I’m stuck wiring environment variables into my React Native app at build time. The app runs under Expo and I use EAS Build, but the values I set for the development, Preview, Production profile never make it into the JavaScript bundle. expo's version is the latest. The document of EXPO [login to view URL] I am modifying [login to view URL], [login to view URL] accordingly, though. whatever I set like expo:{ extra: { EXPO_PUBLIC_BUILD: process.env.EXPO_PUBLIC_BUILD, } } and then, eas build --platform android --profile development --clear-cache but I dont see the variable EXPO_PUBLIC_BUILD by doing [login to view URL]("expoConfig", [login to view URL]); or [login to view URL](process.env.EXPO_PUBLIC_BUILD); in tsx files, It always undefined. the document seems not complicated but I cant make it anyways. so I would like you to create a simple example to produce this environment variable correctly.

Hi there, I can help you create a clean, minimal Expo + EAS Build example that correctly injects environment variables into the JavaScript bundle at build time. I’ll set up a simple working flow using `[login to view URL]`, `[login to view URL]`, and Expo’s expected `EXPO_PUBLIC_` variable handling, then show exactly how to verify it with both `[login to view URL]` and `process.env.EXPO_PUBLIC_BUILD` inside a TSX screen. I’ll also check why your current setup returns `undefined`, including common issues like profile-specific env placement, EAS environment configuration, cache behavior, config evaluation timing, and differences between local Expo runs and EAS builds. You’ll get a small reproducible example plus clear steps to build development, preview, and production profiles successfully. Kind regards.

This usually needs to be handled carefully because React Native has separate build flows for Android and iOS, and environment values may need to be injected differently depending on whether you are using bare React Native, Expo, react-native-config, Gradle/Xcode build schemes, CI/CD, or different staging/production builds. You can share your project file and can pay when I am done and will share you output. Thanks!

Hey — saw your post about fixing Expo build environment variables. Getting env vars properly wired at build time can be tricky and often causes issues with config loading or caching. Quick question: Are you currently using the Expo managed workflow or bare workflow for your build? I’ve handled env var setups in multiple Expo projects and know the common pitfalls with build-time injection. Send over your config or build files and I’ll take a look.
