title: How to make CircleCI call npm install on two places?
body: <p>I have just started working with CircleCI so I don't know whether this is too obvious.</p>
  
  <p>Problem is, that I have react website and react native project in one folder. React website uses <code>project/package.json</code> and <code>project/node_modules</code>, while React Native project uses <code>project/nativeApp/package.json</code> and <code>project/nativeApp/node_modules</code>. </p>
  
  <p>To make both run and test correctly, I need to <code>npm install</code> in both locations. How do I tell CircleCI to do that?</p>
