How gnelshahnazaryan/eventhub-api works

EventHub is an Express API for account access and event participation: clients authenticate, browse or manage events, join or leave them, and submit or manage attendee reviews. Requests pass through API routing and middleware to controllers, services, repositories, and MongoDB models. The sampled source supports detailed authentication, event, and review flows; user-management internals and some route wiring are represented only at their tree-supported module level.
