# Metro [![CircleCI Build Status](https://circleci.com/gh/facebook/metro.svg?style=shield)](https://circleci.com/gh/facebook/metro) [![npm version](https://badge.fury.io/js/metro.svg)](http://badge.fury.io/js/metro) 🚇 The JavaScript bundler for React Native. - **🚅 Fast**: We aim for sub-second reload cycles, fast startup and quick bundling speeds. - **⚖️ Scalable**: Works with thousands of modules in a single application. - **⚛️ Integrated**: Supports every React Native project out of the box. This project was previously part of the [react-native](https://github.com/facebook/react-native) repository. In this smaller repository it is easier for the team working on Metro Bundler to respond to both issues and pull requests. See [react-native#13976](https://github.com/facebook/react-native/issues/13976) for the initial announcement. ## Installation & Documentation See [the Metro website](https://facebook.github.io/metro/) for documentation.
