How can I secure API endpoints in a React application?

To secure API endpoints in a React application, you can implement authentication and authorization mechanisms, such as JWT (JSON Web Tokens). This ensures that only authenticated users can access certain endpoints.

What is JWT and how does it work?

JWT, or JSON Web Token, is a compact, URL-safe means of representing claims to be transferred between two parties. It consists of three parts: a header, a payload, and a signature. The server generates a token after user authentication, which the client can then use to access protected routes.

Are there any libraries I should use for implementing JWT in React?

Yes, you can use libraries like 'jsonwebtoken' for decoding and verifying JWTs, and 'axios' for making API requests with the token included in the headers.

What about securing the backend API?

For securing the backend API, you should implement middleware to verify the JWT on incoming requests, ensuring that only authorized users can access the API endpoints.
