Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Immer VS mutative - a user suggested alternative

Show HN: Cami.js – A No Build, Web Component Based Reactive Framework
```
It looks like it’s mutating, but both the reducers and update() uses immer* under the hood, so we still respect immutability under the hood.
Cami supports redux devtools so you can use that for time-travel debugging too!

Making Sense of React Server Components
I heard that immutability libraries like immer.js [0] help with this. Anyone go this way and had good success? Is this 'the way'?

How We Fixed Performance With JS Object Variable Mutation
So, that's what we built, and we built it in the most obvious way — using JavaScript Proxy objects to track mutations and reflect those changes across Appsmith’s framework. Initially things looked good — it worked, aside from a few hacks to make some data types work with map and set, and we were following the example of other projects that had similar requirements. If it was good enough for them, it should be good enough for us, right?

The sword refers to immer, the faster and stronger immutable data js tool limu stable version released!
But is immer really the ultimate answer? The performance problem of immer is more prominent in large arrays and deep-level object scenarios. See this issue description, many authors in the community began to try to make breakthroughs, and noticed that structura and mutative, I found that it is indeed many times faster than immer as they said, but it still fails to solve the problem of both fast speed and good development experience. I will analyze the two issues in detail below.

Ramda: A practical functional library for JavaScript programmers
I like immer for this kind of thing: https://github.com/immerjs/immer
It gives you immutable updates without getting bogged down in FP abstractions.
-
Why my variable is being mutated if I make any changes to my data ?
I've always been a huge fan of immer for these case. For your code, it would simply turn into setGridData((prev) => produce(prev, draft => applyChanges(changes, draft)) but I recommend you go over their documentation to fully understand how it works

Is there a better way to do read-only types
If you're trying to make things actually immutable, Object.freeze and deep copies can clutter things up pretty good, have you considered using something like immer? (https://immerjs.github.io/immer/)

5 React Libraries to Level Up your Projects in 2023
If you want to set up from Context, Zustand is your best bet. It offers an extremely simple API that lets you create a store with values and functions. Then, you can access that store from anywhere in your application to read and write values. Reactivity included! If you want to store nested object data in your store, consider using Immer alongside Zustand to easily change nested state.

Changelog #0023 — 🛠️ Internal refactoring and improvements
We took inspiration from the many frameworks we worked with throughout our careers. And maybe surprisingly, Django’s ORM layer impacted our design choices and the API quite a bit. The resulting framework relies on Zod for schemas and validation and Valtio for React integration.
-
Is redux and thunks still used or are there other alternatives for it now?
Valtio is like simplified MobX
-
Why is building a UI in Rust so hard?
Even simpler than Zustand are state-atom libraries like jotai or recoil, or proxy based ones like valtio. Here's some discussion about the differences.

How to implement state management inside a simple JavaScript app
There is a package developed around this proxy concept called Valtio which is available for JavaScript, React, and so on... feel free to check and star it on Github.
-
What is being used right now for ioc/state-managment?
I'm switching from redux-saga to valtio (https://github.com/pmndrs/valtio) for now. It's simple and easy to use, everything's great so far.
-
Ask HN: What is your favorite front end state management solution?
I like valtio, works w/ React or just js. Has subscribe, derive, and more.

Explanation on how Redux or React Context could help and picking the best option
Jotai and Valtio are both also really good. Recently looked at Nanostore as well and has some similarity to Jotai and Recoil.
-
Notes on LiveView Components and JS interactions
Since we want the React component to react to an external change, using a state manager makes this easy. We will use Valtio here by example. For this library, change the esbuild config to --target=es2020 instead to remove some warnings (for example, the Zustand library is ok).
What are some alternatives?
immutability-helper - mutate a copy of data without changing the original source
redux - A JS library for predictable global state management
immutable-js - Immutable persistent data collections for Javascript which increase efficiency and simplicity.
MobX - Simple, scalable state management.
redux-toolkit - The official, opinionated, batteries-included toolset for efficient Redux development
zustand - 🐻 Bear necessities for state management in React
Recoil - Recoil is an experimental state management library for React apps. It provides several capabilities that are difficult to achieve with React alone, while being compatible with the newest features of React.
jotai - 👻 Primitive and flexible state management for React
react-query - 🤖 Powerful asynchronous state management, server-state utilities and data fetching for TS/JS, React, Solid, Svelte and Vue. [Moved to: https://github.com/TanStack/query]
