RESTful API Authentication and Access Control in NodeJS

Security is a paramount concern when building reliable APIs. In this article, I break down how to implement robust authentication and access control for RESTful services without relying on session cookies.

Key Concepts Covered

1. Stateless Authentication: Why JWTs are preferred for microservices and mobile backends.
2. Middleware Implementation: Creating reusable Express middleware to protect routes.
3. Password Hashing: Proper usage of bcrypt to store credentials securely.
4. Role-Based Access Control (RBAC): How to restrict endpoint access based on user roles (Admin, User, etc).

This guide walks you through setting up the project, defining the user schema, and handling the login flow to issue tokens securely.

"Authentication is not just about logging in; it's about identifying who is on the other end of the request."
