Code with Beto

A quick tip on handling environment variables in React Native and Expo apps. Since mobile apps are client-side and everything gets bundled, secrets like API keys should never be stored in the app. The EXPO_PUBLIC prefix explicitly marks variables as public and extractable. Only use it for non-sensitive identifiers like API endpoints or analytics IDs. Real secrets should be moved to server-side logic.
