Why is GitHub UI getting slower?

Also as a part of their bullshit React rewrite in addition to making everything much much slower they also managed to break basic functionality like the back and forth buttons on Safari that only got fixed quite recently but for a good 9-12 month period it was impossible to use on iOS.

Genuinely whoever was a part of pushing this rewrite should have been fired.

It WAS that (and web components) but the new fucked up version we are talking about here is React which is very literally one of the main sources of the problem.

Everything has been getting worse since the React rewrite(s). Everything is just so much more slower and janky. And things like the "back button" keep acting weird (I reported this several times, after a long delay they fixed it several times, and it just keeps breaking a few weeks later – I've given up).

Some of the design decisions are also just baffling, like having "New Issue" in a small modal instead of just a full-screen page (only if you have templates set for some reason). Having less than half the screen being used is not helpful, and only going to reduce the quality of reported issues because it's just shit UX. Baffling. I genuinely wonder if the people designing/building this have ever used GitHub themselves (they reverted some of the other misguided "how on earth did you think that was a good idea?!" features, but not this one).

I have so many more gripes and bugs; clicking "show raw" generally works better for viewing code (or just cloning locally). It's just embarrassing. But it's all pointless to report because nothing gets fixed and it all just keeps getting worse.

GitLab was a "GitHub clone", but I guess now GitHub is turning in a "GitLab clone" by making everything a slow janky barely working mess.

If you just need a place to store your code, self-hosted Gitea is very easy.

Your discoverability will drop to close to zero, and Actions are trickier to set up. Plus, you'll have to come up with a backup plan.

But, you'll be hosting your code on your machine, Microsoft will be out of the loop completely, and you won't be feeding the AI monsters if your repo's are set to "private".

I think it was two things:

1) The original web components proponents[1] there were very heavily into "vanilla" web components. Web components are low-level APIs and just don't have the ergonomics of frameworks without a library to help. For a few elements built by a few true believers, this is ok, but when you scale it out to every component in a complex app with company-wide teams you need the ergonomics and consistency-setting of a declarative and reactive API.

2) The GitHub Next team built their work in React because they required the ergonomics to move fast and they were operating independently from the production app teams. I think the first thing of theirs to be integrated was Projects, and they could probably show that their components had much better DX. Starting from the ergonomics argument, the hiring argument would take hold.

I've seen this happen a few times where web components teams believe that the whole point of them is to not have to use dependencies, hamstring themselves by not using a helper library on that principle, and then get web components as a whole replaced for a proprietary framework in search of ergonomics. If they had used an ergonomic web component helper library, they could have stuck with them.

The irony is that these transitions are usually way easier than a framework-to-framework migration because of web component's inherent interoperability. I still consider that a plus for web components: morally and pratically, technologies should be as easy as possible to migrate away from.

[1] GitHub was so into web components that they regularly sent representatives to W3C meetings to work on them, but a lot of the original team has left the company over the last 10 years.
