title: Sequelize - load new model without restarting server
body: <p>Sequelize uses the models/index.js file to load all the models so they can be used in the queries. When you add a new migration and model, usually the server needs to be restarted in order to be able to use that new model in a query.</p>
  <p>How can I read in all models or a specific model to use in a query without restarting the whole node server?</p>
