MobX VS Cycle.js

States can also be organized in some central places (aka. stores). You can use Tini Store (very simple, ~50 lines) or other state management solutions such as MobX, TinyX, ...

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

MobX

Mutable-based: leverages proxy to create mutable data sources which can be directly written to or reactively read from. Candidates in this group are MobX and Valtio.

Looks good! FWIW I always felt the observable pattern much more intuitive than the redux/reducer style. Something like https://mobx.js.org/

Things get hairy in both, but redux pattern feels so ridiculously ceremonially to effectively manage a huge global state object with a false sense of "purity".

Observables otoh say "fuck it, I'm mutating everything, do what you want with it".

MobX Documentation

There's also others libraries like https://github.com/mobxjs/mobx which aren't specific to RN but can be used in any JS environment.

Valtio is like simplified MobX

Cycle

This is the standard way of going about things in Mithril and Cycle. Elm as well doesn't use an XML knockoff for view code- and as a fun fact, the original version of React didn't either.

For example, an FRP framework (created by the same author who later wrote the callbag spec): https://cycle.js.org/

TypeScript is relatively mainstream at this point, and I think that's good news. If you want to crank the type-safety and pure FP dials on it to 11, you certainly can do that. I have a project that I've based largely on this post, including the "hardcore" section. However, instead of Redux and otherwise plain React, I've chosen to use Cycle.js and the lessons from this post to use React in a very purely Functional Reactive Programming Way.

This post links to a PureScript project that is probably the easiest PS framework around.

ReScript + rescript-react is a good alternative. Less safe, waaaay more verbose; but backed by Facebook.

This is quite cute (in TypeScript though): https://github.com/cyclejs/cyclejs

And Yew is super cool, it goes the WASM route (in Rust): https://github.com/yewstack/yew

From now on I was on what I would call a typical open source trajectory. I used the Cycle.js framework to rewrite my frontend and in that process I hit some walls. I eventually figured that the error was on my side and that I was just missing some information to avoid the error. To spare others the hours of debugging I started to contribute small patches to the documentation. At the same time I also found some missing features that I voiced in GitHub issues.
