Lesson 1: Introduction to Expo

Introduction to Expo

Expo is an open-source platform that allows you to build React Native apps quickly and efficiently. It comes with a set of tools and services that help you develop, build, deploy, and quickly iterate on iOS, Android, and web apps from the same codebase.

Benefits of Using Expo:

• Faster Development: Expo provides a rich set of APIs and components that speed up the development process.
• Cross-Platform: Write once, run on both iOS and Android.
• Simplified Workflow: Built-in support for push notifications, camera, location services, and more.
• Instant Updates: Push updates to your app without going through the app store.

Limitations of Using Expo:

• Custom Native Modules: Limited to the modules provided by Expo unless you eject.
• Performance: May not match the performance of fully native apps for very complex use cases.

Real-World Scenario: For our “JUST-Learning” app, Expo can help us quickly develop and deploy features such as course content delivery, user authentication, and more, allowing us to focus on the core functionality of our platform.

Conclusion: Expo is a powerful tool for rapid mobile app development, providing a robust set of features and services that streamline the development process. While there are some limitations, its benefits make it an excellent choice for many applications.
