TL;DR You can use one of our boilerplates as a base for your project instead.

1. Simulate output of your server in development

Create <project root>/public/YourAppName/index.ejs:

<!doctype html>
<html lang="en">
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title><%= htmlWebpackPlugin.options.title %></title>
    <div id="root"></div>

For details how to write a template, see

2. Add scripts

Put script from RUS to your package.json:

	"scripts": {
		"start": "react-union-scripts start --app YourAppName",
		"build": "react-union-scripts build"

3. Create entry to your application

Code of your <project root>/src/apps/YourAppName/index.js may look like following:

import React from 'react';
import { render } from 'react-dom';

render('Hello World', document.getElementById('root'));

4. Run your project

Development server

yarn start --app YourAppName

Start proxy server

yarn start --app YourAppName --proxy

Production build

Build all registered apps.

yarn build --release

or build just one

yarn build --app YourAppName --release

Running Jest tests

yarn test --release

Analyze build
