React Native CLI

Command line tools that ship with react-native in form of the @react-native-community/cli package.

It exposes react-native binary, so you can call yarn react-native or npx react-native directly from your project.

Note: CLI has been extracted from core react-native as a part of "Lean Core" effort. Please read this blog post for more details.

About

This repository contains tools and helpers for React Native projects in form of a command line tool. There's been quite some confusion around that since the extraction from React Native core. Let's clear them up:

  • There are currently two CLIs:
  • When we say "the CLI" we mean @react-native-community/cli.
  • We update the CLI independently of React Native itself. Please see how to use the latest version.
  • This is a monorepo to keep stuff organized.

We're actively working to make any indirections gone.

Creating a new React Native project

There are two ways to start a React Native project.

Using npx (recommended)

Available since react-native@0.60

This method is preferred if you don't want to install global packages.

npx react-native init MyApp

Usage in an existing React Native project

Once you're inside an existing project, a local react-native binary will be available for you to use. Feel free to use Yarn to call it directly.

Example running start command in terminal:

yarn react-native start
# or:
npx react-native start
# or
node ./node_modules/.bin/react-native start

You can also add npm scripts to call it with whichever package manager you use:

{
  "scripts": {
    "start": "react-native start"
  }
}

Updating the CLI

React Native CLI is a dependency of react-native, which makes it a transitive dependency of your project. It happens that you may be locked on a version without fixes for bugs that may affect you. Here's how to get it sorted:

  1. If you use lock files (yarn.lock or package-lock.json) - find all the @react-native-community/cli prefixed entries, remove them, run yarn install / npm install once again. Here's an example using yarn.lock. Notice how whole @react-native-community/cli entries are removed. Make sure to delete all of them:

    diff --git a/yarn.lock b/yarn.lock
    index 073309f..0bb8c4b 100644
    --- a/yarn.lock
    +++ b/yarn.lock

  2. If you don't use lock files – remove node_modules and run yarn install / npm install again.

  3. Run yarn list --pattern @react-native-community/cli or npm list @react-native-community/cli and verify you're on the latest version.

After performing these steps you should be on the latest CLI version. Feel free to do it once in a while, because we release often.
