Node.js object-relational mapper
Sequelize is an open-source object-relational mapper for Node.js that maps JavaScript or TypeScript classes to SQL tables across PostgreSQL, MySQL, MariaDB, SQLite and SQL Server.
It handles models, associations, migrations, transactions and query building so application code works with objects, while still allowing raw SQL when a query needs to be written by hand.
Sequelize remains common in established Node.js codebases, while newer projects often start on Prisma, Drizzle or TypeORM. Maintenance and migration work is the bulk of demand, so screen for people comfortable in an existing schema.
