classy-router

Class based HTTP router

Lightweight, has only debug and path-to-regexp dependencies. It is compatible with Express 4, Hapi or simple HTTP server.

This module is a follow-up of ES6 Class based Express routing blog post.

Installation

npm install classy-router -S

Usage

Instead of writing app.get('/', function() {}); or server.router({ method: 'GET', path: '/', handler: function() {}}) to define request handlers, you use a Class to hold methods registered as route handlers to the underlying framework, Express or Hapi.

Additionnaly, it implements a simple routing mechanism with raw HTTP server.

import ClassyRouter from 'classy-router'

class Router extends ClassyRouter {
  get routes() {
    '/': 'index'
  }

  index(req, res) {
    console.log('Incoming request:', req.url);
    return res.send('Response from server');
  }
}

Express

var app = require('express')();
var router = new Router(app);
app.listen(3000);

Or

var app = require('express')();
app.use(Router.middleware(app));
app.listen(3000);

Standard http server

var router = new Router();
router.listen(3000);

Or

var http = require('http');
http.createServer(Router.middleware()).listen(3000);

Or

Router.createServer().listen(3000);

Or

Router.listen(3000);
