Parcel won't stop rebuilding in dev mode

🐛 bug report

Running parcel in “dev mode” on OS X just constantly rebuilds which triggers reloads making it impossible to work with 😦

🤔 Expected Behavior

It should only rebuild and reload when I save a file.

😯 Current Behavior

Constantly rebuilding and causing refreshing. The gif below you can see. I’m doing absolutely nothing but sitting and watching my terminal.

💁 Possible Solution

Maybe not a solution per se but it’d be nice to get some info on what is causing this refresh. Something is triggering a “change” event, but what?

🔦 Context

Just a brain dump but I’m working in IntelliJ. I tried IntelliJ’s terminal and iTerm. I’ve tried deleting node_modules, dist, .cache, and package-lock. I’ve reinstalled npm modules multiple times.

💻 Code Sample

I can’t publicly share the code but it’s a pretty simple React app that uses Firebase and Firestore.

🌍 Your Environment

Software	Version(s)
Parcel	1.12.3
Node	10.16.0
npm/Yarn	6.9.0
Operating System	Mac OS 10.14.1 (18B75)

I create a new example from scratch on my system and now works perfectly.

I have been working fine with no problems for a while. Sometimes, when write an import to a .js file and save, infinite looping has started.

• If I break (CTLR-C) and restart Parcel, it continues loop.
• If I delete the .parcel-cache folder and restart Parcel, works correctly again.

Thank you! Completely the issue I was dealing with. Not sure what was in the cache triggering the change event, but it’s simple enough to let parcel just rebuild.
