+> Router middleware for [koa](https://github.com/koajs/koa)
+
+* Express-style routing using `app.get`, `app.put`, `app.post`, etc.
+* Named URL parameters.
+* Named routes with URL generation.
+* Responds to `OPTIONS` requests with allowed methods.
+* Support for `405 Method Not Allowed` and `501 Not Implemented`.
+* Multiple route middleware.
+* Multiple routers.
+* Nestable routers.
+* ES7 async/await support.
+
+## Migrating to 7 / Koa 2
+
+- The API has changed to match the new promise-based middleware
+  signature of koa 2. See the
+  [koa 2.x readme](https://github.com/koajs/koa/tree/2.0.0-alpha.3) for more
+  information.
+- Middleware is now always run in the order declared by `.use()` (or `.get()`,
+  etc.), which matches Express 4 API.
+
+## Installation
+
+Install using [npm](https://www.npmjs.org/):
+
+```sh
+npm install koa-router
+```

+
+### Router ⏏
+**Kind**: Exported class  
+<a name="new_module_koa-router--Router_new"></a>
+
+#### new Router([opts])
+Create a new router.
+
+
+| Param | Type | Description |
+| --- | --- | --- |
+| [opts] | <code>Object</code> |  |
+| [opts.prefix] | <code>String</code> | prefix router paths |
+
+**Example**  
+Basic usage:
+
+```javascript
+var Koa = require('koa');
+var Router = require('koa-router');
+
+var app = new Koa();
+var router = new Router();
+
+router.get('/', (ctx, next) => {
+  // ctx.router available
+});
+
+app
+  .use(router.routes())
+  .use(router.allowedMethods());
+```
+<a name="module_koa-router--Router+get|put|post|patch|delete|del"></a>
+
+#### router.get|put|post|patch|delete|del ⇒ <code>Router</code>
+Create `router.verb()` methods, where *verb* is one of the HTTP verbs such
+as `router.get()` or `router.post()`.
+
+Match URL patterns to callback functions or controller actions using `router.verb()`,
+where **verb** is one of the HTTP verbs such as `router.get()` or `router.post()`.
+
+Additionaly, `router.all()` can be used to match against all methods.
+
+```javascript
+router
+  .get('/', (ctx, next) => {
+    ctx.body = 'Hello World!';
+  })
+  .post('/users', (ctx, next) => {
+    // ...
+  })
+  .put('/users/:id', (ctx, next) => {
+    // ...
+  })
+  .del('/users/:id', (ctx, next) => {
+    // ...
+  })
+  .all('/users/:id', (ctx, next) => {
+    // ...
+  });
+```
+
+When a route is matched, its path is available at `ctx._matchedRoute` and if named,
+the name is available at `ctx._matchedRouteName`
+
+Route paths will be translated to regular expressions using
+[path-to-regexp](https://github.com/pillarjs/path-to-regexp).
+
+Query strings will not be considered when matching requests.
+
+#### Named routes
+
+Routes can optionally have names. This allows generation of URLs and easy
+renaming of URLs during development.
+
+```javascript
+router.get('user', '/users/:id', (ctx, next) => {
+ // ...
+});
+
+router.url('user', 3);
+// => "/users/3"
+```
+
+#### Multiple middleware
+
+Multiple middleware may be given:
+
+```javascript
+router.get(
+  '/users/:id',
+  (ctx, next) => {
+    return User.findOne(ctx.params.id).then(function(user) {
+      ctx.user = user;
+      next();
+    });
+  },
+  ctx => {
+    console.log(ctx.user);
+    // => { id: 17, name: "Alex" }
+  }
+);
+```
+
+### Nested routers
+
+Nesting routers is supported:
+
+```javascript
+var forums = new Router();
+var posts = new Router();
+
+posts.get('/', (ctx, next) => {...});
+posts.get('/:pid', (ctx, next) => {...});
+forums.use('/forums/:fid/posts', posts.routes(), posts.allowedMethods());
+
+// responds to "/forums/123/posts" and "/forums/123/posts/123"
+app.use(forums.routes());
+```
+
+#### Router prefixes
+
+Route paths can be prefixed at the router level:
+
+```javascript
+var router = new Router({
+  prefix: '/users'
+});
+
+router.get('/', ...); // responds to "/users"
+router.get('/:id', ...); // responds to "/users/:id"
+```
+
+#### URL parameters
+
+Named route parameters are captured and added to `ctx.params`.
+
+```javascript
+router.get('/:category/:title', (ctx, next) => {
+  console.log(ctx.params);
+  // => { category: 'programming', title: 'how-to-node' }
+});
+```
+
+The [path-to-regexp](https://github.com/pillarjs/path-to-regexp) module is
+used to convert paths to regular expressions.

