## What it is
connect-mongo is a MongoDB-backed session store for Connect and Express, written in TypeScript. It persists server-side sessions in MongoDB with support for automatic expiration cleanup, lazy session updates, and transparent session data encryption.

## Use cases
- store express sessions in mongodb
- persist user sessions across server restarts
- share sessions across multiple node.js server instances
- automatically clean up expired sessions
- encrypt session data at rest in mongodb
- replace in-memory session store with a durable one

## When to choose
- you run an Express or Connect app and need durable, scalable session storage
- you deploy multiple server instances and need a shared session store
- you want MongoDB TTL indexes to handle session expiration automatically
- you need encrypted session payloads

## When to avoid
- you use a framework other than Express/Connect
- you prefer Redis or another session store backend
- your app is a small single-instance prototype where in-memory sessions suffice
- you are not using MongoDB in your stack
