Zero is a web framework to simplify modern web development. It allows you to build your application without worrying about package management or routing. It's as simple as writing your code in a mix of **Node.js, React, HTML, MDX, Vue, Svelte, Python and putting them all in a folder. Zero will serve them all. Zero abstracts the usual project configuration for routing, bundling, and transpiling to make it easier to get started.

Getting Started

Let's start by making a website that tells us server time.

First we need to create an API endpoint in Node.js to tell us time in JSON.

Create a new folder and add a new file time.js in that folder. In this file, export a function that accepts Request and Response objects (like Express):

// time.js
const moment = require("moment");
module.exports = (req, res) => {
var time = moment().format("LT"); // 11:51 AM
res.send({ time: time });

Once saved, you can cd into that folder and start the server like this:


Running this command will automatically install any dependencies (like momentjs here) and start the web server.

Open this URL in the browser: http://localhost:3000/time

You just created an API endpoint 🎉

Keep the server running. Now let's consume our API from a React page, create a new file index.jsx and add the following code:

// index.jsx
import React from "react";
export default class extends React.Component {
static async getInitialProps() {
var json = await fetch("/time").then(resp => resp.json());
return { time: json.time };
render() {
return <p>Current time is: {this.props.time}</p>;

This is a standard React component. With one additional hook for initial data population:

getInitialProps is an async static method which is called by zero when the page loads. This method can return a plain object which populates props.

Now go to this URL: http://localhost:3000/ and you should see the current server time rendered by React while fetch-ing an API endpoint you created earlier.

zero automatically bundles your code and supports server-side rendering. You don't need to fiddle with webpack anymore.

That's it! You just created a web application.
