Welcome to the Ultimate Guide to Using nprogress
nprogress is a simple yet powerful JavaScript library that helps you create and manage progress bars with ease. This library is designed to be as lightweight and flexible as possible, allowing you to integrate it seamlessly into your web applications.
Basic Usage
To get started with nprogress, you need to include the necessary CSS and JavaScript files in your project:
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/nprogress/0.2.0/nprogress.min.css" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/nprogress/0.2.0/nprogress.min.js"></script>
Initialize nprogress
You can start using nprogress by initializing the progress bar when your application starts loading and completing it when the loading finishes:
// Start the progress bar
NProgress.start();
// Complete the progress bar
NProgress.done();
Useful API Methods
nprogress provides several useful API methods to control the behavior of the progress bar:
- NProgress.start(): Starts the progress bar.
- NProgress.done(): Completes the progress bar.
- NProgress.set(percentage): Sets the progress to a specific value. Example:
NProgress.set(0.5); // Sets progress to 50%
NProgress.inc(0.1); // Increments progress by 10%
NProgress.configure({ showSpinner: false });
App Example
Here’s a simple app example that uses nprogress to show loading progress:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/nprogress/0.2.0/nprogress.min.css" />
<title>nprogress Example</title>
</head>
<body>
<button onclick="loadData()">Load Data</button>
<script src="https://cdnjs.cloudflare.com/ajax/libs/nprogress/0.2.0/nprogress.min.js"></script>
<script>
function loadData() {
NProgress.start(); // Start progress
// Simulate data loading with a timeout
setTimeout(function() {
NProgress.done(); // Complete progress
}, 2000);
}
</script>
</body>
</html>
With just a few lines of code, you can now have a fully functional progress bar integrated into your web application!
