React Hot Loader 3

This if fork of official repository with this PR has merged: https://github.com/gaearon/react-hot-loader/pull/636 enabling to use ES2015 modules with webpack and without babel (mainly for Typescript)

React Hot Loader 3 beta has arrived!

It fixes some long-standing issues with both React Hot Loader and React Transform.

It is intended as a replacement for both.

Some nice things about it:

• Editing functional components preserves state
• Works great with higher order components
• Requires little configuration
• Automatically disabled in production
• Works with or without Babel (you can remove react-hot-loader/babel from .babelrc and instead add react-hot-loader/webpack to loaders)

Check out the Migration to 3.0 guide to learn how to migrate your app to 3.0.

Installation

npm install --save-dev react-hot-loader@next

Usage

If you want to try hot reloading in a new project, try one of the starter kits.

Provided by owner and collaborators:

• React Hot Boilerplate
• React Hot Loader Minimal Boilerplate

To use React Hot Loader in an existing project, you need to

• switch to Webpack for builds (instead of RequireJS or Browserify);
• enable Hot Module Replacement, which is a Webpack feature;
• configure Webpack to use React Hot Loader for JS or JSX files.

These steps are covered by the Migration to 3.0 guide.

If you'd rather stay with Browserify, check out LiveReactload by Matti Lankinen.

Known limitations

• React Router v3 is not fully supported (e.g. async routes). If you want to get most of React Hot Loader, consider switching to React Router v4 (Note: it's currently in beta!). If you want to understand the reasoning, it's good to start in React Router v4 FAQ

The Talk

React Hot Loader was demoed together with Redux at React Europe. Watch Dan Abramov's talk on Hot Reloading with Time Travel.

React Native

React Native supports hot reloading natively as of version 0.22.

Troubleshooting

If something doesn't work, in 99% cases it's a configuration issue. A missing option, a wrong path or port. Webpack is very strict about configuration, and the best way to find out what's wrong is to compare your project to an already working setup, such as React Hot Boilerplate, bit by bit. We're also gathering Troubleshooting Recipes so send a PR if you have a lesson to share!

Documentation
