express-mongodb

MongoDB-backed session store for express-session. Current stable version is 1.0.0, released in 2025. It targets Node.js >=22 and supports both native MongoDB driver and Mongoose adapters. A modern rewrite of the original Express 2/Mongoose store, it provides ESM and CommonJS compatibility, TypeScript types, and a simple API. Key differentiators include a pluggable adapter pattern, automatic TTL index creation, and deprecated migration helpers for legacy code.
