title: Where do i create or generate a Service?
body: <p>I would like to know where should I be generating an <code>angular2 service</code>? The latest documentation of <code>angular2</code> says its okay to generate a service inside the <code>app</code> folder, however, some video tutorials that I'm following has a <code>shared</code> folder pre-generated in which services are created. I could obviously create that folder but I'd like to know what's appropriate and why?</p>
  
  <p><code>app-name/src/app/service-name.service.ts</code> </p>
  
  <p>OR </p>
  
  <p><code>app-name/src/app/shared/service-name.service.ts</code></p>
