title: firebase deploy gives welcome screen
body: <p>I am new to using Firebase and after I developed a react project, I tried to deploy my application with firebase but it doesn't work. Firebase is already connected to my app for the database. 
  This is what I did to deploy it:</p>
  
  <p><code>firebase login</code></p>
  
  <p><code>firebase init</code> (I tried all possibilities, I always chose HOSTING
   and then as a public directory I tried with public / build / dist )</p>
  
  <pre><code>firebase deploy
  </code></pre>
  
  <p>but still, it gave me 2 links as following :
  <a href="https://i.stack.imgur.com/CkRAo.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CkRAo.jpg" alt="enter image description here"></a></p>
  
  <p>and when I click to the Hosting like, this is what it shows (not the app) :</p>
  
  <p><a href="https://i.stack.imgur.com/zD6bq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zD6bq.png" alt="enter image description here"></a></p>
  
  <p>Also, this is what my firebase.json file looks like (when I use build as a public directory)</p>
  
  <pre><code>{
    "hosting": {
      "public": "build",
      "ignore": [
        "firebase.json",
        "**/.*",
        "**/node_modules/**"
      ]
    }
  }
  </code></pre>
  
  <p>maybe I do have to do some changes in this file ?</p>
  
  <p>I also tried firebase serve to test it locally, and it shows me the same page (welcome page).
  But when I try my app with ng serve, it works.</p>
  
  <p>Could you help me please ? Thank you ! </p>
