Getting favicons

[cf]

I’ve been using a form for storing bookmarks but text-only makes it hard to browse the list. Here’s a script that automatically fetches the favicon for each URL in a form. Obviously you would need to update with your own ids.

// https://stackoverflow.com/a/54947757/952123
const getHostname = (url) => {
  // run against regex
  const matches = url.match(/^https?\:\/\/([^\/?#]+)(?:[\/?#]|$)/i);
  // extract hostname (will be null if no match is found)
  return matches && matches[1];
}

function favIconURL(domain) {
	return https://www.google.com/s2/favicons?domain=${domain};
}

function getFavIconURL(url) {
	return favIconURL(getHostname(url));
}

function getFavicon(r) {
	const url = r.getFieldValue('fld-026ad10a88d74569a6d37b19aa7b77a6');
	console.log(getFavIconURL(url));
	r.addPhotoFromUrlToField(getFavIconURL(url), 'fld-42eeb21b65464cb39aa966772620acba', { "filename": "favicon", "prevent_duplicates": true})	
}

function getIfEmpty(r) {
	const thumbnail = r.getFieldValue('fld-42eeb21b65464cb39aa966772620acba');
	if (thumbnail.length) return;
	return getFavicon(r);
}

form.getRecords().forEach(getIfEmpty);
form.saveAllChanges();
