JETX a NodeJS HTTP routing library

just a tiny http server inspired by express


Do you ever use express.js? well, it is the most popular NodeJs framework to build web service. This project is just a way to show how we can build a library like that, while also demonstrating how NodeJS work. It consists of a routing system and middleware only, nothing more. The routing part is run on top of my own simple EventEmitter container, and it just a single-segment URL pattern matching using array filtering, well that is bad, for demonstration purpose, I don't want to make it complicated. NodeJS itself has already provided the better EventEmitter package, but I just want to show, how the concept works.


  • Simple Routing
  • Middleware
  • Built in 404 error response

Install/ How to use

Make sure you have NodeJS (latest version is recommended) installed in your local.

If you get this source from zip version or direcly clone from github repository, you can just run the example app with this command:

    $ npm start

Install into your own NodeJS project Using NPM

    $ npm install jetx

Example/ how to use

  • create a file for example: index.js

  • write these codes in the file:

    const jetx = require('./index');
    const app = new jetx();
    app.get('/', function(req, res) {
        res.send(`<h1>hello world from JetX</h1>
            This is the the index page.
            <br> This lib came with simple routing, middleware, and default 404 error page.
            <br> Go try to hit an undefined route such as, <a href="http://localhost:8080/xxx">here</a>
    app.get('/test', function(req, res) {
        const result = {
            id: 1,
            name: "erdi",
    });'/', function(req, res) {
        res.send('this is the post response');
    // using middleware
    const mymiddleware = (req, res) => {
        console.log('incoming request', (new Date).getTime(), req.url)
    app.listen(8080, function() {
        console.log('server is running')

now run :

    node index.js
