Inconsistent assetsBuildDirectory path in "build/server/assets/server-build-[hash].js" while nested building in Windows

[adelriosantiago]

Describe the bug

The assetsBuildDirectory path inside "build/server/assets/server-build-[hash].js" is not consistent with other path formats in the same file when building in Windows.

In Windows, when using buildDirectory: 'build/subdir' and buildDirectory: 'build\\subdir' will both generate a build at "build/server/assets/server-build-[hash].js" that contains:

//...
const mode = "pre-prod";
const assetsBuildDirectory = "artifacts\\test\\client";
const basename = "/";
//...

All other folder separators are correct, except assetsBuildDirectory . This breaks builds done in Windows that are then transferred to a Linux machine for deploy in Azure.

Reproduction

Can't reproduce in view.new unfortunately

Steps to reproduce

-Grab a project with a vite.config.js.
-Build in Windows with buildDirectory: 'build/subdir' then with buildDirectory: 'build\\subdir'
-Both "build/server/assets/server-build-[hash].js" builds generate the same "assetsBuildDirectory" which is correct in Windows, but not in Linux.
-I would expect: The "assetsBuildDirectory" to have "/".

I guess assetsBuildDirectory is an option in remix and not Vite. Please make the issue in remix-run/remix.
