Has anyone tried running Auto-Reload feature with HTMX or staticResources? For some reason it is not working for me. It catches the changes, but then the web-app is not working, even though Java process is still running.

I'd need to debug it albeit more to find the culprit, but I wonder if someone had this issue? With "normal" Ktor server it is working fine. Only with HTMX setup it isn't

Thank you, will follow the issue!

Which version of Ktor do you use?

[skominas.ainis]

3.2.3

[Aleksei Tirman [JB]]

Then it shouldn't work at all because of the regression.

The issue happens in this repo too: https://github.com/anderssv/kotlin-htmx

Although, I don't see any errors. As I said, didn't debug more, but something might be off

Just it is not auto-reloading. With non-staticResource projects auto-reloading works fine

I had 2 issues, as reported in the issue:
• embeddedServer -> autoreloading not working at all, EngineMain works fine
• staticResources not working at all, after a reload they are not found
So, with non-static Resources it can be true that it does work, as long as you use EngineMain

Usually reload for me doesn't rebind to the address 🫠

[skominas.ainis]

I wonder if it would be feasible to adapt same solution from compose-hot-reload with DCEVM to Ktor JVM? Sadly, it would be only for JVM, but I believe Ktor-Server is mostly ran in JVM?

Checked Ktor code and some logic for Auto-Reloading dates back to 2015

[Aleksei Tirman [JB]]

@skominas.ainis, we already have plans for this.

[skominas.ainis]

Oh, that's very nice. Good to see that!

[skominas.ainis]

One more thing regarding staticResources is that if I add a new file (e.g. image) or edit an existing *.css file for example I need to do a full rebuild to have it reflect the change.

Maybe I am doing something wrong?

[Aleksei Tirman [JB]]

The auto-reloading is expected to work if you edit an existing resource.

[skominas.ainis]

Okay. I might be doing something wrong, but neither auto-reload or running a new Ktor instance work. Only full rebuild reflects new changes.

I'll try to come up with a reproducible build if possible

[Aleksei Tirman [JB]]

Can you try version 3.1.3 of Ktor?

[skominas.ainis]

Not really, as I am using HTMX which was not available at 3.1.3

EDIT: I can, one sec, will see if it works

[Aleksei Tirman [JB]]

If you use Ktor 3.2.0 or above, then it's the regression filed in KTOR-8821.
