Description
When we write plugins or build tools using Vite's JS API, it would be nice to write in-memory e2e tests to check what is generated from a certain input. Now the Vite codebase is hardwired with the node:fs module. Therefore, we cannot replace it with an in-memory implementation like memfs to run our tools with an in-memory representation of files, then verify the results.
Suggested solution
Rollup just introduced this feature in: rollup@4.43.0
The corresponding issue and PR:
rollup/rollup#5880
rollup/rollup#5944
The solution could be that build function could also take an fs option, similarly to rollup:
https://rollupjs.org/configuration-options/#fs
Also, rollup is providing the fs option to the plugins in the context. It would be nice to have it in Vite as well.
