Papr

Papr is a lightweight TypeScript-aware MongoDB ORM that leverages MongoDB's JSON Schema validation for runtime document validation (requires MongoDB 3.6+). Current stable version is 17.1.0, requiring Node.js >=22.12.0 and mongodb driver ^7.0.0. It offers a familiar API similar to raw MongoDB methods but with TypeScript-safe schemas, making it a more type-safe alternative to Mongoose. The library is stable with a moderate release cadence, focusing on performance and minimalism.
