What are the best authentication methods for React applications?

There are several popular authentication methods for React apps, including JWT, OAuth, and session-based authentication. Each has its pros and cons.

Can you explain how JWT works in a React app?

Sure! JWT, or JSON Web Tokens, are used to securely transmit information between parties. In a React app, after a user logs in, the server generates a JWT and sends it back to the client, which stores it (usually in local storage) and includes it in the header of subsequent requests.

What about OAuth? How does it differ from JWT?

OAuth is an authorization framework that allows third-party services to exchange information without sharing credentials. Unlike JWT, which is a token format, OAuth is a protocol that can use JWT as a token type.

Which method do you recommend for a new project?

It depends on your project's requirements. If you need third-party integrations, OAuth might be best. For simpler apps, JWT is often sufficient.
