Getting started

Create a new Nx workspace:

npx create-nx-workspace --cli=nx --preset=empty

Install React Native plugin

# Using npm
npm install --save-dev @nrwl/react-native

# Using yarn
yarn add -D @nrwl/react-native

Create an app

npx nx g @nrwl/react-native:app <app-name>

When using Nx, you can create multiple applications and themes in the same workspace. If you don't want to prefix your commands with npx, install @nrwl/cli globally.

Start the JavaScript bundler

npx nx start <app-name>

This will start the bundler at http://localhost:8081.

Run on devices

Make sure the bundler server is running.

Android:

npx nx run-android <app-name>

iOS: (Mac only)

npx nx run-ios <app-name> --install

Note: The --install flag installs Xcode dependencies before building the iOS app. This option keeps dependencies up to date.

Release build

Android:

npx nx build-android <app-name>

iOS: (Mac only)

No CLI support yet. Run in the Xcode project. See: https://reactnative.dev/docs/running-on-device

Test/lint the app

npx nx test <app-name>
npx nx lint <app-name>

Using components from React library

You can use a component from React library generated using Nx package for React. Once you run:

npx nx g @nrwl/react-native:lib ui-button

This will generate the UiButton component, which you can use in your app.

import { UiButton } from '@myorg/ui-button';
