Iridium

Iridium is a lightweight, TypeScript-first ORM for MongoDB designed for power-users who want fine-grained control over database interactions. The current stable version is 7.2.5, with a low release cadence (last release in 2019). It provides a bare-bones abstraction over the MongoDB driver, supporting schema validation, pre/post hooks, and minimal magic. Compared to Mongoose, Iridium offers less built-in convenience but greater transparency and performance for advanced use cases. It ships with TypeScript definitions and requires Node.js >= 6. It is ideal for projects that need a thin wrapper without heavy opinionation.
