didact

It's a bit older (and focused on web), but you can try this https://github.com/pomber/didact At a high level though, you create a tree of nested objects. Each has a handful of special properties (children which contains an array of child objects being the most interesting to users). The rest of the properties are used to interface with the rendering engine by passing it configuration and (usually) event functions it can call when something happens. That tree of objects gets passed to the rendering engine which turns the tree into some kind of output (DOM, Canvas, WebGL, Ink, etc)[0]. When something happens (an external event, a timer, event from the render engine, etc), your code potentially changes the object tree. React then walks that tree and uses a few shortcuts to quickly detect what has changed. Instead of re-rendering everything,

I gotcha covered there :) See my "Idiomatic Redux" blog post series [0] for info on how Redux was designed, why it works the way it does, and the implementation details of both the Redux core, React-Redux, and our new Redux Toolkit package. I also recommend the post "Build Yourself a Redux" [1] as the best "build a mini Redux" post I've seen. Rodrigo Pombo's "Didact" series [2] does the same process but for React, showing how to build a miniature reconciler that even includes hooks. I also have links to further articles about React's implementation [3] as well. Finally, I specifically recommend reading my post "A (Mostly) Complete Guide to React Rendering Behavior [4] and Dan Abramov's extensive article "A Complete Guide to `useEffect`" to better understand how React behaves and how to use it correctly.
