ts-mongodb

When to Use This Skill

Use when you need to:

• Decide whether a feature's data actually belongs in MongoDB instead of Postgres
• Choose between Mongoose and the native mongodb driver for a Node/TypeScript backend
• Define a MongoDB schema/model with TypeScript types, with or without Mongoose
• Keep ObjectId and driver-specific types out of the rest of the app
• Subscribe to real-time data changes with watch(), or decide that polling is simpler

Trigger keywords: MongoDB, Mongoose, mongodb driver, ObjectId, collection, document, change stream, watch(), aggregation pipeline, NoSQL, ensureIndex, explain(), schema.

Freshness rule: the native driver's typed API (Collection<T>) and Mongoose's TypeScript inference (InferSchemaType) both move across majors — recheck each package's own docs before pinning a version.
