Environment Variables
Managing environment variables allows React Native applications to use different API URLs, keys, and configuration values across development, staging, and production environments.
Installing react-native-config
Creating Environment Files
Using Environment Variables in Code
Building with a Specific Environment
Never Commit Sensitive Values
Environment files containing secrets or API keys should always be added to .gitignore, with a template file (like .env.example) committed instead to document required variables.
Managing Secrets in CI/CD
For automated builds, environment variables and secrets should be injected securely through your CI/CD platform’s encrypted secrets storage rather than committed environment files.
Type Safety with TypeScript
Conclusion
Properly managing environment variables using react-native-config allows React Native applications to safely and cleanly switch between development, staging, and production configurations across different builds.
