Node.js Authentication

Authentication in Node.js applications verifies user identity before granting access to protected resources or routes.

Session-Based Authentication

Session-based authentication stores user state on the server, using cookies to identify returning users across requests.

Token-Based Authentication

Token-based approaches, such as JWTs, allow stateless authentication, making them well-suited for APIs and distributed systems.

Securing Routes

Middleware is commonly used to protect routes, checking for valid sessions or tokens before allowing access to sensitive endpoints.
