Here’s a step-by-step tutorial on how to create browser notifications in JavaScript using notifications retrieved from an API.
Step 1: Set up the HTML structure Create an HTML file and add the following structure
<!DOCTYPE html>
<html>
<head>
<title>Browser Notifications Example</title>
</head>
<body>
<h1>Browser Notifications Example</h1>
<script src="script.js"></script>
</body>
</html>Step 2: Create the JavaScript code Create a JavaScript file called script.js and add the following code
// Request permission to show notifications
Notification.requestPermission().then(function(permission) {
if (permission === 'granted') {
// Permission granted, load notifications from the API
loadNotifications();
}
});
// Function to load notifications from the API
function loadNotifications() {
fetch('https://api.example.com/notifications')
.then(function(response) {
return response.json();
})
.then(function(notifications) {
// Iterate over each notification
notifications.forEach(function(notification) {
// Show notification
showNotification(notification.title, notification.body);
});
})
.catch(function(error) {
console.error('Error loading notifications:', error);
});
}
// Function to show a browser notification
function showNotification(title, body) {
if (Notification.permission === 'granted') {
// Create a new notification
var notification = new Notification(title, {
body: body,
});
// Open a new tab when the user clicks on the notification
notification.onclick = function() {
window.open('https://example.com');
};
}
}Step 3: Test the code Open the HTML file in a web browser, and the script will request permission to show notifications. If the permission is granted, it will load notifications from the specified API and show them as browser notifications. When you click on a notification, it will open a new tab with the URL https://example.com.
