Sequelize

Sequelize is a promise-based Node.js ORM supporting Postgres, MySQL, MariaDB, SQLite, and Microsoft SQL Server. It offers solid transaction support, relations, eager and lazy loading, read replication, and more. This package (sequelize-hq) is a fork at v5.8.11-0.0.13, adding a safety feature to prevent accidental column deletion on alter sync. It follows SEMVER, requires Node >=6, and ships TypeScript types. Key differentiators include full-featured ORM with multiple database support, active community, and extensive documentation.
