## Overview

This is a TypeScript/Express social-media backend. Its main request path is HTTP client → mounted feature controller → service logic → MongoDB/Redis or supporting integrations → JSON response; authentication middleware verifies tokens and sessions along the way. The feature map covers account confirmation and login, profiles and friendships, posts and follows, and chat/realtime infrastructure. The README gives no product detail, so feature scope comes from the source tree and indexed imports; chat event wiring is unsampled and shown only as unverified.
