title: Trouble with jsconfig.json in VSCode (dependencies intellisense on import not working)
body: <p>I'm having some trouble finding out the proper way to set the <code>jsconfig.json</code> file in my React / Firebase project.</p>
  
  <p><strong>Root folder structure:</strong></p>
  
  <pre><code>functions/
  node_modules/
  src/
  
  .babelrc
  .firebaserc
  jsconfig.json
  firebase.json
  package.json
  wepack.config.js
  </code></pre>
  
  <p><strong>jsconfig.json</strong></p>
  
  <pre><code>{
    "compilerOptions": {
        "target": "es6"
    },
    "include": [
      "src/**/*"
    ]
  }
  </code></pre>
  
  <p>I'm almost sure that I've been using it like this without any problems before.</p>
  
  <p>I can't tell exactly when it happened, but right now I'm <strong>not getting intellisense for my installed dependencies.</strong></p>

  <p>If I delete <code>jsconfig.json</code> or simply rename to deactivate it, it goes back to normal:</p>

  <p><strong>QUESTION</strong></p>
  
  <p>What am I doing wrong? How is the proper way to set <code>jsconfig.json</code> to get correct intellisense on my current project? Do I have to use it at all? What benefits does it bring to the table?</p>
