Why did Redux Toolkit not suit you, and you switched to Effector?

Redux Toolkit is a powerful tool for state management in React applications, simplifying work with Redux by reducing boilerplate and code size. However, in some projects, it may seem bulky or excessive, especially if the application is not very large or if a more reactive and declarative approach is desired.

Effector is a library for state management focused on reactive programming. It offers:

• A simpler and more understandable API for reactive data streams.
• Better performance through optimized component updates.
• Flexibility in building complex logic without unnecessary boilerplate.

Reasons for switching from Redux Toolkit to Effector may include:

• Desire to reduce boilerplate and simplify code.
• More convenient handling of asynchronous operations and side effects.
• Better integration with reactive programming style.

Example of Effector:

import { createStore, createEvent } from 'effector';

const increment = createEvent();
const counter = createStore(0)
  .on(increment, (state) => state + 1);

counter.watch(state => console.log(state));

increment(); // Will output 1
