Sequelize: how to import definitions from an existing database

This project aims to create Sequelize models from existing schema https://github.com/sequelize/sequelize-auto

Sequelize-Auto

A tool to automatically generate models for SequelizeJS via the command line.

Install:

npm install -g sequelize-auto

Usage:

sequelize-auto -h <host> -d <database> -u <user> -x [password] -p [port]  --dialect [dialect] -c [/path/to/config] -o [/path/to/models]

Options:

  -h, --host      IP/Hostname for the database.                                      [required]
  -d, --database  Database name.                                                     [required]
  -u, --user      Username for database.                                             [required]
  -x, --pass      Password for database.
  -p, --port      Port number for database.
  -c, --config    JSON file for sending additional options to the Sequelize object.
  -o, --output    What directory to place the models.
  -e, --dialect   The dialect/engine that you're using: postgres, mysql, sqlite

Example

sequelize-auto -o "./models" -d sequelize_auto_test -h localhost -u daniel -p 5432 -x my_password -e postgres

Produces a file/files such as ./models/Users.js which looks like this:

/* jshint indent: 2 */

module.exports = function(sequelize, DataTypes) {
  return sequelize.define('Users', {
    username: {
      type: DataTypes.STRING,
      allowNull: true,
      defaultValue: null
    },
    touchedAt: {
      type: DataTypes.DATE,
      allowNull: true,
      defaultValue: null
    },
    aNumber: {
      type: DataTypes.INTEGER,
      allowNull: true,
      defaultValue: null
    },
    id: {
      type: DataTypes.INTEGER,
      primaryKey: true
    },
    createdAt: {
      type: DataTypes.DATE,
      allowNull: false,
      defaultValue: null
    },
    updatedAt: {
      type: DataTypes.DATE,
      allowNull: false,
      defaultValue: null
    }
  });
};

Which makes it easy for you to simply Sequelize.import it.
