FAQPage Schema
How do I manage environment variables in an Expo application?

To manage environment variables in an Expo application, you define them in `.env` and `.env.example` files, prefix public variables with `EXPO_PUBLIC_*`, and access them via a typed `lib/env.ts` file for validation and type safety.

How do I set up type-safe access for Expo environment variables?

Type-safe access for Expo environment variables is set up by creating or updating a `lib/env.ts` file, which validates required environment settings and exposes typed variables to your application.

What is the difference between standard and EXPO_PUBLIC_ environment variables?

Standard environment variables remain server-side or build-time only, whereas `EXPO_PUBLIC_*` variables are specifically exposed for client-side availability in your Expo application.

How do I add a new API endpoint to my Expo environment configuration?

To add a new API endpoint to your Expo environment configuration, add the variable to your `.env` and `.env.example` files, prefix it with `EXPO_PUBLIC_` if needed client-side, and update the typed access in `lib/env.ts`.

Can I validate required environment settings before running my Expo app?

You can validate required environment settings before running your Expo app by defining the required checks within the `lib/env.ts` file, ensuring the application fails appropriately if configurations are missing or invalid.

Does this environment configuration approach work with TypeScript Expo projects?

Yes, this environment configuration approach works with TypeScript Expo projects by providing typed access to variables through a dedicated `lib/env.ts` file, ensuring type safety across your application.
