Upgrading Expo

Upgrading Expo is a development skill for managing SDK version transitions, covering migration strategies, breaking change identification, and safe upgrade workflows

What Is This?

Overview

Upgrading Expo involves transitioning your React Native project from one SDK version to another while maintaining app stability and functionality. This skill teaches you how to identify breaking changes, follow official migration guides, and handle deprecated APIs systematically. The process ensures your dependencies stay compatible and your codebase remains functional throughout the upgrade journey.

Expo releases new SDK versions regularly with performance improvements, new features, and security updates. Each upgrade may introduce breaking changes that require code modifications. This skill provides structured approaches to navigate these transitions confidently, minimizing downtime and preventing common upgrade pitfalls. Upgrading also keeps your project aligned with the latest community standards and best practices, which can improve maintainability and developer experience. By staying current, you also gain access to new Expo modules, improved APIs, and better support for the latest mobile operating systems.

Who Should Use This

React Native developers using Expo who need to update their projects to newer SDK versions while managing compatibility issues and code changes effectively. Teams maintaining production apps, open-source contributors, and anyone relying on Expo’s managed workflow will benefit from mastering this upgrade process.

Why Use It?

Problems It Solves

Upgrading Expo versions can break existing functionality if not handled carefully. Breaking changes may affect native modules, API signatures, or dependency versions. Without proper guidance, developers waste time debugging unexpected errors. This skill eliminates guesswork by providing clear migration paths and change documentation. It also helps avoid technical debt by ensuring your project does not fall behind on critical updates, which could lead to unsupported dependencies or security vulnerabilities.

Core Highlights

Expo publishes detailed release notes documenting every breaking change and deprecation in each SDK version. The upgrade process involves updating package.json, running installation commands, and testing thoroughly across platforms. Migration guides walk through specific API changes needed for your codebase. Understanding the upgrade timeline helps you plan updates strategically without rushing into unstable versions. Additionally, Expo’s upgrade tools can automate some code modifications, reducing manual effort and the risk of missing important changes.

How to Use It?

Basic Usage

eas update --channel production
expo upgrade
npm install
expo prebuild --clean
eas build --platform all

These commands update your project dependencies, apply necessary code changes, and rebuild your app for all platforms. Always ensure you are running the latest version of the Expo CLI before starting the upgrade process.

Real-World Examples

Upgrading from SDK 49 to SDK 50 requires updating your app.json configuration and checking for deprecated navigation APIs:

{
  "expo": {
    "sdkVersion": "50.0.0",
    "plugins": ["expo-router"]
  }
}
npm install expo@50
expo prebuild --clean

Handling a breaking change in permissions requires updating your code to use the new API:

import * as MediaLibrary from "expo-media-library";
const [status, requestPermission] = 
  MediaLibrary.usePermissions();
await requestPermission();

You may also need to update other dependencies, such as navigation libraries or custom plugins, to ensure compatibility with the new SDK.

Advanced Tips

Always run your test suite after upgrading to catch breaking changes early before deploying to production. Use EAS Build to test your upgrade on real devices before releasing, ensuring native modules compile correctly on both iOS and Android. Consider using feature flags or staged rollouts to minimize risk. Review your CI/CD pipeline to automate upgrade checks and regression testing.

When to Use It?

Use Cases

Upgrading your production app to access new Expo features and security patches released in the latest SDK version. Migrating from an outdated SDK that no longer receives support or security updates. Preparing your codebase for major framework changes before they become mandatory. Evaluating whether new SDK versions introduce dependencies or changes incompatible with your project requirements. Upgrading is also essential when you need to support new device hardware or OS versions.

Related Topics

Understanding EAS Build and deployment workflows complements upgrade knowledge, as does familiarity with React Native version management and native module compatibility. Knowledge of dependency management tools and automated testing frameworks is also helpful.

Important Notes

Requirements

Review the official Expo release notes for your target SDK version before starting. Ensure your project has version control set up so you can revert if issues arise. Test upgrades in a development environment first, never directly on production. Make sure all team members are aware of the upgrade plan and any required code changes.

Usage Recommendations

• Always back up your project and commit all changes to version control before starting an upgrade.
• Carefully read the official Expo release notes and migration guides for each SDK version to understand breaking changes.
• Upgrade dependencies incrementally, especially if skipping multiple SDK versions, to isolate and resolve issues more easily.
• Test your app thoroughly on all supported platforms and devices after upgrading to catch platform-specific regressions.
• Coordinate upgrades with your team to ensure all contributors are aware of new patterns, deprecated APIs, and required code changes.

Limitations

• The upgrade process may not automatically resolve all breaking changes, requiring manual intervention for custom code or third-party libraries.
• Some native modules or custom plugins may lag behind Expo SDK releases, leading to temporary incompatibility or missing features.
• Upgrading across multiple major SDK versions at once increases the risk of complex migration issues and may require additional debugging.
• Automated upgrade tools may not cover edge cases specific to your app’s architecture or unique dependency configurations.
