guards
NestJS Guards
When to Use This Skill
Use this skill when:
- Implementing authentication (verifying user identity)
- Implementing authorization (checking user permissions/roles)
- Protecting routes based on user roles or permissions
- Validating JWT tokens or API keys
- Implementing custom access control logic
- Restricting access based on request context
- Building role-based access control (RBAC) systems
- Implementing feature flags or conditional route access
What are Guards?
Guards determine whether a request will be handled by the route handler. They implement the CanActivate interface and return a boolean value (or Promise/Observable) indicating whether access is allowed.
Guards execute after middleware but before interceptors and pipes in the request lifecycle.
