writeToDisk don't copy files in public directory to disk, is this expected?

Reproduce link

Reproduce Steps

open codesandbox link and run pnpm run dev

[chenjiahan]

Yes, this is expected, Rsbuild only copy files from the public dir to the dist dir on the production build.

[wood3n]

Could this support in the development environment? Or I can only use output.copy to do this?

[chenjiahan]

Yeah you can use output.copy to do this.

@9aoy Should we copy the public dir during development build if writeToDisk is true?

[9aoy]

output.copy and server.publicDir can achieve similar functions, but they are implemented in different ways.

From the perspective of publicDir feature implementation, it is not necessary to write to the disk during development build . I'm a little curious, what circumstances do you need to rely on copying files to disk? @wood3n

[wood3n]

@9aoy 😄 when develop chrome extension, it needs a manifest.json, so I put it in public folder.

[chenjiahan]

Okay, so it is expected that public dir is not copied during dev build, I will document this.
