## Overview

This is a small Express/Mongoose backend for managing wedding events and guests. Clients send HTTP requests to the server, which mounts separate event and guest routes; each route dispatches to its controller, which performs CRUD operations through a Mongoose model and returns JSON responses. The server connects to MongoDB before listening, and uses configuration for the database URL and port. Request and connection activity is logged. The README gives no further product detail; the source establishes the workflows shown here.

Main entry points: [`src/server.ts`](https://github.com/andrej-a/wedding_invitation_backend/blob/main/src/server.ts) (Express server), [`src/routes/Events.ts`](https://github.com/andrej-a/wedding_invitation_backend/blob/main/src/routes/Events.ts) (Event routes), [`src/routes/Guests.ts`](https://github.com/andrej-a/wedding_invitation_backend/blob/main/src/routes/Guests.ts) (Guest routes), [`src/controllers/Events.ts`](https://github.com/andrej-a/wedding_invitation_backend/blob/main/src/controllers/Events.ts) (Event controller)
