Sequelize is a promise-based Node.js ORM for Postgres, MySQL, SQLite and Microsoft SQL Server. It features solid transaction support, relations, read replication and more.

[Stable (v3) documentation](http://docs.sequelizejs.com/en/v3/)

[Master / unstable (v4-pre) documentation](http://docs.sequelizejs.com/en/latest/)

## Installation

`npm install sequelize`

From 3.0.0 and up Sequelize will follow [SEMVER](http://semver.org). 3.0.0 contains important security fixes so we highly recommend that users upgrade.

Starting from 4.0.0 Sequelize will only support Node v4 and above to use ES6 features.

## Features

- Schema definition
- Schema synchronization/dropping
- 1:1, 1:M & N:M Associations
- Through models
- Promises
- Hooks/callbacks/lifecycle events
- Prefetching/association including
- Transactions
- Migrations
- CLI ([sequelize-cli](https://github.com/sequelize/cli))

## Responsible disclosure
If you have any security issue to report, contact project maintainers privately. You can find contact information [here](https://github.com/sequelize/sequelize/blob/master/CONTACT.md)
