Details

I'm trying to bundle my project using a virtual file system.

Here is my code.

import { rspack } from "@rspack/core";
import { Volume, createFsFromVolume } from "memfs";
  const files = {
    "/index.tsx": `
    import React from 'react';
    import ReactDOM from 'react-dom';
    ReactDOM.render(<div></div> , document.getElementById("root"));`,
  };
  const val = Volume.fromJSON(files);
  const fs = createFsFromVolume(val);
  const compiler = rspack({
    mode: "production",
    entry: "/index.tsx",
    output: {
      filename: "/ouput.js",
    }
  });
  compiler.inputFileSystem = fs;
  compiler.intermediateFileSystem = fs;
  //@ts-ignore
  compiler.outputFileSystem = fs;

  compiler.run((err, result) => {
    const files = val.toJSON();
    console.log(err, result, files);
  });

Here is error message

ERROR in × Failed to resolve /index.tsx in project root

Reproduce Steps

It can be reproduced by running the code I provided.

@Boshen does oxc_resolver supports passing custom filesystem now?

It seems oxc_resolver supports filesystem, but Rspack resolve options doesn't support pass filesystem to oxc_resolver yet

[Boshen]

To support this use case, Rspack needs to implement ResolverGeneric from oxc_resolver with its own implementation of FileSystem, and expose the relevant APIs to the JS side.

The last time I tried to work with inputFileSystem, I realized that rspack only use .purge method of it.

therefore I think rspack hasn't been ready for inputFileSystem. pls correct me if i got the thing wrong.

since inputFileSystem is a public API, other Rspack|Webpck plugin may use other method in it.

i mean that rspack doesn't utilize inputFileSystem for reading file system.

Previously, i used to create memfs as inputFileSystem and outputFileSystem for unit testing purposes. This allowed me to avoid generating numerous fixture files in my repository or pay effort at cleaning up test artifacts after testing

However, when I attempted to do the same with rspack, I noticed that the outputFileSystem worked as expected while the inputFileSystem didn't

[hardfist]

because Rspack read outputFilesystem and not read inputFilesystem in Rust side yet, see https://github.com/web-infra-dev/rspack/blob/main/crates/node_binding/src/lib.rs#L68

i see - i believe this issue is also this thing.

@xc2 do you want to give it a try to implement this feature?

hard to promise as i'm quite new to rust. previous i had a hard time to impl module.noParse, still being blocked by a runtime panic to do with the js function call in rust.

i will still give it a try but it is supposed to be long.

It's not an urgent feature, so take your time, and if you met problems when contributing to Rspack, feel free to ping us

Bump. I have a feeling this might be related to me not being able to use the webpack-virtual-modules plugin with Rspack.

I've since found the rspack virtual module plugin.
