REST API Integration
REST (Representational State Transfer) is the most common architectural style used by APIs that React Native applications communicate with. This tutorial explains how to properly integrate REST APIs into your app.
Understanding REST Principles
REST APIs organize functionality around resources, accessed through standard HTTP methods such as GET, POST, PUT, and DELETE, each targeting a specific URL endpoint.
Setting Up an API Service Layer
It is best practice to centralize all API calls in a dedicated service layer rather than scattering fetch or axios calls throughout your components.

Handling Response Status Codes
Understanding common HTTP status codes, such as 200 for success, 401 for unauthorized, 404 for not found, and 500 for server errors, helps you respond appropriately to different API outcomes.
Versioning and Base URLs
Most production APIs include a version in their base URL, such as /api/v1/, which should be configured once in your API service layer rather than repeated across individual requests.
Conclusion
Properly structuring REST API integration with a dedicated service layer keeps your React Native codebase organized, testable, and easier to maintain as your application grows to include more endpoints.
