Sequelize
#backend#postgres
Sequelize is a mature ORM for Node.js supporting Postgres, MySQL, SQLite, and others: models, associations, migrations, and a promise-based query API. It predates Prisma’s schema-first workflow and stays popular in brownfield codebases. Choose it when you need a flexible SQL ORM without Prisma’s codegen pipeline; compare trade-offs with Prisma for greenfield TypeScript services.
