
```javascript
const integrityObj = ssri.fromData('foobarbaz', {
algorithms: ['sha256', 'sha384', 'sha512']
})
integrity.toString('\n')
// ->
// sha256-l981iLWj8kurw4UbNy8Lpxqdzd7UOxS50Glhv8FwfZ0=
// sha384-irnCxQ0CfQhYGlVAUdwTPC9bF3+YWLxlaDGM4xbYminxpbXEq+D+2GCEBTxcjES9
// sha512-yzd8ELD1piyANiWnmdnpCL5F52f10UfUdEkHywVZeqTt0ymgrxR63Qz0GB7TKPoeeZQmWCaz7T1+9vBnypkYWg==
```
#### <a name="from-stream"></a> `> ssri.fromStream(stream, [opts]) -> Promise<Integrity>`
Returns a Promise of an Integrity object calculated by reading data from
a given `stream`.
It accepts both `opts.algorithms` and `opts.options`, which are documented as
part of [`ssri.fromData`](#from-data).
Additionally, `opts.Promise` may be passed in to inject a Promise library of
choice. By default, ssri will use Node's built-in Promises.
If `opts.strict` is true, the integrity object will be created using strict
parsing rules. See [`ssri.parse`](#parse).
##### Example
```javascript
ssri.fromStream(fs.createReadStream('index.js'), {
algorithms: ['sha1', 'sha512']
}).then(integrity => {
return ssri.checkStream(fs.createReadStream('index.js'), integrity)
}) // succeeds
```
#### <a name="create"></a> `> ssri.create([opts]) -> <Hash>`
Returns a Hash object with `update(<Buffer or string>[,enc])` and `digest()` methods.
The Hash object provides the same methods as [crypto class Hash](https://nodejs.org/dist/latest-v6.x/docs/api/crypto.html#crypto_class_hash).
`digest()` accepts no arguments and returns an Integrity object calculated by reading data from
calls to update.
It accepts both `opts.algorithms` and `opts.options`, which are documented as
part of [`ssri.fromData`](#from-data).
If `opts.strict` is true, the integrity object will be created using strict
parsing rules. See [`ssri.parse`](#parse).
##### Example
```javascript
const integrity = ssri.create().update('foobarbaz').digest()
integrity.toString()
// ->
// sha512-yzd8ELD1piyANiWnmdnpCL5F52f10UfUdEkHywVZeqTt0ymgrxR63Qz0GB7TKPoeeZQmWCaz7T1+9vBnypkYWg==
```
#### <a name="check-data"></a> `> ssri.checkData(data, sri, [opts]) -> Hash|false`
Verifies `data` integrity against an `sri` argument. `data` may be either a
`String` or a `Buffer`, and `sri` can be any subresource integrity
representation that [`ssri.parse`](#parse) can handle.
If verification succeeds, `checkData` will return the name of the algorithm that
was used for verification (a truthy value). Otherwise, it will return `false`.
If `opts.pickAlgorithm` is provided, it will be used by
[`Integrity#pickAlgorithm`](#integrity-pick-algorithm) when deciding which of
the available digests to match against.
If `opts.error` is true, and verification fails, `checkData` will throw either
an `EBADSIZE` or an `EINTEGRITY` error, instead of just returning false.
##### Example
```javascript
const data = fs.readFileSync('index.js')
ssri.checkData(data, ssri.fromData(data)) // -> 'sha512'
ssri.checkData(data, 'sha256-l981iLWj8kurw4UbNy8Lpxqdzd7UOxS50Glhv8FwfZ0')
ssri.checkData(data, 'sha1-BaDDigEST') // -> false
ssri.checkData(data, 'sha1-BaDDigEST', {error: true}) // -> Error! EINTEGRITY
```
#### <a name="check-stream"></a> `> ssri.checkStream(stream, sri, [opts]) -> Promise<Hash>`
Verifies the contents of `stream` against an `sri` argument. `stream` will be
consumed in its entirety by this process. `sri` can be any subresource integrity
representation that [`ssri.parse`](#parse) can handle.
`checkStream` will return a Promise that either resolves to the
`Hash` that succeeded verification, or, if the verification fails
or an error happens with `stream`, the Promise will be rejected.
If the Promise is rejected because verification failed, the returned error will
have `err.code` as `EINTEGRITY`.
If `opts.size` is given, it will be matched against the stream size. An error
with `err.code` `EBADSIZE` will be returned by a rejection if the expected size
and actual size fail to match.
If `opts.pickAlgorithm` is provided, it will be used by
[`Integrity#pickAlgorithm`](#integrity-pick-algorithm) when deciding which of
the available digests to match against.
##### Example
```javascript
const integrity = ssri.fromData(fs.readFileSync('index.js'))
ssri.checkStream(
fs.createReadStream('index.js'),
integrity
)
// ->
// Promise<{
// algorithm: 'sha512',
// digest: 'sha512-yzd8ELD1piyANiWnmdnpCL5F52f10UfUdEkHywVZeqTt0ymgrxR63Qz0GB7TKPoeeZQmWCaz7T1'
// }>
ssri.checkStream(
fs.createReadStream('index.js'),
'sha256-l981iLWj8kurw4UbNy8Lpxqdzd7UOxS50Glhv8FwfZ0'
) // -> Promise<Hash>
ssri.checkStream(
fs.createReadStream('index.js'),
'sha1-BaDDigEST'
) // -> Promise<Error<{code: 'EINTEGRITY'}>>
```
#### <a name="integrity-stream"></a> `> integrityStream([opts]) -> IntegrityStream`
Returns a `Transform` stream that data can be piped through in order to generate
and optionally check data integrity for piped data. When the stream completes
successfully, it emits `size` and `integrity` events, containing the total
number of bytes processed and a calculated `Integrity` instance based on stream
data, respectively.
