Here's a thread to catalog any minor DOM updates we do throughout 2023 just to give folks in the user community a bit of a heads up and an official source of documentation around any DOM changes.

fellow hackers

This is a "best effort" source and we will try to note any changes here that will impact user scripts as best we can. Unfortunately, we can't promise that we'll catch everything that might break your scripts.

If you're a script maintainer or heavy user of scripts, we encourage you follow the answer, so you get notifications of changes.

    As one of the userscript developers I'd like to say - thank you for making good on the promise of making the lives of script devs easier! Having the changes to the DOM catalogued is a very nice step up from us having to figure out what changed when scripts suddenly stop working as intended. Commented Feb 4, 2023 at 7:54

    This is amazing outreach; thank you! Can this also be updated when Stacks.css changes are made? E.g. when a selector is replaced with a more specific one?

    I wish I found this earlier. This truly is incredible outreach. I've never seen any other company do this. Thank you. Commented Jul 26, 2023 at 19:08

DOM Changelog

Date Change
2023‑01‑09 Update .comment-up-undo to .js-comment-up-undo to be inline with our js-* naming standard
2023-02-03 Update .comment-up to .js-comment-up to be inline with our js-* naming standard
2023-02-09 Removed Svg.* icons from global window object.

If you need icons, please import @stackoverflow/stacks-icons, which can also be done via unkpg.

Then Svg.EyeStacksIcons.Icons.IconEye
/ Future tag updates might use s-tag over post-tag to unify tag styling. They would also add a js-hoverable-post-tag to the majority of changes to be inline with our js-* naming standard.

User scripts that deal with tags should try to handle both cases in order to be future-proof.

    Out of curiosity, why would css classes start with js-? Commented Feb 3, 2023 at 20:32

    We use that to distinguish that the only layer that should care about this class is JS to add event listeners / dom manipulation or something. This makes it easier to reason about changing the styles of something like .comment-active, knowing changing the class won't break any JavaScript.

    Just a word of advice, I'd highly recommend publishing advance notice when doing so, which can most easily be done when pushing the change into source control before the build deploys to the public sites, but preferably a few days' notice. This way, script authors can update their scripts so there's no downtime for script users. Some user scripts are important for content curation so having them be broken for 6-8 days while waiting for the script author to update it can be annoying. (A similar thing is already done today for translations.) Commented Feb 3, 2023 at 20:38

    I share the sentiment and goal @SonictheAnonymousHedgehog, and hopefully we can provide some degree of lead time, but PRs sitting in the queue for 6-8 days is gonna really hurt in a 2 wk sprint cycle. Most of these are updated under the "clean beach principle" while working on a related ticket.

  • @StephenOstermiller to add to what's been said above, it's a well-known naming convention for CSS classes that are used by JS logic to match elements rather than to style things. Commented Feb 4, 2023 at 7:51

    It seems that somple properties of the global Svg object are now not exposed. Is this intentional? Commented Feb 9, 2023 at 18:05

    @double-beep, we recently did swap out our svg icons to point to StackExchange/Stacks-Icons, but I'm not sure that impacted the windows.Svg object got touched (It's possible though). We still have some icons explicitly wrapped as properties. Do you know what you're missing?

    @KyleMit the list used to be much longer (200+ icons). For example. Svg.Gear() and Svg.Eye() are missing. Commented Feb 9, 2023 at 19:02

    @double-beep, ah, yeah, I see the PR - one previous to the one I was looking at. Looking into it. We refactored it to an imported method because our long term goal in is to not rely on global scope in scripts. But also want to see if we can produce an artifact on the global scope.

    Hey @double-beep, had a quick discussion internally about this and we're not quite in easy "rollback" territory since this was a intentional move to refactor to an external icon package in order to not maintain the property list in two places - which always required two separate PRs to add icons. Added to the changelog with a workaround to use unkpg to get icons - which is the same package we're building from internally, so guaranteed to be the same. Thanks for pointing out and hopefully this helps

    @gcasar the removed change, that was already planned, is officially aborted, or postponed to unknown time? (Also, in my opinion better keep it written here and add comment saying it's aborted or postponed, no?) Commented Dec 7, 2023 at 10:54

    @ShadowWizardIsSadAndAngry The original entry was related to our color change efforts (related post) but that was achieved without it. I've gone and reworded my original edit to hopefully keep it in line with the spirit of the post - to give folks a heads up that post-tags are special and have a higher likelihood to break user scripts in the future, even if we cannot provide a timeline around it. Realistically, this might still come up, but in smaller chunks.
