Node is a JavaScript "runtime environment" that lets you run JavaScript from your Terminal (and other places outside of a browser). You can check if you already have Homebrew installed by running brew -version in your Terminal. Plus, it's just super handy for installing other things you may need! We will need it to install some of the dependencies for React Native. Homebrew is billed as "the missing package manager" for macOS and is widely used by developers. One of the most important tools on macOS is called Homebrew.
It'll allow us to compile Android apps, set up Android emulators, and also run our React Native project in Android Studio to take advantage of its powerful features if we want. Lastly, while we generally recommend running our React Native app from the terminal (more information on this in the last chapter of this blog!) we can also load up our React Native app in Xcode and run it from there, which lets us use all of the powerful features that Xcode has to offer.Īndroid Studio is Google's IDE (integrated development environment) for Android app development. Xcode also comes with an iOS "simulator", which lets us run iOS apps on our Mac to see how they'll look and function. We need it for React Native in order to use its build tools, which allows us to compile the native code necessary to build React Native apps. It supports the Objective-C and Swift languages. Xcode is Apple's IDE (integrated development environment) for building Mac, iOS, watchOS, and tvOS apps.
