How sriyakat/nodejs-auth-system works

This is an Express authentication and product-management API. Clients register, log in, and use access tokens to reach protected profile, admin, and product endpoints; product operations return records through the API. Authentication includes password hashing, token issuance and refresh-token persistence, logout, and password reset. Product CRUD is a separate domain branch, with admin-only writes. The graph follows the sampled route, controller, service, repository, and database layers; product-repository behavior is represented from its indexed database reference, while unsampled details are omitted.
