rxdux-state-manager

A powerful and flexible state management library developed using RxJS, inspired by the Flux architecture. Ideal for managing complex state in React applications.

Installation

Easily integrate rxdux-state-manager into your project:

npm install rxdux-state-manager

or

yarn add rxdux-state-manager

Tip: This library can be used as a React hook for efficient state management.

Getting Started with rxdux-state-manager

Initializing the State Manager

Initialize the state manager to manage your application's state effectively.

counter-state-manager.ts

import { easyStateManager } from "rxdux-state-manager";

export const {
  useStateManager: useGlobalState,
  $state: $globalState,
  updateState: updateGlobalState,
} = easyStateManager({
  count: 0,
  person: {
    name: "John Doe",
    age: 22,
  },
});

class CounterActions {
  incr = () => {
    updateGlobalState((draft) => {
      draft.count++;
    });
  };

  incrAge = () => {
    updateGlobalState((draft) => {
      draft.person.age++;
    });
  };
}

export const counterActions = new CounterActions();

Key Feature: When passing a function to the updater, the draft argument can be mutated freely. Changes will be made immutable and become the next state once the producer ends.

Using the Hook to Access and Update State

Learn how to use the hook to consume and update state in your React components.

Counter.tsx

import React from "react";
import { counterActions, useGlobalState } from "./counter-state-manager";

export default function Counter() {
  const { count } = useGlobalState("count");
  
  return (
    <div className="p-2 rounded border border-blue-500">
      <p className="text-purple-600">{count}</p>
      <button className="border p-1 rounded" onClick={counterActions.incr}>
        Increment
      </button>
    </div>
  );
}

Why Use rxdux-state-manager?

1. Selective Rerendering: Use const { count } = useGlobalState('count') to rerender components only when specific state keys change, improving performance.
2. Effortless State Updates: Simplify state updates with onClick={counterActions.incr} without the need for dispatchers.

Accessing Current State with RxJS BehaviorSubject

$globalState is an RxJS BehaviorSubject, allowing you to access the current state anywhere in your application:

const state = $globalState.value; 
console.log(state.person.age);

Using Multiple State Keys with useGlobalState

The useGlobalState hook can take multiple arguments for accessing various state keys:

const { count, person } = useGlobalState("count", "person");
console.log({
  count,
  person,
});

Advantages of Using rxdux-state-manager

• Efficient State Management: Manage your application’s state efficiently with RxJS and React.
• Scalable and Maintainable: Ideal for complex applications requiring a scalable and maintainable state management solution.
• Improved Performance: Optimize performance with selective rerendering and immutable state updates.
