title: VS Code auto formatting with prettier
body: <p>Is it possible to auto format on VS Code in directory whose root doesn't have prettier config?</p>
  <pre><code>- root &lt;-  current directory on VS Code
   - app
    - src &lt;- Do i have to be here to run auto formatting??
     - .prettierrc
     - package.json
     - file1
  </code></pre>
  <p>I cannot run prettier in root directory. Do I have to be in the directory which has <code>prettierrc</code>?</p>
