title: .gql or .graphql file types with Node
body: <p>I'm using Apollo's <code>graphql-server-express</code> with Node and I would like to turn my "typedef" schema definition files into <code>.graphql or .gql</code> files for clarity and syntax highlighting.</p>
  
  <p>What is the best way to do this? I cannot find any good resources online beyond Babel(?) which seems to be the only choice.</p>
  
  <p>Thanks so much for the help!</p>
