Simplify API Requests and Enhance Responses with Axios Interceptors

Axios is a popular and powerful javascript library that provides simplify process to make HTTP requests from web application or node JS. One of its key features is interceptors, which allow developers to handle and modify requests and responses globally. Axios Interceptors act like a middleware between request and response, allowing developers to modify data before it send or received. In this article, we'll explore the benefits of using Axios Interceptors to enhance API requests and streamline error handling.

Setting a Base URL: One of the advantages of Axios interceptors is the ability to set a base URL for all API requests. By defining a base URL, developers can easily switch between different environments, such as development, staging, and production, by modifying a single configuration value.

Authentication: Axios interceptors allow developers to centralize the authentication process by automatically adding authentication tokens or credentials to outgoing requests. With the base URL already set, developers can easily append the authentication information to each API call, making the authentication process seamless and consistent.

Request Transformation and Header Management: With Axios interceptors, developers can transform request data before it is sent to the server and easily manage headers. This is particularly useful when standardizing data formats, performing data validation, or adding custom headers to API requests. By leveraging the base URL feature, developers can apply these transformations and headers globally, ensuring consistency and reducing repetitive code.

Error Handling Made Easy: Handling API errors consistently can be a challenging task. Intercepting responses with Axios enables developers to implement a unified error handling mechanism. By checking response status codes, developers can automatically handle common errors, display meaningful error messages or take any action based on response status code.
