Automatically generate models for SequelizeJS via the command line.


npm install -g sequelize-auto


You will need to install the correct dialect binding globally before using sequelize-auto.

Example for MySQL/MariaDB

npm install -g mysql

Example for Postgres

npm install -g pg pg-hstore

Example for Sqlite3

npm install -g sqlite

Example for MSSQL

npm install -g tedious


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

  -h, --host        IP/Hostname for the database.   [required]
  -d, --database    Database name.                  [required]
  -u, --user        Username for database.
  -x, --pass        Password for database.
  -p, --port        Port number for database.
  -c, --config      JSON file for Sequelize's constructor "options" flag object as defined here: https://sequelize.readthedocs.org/en/latest/api/sequelize/
  -o, --output      What directory to place the models.
  -e, --dialect     The dialect/engine that you're using: postgres, mysql, sqlite
  -a, --additional  Path to a json file containing model definitions (for all tables) which are to be defined within a model's configuration parameter. For more info: https://sequelize.readthedocs.org/en/latest/docs/models-definition/#configuration
  -t, --tables      Comma-separated names of tables to import
  -C, --camel       Use camel case to name models and fields


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

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

/* jshint indent: 2 */

module.exports = function(sequelize, DataTypes) {
  return sequelize.define('Users', {
    id: {
      type: DataTypes.INTEGER(11),
      allowNull: false,
      primaryKey: true,
      autoIncrement: true
    username: {
      type: DataTypes.STRING,
      allowNull: true
    touchedAt: {
      type: DataTypes.DATE,
      allowNull: true
    aNumber: {
      type: DataTypes.INTEGER(11),
      allowNull: true
    bNumber: {
      type: DataTypes.INTEGER(11),
      allowNull: true
    validateTest: {
      type: DataTypes.INTEGER(11),
      allowNull: true
    validateCustom: {
      type: DataTypes.STRING,
      allowNull: false
    dateAllowNullTrue: {
      type: DataTypes.DATE,
      allowNull: true
    defaultValueBoolean: {
      type: DataTypes.BOOLEAN,
      allowNull: true,
      defaultValue: '1'
    createdAt: {
      type: DataTypes.DATE,
      allowNull: false
    updatedAt: {
      type: DataTypes.DATE,
      allowNull: false
  }, {
    tableName: 'Users',
    freezeTableName: true

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

Configuration options

For the -c, --config option the following JSON/configuration parameters are defined by Sequelize's options flag within the constructor. For more info:


Programmatic API

var SequelizeAuto = require('sequelize-auto')
var auto = new SequelizeAuto('database', 'user', 'pass');

auto.run(function (err) {
  if (err) throw err;

  console.log(auto.tables); // table list
  console.log(auto.foreignKeys); // foreign key list

With options: 
var auto = new SequelizeAuto('database', 'user', 'pass', {
    host: 'localhost',
    dialect: 'mysql'|'mariadb'|'sqlite'|'postgres'|'mssql',
    port: 'port',
    additional: {
        timestamps: false
    tables: ['table1', 'table2', 'table3']


You must setup a database called sequelize_auto_test first, edit the test/config.js file accordingly, and then enter in any of the following:

# for all
npm run test

# mysql only
npm run test-mysql

# postgres only
npm run test-postgres

# postgres native only
npm run test-postgres-native

# sqlite only
npm run test-sqlite
