title: Schema and data migrations for node js
body: <p>Is there any tool that works similar to <em>Django South</em>, but for Node? </p>
  
  <p>Now I'm working with Sequelize. If I got it right, Sequelize does not have an option to create migration files based on existing models. 
  So, to create a new model/table, the steps are:</p>
  
  <ul>
  <li>Create model with <code>sequelize model:create &lt;model meta&gt;</code>. </li>
  <li>Edit generated migration file - add actual code for creating tables
  in DB under <code>up</code> section.</li>
  <li>Run migration with <code>sequelize db:migrate</code>.</li>
  </ul>
  
  <p>I'm looking for something that can create migration files based on existing models, manage it similar to what South can do for Django. </p>
  
  <p>Is there any option?</p>
