react-use-reactive v1.0.0

React useReactive

react-use-reactive is a custom React hook that allows you to create reactive objects using useState. It supports deep reactivity and updates, even for nested objects.

Installation

To install the react-use-reactive hook, run the following command in your project directory:

npm install react-use-reactive

Usage

First, import the useReactive hook:

import useReactive from 'react-use-reactive';

Next, use the useReactive hook in your functional components:

import React from 'react';
import useReactive from 'react-use-reactive';

const App = () => {
  const state = useReactive({ count: 0, nested: { value: 0 } });

  const incrementCount = () => {
    state.count++;
  };

  const incrementNestedValue = () => {
    state.nested.value++;
  };

  return (
    <div>
      <div>Count: {state.count}</div>
      <button onClick={incrementCount}>Increment Count</button>
      <div>Nested value: {state.nested.value}</div>
      <button onClick={incrementNestedValue}>Increment Nested Value</button>
    </div>
  );
};

export default App;

Usage example with form binding:

...

const state = useReactive({ user: {firstName: '', lastName: ''} });

...

<input
  type="text"
  value={state.user.firstName}
  onChange={(e) => state.user.firstName = e.target.value}
/>
<input
  type="text"
  value={state.user.lastName}
  onChange={(e) => state.user.lastName = e.target.value}
/>

This allows for nested objects to also become reactive, instead of a non-reactive object being assigned to a reactive property.
