I honestly can't help myself but Reposting this, the thread initially very clearly said initial results and expressed nuance...
"While the project is still under development, I want to start sharing some stats"
I would hate to see the toxicity of past framework wars enter BlueSky as well...

It's very disappointing that you end up sharing numbers you know are not final yet. They will be misused to create a false narrative.

Models is worth calling out separately, it's something we introduced in signals to allow separating your logic from the view. preactjs.com/guide/v10/si...

One of the bigger challenges I have had promoting @solidjs.com is assuming developers have a general idea of how their tools work. I'd show off fine-grained rendering, and be met with "Isn't that how React works?" I'd find myself educating them more about their existing tools.

one of the most exciting projects we have in @e18e.dev right now is to measure/track perf of all popular meta-frameworks
if you're interested in this or maintain a framework, reach out! its a fun, difficult project 😀
& we're very lucky to have @alexanderkaran.bsky.social leading it (no pressure 😂)

Been thinking a lot about potential digital products to support my open-source work lately, allows me to give things in return on top of the OSS work.

I genuinely think that @npmx.dev is a great thing for junior developers, with our job market becoming harder and harder for junior roles having OSS contributions is a great way to stand out and allows you to point at results

Maintaining open-source can feel extremely isolating, especially when you are few or the only maintainer. Issues often become a you vs them problem or feel like you are not talking to a person, it's an ever-increasing feeling for myself.

The hidden cost of accessing signal.value in your components
Most devs treat signals like useState, but there's a performance cliff... And a solution, why computed matters

This is increasingly challenging throughout OSS repositories that I follow
I cannot unsee the death of the pull request in open source upon us.
PRs from external contributors made a lot of sense when it was hard to write code, and it took lots of time investment (+ lots of thinking!) to do so.
Now that it takes seconds/minutes: dynamics change
