How geovanesv/user-service-rabbitmq works

This NestJS user microservice supports user registration and JWT-protected lookup, plus email/password and Passport login, token validation and refresh, profile, and logout routes. Registration checks for duplicates, hashes and stores the password, then publishes a user.created event for downstream consumers. Authentication verifies users through the user service and issues JWTs. The graph shows PostgreSQL and RabbitMQ as external systems; implementation details for some documented authentication routes and strategies are not fully sampled, so their internal flows are not expanded.
