auth-implementation-patterns

JWT access and refresh token patterns use short-lived access tokens with server-side refresh token storage to enable secure session revocation. This approach applies middleware-based token validation and expiry handling to protect REST or GraphQL endpoints.

Enforcing RBAC in Express requires middleware-based authorization checks that validate user permissions and resource ownership before route access. This pattern applies role-based permission validation across protected resources to prevent unauthorized API actions.

Session-based authentication with Redis works by storing server-side session data using secure cookie settings and scalable Redis-backed storage. This mechanism validates session IDs against the datastore to maintain authenticated state across web API requests.

Yes, OAuth2 social login secures API endpoints by implementing Passport-based authorization flows for external identity providers. This process validates OAuth2 tokens and applies permission checks to control access to protected resources.

Authentication and authorization middleware require guardrails like token expiry handling, rate limiting for auth endpoints, and secure cookie practices. These precautions prevent brute force attacks and ensure expired or revoked tokens are correctly rejected.

Choose JWT for stateless API authentication when you need short-lived access tokens with refresh capabilities, while session-based authentication suits scenarios requiring scalable Redis-backed server-side session storage and immediate revocation.
