Expo vs React Native CLI
When starting a new React Native project, developers must choose between two main approaches: Expo and the React Native CLI. Understanding the difference between these two helps you pick the right workflow for your project needs.
What is Expo?
Expo is a managed framework and set of tools built on top of React Native that simplifies development by handling native configuration automatically. It allows developers to start building apps without installing Android Studio or Xcode.
What is React Native CLI?
React Native CLI is the original, bare-metal way of creating React Native projects, giving developers full control over native code, configuration files, and native dependencies.
Ease of Setup
Expo offers a much faster setup process since it removes the need for native SDK installation initially. React Native CLI requires a fully configured native environment with Android Studio and, for iOS, Xcode.
Native Module Access
Expo’s managed workflow restricts direct access to certain custom native modules unless you use the Expo Development Build. React Native CLI provides unrestricted access to write and integrate any native module you need.
Build and Deployment
Expo provides a cloud build service called EAS Build, which simplifies generating APK, AAB, and IPA files without local native tooling. React Native CLI requires you to configure and manage native builds manually on your local machine.
When to Choose Expo
Choose Expo for rapid prototyping, MVPs, or apps that do not require highly custom native functionality, especially if you want the fastest possible path to a working app.
When to Choose React Native CLI
Choose React Native CLI for apps requiring deep native customization, complex third-party SDK integrations, or full control over the native build process.
Conclusion
Both Expo and React Native CLI are valid ways to build React Native applications. Expo is ideal for speed and simplicity, while React Native CLI offers maximum flexibility and control, making the right choice dependent on your specific project requirements.
