Details

Code

import a from 'binaryen';

console.log(a);

Configuration

module.exports = {
  mode: "none",
  optimization: {
    // when minimize is on, importing binaryen will produce error "'import.meta' cannot be used outside of module code"
    minimize: true,
  },
}

Got

> rspack-repro@1.0.0 build:rspack /Users/kfll/Developer/rspack-repro-binaryen
> rspack -c rspack.config.js

ERROR in × JavaScript parsing error: 'import.meta' cannot be used outside of module code.

Expected

There's type:"module" in binaryen/package.json so it should be considered as module code

More

This only happens when minimize is on

Reproduce Steps

pnpm i
pnpm build:rspack | less

Try to enable module in SWC js minifier plugin.

I've simplified the reproduction.

This problem occurs when importing a "module" package whose main file contains new URL("./", import.meta.url).

Both rspack and webpack will create an asset file xxx.js for the main file itself because of the statement new URL("./", import.meta.url) as documented: https://webpack.js.org/guides/asset-modules/#url-assets

Consider the foo example, the package foo has these two traits:

1. there's new URL("./", import.meta.url) in foo/index.js
2. is a "module" package

When importing foo, both rspack and webpack will

1. bundle content of foo/index.js into the main asset file
2. and also create an asset file xxxx.js whose content is same as foo/index.js

When minimizing the xxxx.js file, depending on the value of package "type"

package type of foo	minimize	rspack	webpack
"module"	ON	❌[1]	✅
"commonjs"	ON	❌[2]	❌[2]
"module"	OFF	✅	✅
"commonjs"	OFF	❌[2]	❌[2]

After dig into it, I just found

• failure [2] is dropped before minimizing which is as expected and has nothing to do with this issue.
• while [1] is dropped on minimizing which causes this issue.
• webpack minifies the file with module: undefined while rspack minifies it with module: false
