I recently was processing some data using Apps Script, and needed to parse out second-level domain info from a bunch of URLs. This is definitely not the job for regular expressions, but it’s perfect for an npm module, psl, that uses the public suffix list.
But while Apps Script has come a long way, and features lots of ES2015+ goodness nowadays, it’s not possible to pull in arbitrary code from npm and run it directly. To work around this…
Jeff Posnick provides some guidance on how esbuild can be used to bundle npm libraries for use in Google Apps Script. For an alternative approach to this problem you might also want to check Adam Morris’ appscriptsModules.gs solution on GitHub.
