Fresh dies with "transport was disconnected" on hmr in firefox

[MonstraG]

Steps:

1. install deno via curl -fsSL https://deno.land/install.sh | sh to make sure you get last (my distro has older version)
2. deno clean
3. deno run -Ar jsr:@fresh/init
4. enter twice to not install tailwind or vscode stuff
5. set "nodeModulesDir": "manual" in deno.json, otherwise it might not even run due to error 26 (I think it's VitePress fails to build deno#30424)
6. deno i --allow-scripts (I don't know if I actually need to allow them but to make sure)
7. deno task dev
8. open the page in firefox (http://localhost:5173/) (important!)
9. open assets/styles.css with editor like kate and press Ctrl+S without modifying anything.

server dies with:

Versions:

deno 2.5.3
fresh and all dependencies - whatever would `deno i` give in this template at the time of writing:
fresh itself: 2.1.1
vite: 7.1.9
firefox: 143.0.3
os: EndeavorOS
kernel: 6.16.8-arch3-1 (64-bit)

I'm gonna again stress that you have to open the page in the browser.

[MonstraG]

outfile.mp4

[MonstraG]

It also reproduces in chrome, but you need to ctrl+s like 6 times on average.
Version 141.0.7390.54 (Official Build) (64-bit)

[fry69]

I followed your steps and cannot reproduce this problem on my machine (macOS 15.7.1 aarch64). The HMR works fine and produces this output on the Vite dev server console:

10:37:38 [vite] (client) hmr update /assets/styles.css
GET http://127.0.0.1:5173/
Shared value hello

I noticed this error in your report:

cannot call "fetchModule"

This fetchModule is part of Vite. This part may fail in case of problems with CommonJS (which Fresh has to treat differently) or it seems with paths. At least this is what I can guesswork from looking through a bit code and commits, see e.g. here -> #3204

Since Fresh works perfectly fine on most other environments (CI tests Windows/macOS/Ubuntu Linux), can you please tell us more about your OS and its filesystem and network setup? Is there anything special about EndeavorOS?

---

For anyone reading, here are some general troubleshooting tips to try out. Those likely will not help in this case, but they also do no harm:

Clean the global Deno cache with (was already done in this case):

deno clean

Force reinstall everything bypassing all caches, node_modules folder, deno.lock (can help sometimes):

rm -fR deno.lock node_modules
deno install -r --allow-scripts

See also the troubleshooting guide for other common issues and solutions.

[MonstraG]

I did

deno clean
rm -fR deno.lock node_modules
deno install -r --allow-scripts

did not help me.

EndeavorOS is just Arch with a Calamares installer and KDE by default.

Here is about this system blurb, if useful to anyone:

Operating System: EndeavourOS 
KDE Plasma Version: 6.4.5
KDE Frameworks Version: 6.18.0
Qt Version: 6.9.2
Kernel Version: 6.16.10-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 7600X 6-Core Processor
Memory: 64 GiB of RAM (61,9 GiB usable)
Graphics Processor 1: AMD Radeon RX 9070
Graphics Processor 2: AMD Radeon Graphics
Manufacturer: ASUS

The filesystem is ext4, the default.

Here is the network interfaces blurb:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

I don't think I did anything special to my network setup, is there anything specific I can show you?

FYI: Searching for the other part of your reported error (transport was disconnected) in context of Vite reveals a few open issues for Astro and Svelte, with reports of that sporadically happening, but nothing conclusive or even an obvious fix.

Also, even with hammering Ctrl+S and triggering HMR, I cannot reproduce this problem on my system:

11:24:40 [vite] (client) hmr update /assets/styles.css (x31)
GET http://127.0.0.1:5173/
Shared value hello

I use Firefox stable and have set nodeModulesDir to manual, as instructed.

FYI, here is a possible fix for this race condition, analysis in the PR: #3519

FYI, here is a possible fix for this race condition, analysis in the PR: #3519

I've added vendor: true to deno.json, and manually applied the fix from the PR. On save, it just died in a different place:

This doesn't feel right, especially the vite.config.ts changed

[MonstraG]

Also it creates those:

And if it dies, it doesn't clean it up.
I guess that what makes it think that vite config changed

[fry69]

The only way I can explain this my head is that your system somehow manages to trigger HMR in an extremely fast loop. E.g. one save in your editor somehow results in several (tens or hundreds even?) of HMR triggers. Re-writing a file in chunks might trigger this.

Can you please check that you see the same behavior/crash with other editors or even "manual" HMR triggers from the command line with:

touch assets/styles.css

I generally use WebStorm, and that dies, but
Kate also kills it.
nano is fine.
micro is also fine.
Zed fine
vim dies.

Since HMR get handled by Vite and that also receives those file change events, I think you want to report it there and see if they can add some kind of debounce logic for trigger happy systems/editors? -> https://github.com/vitejs/vite

Yep, got their preact template, reproduced:

6:32:57 PM [vite] vite.config.ts changed, restarting server...
6:32:57 PM [vite] changed tsconfig file detected: /home/arsga/Downloads/vite-project/tsconfig.json - Clearing cache and forcing full-reload to ensure TypeScript is compiled with updated config values.

(first half is Kate, second is micro)

Fresh is a heavy Vite plugin that might surface this problem more than other plugins, those may be able to handle such event storms. There is little Fresh can do except adding everywhere try/catch/ignore blocks and hide this problem.

I'd vote for handling it upstream for now. If the Vite maintainers say that plugins have to deal with such event storms, this can get looked into again here.
