title: Cannot use es6 import and export with sequelize
body: <p>I am using convictjs to manage the configuration files for my nodejs application.  The file that has the configuration schema is called "config.js" and it is in the "config" folder.  </p>
  
  <p>I am using es6 import and export statements </p>
  
  <pre><code>import convict from "convict";
  import dotenv from "dotenv";
  import configDev from "./config.dev";
  import configProd from "./config.prod";
  import configStage from "./config.stage";
  .
  .
  .
  export default config.getProperties();
  </code></pre>
  
  <p>These configuration files contain database credentials and other necessary database information, which I use in the "index.js" for the sequelize models.  </p>
  
  <p>Note:  Early on in the development process we tried using es6 with sequelize ran into other problems so we opted to using es5 for models, migrations and seeds.</p>
  
  <p>Currently whenever I try to execute migrations, seuqlize throws an error as shown below</p>
  
  <pre><code>ERROR: Error reading "config\config.js". Error: SyntaxError: Unexpected token 
  import
  </code></pre>
  
  <p>Babel is setup properly, I can transpile and run the application  without any issues except for database migrations.  Any help to resolve this issue is much appreciated.</p>