+# History
+
+## 7.4.0
+
+- Fix router.url() for multiple nested routers [#407](https://github.com/alexmingoia/koa-router/pull/407)
+- `layer.name` added to `ctx` at `ctx.routerName` during routing [#412](https://github.com/alexmingoia/koa-router/pull/412)
+- Router.use() was erroneously settings `(.*)` as a prefix to all routers nested with .use that did not pass an explicit prefix string as the first argument. This resulted in routes being matched that should not have been, included the running of multiple route handlers in error. [#369](https://github.com/alexmingoia/koa-router/issues/369) and [#410](https://github.com/alexmingoia/koa-router/issues/410) include information on this issue.
+
+## 7.3.0
+
+- Router#url() now accepts query parameters to add to generated urls [#396](https://github.com/alexmingoia/koa-router/pull/396)
+
+## 7.2.1
+
+- Respond to CORS preflights with 200, 0 length body [#359](https://github.com/alexmingoia/koa-router/issues/359)

+
+- Backports: merge 5.4 work into the 7.x upstream. See 5.4.0 updates for more details.
+
+## 7.0.1
+
+- Fix: allowedMethods should be ctx.method not this.method [#215](https://github.com/alexmingoia/koa-router/pull/215)
+
+## 7.0.0
+
+- The API has changed to match the new promise-based middleware
+  signature of koa 2. See the
+  [koa 2.x readme](https://github.com/koajs/koa/tree/2.0.0-alpha.3) for more
+  information.
+- Middleware is now always run in the order declared by `.use()` (or `.get()`,
+  etc.), which matches Express 4 API.
+
+## 5.4.0
+
+- Expose matched route at `ctx._matchedRoute`.
+
+## 5.3.0
+
+- Register multiple routes with array of paths [#203](https://github.com/alexmingoia/koa-router/issue/143).
+- Improved router.url() [#143](https://github.com/alexmingoia/koa-router/pull/143)
+- Adds support for named routes and regular expressions

+
+## 5.2.2
+
+- Register routes without params before those with params [#183](https://github.com/alexmingoia/koa-router/pull/183)
+- Fix for allowed methods [#182](https://github.com/alexmingoia/koa-router/issues/182)
+
+## 5.2.0
+
+- Add support for async/await. Resolves [#130](https://github.com/alexmingoia/koa-router/issues/130).
+- Add support for array of paths by Router#use(). Resolves [#175](https://github.com/alexmingoia/koa-router/issues/175).
+- Inherit param middleware when nesting routers. Fixes [#170](https://github.com/alexmingoia/koa-router/issues/170).
+- Default router middleware without path to root. Fixes [#161](https://github.com/alexmingoia/koa-router/issues/161), [#155](https://github.com/alexmingoia/koa-router/issues/155), [#156](https://github.com/alexmingoia/koa-router/issues/156).
+- Run nested router middleware after parent's. Fixes [#156](https://github.com/alexmingoia/koa-router/issues/156).
+- Remove dependency on koa-compose.
+
+## 5.1.1
+
+- Match routes in order they were defined. Fixes #131.
+
+## 5.1.0
+
+- Support mounting router middleware at a given path.
+
+## 5.0.1
+
+- Fix bug with missing parameters when nesting routers.
+
+## 5.0.0
+
+- Remove confusing API for extending koa app with router methods. Router#use()
+  does not have the same behavior as app#use().
+- Add support for nesting routes.
+- Remove support for regular expression routes to achieve nestable routers and
+  enable future trie-based routing optimizations.
+
+## 4.3.2
+
+- Do not send 405 if route matched but status is 404. Fixes #112, closes #114.
+
+## 4.3.1
+
+- Do not run middleware if not yielded to by previous middleware. Fixes #115.
+
+## 4.3.0
+
+- Add support for router prefixes.
+- Add MIT license.
+
+## 4.2.0
+
+- Fixed issue with router middleware being applied even if no route was
+matched.
+- Router.url - new static method to generate url from url pattern and data
+
+## 4.1.0
+
+Private API changed to separate context parameter decoration from route
+matching. `Router#match` and `Route#match` are now pure functions that return
+an array of routes that match the URL path.
+
+For modules using this private API that need to determine if a method and path
+match a route, `route.methods` must be checked against the routes returned from
+`router.match()`:
+
+```javascript
+var matchedRoute = router.match(path).filter(function (route) {
+  return ~route.methods.indexOf(method);
+}).shift();
+```
+
+## 4.0.0
+
+405, 501, and OPTIONS response handling was moved into separate middleware
+`router.allowedMethods()`. This resolves incorrect 501 or 405 responses when
+using multiple routers.
+
+### Breaking changes
+
+4.x is mostly backwards compatible with 3.x, except for the following:
+
+- Instantiating a router with `new` and `app` returns the router instance,
+  whereas 3.x returns the router middleware. When creating a router in 4.x, the
+  only time router middleware is returned is when creating using the
+  `Router(app)` signature (with `app` and without `new`).

