Timed out waiting for dist/*.js after 30 seconds

[chuntley]

On OSX, after running npm run watch I periodically get the error:

Timed out waiting for dist/*.js after 30 seconds
npm run watch-server-start exited with code null
Sending SIGTERM to other processes..

The server never starts because of this, so I end up having to rerun the watch command. If I run watch, then change a couple of files, sometimes it will catch the change and run the server. Any ideas on what could be causing this?

Every now and again I get issues when running npm run watch. To resolve this I normally just remove all the hot update files (*.js, *.map & *.json) in that directory and it resolves the issues.

Hi there!
I experienced the same problem! In my case, I solved increasing the just-wait time in package.json.

"watch-server-start": "node node_modules/just-wait -t 50000 --pattern \"dist/*.js\" && npm run start".
