try opening that cdn link you sent in a browser. it'll open a directory listing for the package. you can see some examples of what urls to use on the main jsdelivr page.
I imagine the url you want is probably something like https://cdn.jsdelivr.net/npm/[email protected]/dist/index.js (note the extra path on the end and also a specific pinned version instead of latest so new versions don't break things)
i already use what urls!
Maybe include your "add it" and "the library turned into undefined" code as a minimum example?
So people can actually check your assumptions and actions and match it against the lib.
That js file certainly doesn't look like a normal module to me that I would expect when importing a module.
But I'm not too familiar with the JS ecosystem to the point where I know what that dynamic Object.defineProperty(exports, "__esModule" magic does or how it's supposed to be used.
But I can see why the import would result in undefined.
With my first search of LemmyHttp I land on https://join-lemmy.org/api/classes/LemmyHttp.html, which says Defined in src/http.ts:153. Have you considered importing http.js? Looking at the http.js on the CDN I can at least see the LemmyHttp class type you seem to try to import.
exports not defined...
given how dynamic creation it looks maybe it has to be executed/included rather than imported and then the class is available?
With all that magic, and looking at https://join-lemmy.org/api/index.html if you're not using pnpm I would give up on that lib.
hmmm... okay!
