Using React Native with Expo: Pros, Cons, and Best Practices

Expo is a set of tools and services built around React Native, aiming to simplify the development process. It allows developers to build native apps using JavaScript and React without dealing with native code.

As a react native cross-platform development company, MetaDesign Solutions has leveraged Expo in several projects. In this blog, I’ll explore the advantages and limitations of using Expo and share best practices.

What is Expo?

• Expo SDK: Provides access to device APIs like camera, location, notifications.
• Expo CLI: Command-line interface for building and running apps.
• Expo Go: An app that lets you run your Expo project on your device instantly.

Pros of Using Expo

1. Simplified Setup

• Quick Start: Get up and running without installing native SDKs.
• No Native Code Required: Ideal for developers without native development experience.

2. Rich API Access

• Device Features: Easy access to native APIs through JavaScript.

3. Over-the-Air Updates

• Instant Updates: Push updates directly to users without app store approvals.

4. Cross-Platform Development

• Universal Apps: Write code once for iOS, Android, and web.

Cons of Using Expo

1. Limited Native Module Support

• Customization Constraints: Can’t add custom native modules unless you eject.

2. Larger App Size

• Bundled Features: Includes all APIs, increasing the app’s size.

3. Ejection Complexity

• Transition Challenges: Ejecting to the bare workflow can be complicated.

Best Practices

Choose the Right Workflow

• Managed Workflow: Stay within Expo’s ecosystem for simplicity.
• Bare Workflow: Eject to gain full control when you need custom native modules.

Keep Dependencies Updated

• Stay Current: Regularly update Expo SDK and related packages.

Optimize Assets

• Asset Management: Use expo-asset to efficiently manage images and other assets.

Use Expo’s Build Service

• Convenience: Leverage Expo’s cloud build service to compile your app.
