Role-Based Access Control (RBAC)

Summary

Restricting actions or resources based on a user's assigned role (admin, editor, viewer) rather than just whether they're logged in at all.

• 1Add a role field to your user model and gate one route by it.
• 2Build a reusable middleware that checks the required role before allowing a request through.
• 3Design roles with the principle of least privilege — grant only what's needed.
