title: What is the proper way to start multiple local node.js servers?
body: <p>I'm creating an example project for an open source framework. For my demo to run, some of it's dependencies must be running local servers on other ports.</p>
  
  <p>I'd rather just provide them a single command to run instead of telling them to open multiple terminals and run multiple commands in each.</p>
  
  <p>What is the best/most proper/most elegant way to go about this?</p>
