signals VS redux

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;

Redux

redux - Redux is a key tool used in managing state across an application. This can be used with any web technology including React, Vue and Angular docs

Redux is a client-state library.

react-redux: A powerhouse for efficient state management and data flow control. Learn more

Reducer-based: requires dispatching actions to update a big centralised state, often called a “single source of truth”. In this group, we have Redux and Zustand.

I am _thrilled_ to announce that:

Redux Toolkit 2.0 is LIVE!!!

- https://github.com/reduxjs/redux-toolkit/releases/tag/v2.0.0

This major version has new features, faster perf, smaller bundle size, and removes deprecated options.

It's accompanied by majors for all our Redux family packages

## RTK 2.0:

- a new `combineSlices` method for lazy-loading reducers - Updates to `createSlice` to include a `selectors` field and allow defining thunks inside

- Immer 10 w/ faster updates

- Removal of deprecated options

See the migration guide:

- https://redux.js.org/usage/migrations/migrating-rtk-2

All of the Redux libraries now have modernized packaging with full ESM/CJS compat. They also ship modern JS (no transpiling for IE11), which means smaller bundle sizes.

We've also done byte-shaving work to shrink the bundles (extracting error messages, de-duping imports)

## Redux core 5.0:

- The TS conversion we did in 2019!

- Action types _must_ be strings

- `UnknownAction` as the default action type

- Better preloaded state types

- Internal subscription improvements

- Still marks `createStore` as deprecated!

- https://github.com/reduxjs/redux/releases/tag/v5.0.0

## React-Redux 9.0:

- *Now requires React 18 and RTK 2.0 / Redux 5.0*

DEV is a Rails monolith, which uses Preact in the front-end using islands architecture. The reason why I mention all this is that it's not a full-stack JavaScript application, and there is no state management library like Redux or Zustand in use. The data store, for the most part on the front end, is all data attributes.

Oh hey, that's my post!

(yes I spend too much time refreshing HN :) )

FWIW I did end up with a packaging combination that seems to work sufficiently. I never did fix the "FalseCJS" issue that `are-the-types-wrong` is detecting. I played with double-emitting TS typedefs, and the `tsup` tool _does_ actually have support for that now (added by Andrew Branch from the TS team). So it might be more feasible now. But ultimately I decided I was tired of messing with packaging setup and that what I've got is good enough. (hopefully)

We're actually about to launch Redux Toolkit 2.0 and Redux 5.0 this week, assuming the last couple pieces come together. Here's the latest RCs - you can see the current `package.json` files in there:

- https://github.com/reduxjs/redux-toolkit/releases/tag/v2.0.0...

- https://github.com/reduxjs/redux/releases/tag/v5.0.0-rc.1
