Welcome to @patrissoljuns/react-click-outside 🎉

Looking for an easy and efficient way to handle click-away interactions in your React application? Look no further! Introducing @patrissoljuns/react-click-outside, a lightweight and powerful package that offers a hassle-free solution for handling click-away events in React applications. Whether you're working on dropdowns, modals, or any other UI components that need to close when a user interacts outside of them, this package has got your back.

🔥 Features

• Versatile: Support for both functional components (hooks) and class components. Choose the method that works best for you!
• Flexible: Customizable event types (click, mousedown, mouseup, keydown, touchstart, etc.)
• Scoped: Define the target element or document where the event listeners will be attached, making it ideal for restricting click-away detection to a particular section or container in your application.
• Optimized: Streamlined event handling and clean-up ensure top-notch performance and silky-smooth user experiences.
• Type-safe: Crafted with TypeScript for built-in type safety.

📦 Installation

npm install @patrissoljuns/react-click-outside
# or
yarn add @patrissoljuns/react-click-outside

🚀 Usage

Declarative Component

Here's a simple example of using the ClickOutsideListener component to close a dropdown menu:

import React, { useState } from 'react';
import ClickOutsideListener from '@patrissoljuns/react-click-outside';

const MyComponent = () => {
  const [dropdownOpen, setDropdownOpen] = useState(false);

  const handleClickOutside = () => {
    setDropdownOpen(false);
  };

  const toggleDropdown = () => {
    setDropdownOpen(!dropdownOpen);
  };

  return (
    <div>
      <button onClick={toggleDropdown}>Toggle Dropdown</button>
      {dropdownOpen && (
        <ClickOutsideListener onClickOutside={handleClickOutside}>
          <div className="dropdown">
            {/* Dropdown content */}
            Click outside this element to close it!
          </div>
        </ClickOutsideListener>
      )}
    </div>
  );
};

useClickOutsideListener Hook

Alternatively, you can use the useClickAwayListener hook to programmatically handle click-away events

import React, { useState } from 'react';
import { useClickOutsideListener } from '@patrissoljuns/react-click-outside';

const ExampleComponent = () => {
  const [showDrawer, setShowDrawer] = useState(false);
  
  const containerRef = useClickOutsideListener<HTMLDivElement>({
    onClickOutside: () => setShowDrawer(false), 
    events: ['keydown', 'touchstart']
  });

  return (
    <div ref={containerRef}>
      <button onClick={() => setShowDrawer(true)}>Toggle drawer</button>
      {showDrawer && <div>My beautiful drawer</div>}
    </div>
  );
};

📚 API

useClickOutsideListener

| Prop | Type | Description | |----------|:-------------:|:-------------:| | onClickOutside required | (event: MouseEvent | TouchEvent | KeyboardEvent | FocusEvent) => void | A callback function that is triggered when an event specified in the events prop occurs outside the children element. It receives the event object as its argument, allowing you to perform custom actions based on the event type, target, or other properties | events Default to ['mousedown'] | Array<'mousedown' | 'mouseup' | 'mouseover' | 'click' | 'touchstart' | 'touchend' | 'keydown' | 'keyup' | 'focus' | 'blur'> | An array of event types to listen for. This allows you to customize the events that trigger the onClickOutside callback | | scope Default to document | HTMLElement | Document | null | An optional parameter that allows you to specify the target element, document, or null where the event listeners will be attached. This can be useful in cases where you want to limit the click-away detection to a specific section or container of your application. If scope is set to null, no event listener will be attached. If scope is undefined, the document will be used as the default value. This flexibility helps handling the initial state of refs more easily and avoid potential issues or unexpected behavior when working with the useClickOutsideListener hook. |

ClickOutsideListener

Same with useClickOutsideListener above plus the following:

| Prop | Type | Description | |----------|:-------------:|:-------------:| | children required | React.ReactElement | A single React element that the ClickOutsideListener will wrap. This element will be monitored for click events happening outside of it. The ClickOutsideListener will execute the provided onClickOutside callback when such an event occurs | | wrapperComponent | React.ElementType | An optional custom component that will be used as the wrapper for the children element. By default, ClickOutsideListener uses a React fragment to avoid altering the DOM structure. However, if you need to use a specific HTML element or custom component as the wrapper, you can provide it through this prop | | wrapperProps | React.HTMLAttributes<HTMLElement> | Optional object containing any additional props to apply to the wrapperComponent if present

📖 Examples

import React, { useState } from 'react';
import ClickOutsideListener, { UseClickOutsideListenerOptions } from '@patrissoljuns/react-click-outside';

const App = () => {
    const [isModalOpen, setIsModalOpen] = useState(false);

    const closeModal: UseClickOutsideListenerOptions['onClickOutside'] = (event) => {
        if (event instanceof KeyboardEvent && (event.key === 'p' || event.key === 'Escape')) {
            setIsModalOpen(false);
        }
    };

    const openModal = () => {
        setIsModalOpen(true);
    };

    return (
        <div>
            <button onClick={openModal}>Open Modal</button>
            {isModalOpen && (
                <ClickOutsideListener onClickOutside={closeModal} events={['keydown']}>
                    <div className="modal">
                        <h2>Modal Title</h2>
