Svelte 5: Runes

  website that makes it easy to find neovim plugins

I originally created https://neovimcraft.com in Svelte to learn how it works.

I found `$:` to be extremely confusing and full of weird quirks and completely turned me off to svelte entirely -- and decided to rip it out entirely for something simpler.

Runes seem like a clear improvement, but brings Svelte a step closer to React -- which hurts its appeal to me.

The difference between `let counter = $state(0)` and `const [counter, setCounter] = useState(0)` is near its initial value -- zero.

  Parse in reverse (by Rich-Harris)

I snooped around Rich's, GitHub history and found he's working on esarp[1], a package to convert an AST into code. It uses Bun for development and testing!

Crazy theory: esarp will be part of a transpiler that converts Svelte 4 code to Svelte 5 code. I'm not sure if that's actually the case or if it's even technically possible. But it would be really cool!

  Discontinued functional reactive programming for JavaScript

  

It's amazing how far back all the research and experimentation goes on reactive Web/JS tech, e.g. Brown PLT's work on Flapjax starting back in 2006, even before the JS renaissance kicked off by googl's V8!

It might be interesting to do a compare/contrast with v5's Runes and Flapjax's implementations.

• lit

  141 17,535 9.4 TypeScript

  Lit is a simple library for building fast, lightweight web components.

  

That is exactly my experience after trying svelte/sveltekit for 2 months. Loved svelte at first sight but soon their own invented complexity (and a very confusing error log) made me realize that I was changing React for something quite similar (with a bunch of different problems). In place of going back to React tho, I tried the next one in my list: Lit. No regrets, found the (powerful) simplicity I was looking for. Give it a try before getting back to React: https://lit.dev/

• signals

  24 3,512 8.8 TypeScript

  Manage state with style in every framework

  

Putting the runic terminology aside and looking into how the signal primitive is implemented should dispel the magic. I learned a lot from examining preact's implementation: https://github.com/preactjs/signals/blob/main/packages/core/...

• rfcs

  74 4,827 2.9

  RFCs for substantial changes / feature additions to Vue core (by vuejs)

  

```

We started experimenting with this ling of thought almost 3 years ago:

- First take (ref sugar), Nov 2020: https://github.com/vuejs/rfcs/pull/228

- Take 2, Aug 2021: https://github.com/vuejs/rfcs/pull/368

- Take 3, Nov 2021: https://github.com/vuejs/rfcs/discussions/369

We provided it as an experimental feature and had a decent number of users trying it out in production. The feedback wasn't great and eventually decided to drop it. https://github.com/vuejs/rfcs/discussions/369#discussioncomm...
