Marpat

Marpat is a lightweight ES6 class-based ODM (Object Document Mapper) for MongoDB and NeDB, forked from Camo. It provides a storage-agnostic document collection backend with schema validation via Joi since v3.0.0. Current stable version is 3.0.5, with a release cadence of several months. Supports hooks, embedded documents, counting, and custom database drivers. Key differentiators: ES6 class syntax, support for NeDB (file or in-memory) and MongoDB, integrated Joi validation, and a client registry for custom backends. Requires Node >=8.
