Comparing global state libraries with React Hooks
I have been developing several libraries for global state with React Hooks. While developing them, I was interested in comparing with existing libraries. It turns out there are various points to compare, showing characteristics of such libraries.
I started creating a comparison table in the issue. As the table becomes bigger, let's create a separate repo so that library authors can contribute improving the comparison.
- Does it use React Context? What is context value?
- Does it use subscription for state propagation?
- Does it have render optimization? What is the technique?
- Does it have dependencies? What are they?
- What's the level of compatibility with concurrent rendering?
- Bundle size (Minified + Gzipped)
Render optimization means avoiding unnecessary re-renders.
If a state object is { a: 1, b: 2 } and a component only uses a,
it won't re-render if only b is changed.
For "tearing" and "state branching", refer https://github.com/dai-shi/will-this-react-global-state-work-in-concurrent-mode. These are not necessarily problems depending on requirements.
