Notice

We’re actively working on a Haul successor, which would provide long awaited features like Hot Module Replacement + React Refresh and better feature-parity with Metro. The version 1.0.0 is already released!

If you’re investigating using Haul, we highly recommend giving a Re.pack a go.

If you’re already using Haul, we recommend migrating to Re.pack for better developer experience and feature set. The migration process is fairly straighforward, since you now have full access to webpack.config.js.

Haul is a drop-in replacement for react-native CLI built on open tools like Webpack. It can act as a development server or bundle your React Native app for production.

@haul-bundler/cli and other packages under @haul-bundler scope are a overhaul of haul package and support only React Native 0.59.0 and above. If you need to support older versions, please check legacy branch.

@haul-bundler/cli and other packages requires Node 10 to be installed. If you’re running older version, please upgrade to Node 10 LTS or newer.

Features

  • Replaces React Native packager to bundle your app
  • Access to full webpack ecosystem, using additional loaders and plugins is simple
  • Doesn’t need watchman, symlinks work nicely
  • Helpful and easy to understand error messages

Getting started

Start by adding Haul as a dependency to your React Native project (use react-native init MyProject to create one if you don’t have a project):

  1. yarn add --dev @haul-bundler/cli
  3. # Traditionalist? No problem:
  4. npm install --save-dev @haul-bundler/cli

To configure your project to use haul, run the following:

  1. yarn haul init
  2. # npm >= 5.2.0 :
  3. npx haul init
  4. # npm < 5.2.0 :
  5. npm install -g npx
  6. npx haul init

This will automatically add the configuration needed to make Haul work with your app, e.g. add haul.config.js to your project, which you can customize to add more functionality.

Next, you’re ready to start the development server:

  1. yarn haul start
  2. # Or:
  3. npx haul start

Finally, reload your app to update the bundle or run your app just like you normally would:

  1. react-native run-ios

Limitations

Haul uses a completely different architecture from React Native packager, which means there are some things which don’t work quite the same.

  • Delta Bundles (RN 0.52+) have minimal support
  • Existing react-native commands
  • No support for Hot Module Replacement

The following features are unlikely to be supported in the future:

  • Haste module system: use something like babel-plugin-module-resolver instead
  • Transpile files under node_modules: transpile your modules before publishing, or configure webpack not to ignore them
