Introduction to Reduck

Reduck is a powerful state management library that simplifies and enhances the way developers manage state in JavaScript applications. By integrating best practices from Redux and adding improvements, Reduck provides a more streamlined API that is both intuitive and versatile.

Key Features and APIs of Reduck

Here is a detailed explanation of some of the most useful APIs provided by Reduck, along with code snippets to demonstrate their usage:

1. createStore

This API creates a new store with an initial state:

import { createStore } from 'reduck';

const initialState = {
  counter: 0,
};

const store = createStore(initialState);

2. createAction

This API creates an action that can be dispatched to the store:

import { createAction } from 'reduck';

const increment = createAction('INCREMENT');

store.dispatch(increment());

3. createReducer

This API helps create a reducer to handle actions:

import { createReducer } from 'reduck';

const counterReducer = createReducer((state, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return { counter: state.counter + 1 };
    default:
      return state;
  }
});

store.addReducer('counter', counterReducer);

4. useSelector

This API allows you to select a part of the state from the store:

import { useSelector } from 'reduck';

const counter = useSelector((state) => state.counter.counter);

5. useDispatch

Dispatch actions from within your components using this API:

import { useDispatch } from 'reduck';

const dispatch = useDispatch();

const incrementCounter = () => {
  dispatch(increment());
};

Building an App with Reduck

Here is a complete example of a simple counter application using the previously described APIs:

import React from 'react';
import { Provider } from 'reduck';
import { createStore, createAction, createReducer, useSelector, useDispatch } from 'reduck';

const initialState = { counter: 0 };
const store = createStore(initialState);

const increment = createAction('INCREMENT');

const counterReducer = createReducer((state, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return { counter: state.counter + 1 };
    default:
      return state;
  }
});

store.addReducer('counter', counterReducer);

const CounterApp = () => {
  const counter = useSelector((state) => state.counter.counter);
  const dispatch = useDispatch();

  const incrementCounter = () => {
    dispatch(increment());
  };

  return (
    

      
Counter: {counter}
      Increment
    
  );
};

const App = () => (
  
    
  
);

export default App;

This example demonstrates how Reduck APIs can be used to manage state in a React application efficiently. By leveraging the simplicity and power of Reduck, developers can focus more on building feature-rich applications.
