express-routes-mapper

express-routes-mapper

a simple package to map your routes for your expressjs application

Getting started

This is a example for a simple rest API.

1.) npm install

$ npm i -S express-routes-mapper

2.) mapped routes

Create your routes file:

// es6
export default const routes = {

  'POST /user': 'UserController.create'

}

//es5
module.exports.routes = {

  'POST /user': 'UserController.create'

}

Every post request to your server to route '/user' will call the function 'create' on the 'UserController'.

3.) the controller

Create a file named UserController.js

//es6
export default class UserController {

  create (req,res) {

    res.send('created a User with es6');

  }

}

//es5
module.exports = {

  'create': function(req,res){

    res.send('created a User with es5');

  }

}

4.) tell express.js app to use our routes

I assume you have a folder structure like this, but it can be adapted to any folder structure.

.
+-- src
|   +-- config
|   |   +-- routes.js
|   |
|   +-- controllers
|   |   +-- UserController.js
|   |
|   +-- models
|   |
|   app.js
|
package.json

Your app.js could look a bit like this:

The magic happens here:

• import routes from './config/routes'; the file where all the routes are mapped
• import route from 'express-routes-mapper'; the package that makes the mapping possible
• app.use('/', route(routes)); tell express to use the mapped routes

import express from 'express';
import http from 'http';

import routes from './config/routes';
import route from 'express-routes-mapper';

const app = express();
const server = http.Server(app);
const port = process.env.PORT || config.port;

app.use('/', route(routes));

server.listen(port, function() {
  console.log('There we go ♕');
  console.log(`Gladly listening on http://127.0.0.1:${port}`);
});
