title: Failed to resolve module specifier "firebase/app"
body: <p>it's my firstime using Firebase and I think that I've followed all step to connect my project to firebase. I tried to run my project with a small <code>js console.log(firebase)</code> When I went to my console I received this error message <code>Failed to resolve module specifier &quot;firebase/app&quot;</code></p>
  <p>I want to mention that I've create a node_module folder and I did npm i firebase.</p>
