signals VS PromiseKit

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/...

All the frameworks are starting to adapt them. You can easily add them to react project as well. https://preactjs.com/blog/introducing-signals/

Signals are a design paradigm for reactive programming which have recently trended in the JS frontend space. For e.g., https://preactjs.com/blog/introducing-signals/

Compare Vue's reactivity system to the principles the Preact authors write about here:

Reactivity libraries are at the heart of modern web component frameworks like Solid, Qwik, Vue, and Svelte. And in some cases you can add fine-grained reactive state management to other libraries like Lit and React. Reactively comes with a decorator for adding reactive properties to any class, as well as prototype integration with Lit. Preact Signals comes with a prototype integration with React. Expect more integrations as these reactivity cores mature.

State solution should not be a framework, this is what I dislike in riverpod as well.. its a FRAMEWORK... compare to the simple useSignal hook that preact has https://preactjs.com/blog/introducing-signals/ this looks like an overkill.

Looks like it's coming from here https://preactjs.com/blog/introducing-signals

Sciter got native (built-in) Signal implementation made after PReact's Signals;

Do you use PromiseKit?

I use PromiseKit to handle async codes. It's really easy to use for basic uses like this

The most typical way to solve this problem is by using Combine's Future or PromiseKit's Promise, or by using RxSwift's flatMap. If you're interested on how this works under the hood, I plan to write another article for this case, but for now you can check my code for a simple Promise in this gist, or check this quite old but incredibly mind blowing talk from Javi Soto.

Besides that, you can use a promise library, like PromiseKit.
