Sequelize

A feature-rich, promise-based Node.js ORM supporting PostgreSQL, MySQL, MariaDB, SQLite, and Microsoft SQL Server.

Sequelize bridges the gap between JavaScript objects and relational databases: it handles the heavy lifting of SQL generation so you focus on application logic. It provides robust support for transactions, eager loading (using the 'include' property), and database migrations. The library scales from simple SQLite prototypes to massive PostgreSQL clusters: use 'Model.init' to define schemas and 'sequelize.sync' to keep tables aligned. Its extensive plugin ecosystem and TypeScript compatibility make it a reliable standard for enterprise-grade Node.js backends.