If `opts.algorithms` is passed in, the listed algorithms will be calculated when
generating the final `Integrity` instance. The default is `['sha512']`.
If `opts.single` is passed in, a single `Hash` instance will be returned.
If `opts.integrity` is passed in, it should be an `integrity` value understood
by [`parse`](#parse) that the stream will check the data against. If
verification succeeds, the integrity stream will emit a `verified` event whose
value is a single `Hash` object that is the one that succeeded verification. If
verification fails, the stream will error with an `EINTEGRITY` error code.
If `opts.size` is given, it will be matched against the stream size. An error
with `err.code` `EBADSIZE` will be emitted by the stream if the expected size
and actual size fail to match.
If `opts.pickAlgorithm` is provided, it will be passed two algorithms as
arguments. ssri will prioritize whichever of the two algorithms is returned by
this function. Note that the function may be called multiple times, and it
**must** return one of the two algorithms provided. By default, ssri will make
a best-effort to pick the strongest/most reliable of the given algorithms. It
may intentionally deprioritize algorithms with known vulnerabilities.
##### Example
```javascript
const integrity = ssri.fromData(fs.readFileSync('index.js'))
fs.createReadStream('index.js')
.pipe(ssri.integrityStream({integrity}))
```

# yallist
Yet Another Linked List
There are many doubly-linked list implementations like it, but this
one is mine.
For when an array would be too big, and a Map can't be iterated in
reverse order.
[![Build Status](https://travis-ci.org/isaacs/yallist.svg?branch=master)](https://travis-ci.org/isaacs/yallist) [![Coverage Status](https://coveralls.io/repos/isaacs/yallist/badge.svg?service=github)](https://coveralls.io/github/isaacs/yallist)
## basic usage
```javascript
var yallist = require('yallist')
var myList = yallist.create([1, 2, 3])
myList.push('foo')
myList.unshift('bar')
// of course pop() and shift() are there, too
console.log(myList.toArray()) // ['bar', 1, 2, 3, 'foo']
myList.forEach(function (k) {
// walk the list head to tail
})
myList.forEachReverse(function (k, index, list) {
// walk the list tail to head
})
var myDoubledList = myList.map(function (k) {
return k + k
})
// now myDoubledList contains ['barbar', 2, 4, 6, 'foofoo']
// mapReverse is also a thing
var myDoubledListReverse = myList.mapReverse(function (k) {
return k + k
}) // ['foofoo', 6, 4, 2, 'barbar']
var reduced = myList.reduce(function (set, entry) {
set += entry
return set
}, 'start')
console.log(reduced) // 'startfoo123bar'
```
## api
The whole API is considered "public".
Functions with the same name as an Array method work more or less the
same way.
There's reverse versions of most things because that's the point.
### Yallist
Default export, the class that holds and manages a list.
Call it with either a forEach-able (like an array) or a set of
arguments, to initialize the list.
The Array-ish methods all act like you'd expect. No magic length,
though, so if you change that it won't automatically prune or add
empty spots.
### Yallist.create(..)
Alias for Yallist function. Some people like factories.
#### yallist.head
The first node in the list
#### yallist.tail
The last node in the list
#### yallist.length
The number of nodes in the list. (Change this at your peril. It is
not magic like Array length.)
#### yallist.toArray()
Convert the list to an array.
#### yallist.forEach(fn, [thisp])
Call a function on each item in the list.
#### yallist.forEachReverse(fn, [thisp])
Call a function on each item in the list, in reverse order.
#### yallist.get(n)
Get the data at position `n` in the list. If you use this a lot,
probably better off just using an Array.
#### yallist.getReverse(n)
Get the data at position `n`, counting from the tail.
#### yallist.map(fn, thisp)
Create a new Yallist with the result of calling the function on each
item.
#### yallist.mapReverse(fn, thisp)
Same as `map`, but in reverse.
#### yallist.pop()
Get the data from the list tail, and remove the tail from the list.
#### yallist.push(item, ...)
Insert one or more items to the tail of the list.
#### yallist.reduce(fn, initialValue)
Like Array.reduce.
#### yallist.reduceReverse
Like Array.reduce, but in reverse.
#### yallist.reverse
Reverse the list in place.
#### yallist.shift()
Get the data from the list head, and remove the head from the list.
#### yallist.slice([from], [to])
Just like Array.slice, but returns a new Yallist.
#### yallist.sliceReverse([from], [to])
Just like yallist.slice, but the result is returned in reverse.
#### yallist.toArray()
Create an array representation of the list.
#### yallist.toArrayReverse()
Create a reversed array representation of the list.
#### yallist.unshift(item, ...)
Insert one or more items to the head of the list.
#### yallist.unshiftNode(node)
Move a Node object to the front of the list. (That is, pull it out of
wherever it lives, and make it the new head.)
If the node belongs to a different list, then that list will remove it
first.
#### yallist.pushNode(node)
Move a Node object to the end of the list. (That is, pull it out of
wherever it lives, and make it the new tail.)
If the node belongs to a list already, then that list will remove it
first.
#### yallist.removeNode(node)
Remove a node from the list, preserving referential integrity of head
and tail and other nodes.
Will throw an error if you try to have a list remove a node that
doesn't belong to it.
### Yallist.Node
The class that holds the data and is actually the list.
Call with `var n = new Node(value, previousNode, nextNode)`
Note that if you do direct operations on Nodes themselves, it's very
easy to get into weird states where the list is broken. Be careful :)
#### node.next
The next node in the list.
#### node.prev
The previous node in the list.
#### node.value
The data the node contains.
#### node.list
The list to which this node belongs. (Null if it does not belong to
any list.)
