Hey Community,
I’m comparing Sentry and Monti at the moment for Client Logging and I want to add sourcemapping for better error logs. It seems that the standart-minifier package of meteor does not provide sourcemapping and the docs of monti suggesting zodern-standart-minifier which got no updates now for a while. Which minifier do you use to provide sourcemapping?

zodern:standard-minifier-js is still maintained. There hasn’t been much need to update it.

Thanks for your response. I’m testing the zodern-standart-minifier together now with hide-production-sourcemaps. So far my builds fail with:
/build/.meteor/packages/zodern_standard-minifier-js/.5.3.1.nka808eq0i++os+web.browser+web.browser.legacy+web.cordova/plugin.fastMinifier.os/npm/node_modules/meteor/fastMinifier/node_modules/meteor-package-install-swc/.swc/node_modules/@swc/core/index.js:110:29:
#16 202.8 x 'import.meta' cannot be used outside of module code.
Am I missing some config which is now needed?

I get a build error when upgrading to meteor 3.0.3 with minifier version 5.3.1. … It did not happen with meteor 2.10.0 on the same version and there is also no error when using the [default minifier](https://packosphere.com/meteor/standard-minifier-js) and meteor 3.0.3.

The reason seems to be a reference to `import.meta` in the package [ffmpeg](https://www.npmjs.com/package/@ffmpeg/ffmpeg), which is [dynamically imported](https://github.com/samhirtarif/react-audio-recorder/blob/1c5298cf29aaf9cd6415180a37ee14ca36ccba70/src/components/AudioRecordingComponent.tsx#L72) by the package [react-audio-voice-recorder](https://www.npmjs.com/package/react-audio-voice-recorder)
Its reproducible in a base meteor react app, with just react-audio-voice-recorder installed and imported. You mentioned on a [meteor ticket](https://github.com/meteor/meteor/issues/12324) that "Meteor has never supported import.meta", but since it is working in meteor 2.10 and also in 3.0.3 with the standard minifier, I thought it might be fixable in this case.
Make sure your project is set up to use ES modules correctly, as that might resolve the issue.
You might also want to check your Meteor and package versions to ensure compatibility. If you haven’t already, consider looking at the minifier’s GitHub issues page for any related discussions or workarounds. It could be helpful to see if others have faced similar challenges.
