A new Webpack boilerplate with:

• hot reloading React components;
• error handling inside component render() function;
• error handling for syntax errors (thanks, @glenjamin!)

Built with babel-plugin-react-transform and a few custom transforms.
Does not use React Hot Loader.

git clone https://github.com/gaearon/react-transform-boilerplate.git
cd react-transform-boilerplate
npm install
npm start
open http://localhost:3000

Then go ahead and edit files inside src (any file except index.js).

The component instrumentation is implemented on top of babel-plugin-react-transform:

• react-transform-hmr handles hot reloading
• react-transform-catch-errors catches component errors

The syntax errors are displayed in an overlay by @glenjamin’s webpack-hot-middleware which replaces Webpack Dev Server.

This boilerplate is just a Webpack bundle served by an Express server. It’s not meant to demonstrate every feature of either project. Please consult Webpack and Express docs to learn how to serve images, or bundle them into your JavaScript application.

Make sure your react-app is not attached to document.body as the client overlay provided by webpack-hot-middleware will render into document.body. Attaching the React root node to document.body requires extra caution, as many third-party packages will append their markup to the body as well. React will replace the entire contents in the body on every re-render. Thus you will not see the additional markup.

It’s always better to render your React app in a #root DOM element.

import React from 'react'
import { App } from 'app'

React.render(<App />, document.getElementById('root'))
