IDE for HABPanel Custom Widget Development

Dear Community,

Apologies if this question has been asked and answered. I did review related threads but could not quite get what I was after, hence this post.


  1. Openhab HABPanel UI provide “code”, “Setting” and “Preview”. Am looking for a more robust IDE for the Code section, something with hints, autocomplete, syntax checking - maybe even WYSIWYG. What do you typically use?
  2. Is the above possible using VSCode - to develop standalone, and then simply paste the final code into the UI ?
  3. Chrome periodically hangs when coding widgets - have you experienced ? if yes - whats the root cause and solution ?
