useOrientation Hook

The useOrientation hook is designed for both React web and mobile applications, providing a comprehensive solution to monitor and respond to orientation changes. This hook can track the orientation of the device or a specific HTML element, offering valuable data for responsive and dynamic UIs.

Features

• Dynamic Orientation Tracking: Continuously updates with the device's current orientation angle and type, as well as the orientation of a specified element.
• Versatile Usage: Capable of tracking either the device's window or a specified element's orientation.
• Detailed Information: Provides orientation angle, type (landscape or portrait), aspect ratio, and orientation state of the referenced element.
• Server-Side Rendering (SSR) Compatibility: Handles environments without a window object, making it suitable for server-side rendering.

Installation

Install Specific Hook

npm install @custom-react-hooks/use-orientation

or

yarn add @custom-react-hooks/use-orientation

Install Complete Hook Collection

npm install @custom-react-hooks/all

or

yarn add @custom-react-hooks/all

Importing the Hook

The useOrientation hook must be imported using a named import as shown below:

Named Import:

import { useOrientation } from '@custom-react-hooks/use-orientation';

This approach ensures that the hook integrates seamlessly into your project, maintaining consistency and predictability in how you use our package.

Usage Example

import React, { useRef } from 'react';
import { useOrientation } from '@custom-react-hooks/all';

const OrientationComponent = () => {
  const elementRef1 = useRef(null);
  const elementRef2 = useRef(null);

  const elementOrientation1 = useOrientation(elementRef1, false);
  const elementOrientation2 = useOrientation(elementRef2, false);
  const windowOrientation = useOrientation(undefined, true);

  return (
    <div>
      <div ref={elementRef1}>
        <strong>Element 1: </strong> {elementOrientation1.elementOrientation}
        <br />
        <strong>Aspect Ratio:</strong>
        {elementOrientation1.aspectRatio ? elementOrientation1.aspectRatio.toFixed(2) : 0}
      </div>
      <div ref={elementRef2}>
        <strong>Element 2: </strong>
        {elementOrientation2.elementOrientation}
        <br />
        <strong>Aspect Ratio:</strong>
        {elementOrientation2.aspectRatio ? elementOrientation2.aspectRatio.toFixed(2) : 0}
      </div>
      <p>Window Orientation: {windowOrientation.type}</p>
    </div>
  );
};

export default OrientationComponent;

In this example, the useOrientation hook is used to monitor the orientation of both the device's window and a specific image element.

API Reference

Parameters

• elementRef (Optional): A React RefObject to an HTML element.
• trackWindow (Optional): Boolean to track the device's window orientation.

Returns

• angle: The current orientation angle of the device or element in degrees.
• type: The orientation type ('landscape-primary', 'landscape-secondary', 'portrait-primary', 'portrait-secondary').
• aspectRatio: The aspect ratio of the referenced element (if provided).
• elementOrientation: The orientation of the referenced element ('landscape' or 'portrait').

Use Cases

• Responsive Design: Adjust layouts and UI elements based on device orientation.
• Device Orientation Features: Implement features that depend on device orientation, like games or 3D views.
• Element-Specific Orientation: Change the functionality or display of specific elements based on their orientation.
• Aspect Ratio Detection: Detect and respond to changes in the aspect ratio of an element.
