How do I implement authentication in a single-page application?
To implement authentication in a single-page application (SPA), you can use token-based authentication, such as JWT.
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: header, payload, and signature.
Are there any libraries you recommend for handling JWT in SPAs?
Yes, libraries like 'jsonwebtoken' for Node.js and 'jwt-decode' for decoding JWTs in the browser are popular choices.
What about securing API endpoints?
You should secure your API endpoints by validating the JWT on the server side and ensuring that only authenticated users can access protected routes.
