Expressive and maintainable routes for Express.js.



Running the example

-----



The project includes a simple example rendering a `/` and `/api/posts` endpoint,

you can set it up as follows:



```bash

$ cd ./example

$ yarn

$ yarn start

```



Now visit `http://localhost:3000` and take a look at `server.js`!



Usage

-----



__Basic usage__



You pass your Express app to Torch, and a callback in which you can 

specify your routes.



```js

import Express from 'express';

import Torch from 'express-torch';

import HomeController from './controllers/home';



const app = Express();



Torch(app, (router) => {

    router.get('/', HomeController.index);

});



//... your other Express logic



app.listen(3000);

```



__Grouping__



This is where Torch shines, you can register a bunch of routes

that require all parameters of the groups above, such as a `prefix` for

your `/api` routes.



```js

import Express from 'express';

import Torch from 'express-torch';

import HomeController from './controllers/home';



const app = Express();



Torch(app, (router) => {

    router.get('/', HomeController.index);

    router.group({prefix: 'api'}, (router) => {

        router.get('/posts', HomeController.index);// will evaluate to /api/posts

        router.get('/posts/:id', HomeController.show);// will evaluate to /api/posts/:id

    });

});



//... your other Express logic



app.listen(3000);

```



__Middleware__



Groups have another advantage, you can apply regular Express middleware to them,

so that they stack together without you having to specify them per route



```js

import Express from 'express';

import Torch from 'express-torch';

import HomeController from './controllers/home';



const app = Express();



Torch(app, (router) => {

    router.group({middlware: [Cookies, Session]}, (router) => {

    router.get('/', HomeController.index);// Cookies > Session

    router.group({middleware: [Throttle]}, (router) => {

        router.get('/posts', HomeController.index);// Cookies > Session > Throttle

        router.group({middleware: [OAuth, Policy('manage-posts')]}, (router) => {

            router.get('/posts/:id', HomeController.show);// Cookies > Session > Throttle > OAuth > Policy('manage-posts')

        });

    });

});



//... your other Express logic



app.listen(3000);

```



if you want, you can still apply middleware to a single route



```js

import Express from 'express';

import Torch from 'express-torch';

import HomeController from './controllers/home';



const app = Express();



Torch(app, (router) => {

    router.get('/', {,

        middleware: [Auth],

        controller: HomeController.index

    });

});



//... your other Express logic



app.listen(3000);

```



__Naming__



Since urls can be subject to your client's requests you don't want to spread

them all around your application as if they were static. Torch allows you to

add a mapping so that some `name` will map to a path.



```js

import Express from 'express';

import Torch from 'express-torch';

import PostsController from './controllers/posts';



const app = Express();



const routes = Torch(app, (router) => {

    router.group({prefix: '/api'}, function(router) {

        router.get('/posts/:id', {,

            name: 'api.posts.show',

            controller: PostsController.show

        });

    });

});



routes.named('api.posts.show',  { id: 123 });// will evaluate to /api/posts/123



//... your other Express logic



app.listen(3000);



/**** in ./controllers/posts.js ****/



{

    index: (req, res) => {

        req.routes.named('api.posts.show', {id: 123}) 

    }

}

```



__Constraints__



Most of the time we want to constrain our routes their variables, for example an `:id` should in some applications only match a number. Express allows us to use regex inside a route path but those make the route look bloated and hard to read. To still be able to constrain our routes but still keep them readable Torch allows us to define the constraints in an extra method.



```js

import Express from 'express';

import Torch from 'express-torch';

import PostsController from './controllers/posts';



const app = Express();



const routes = Torch(app, (router) => {

    router.group({prefix: '/api'}, function(router) {

        router.get('/posts/:id', PostsController.show).where({'id', '(\\d+)'}); // will evaluate to /api/posts/:id(\\d+)

    });

});



//... your other Express logic



app.listen(3000);

```
