title: Large npm-cache folder on Azure DevOps private build agents
body: <p>The npm cache folders on our private windows Azure DevOps build agents become quite large.</p>
  <p>C:\Users&lt;srviceAccount&gt;\AppData\Roaming\npm-cache
  C:\Windows\ServiceProfiles\NetworkService\AppData\Roaming\npm-cache</p>
  <p>I would like to run a clean task as part of our pipelines, but I'm concerned that this might cause issues for concurrent builds.  Is there a safe way of managing these folders?</p>
