Sequelize is a promise-based Node.js ORM for Postgres, MySQL, MariaDB, SQLite and Microsoft SQL Server. It features solid transaction support, relations, eager and lazy loading, read replication and more. Sequelize follows Semantic Versioning.
New to Sequelize? Take a look at the Tutorials and Guides. You might also be interested in the API Reference.
Due to personal reasons a bigger part of the former core maintainers (thanks to all your hard work!) have been rather busy recently. Hence, the available time to look after our beloved ORM has been shrinking and shrinking drastically, generating a great chance for you:
We are looking for more core maintainers who are interested in finishing the current TypeScript migration, extending the documentation for v6, organizing issues, reviewing PRs, streamlining the overall code base and planning the future roadmap.
If that sounds interesting to you, please reach out to us on Slack. We are looking forward to meet you!
v6 release is now available under @latest tag. You can find detailed changelog here.
Note: master branch points to experimental version not suitable for production. All documentation PRs should be opened for v6 branch. All bug-fix / feature PRs should be opened for master branch first, then for their release target branches i.e. v6 or v5.
