MorphineOrm

MorphineOrm (v0.7.1) is an original Promise-based ORM for Node.js that generates only simple SQL queries (never nested SELECTs). It supports MySQL, MariaDB, PostgreSQL, CockroachDB, SQLite, MSSQL, and Oracle. Features include automatic schema synchronization from model definitions, associations (one-to-one, one-to-many, many-to-one), and virtual attributes. Unlike most ORMs, it uses raw SQL conditions after 'where' instead of a proprietary query language, making it both fast and easy to learn. Released under the MIT license, it has a moderate release cadence with recent updates in 2020.
