Integrating a Qibla compass (boussole Qibla) on a website can be a great tool for users looking for direction towards the Qibla. Below are steps to implement this feature securely and effectively:
Step 1: Choose a Method of Integration
You have a couple of options to integrate a Qibla compass:
- Using a JavaScript Library: There are libraries that can determine the direction of the Qibla based on user’s location.
- Custom Implementation: You can implement the compass functionality using HTML, CSS, and JavaScript.
Step 2: Gather Required Resources
- Geolocation API: This is an API provided by web browsers to get the user’s location. Make sure the use of geolocation is done over HTTPS to protect users.
- Angle Calculation: Use a formula to calculate the angle to the Qibla from the user’s geographic location.
- Compass Design: You will typically need an image or a graphics library to render the compass.
Step 3: Secure Use of Geolocation
- HTTPS: Make sure your website is served over HTTPS as geolocation data can only be accessed securely.
- User Permissions: Always ask for user permission to access their location. Handle cases where users deny permission appropriately.
- Privacy Policy: Make sure to inform users how their location data will be used and ensure compliance with data protection regulations (like GDPR).
Step 4: Calculate the Qibla Direction
You’ll need to calculate the bearing to the Kaaba in Mecca (approximately 21.4225° N, 39.8262° E). Here’s a basic formula to calculate the angle:
function getQiblaDirection(latitude, longitude) {
const kaabaLatitude = 21.4225;
const kaabaLongitude = 39.8262;
const deltaLongitude = kaabaLongitude - longitude;
const x = Math.cos(kaabaLatitude * (Math.PI / 180)) * Math.sin(deltaLongitude * (Math.PI / 180));
const y = Math.cos(latitude * (Math.PI / 180)) * Math.sin(kaabaLatitude * (Math.PI / 180)) -
Math.sin(latitude * (Math.PI / 180)) * Math.cos(kaabaLatitude * (Math.PI / 180)) * Math.cos(deltaLongitude * (Math.PI / 180));
const qiblaAngle = Math.atan2(x, y) * (180 / Math.PI);
return (qiblaAngle + 360) % 360; // Normalize to [0, 360)
}
Step 5: Implement the Compass on Your Website
- HTML Structure: Create a simple HTML structure for the compass.
- CSS Styling: Style the compass using CSS to make it visually appealing.
- JavaScript Logic: Use the Geolocation API to get the user’s position, call the
getQiblaDirection function, and update the compass.
Example Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Qibla Compass</title>
<style>
/* Add styles for the compass */
#compass {
width: 200px;
height: 200px;
border: 5px solid black;
border-radius: 50%;
position: relative;
}
#needle {
width: 2px;
height: 100px;
background: red;
position: absolute;
top: 50%;
left: 50%;
transform-origin: bottom;
transform: rotate(0deg);
}
</style>
</head>
<body>
<div id="compass">
<div id="needle"></div>
</div>
<script>
function getQiblaDirection(latitude, longitude) {
const kaabaLatitude = 21.4225;
const kaabaLongitude = 39.8262;
const deltaLongitude = kaabaLongitude: longitude;
const x = Math.cos(kaabaLatitude * (Math.PI / 180)) * Math.sin(deltaLongitude * (Math.PI / 180));
const y = Math.cos(latitude * (Math.PI / 180)) * Math.sin(kaabaLatitude * (Math.PI / 180)) -
Math.sin(latitude * (Math.PI / 180)) * Math.cos(kaabaLatitude * (Math.PI / 180)) * Math.cos(deltaLongitude * (Math.PI / 180));
const qiblaAngle = Math.atan2(x, y) * (180 / Math.PI);
return (qiblaAngle + 360) % 360;
}
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition((position) => {
const userLatitude = position.coords.latitude;
const userLongitude = position.coords.longitude;
const qiblaDirection = getQiblaDirection(userLatitude, userLongitude);
document.getElementById('needle').style.transform = 'rotate(' + qiblaDirection + 'deg)';
}, (error) => {
console.error('Geolocation error: ', error);
});
} else {
alert('Geolocation is not supported by this browser.');
}
</script>
</body>
</html>
Step 6: Testing
- Cross-Browser and Device Testing: Test the functionality across different browsers and devices to ensure compatibility.
- Error Handling: Implement robust error handling to manage cases where geolocation is denied or fails.
Step 7: Responsive Design
Ensure the compass is responsive, adjusting to different screen sizes and orientations, particularly for mobile users.
Conclusion
Integrating a Qibla compass in a secure way involves thoughtful use of geolocation APIs, secure coding practices, and user privacy considerations. Following these steps will help you create a helpful and user-friendly tool for your website visitors.
Also look here: Using Geolocation API:
If you want to display the Qibla direction based on the user’s current location, you can utilise the Geolocation API to obtain the user’s coordinates (latitude and longitude). Once you have the coordinates, you can calculate the Qibla direction using relevant formulas.
Here’s a simple example of how you can use the Geolocation API to get the user’s coordinates in JavaScript:
javascript
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition);
} else {
console.log(“Geolocation is not supported by this browser.”);
}
function showPosition(position) {
const userLatitude = position.coords.latitude;
const userLongitude = position.coords.longitude;
Use the obtained coordinates to calculate the Qibla direction
}
Using Qibla Calculation Libraries:
Alternatively, you can use Qibla calculation libraries or APIs to directly obtain the Qibla direction based on the user’s location. There are several JavaScript libraries available for this purpose, such as “qibla-js”.
Here’s an example of how you can use the “qibla-js” library to calculate the Qibla direction:
javascript
const qibla = require (qibla-js’);
const qiblaDirection = qibla.getQiblaDirection(userLatitude, userLongitude);
console.log(The Qibla direction is ${qiblaDirection} degrees.);
Displaying the Qibla Compass:
Once you have the Qibla direction, you can display it on your website using a compass or a simple arrow pointing towards the Qibla direction. You can use HTML, CSS, and JavaScript to create an interactive Qibla compass interface for users to easily identify the Qibla direction.
Remember to handle errors gracefully and provide clear instructions for users on how to enable geolocation if it’s required for accurate Qibla direction calculation.
