lobste.rs has a js-error: here is a mitigation

5 points by refp 11 hours ago on lobsters | 16 comments

The previous tampermonkey script is sadly unstable, use the below:

Install ViolentMonkey or TamperMonkey
Create a new script (see next section)
Reload the page.

Note: tampermonkey requires "enable user scripts" in your browser's extension settings, ViolentMonkey has no such requirement.

This works consistently for me now.

// ==UserScript==
// @name         lobste.rs qS/qSA repair
// @match        https://lobste.rs/*
// @run-at       document-end
// @grant        none
// ==/UserScript==

let nonce = null;
for (const s of document.scripts) if (s.nonce) { nonce = s.nonce; break; }
if (!nonce) throw new Error('no nonce found');

const el = document.createElement('script');
el.nonce = nonce;
el.type = 'module';
el.textContent = `
window.qS = (a, b) => b === undefined ? document.querySelector(a) : a.querySelector(b);
window.qSA = (a, b) => b === undefined ? [...document.querySelectorAll(a)] : [...a.querySelectorAll(b)];

const map = JSON.parse(document.querySelector('script[type="importmap"]').textContent);
const mod = await import(map.imports.user + '?retry=' + Date.now());
window._LobstersFunction = mod._LobstersFunction;
document.dispatchEvent(new Event('DOMContentLoaded'));
`;
document.documentElement.appendChild(el);
el.remove();

@lalitm see above, this should work (TM)

It works! Thanks so much!

please upvote the relevant comment so that it drifts to the top, I cannot edit the original posting anymore.

Sorry about this, I'm working on it now. More technical details here.

The originally posted snippet is faulty, please see this:

Notes

as a community there are probably easier mitigations we could come up with together, but the TamperMonkey approach works fine.
make sure you enable "Allow User scripts" under the extension settings if you like me installed it only for this).

I assume this has been reported to the public repo?

[OP] refp | 11 hours ago

There is the following issue:

https://github.com/lobsters/lobsters/issues/2187

There has been heavy activity regarding this in ´#lobsters` (IRC), so at least it is known/discussed there.

Do you mind trying the approach and perhaps upvote this story as a sign of success?

I hope it is as easy for others to fix as it was for me, but with that I don't really know what is considered "easy" given that I assume most do not have web dev experience.

I just tried the TamperMonkey approach and sadly does not seem to have done anything: I'm still seeing the error in console and upvoting doesn't work either.

[OP] refp | 10 hours ago

Ok, so there is a race between the tamperscript being invoked vs the lobster's javascritp is executing. If you have the dev-console open the load slows down enough to always inject our script, so.. browsing with dev-tools open seems to make it more stable!

On a M4 Macbook Air, sadly even having Devtools doesn't seem to slow things down enough!

[OP] refp | 11 hours ago

someone just upvoted this story so it seems to work for someone else but me.
Did you enable "Allow user scripts" in the extension, as well as reloading the page?

I have never written anything for tampermonkey before so there might something which isn't ideal in the proposed snippet, but it seems to be working for me.

Edit: Seems to go back to b0rked on some page transitions, working on a fix!

wfm using violentmonkey on vivaldi, if that helps.
