title: Format *.tsx files on save in VS Code
body: <p>In <code>settings.json</code> it is possible to only format <code>*.ts</code> files with:</p>
  
  <pre><code>"[typescript]": {
      "editor.formatOnSave": true
  }
  </code></pre>
  
  <p>but I can't get it to work for <code>*.tsx</code> files.</p>
