these two tools apparently let you rip borrowed audiobooks from this service named libby. although i haven't tested them. https://github.com/ping/odmpy https://github.com/bookbonobo/libby-download-extension
also, have you checked the index? stuff like this is usually there.
Check out some alternatives:
searXNG - open source & self-hosted meta-search engine (aggregates results from many others, like google, bing, qwant, duckduckgo - configurable which ones.) list of public instances just pick one that's close to you physically and has a good uptime.
duckduckgo - uses bing for most search results, but is way more private
brave search - uses their own index, has a privacy-respecting privacy policy and the results are pretty damn good
from the error it looks like you're importing an es module inside a common.js environment. but as @clif@lemmy.world said, there are several things that could cause this.
