Sequelize-Auto

Automatically generate models for SequelizeJS via the command line.

Install

npm install -g sequelize-auto

Prerequisites

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

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
  -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:

Example

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:

Testing

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

# for all
npm run test-buster

# mysql only
npm run test-buster-mysql

# postgres only
npm run test-buster-postgres
