redux VS effector-react

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

In its docs, Astro recommends nanostores, but I’ve used effector in the past. And LOVED IT. So I’ve used it for this project as well.

I've been using effector, together with the apollo-client for the last few years and, while it works, it's completely detached from the actual screens. In other words, you need to fetch everything (at startup) you might use at some point and it stays in the memory for the entire duration of the session. Error handling is also tricky as you need to explicitly subscribe to the specific error stores in order to render them. And, if something goes wrong, it's tricky to tell what data is actually used in the current screen, so it's almost impossible to do the Retry efficiently. OTOH the screens are nice and simple - no spinners, the data is just there, thus the app feels (and is) fast.

Actually, Svelte uses Effector for state management under the hood. You can read more about it here: https://effector.dev/. It also has bindings for other frameworks including React, Vue and Solid. Effector is a little not beginner-friendly, but once you truly understand it, Effector becomes a very powerful.

A state-management library.

Effector it is the another way to create state and business logic for your frontend application.

https://effector.dev/ here you go

Then I found Effector which seems to have the same features, and SolidJs support.

Where’s effector?
