title: How to setup express and node into an existing front-end only Angular 2 project?
body: <p>I have a current front-end only Angular 2 application using the Angular-CLI and NPM. I want visitors to be able to send me emails through the contact form.</p>
  
  <p>For this I obviously need a back-end, express and node, in which I have no experience in using.</p>
  
  <p>I need to intergrate express and node into my app but I dont know how to do this correctly.</p>
  
  <p>I have found <a href="https://stackoverflow.com/questions/41211473/how-to-add-node-to-an-existing-angular-2-typescript-asp-net-core-project">THIS</a> similar question on SO but its not relevant to my situation.</p>
  
  <p>Other tutorials only show how to scaffold a MEAN stack app not intergrate the backend after the front end has been built.</p>
  
  <p><strong>What I would like to know</strong>:</p>
  
  <ul>
  <li>How do I set up my Angular 2 App to use express and node for the back end?</li>
  <li>What are the relevant files I need?</li>
  <li>Can I do this by using the Angular-CLI?</li>
  </ul>
