Constantly loosing HMR connection

[ckissi]

If I close npm run dev command and rerun it the problem persists.
It's also browser-independent. Tried Chrome, FF, Safari with the same result.

Parcel: 2.0.0-nightly.489
Node: 14.15.4
npm 6.14.4
OS: MacOS 11.2.3

is there any way you can provide a minimal reproduction case for this? Not sure what causes this without any additional steps to reproduce this.

Unfortunately, I have no idea. It works and then it stops working for some reason. Actually, nothing helps then. I mean if I restart the process it's the same. After I restart my iMac it works for a few minutes and then stops again.

I'm having the same thing happening to me on Ubuntu after upgrading to 2.0.0-beta.2 from v1.

#5660 seems to be related

I get the same error. When I change something in index.html and save, nothing changes and the console shows console was cleared.

If I then save the index.js file, I get the connection to the HMR was lost, but the page does refresh with the html edits.

I was able to resolve the issue by switching to webpack

Yeah, I am not sure if I would consider that a solution. I do not need webpack for most of my projects, and Parcel is just to easy and quick to setup with tailwind, I would prefer to be able to use it properly.

I agree. I use tailwind as well and was really enjoying the simple setup of parcel, but switching to v2 was a nightmare. I had build issue pop up in CI/CD and dev server issue with HMR not working as well as other project specific issues. I spent longer trying to fix parcel and browse the issue threads with no support than it took me to fully convert my app to webpack. Its not a perfect solution, but when there is a lack of support on major issues I can't just wait around for them to be fixed with the project I'm working on. I'd be happy to revisit parcel when all of these issues are fixed as I thought it was pretty great otherwise.

If you want to consider webpack, let me know and I can share my config with you for tailwind.

Yeah, I will take you up on that! Tried a few variants, and to make one myself, but I just cant get it to work right.

I ended up transferring the project to snowpack for now.

There's not much we can do without more details:

I know this issue is closed, but could the devs also consider making the "HMR connexion lost" a bit more verbose so that we know what’s going wrong?
