Should I use React Native or Expo?

If you have a project requiring rapid development and have chosen React Native to build cross-platform applications, then Expo is for you .

Build process in details

Run Expo on your own device (iOS) To get it running on your device . Download the Expo Client App on your iOS device, register for a free account or login. When the app starts, there is no clear way to attach to your localhost running project.

If you are already familiar with mobile development, you may want to use React Native CLI. It requires Xcode or Android Studio to get started . If you already have one of these tools installed, you should be able to get up and running within a few minutes.19 Oca 2022
