The missing router features for [eggjs](https://eggjs.org)

## Install

```bash
$ npm i egg-router-plus --save
```

Then mount plugin:

```js
// {app_root}/config/plugin.js
exports.routerPlus = {
  enable: true,
  package: 'egg-router-plus',
};
```

## Features

### load `app/router/**/*.js`

this plugin will auto load router define at `app/router/**/*.js`.

**Notice: all sub routers will be loaded before `app/router.js`, please ensure all the sub router definitions are not conflict(better to use `app.router.namespace` to create different namespaces for each sub router file).**

### app.router.namespace

```js
app.router.namespace(prefix, ...middlewares);
```

- `prefix` - {String}, the prefix string of sub router
- `middlewares` - {...Function}, optional group middlewares

Support same as Router:

- `router.verb('path-match', app.controller.action);`
- `router.verb('path-match', middleware1, ..., middlewareN, app.controller.action);`
- `router.verb('router-name', 'path-match', app.controller.action);`
- `router.verb('router-name', 'path-match', middleware1, ..., middlewareN, app.controller.action);`

Note: `prefix` and `path` are not allow to be `regex`, and `prefix` can't be '/'.

```js
// {app_root}/app/router.js
module.exports = app => {
  const subRouter = app.router.namespace('/sub');
  // curl localhost:7001/sub/test
  subRouter.get('/test', app.controller.sub.test);
  subRouter.get('sub_upload', '/upload', app.controller.sub.upload);

  // const subRouter = app.router.namespace('/sub/:id');
  // const subRouter = app.router.namespace('/sub', app.middleware.jsonp());

  // output: /sub/upload
  console.log(app.url('sub_upload'));
};
```

## Known issues

- sub `redirect` is not support, use `app.router.redirect()` or redirect to a named router.

```js
const subRouter = app.router.namespace('/sub');

// will redirect `/sub/go` to `/anyway`, not `/sub/anyway`
subRouter.redirect('/go', '/anyway');

// just use router
router.redirect('/sub/go', '/sub/anyway');

// or redirect to a named router
subRouter.get('name_router', '/anyway', app.controller.sub.anyway);
// will redirect `/sub/go_name` to `/sub/anyway` which is named `name_router`
subRouter.redirect('/sub/go_name', 'name_router');
```
