Unusual CPU usage while developing on Next.js

[asamolion]

Hi there,

I’m using Next.js to develop a front-end of an app. However, whenever I run the next.js dev server and begin developing, Sublime Text starts 1 or 2 extra “crawl” processes and uses upto 12% of my CPU. This causes my CPU to reach 75+ degrees instead of the normal 40.

Any idea what could be causing such high usage?

My guess it that the crawl process should be a one time thing. It should not continuously happen in the background.

Probably because the server is touching files that are in your project, ST thinks they’ve been modified and is reindexing them.

Is there a way I can figure out which files sublime detects as changing everytime?

On linux you can use inotifywait -mr . from the project folder to find out which files are being changed.

Thanks to @bschaaf’s advice, I was able to find out the culprit files and fix the issue using Sublime’s index_exclude_patterns setting.
