title: Install NPM dependancies for sub package which is nested within my main project?
body: <p>I have a main package.json for my project. I also have a component within my project which I'm publishing to NPM, so that requires its own package.json. </p>
  
  <pre><code>package.json
  index.html
  -folder
  --component-folder
  ---package.json
  </code></pre>
  
  <p>Both package.json files define dependancies. At the moment I have to run <code>npm install</code> from both my project root and from component-folder. Is there a way of making it install dependancies for both when its only run from the project root? </p>
