Dependencies for Mac

You will need Xcode for iOS and Android Studio for android, node.js, the React Native command line tools, and Watchman.

We recommend installing node and watchman via Homebrew.

Watchman is a tool by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance. It is optional.

Node comes with npm, which lets you install the React Native command line interface.

If you get a permission error, try with sudo:

For iOS the easiest way to install Xcode is via the Mac App Store. And for android download and install Android Studio.

If you plan to make changes in Java code, we recommend Gradle Daemon which speeds up the build.

Testing your React Native Installation

Use the React Native command line tools to generate a new React Native project called 'AwesomeProject', then run react-native run-ios inside the newly created folder.

You should see your new app running in the iOS Simulator shortly. react-native run-ios is just one way to run your app - you can also run it directly from within Xcode or Nuclide.

Modifying your app

Now that you have successfully run the app, let's modify it.

• Open index.ios.js or index.android.js in your text editor of choice and edit some lines.
• Hit Command⌘ + R in your iOS Simulator to reload the app and see your change! That's it!

Congratulations! You've successfully run and modified your first React Native app.
