Deprecation Notice
React Hot Loader is going to be phased away in favor of the React Transform family of projects. We will soon have a migration guide and a detailed overview, but in the meantime, feel free to check them out and play with them!
React Hot Loader 
This is a stable for daily use in development implementation of React live code editing.
-
Get inspired by a demo video and try the live demo.
-
Use one of the starter kits for your next React project.
The Talk
React Hot Loader was demoed together with Redux at React Europe.
Watch Dan Abramov's talk on Hot Reloading with Time Travel.
Installation
npm install --save-dev react-hot-loader
Usage
If you want to try hot reloading in a new project, try one of the starter kits, React Hot Boilerplate being the most minimal one.
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 walkthrough.
If you'd rather stay with Browserify, check out LiveReactload by Matti Lankinen.
Flux
Redux is a Flux implementation that supports hot reloading of everything out of the box. Read The Evolution of Flux Frameworks for some context around its creation.
React Native
You can use React Hot Loader to tweak a React Native application. Check out react-native-webpack-server by Michael Johnston.
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
Docs are in a bit of a flux right now because I'm in the process of updating everything to document the major 1.0 release.
If you just learned about React Hot Loader and want to find out more, check out the walkthrough and then try one of the starter kits.
If you've been with us for a while, read 1.0 release notes and migration guide.
