  </code></pre>
  
  <p>My problem is that I need to embed all these dependencies (and their dependencies) in my package node_modules folder.</p>
  
  <p>So my package consists now of more than 5000 files and more than 300 MB.</p>
  
  <p>Is there a way to not include the node_modules folder in the package but tell to vscode to install them when installing my extension ?</p>
  
  <p>Thanks :)</p>
