JWT Authentication in Next.js APIs
A recent tutorial covered implementing secure authentication using JWTs in Next.js API endpoints, emphasizing statelessness.
The tutorial likely walks through setting `Authorization` headers in Next.js API routes to validate JWTs. This ensures only authenticated users can access protected resources. Statelessness, achieved by verifying the JWT on each request, contrasts with session-based authentication. The server doesn't need to maintain user session data, improving scalability. However, consider the trade-offs: every API request incurs the overhead of JWT verification. This can impact performance, especially with frequent API calls.
