title: Concurrently JS application pipeline install and build hangs (Express js for server, Create-React-App for Client)
body: <p><strong>Problem</strong>: I have a project with a server (Express Server that handles file uploading and deleting) and client (Front End Create-React-App). The project structure looks like follows:</p>
  <p><a href="https://i.stack.imgur.com/qM6kL.png" rel="nofollow noreferrer">Root Folder With Server</a></p>
  <p><a href="https://i.stack.imgur.com/KO3aI.png" rel="nofollow noreferrer">Client Folder</a></p>
  <p>Each folder has it's own package.json. <a href="https://i.stack.imgur.com/tBlaB.png" rel="nofollow noreferrer">Server Package.json</a>. <a href="https://i.stack.imgur.com/zKdes.png" rel="nofollow noreferrer">Client package.json</a></p>
  <p>I'm trying to build and deploy onto azure however <a href="https://i.stack.imgur.com/gQH0k.png" rel="nofollow noreferrer">the pipeline hangs on &quot;npm install and build&quot;</a>.</p>
  <p>It seems like the build succeeds but this phase just hangs. Here is my <a href="https://i.stack.imgur.com/pvAUL.png" rel="nofollow noreferrer">server.js</a> (the  routes are not included) file and <a href="https://i.stack.imgur.com/N9kHc.png" rel="nofollow noreferrer">yaml file</a> just in case.</p>
  <p>I'd appreciate any kind of help. Thank you!</p>
