Axios
Axios is a popular promise-based HTTP client that offers a more feature-rich alternative to the built-in Fetch API, with automatic JSON parsing and better error handling.
Installing Axios
Making a GET Request
Automatic JSON Parsing
Unlike Fetch, Axios automatically parses JSON responses, eliminating the need to manually call response.json() on every request.
Creating an Axios Instance
Creating a configured instance allows you to set a base URL and default headers once, reducing repetitive code across your application.
Using Interceptors
Axios interceptors allow you to run logic before a request is sent or after a response is received, commonly used for attaching authentication tokens or handling global error responses.
Error Handling with Axios
Axios automatically rejects the promise for HTTP error statuses, simplifying error handling compared to Fetch, which requires manually checking response.ok.
Axios vs Fetch
Axios offers automatic JSON parsing, interceptors, request cancellation, and better default error handling, making it a popular choice for larger applications despite adding an external dependency.
Conclusion
Axios significantly simplifies making HTTP requests in React Native, particularly for applications requiring interceptors, consistent base configuration, and robust error handling across many API calls.
