## What it is
Haul is a command-line tool that serves as a drop-in replacement for the React Native CLI packager, built on Webpack. It can run a development server and bundle React Native apps for production while giving access to the full Webpack ecosystem.

## Use cases
- replace the react-native packager with webpack
- bundle a react native app for production
- run a custom dev server for react native
- use webpack loaders and plugins in react native
- avoid watchman and get symlink support in react native builds

## When to choose
- you need deep Webpack customization for a legacy React Native 0.59+ project
- you want better error messages and symlink support than Metro offered historically

## When to avoid
- starting a new project - the maintainers recommend Re.pack instead
- you need Hot Module Replacement, React Refresh, or Metro feature parity
- you use React Native below 0.59.0 without the legacy branch

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: cli, build-tool, web-framework
- domain: mobile-development, developer-tools, frontend
- platform: cli, cross-platform
- tags: react-native, webpack, bundler, deprecated-in-favor-of-repack, metro-replacement, nodejs
