Authentication vs. Authorization:

Before we dive into the details, let's clarify the distinction between authentication and authorization:

  • Authentication: This process involves verifying the identity of a user, typically through a username and password or other authentication methods like social logins or single sign-on (SSO).
  • Authorization: Once a user's identity is established, authorization determines what actions and resources they are allowed to access based on their role, permissions, and privileges.

Implementing Authentication in ExpressJS:
  • Middleware: Use middleware to authenticate incoming requests. Popular middleware libraries like Passport.js simplify authentication processes, supporting various strategies such as local, OAuth, and JWT.
  • Session Management: Implement session-based authentication using libraries like Express Session to manage user sessions and track authenticated users.
  • JSON Web Tokens (JWT): Leverage JWT for token-based authentication. Generate and verify tokens to provide secure, stateless authentication across multiple requests.

Implementing Authorization in ExpressJS:
  • Role-Based Access Control (RBAC): Define roles and permissions for users. Implement middleware that checks a user's role before granting access to certain routes or resources.
  • Middleware Chains: Use middleware to implement authorization checks at different levels, ensuring that users have the appropriate permissions for specific actions.
  • Custom Middleware: Create custom middleware to enforce specific authorization logic based on business requirements. For example, verify ownership of a resource before allowing certain actions.
