Sequelize Model Manager

Sequelize Model Manager provides functionality to handle loading, applying some extensions to model, synchronize models to database, inserting fixtures and so on. The models to manage can be generated using MySQL Workbench Schema Exporter.

The directory layout suggested as follows:

> model                       <- contains model classes
  > addon                     <- contains handler for all models extension
  > data
    > lifecycle.json
    > tostring.json
  > extend                    <- contains model extension
  > extension                 <- contains model attributes extension
  > fixture                   <- contains fixture data
    > Model1.json
  > hook                      <- contains lifecycle handler
    > audit.js
  > Model1.js
  > Model2.js

An example usage of Sequelize Model Manager shown below:

const SequelizeManager = require('@ntlab/sequelize-manager');

const db = new SequelizeManager({
    modeldir: path.join(__dirname, 'model'),
});

(async function run() {
    await db.init({
        dialect: 'sqlite',
        storage: './data/mydb.sqlite'
    });
    await db.connectDatabase();
    await db.syncModels();
    await db.loadFixtures();

    // find a row in database
    const m = await db.Model1.findOne({where: {Id: 990}});
})();
