title: How to create an npm script
body: <p>I have two folders: client and server. When I run the server, I want to create a distribution command with the npm run build command in the client folder.</p>
  
  <p>For example, what I want to do is to run npm start in the server folder and then run npm run build in the client folder.</p>
  
  <p>Is this possible?</p>
