Describe the bug

Client is updated with HMR and subsequent reloads but server is not. Causing hydration error.

It might be related to the issue https://github.com/nuxt/framework/issues/2047 since now client HMR on Linux works and Server not (in current nuxt, it is otherwise). But also trying CHOKIDAR_USEPOLLING=1 I still have same issues.

I can also reproduce it on MacOS (testing on 13.1). Client HMR stops working when viteNode flag is set resulting in hydration mismatch:

@antfu Can you please check this? I can confirm on multiple mac versions it is also broken...

Do we have a watcher still with vite-node?

[antfu]

Yes, we have Vite's watcher to invalidate the modules. I will investigate

[antfu]

I can confirm this bug in the edge build, but not in our development playground.

Is it still not working on Linux/Windows?

[pi0]

@antfu Yes i could constantly reproduce on Windows (Windows 11 on PC + Parallers on M2 arm64) and Randomly on Linux (WSL). Will share a screen cast of issue. It is not directly fault of vite-node BTW but when we enable vite-node, since server watcher happens first, client watcher gets broken eventually.

I can no longer reproduce it on rc.8. Seems an underlying library fixed the root cause!
