Getting Started With React Native

Although using React Native seems easy but at the same time can be a bit confusing. First, install React Native:

Using expo-cli:
  • It’s a command-line tool. It helps you to download and install the React Native boilerplate, integrated with expo API. It is one of the simplest ways to build a React Native app, and it’s the recommended way if you’ve just started with React native.
  • Expo-cli gives you many options. You can run and test your application on a mobile device with no configuration. Scan a QR code and your app will open up with the expo mobile app.
Using React-native-cli:
  • The react-native-cli does the same job as expo-cli, but with a fresh approach and extra advantages. React Native-cli offers multiple options and the ability to create native modules in your application. You don’t need to eject your application to make native modules. Ejecting makes you able to use native modules and write your own.
  • Developing React Native apps on different platforms is a unique process. Sometimes we need some specific configuration for a specific platform. Like for Android platform, you can use Android SDK, as shown below:

Using Actual Devices

Nothing is better than using real devices to run and test your app. This is because it lets you know how your application looks like on a real device. You might experience your work seems more practical in a way the virtual device doesn’t provide.

React Native with iOS is way different from Android, although it runs in both platforms very well, with some exceptions.
