Rspack uses the SwcJsMinimizerRspackPlugin by default to compress code, and you may need to configure the minimizerOptions to set module to true.

Rspack uses the SwcJsMinimizerRspackPlugin by default to compress code, and you may need to configure the minimizerOptions to set module to true.

this is not the best solution since it will cause all js assets are treated module, you can control specific assets by set assetInfo

 compilation.updateAsset(entry, new ConcatSource(
          `export default function(global, globalThis, window, $app_exports$, $app_evaluate$){`,
          source,
          `}`
        ), {
          javascriptModule:true // set this asset as module
  });

but rspack has some bugs about dealing with assetInfo, I'm gonna fix it

should be fixed in #7924
