Svelte 5 Released

I love Svelte and use it for all my personal projects and all company projects (except strictly static sites are still built with just 11ty but I hate it and want to move off it).

But I'm going to wait a bit on v5 for the company, scanning all the issue headlines, it looks like there are a still a lot of unresolved edge cases: https://github.com/sveltejs/svelte/issues

As for my latest personal project, upgrading right now so I can help find more of those edge cases :D

can I do async derived stores by default yet? It was kinda tricky to get working in svelte 4 and even Square/svelte-store wasn't super ergonomic. Would be super nice if it was built in

Where would one even start learning more about front-end development in today's world? Ignoring the dizzying amount of frameworks, how could I become knowledgeable enough to connect my back-end experience to design the "full stack?"

Good work! I’m not really sold on the runes stuff though (tldr: https://svelte.dev/blog/runes)

The old way is a bit “magical” in a sense that it does some stuff under the hood to implement the intention behind your code, but it reads really straightforward:

  let counter = 0;
  // ...
  {counter}

`let` in a .svelte compoment makes a variable reactive. If your state is outside a component, you use stores.

With the `$store` rune, the way you make reactive stores inside and outside components is the same, but it only works in .svelte.js/ts. The unification is great – but why not just use `let` in .svelte.js, too?

  // counter.svelte.js
  export function createCounter() {
    let count = 0;
    return {
      get count() { return count },
      increment: () => count += 1
    };
  }

  // App.svelte
  
    import { createCounter } from './counter.svelte.js';
    const counter = createCounter();
  

  
    clicks: {counter.count}
  

I understand it can be really tricky – e.g. you might want to use let for things that are not modified in runtime and do not need reactivity, but it should be possible to determine in compile time. (Actually after writing this all up I think I know why Svelte went with runes instead, haha!)

But again – really good work and I hope to try it out on my next project!

Definitely try Astro for static sites, I'm loving it!