+/**
+ * Create `router.verb()` methods, where *verb* is one of the HTTP verbs such
+ * as `router.get()` or `router.post()`.
+ *
+ * Match URL patterns to callback functions or controller actions using `router.verb()`,
+ * where **verb** is one of the HTTP verbs such as `router.get()` or `router.post()`.
+ *
+ * Additionaly, `router.all()` can be used to match against all methods.
+ *
+ * ```javascript
+ * router
+ *   .get('/', (ctx, next) => {
+ *     ctx.body = 'Hello World!';
+ *   })
+ *   .post('/users', (ctx, next) => {
+ *     // ...

+ *   .put('/users/:id', (ctx, next) => {
+ *     // ...
+ *   })
+ *   .del('/users/:id', (ctx, next) => {
+ *     // ...
+ *   })
+ *   .all('/users/:id', (ctx, next) => {
+ *     // ...
+ *   });
+ * ```
+ *
+ * When a route is matched, its path is available at `ctx._matchedRoute` and if named,
+ * the name is available at `ctx._matchedRouteName`
+ *
+ * Route paths will be translated to regular expressions using
+ * [path-to-regexp](https://github.com/pillarjs/path-to-regexp).
+ *
+ * Query strings will not be considered when matching requests.
+ *
+ * #### Named routes
+ *
+ * Routes can optionally have names. This allows generation of URLs and easy
+ * renaming of URLs during development.
+ *
+ * ```javascript
+ * router.get('user', '/users/:id', (ctx, next) => {
+ *  // ...
+ * });
+ *
+ * router.url('user', 3);
+ * // => "/users/3"
+ * ```
+ *
+ * #### Multiple middleware
+ *
+ * Multiple middleware may be given:
+ *
+ * ```javascript
+ * router.get(
+ *   '/users/:id',
+ *   (ctx, next) => {
+ *     return User.findOne(ctx.params.id).then(function(user) {
+ *       ctx.user = user;
+ *       next();
+ *     });
+ *   },
+ *   ctx => {
+ *     console.log(ctx.user);
+ *     // => { id: 17, name: "Alex" }
+ *   }
+ * );
+ * ```
+ *
+ * ### Nested routers
+ *
+ * Nesting routers is supported:
+ *
+ * ```javascript
+ * var forums = new Router();
+ * var posts = new Router();
+ *
+ * posts.get('/', (ctx, next) => {...});
+ * posts.get('/:pid', (ctx, next) => {...});
+ * forums.use('/forums/:fid/posts', posts.routes(), posts.allowedMethods());
+ *
+ * // responds to "/forums/123/posts" and "/forums/123/posts/123"
+ * app.use(forums.routes());
+ * ```
+ *
+ * #### Router prefixes
+ *
+ * Route paths can be prefixed at the router level:
+ *
+ * ```javascript
+ * var router = new Router({
+ *   prefix: '/users'
+ * });
+ *
+ * router.get('/', ...); // responds to "/users"
+ * router.get('/:id', ...); // responds to "/users/:id"
+ * ```
+ *
+ * #### URL parameters
+ *
+ * Named route parameters are captured and added to `ctx.params`.
+ *
+ * ```javascript
+ * router.get('/:category/:title', (ctx, next) => {
+ *   console.log(ctx.params);
+ *   // => { category: 'programming', title: 'how-to-node' }
+ * });
+ * ```
+ *
+ * The [path-to-regexp](https://github.com/pillarjs/path-to-regexp) module is
+ * used to convert paths to regular expressions.
+ *
+ * @name get|put|post|patch|delete|del

+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+  , b = require('debug')('worker:b');
+
+function work() {
+  a('doing lots of uninteresting work');
+  setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+  b('doing some work');
+  setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:

+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+  "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".  If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable.  You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name      | Purpose                                         |
+|-----------|-------------------------------------------------|
+| `DEBUG`   | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY).  |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth.                    |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O`      | Pretty-print an Object on multiple lines. |
+| `%o`      | Pretty-print an Object all on a single line. |
+| `%s`      | String. |
+| `%d`      | Number (both integer and float). |
+| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%`      | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+  return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger 
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :   
+```
+1 false
+2 true
+3 false
+```
+
+Usage :  
+`enable(namespaces)`  
+`namespaces` can include modes separated by a colon and wildcards.
+   
+Note that calling `enable()` completely overrides previously set DEBUG variable : 
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+  // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.
