How can I get the original line number and symbol from a sourcemap

Question

I'm logging javascript errors from my site, but the files are minimized so I don't get meaningful line numbers. I do have source maps, however.

Is there a service, script, npm module, or anything that can help me "translate" the line numbers from the minified versions into something useful?

I have found the answer using this npm module:
