Sequelize

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 SEMVER. Supports Node v10 and above to use ES6 features.

Quick example

const { Sequelize, Model, DataTypes } = require('sequelize');
const sequelize = new Sequelize('sqlite::memory:');

class User extends Model {}
User.init({
  username: DataTypes.STRING,
  birthday: DataTypes.DATE
}, { sequelize, modelName: 'user' });

sequelize.sync()
  .then(() => User.create({
    username: 'janedoe',
    birthday: new Date(1980, 6, 20)
  }))
  .then(jane => {
    console.log(jane.toJSON());
  });
