title: Connect to a local SQL Server db with sequelize
body: <p>Having completed the SQL Server installer, the given connection string is <code>Server=localhost\MSSQLSERVER01;Database=master;Trusted_Connection=True;</code>, which seems like a strange format, and if I try to connect to the db with sequelize using that connection string:</p>
  
  <pre><code>var sequelize = new Sequelize(process.env.DB_STRING);
  </code></pre>
  
  <p>I get the error:</p>
  
  <blockquote>
    <p>TypeError: Cannot read property 'replace' of null</p>
    
    <p>at new Sequelize
    (C:\Users\George\Source\Repos\TestProj\node_modules\sequelize\lib\sequelize.js:132:40)
