useBooleanState: A Easy, yet Powerful Custom Hook You Will Love

React JS is a popular JavaScript library that allows developers to build complex and interactive user interfaces for web applications. One of the most useful features of React is its hooks system, which enables developers to reuse stateful logic across components. In this article, we will introduce a new custom hook called “useBooleanState”, which simplifies the process of managing boolean state in React components.

The “useBooleanState” hook is a simple custom hook that returns a boolean state value and two functions to update that value – one for toggling the state to true and another for toggling it to false. Here’s an example implementation of the hook:

import { useState, useCallback } from 'react';

function useBooleanState(initialState = false) {
  const [state, setState] = useState(initialState);

  const setTrue = useCallback(() => setState(true), []);
  const setFalse = useCallback(() => setState(false), []);

  return [state, setTrue, setFalse];
}

export default useBooleanState;

By wrapping the setTrue and setFalse functions with useCallback, we can ensure that the same function references are returned every time the hook is called, as long as its dependencies don’t change. This improves performance by preventing unnecessary re-renders of components that use the useBooleanState hook.

Here’s an example of how you might use this custom hook in a React component:

import React from 'react';
import useBooleanState from './useBooleanState';

function ExampleComponent() {
  const [isOpen, openModal, closeModal] = useBooleanState(false);

  return (
    <div>
      <button onClick={openModal}>Open Modal</button>
      <button onClick={closeModal}>Close Modal</button>
      {isOpen && (
        <div>
          <h2>Modal Content</h2>
          <p>This is some content for the modal.</p>
        </div>
      )}
    </div>
  );
}

export default ExampleComponent;

Conclusion

In conclusion, the useBooleanState hook is a simple and useful custom hook that simplifies the process of managing boolean state in React components. By using this hook, developers can write cleaner and more maintainable code while still achieving the desired functionality.
