mongoose-extend-schema

A lightweight utility (v1.0.0, no recent updates) that extends a Mongoose schema by merging its fields with additional definitions. Unlike mongoose-extend-schema, native Mongoose does not provide a built-in schema inheritance method; this package offers a simple shallow merge approach. It is installed from npm, requires Node >=8.2.1 and Mongoose as a peer dependency. While straightforward, it has known issues: it only shallow-copies schema fields, does not copy indexes or other schema options, and can cause silent overrides if field names conflict. Use with caution for simple schema extension needs.
