Expo Constants vs React Native Config

Developers should use Expo Constants when building React Native apps with Expo to access essential app and device information without platform-specific code, such as for feature toggling, analytics, or conditional rendering based on OS meets developers should use react native config when building react native apps that require environment-specific settings or need to protect sensitive information from being exposed in the repository. Here's our take.

Expo Constants

Nice Pick

Developers should use Expo Constants when building React Native apps with Expo to access essential app and device information without platform-specific code, such as for feature toggling, analytics, or conditional rendering based on OS

Pros

• It simplifies tasks like version checking for updates, identifying devices for debugging, or storing unique installation IDs
• Related to: expo, react-native

Cons

• Specific tradeoffs depend on your use case

React Native Config

Developers should use React Native Config when building React Native apps that require environment-specific settings or need to protect sensitive information from being exposed in the repository

Pros

• It is particularly useful for managing API endpoints, third-party service keys, and feature toggles across different build types, ensuring that configuration changes don't require code modifications
• Related to: react-native, environment-variables

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Expo Constants is a library while React Native Config is a tool. We picked Expo Constants based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Expo Constants wins

Based on overall popularity. Expo Constants is more widely used, but React Native Config excels in its own space.
