How to auto generate migrations with Sequelize CLI from Sequelize models?

Question

I have a set of Sequelize models. I want to use migrations, not DB Sync.

Sequelize CLI seems to be able to do this, according to this article: \"When you use the CLI

While it doesn't auto generate, one way to generate new migrations on a change to a model is: (assuming that you're using the stock sequelize-cli file structure where migrations, and models are on the same level)

1. (Same as Manuel Bieh's suggestion, but using a require instead of an import) In your migration file (if you don't have one, you can generate one by doing "sequelize migration:create") have the following code:

   'use strict';
   var models = require("../models/index.js")
   module.exports = {
     up: function(queryInterface, Sequelize) {
       return queryInterface.createTable(models.User.tableName, 
         models.User.attributes);
     },
     down: function(queryInterface, Sequelize) {
       return queryInterface.dropTable('Users');
     }
   };
   

2. Make a change to the User model.

3. Delete table from database.
4. Undo all migrations: sequelize db:migrate:undo:all
5. Re-migrate to have changes saved in db. sequelize db:migrate
