How do I securely manage API keys and database credentials in an Expo application?

Securely manage API keys in Expo by implementing server-side API routes to handle sensitive operations. This ensures database credentials and tokens remain protected within the server environment rather than being exposed to the client.

Can I create a proxy endpoint in Expo Router to call third-party APIs like Stripe?

Yes, you can create secure proxy endpoints within Expo Router to interact with third-party APIs. This approach facilitates secure integration with services like Stripe or OpenAI without exposing your secret environment variables to the mobile client.

How do I deploy Expo API routes to a serverless backend?

Deploy Expo API routes to a serverless backend using EAS Hosting. This deployment streamlines the process to Cloudflare Workers while providing built-in support for managing your production environment variables and adhering to runtime constraints.

Does EAS Hosting support environment variables for Expo API routes?

Yes, EAS Hosting supports environment variables for Expo API routes. Proper environment variable configuration is required to securely handle server-side logic, database access, and third-party API integration during production deployment.

When should I use server-side API routes instead of client-side logic in Expo?

Use server-side API routes in Expo when you need to handle sensitive operations, perform server-side validation, or manage database access. This ensures that your backend logic and sensitive data remain protected from the client environment.

What are the limitations of Expo API routes on EAS Hosting?

Expo API routes on EAS Hosting are constrained by the platform's specific runtime limits. You must adhere to EAS Hosting runtime constraints and configure environment variables properly to ensure your serverless backend functions correctly in production.
