ProBar – A modern progress bar with Timer.

Introduction to the ProBar: A Modern Progress Bar with Timer

In many applications, whether it's a website, mobile app, or desktop software, displaying progress or loading time can be essential to provide a better user experience. A progress bar is a simple yet effective way to show the progress of a task, letting users know how much longer they need to wait. The ProBar is a modern progress bar with timer that can be easily integrated into your project, making it easy to keep users informed and engaged.

What is the ProBar?

The ProBar is a JavaScript library designed to provide a visually appealing and intuitive way to display progress and loading times. It offers a range of customization options, allowing developers to tailor the appearance and behavior of the progress bar to suit their specific needs. The ProBar can be easily integrated into HTML, CSS, and JavaScript projects, making it a versatile tool for a wide range of applications.

Getting Started with the ProBar

To get started with the ProBar, follow these simple steps:

Step 1: Add the ProBar JavaScript file

The first step is to add the ProBar JavaScript file to your HTML file. You can download the ProBar library from the official website and host it on your own server or use a CDN like Unpkg.

Here is an example of how you can add the ProBar JavaScript file to your HTML file:

<script src="https://unpkg.com/pro-bar@1.3.0/dist/pro-bar.min.js"></script>

Step 2: Create a ProBar instance

To create a ProBar instance, you need to call the ProBar constructor and pass it the required parameters. The ProBar constructor takes two parameters: the first is an optional container element, and the second is an options object that defines the settings for the progress bar.

Here is an example of how you can create a ProBar instance:

const probar = new ProBar({
  container: document.getElementById('progress-bar'),
  options: {
    strokeWidth: 10,
    strokeColor: '#00698f',
    animated: true,
    interval: 100,
  },
});

Step 3: Configure the ProBar options

The options object allows you to customize various aspects of the ProBar, such as the stroke color, stroke width, animation, and interval. You can modify these settings by passing a new options object to the ProBar constructor.

Here are some common options you can use:

• strokeColor: Sets the color of the progress bar.
• strokeWidth: Sets the width of the progress bar.
• animated: Enables or disables animation on the progress bar.
• interval: Sets the interval between updates to the progress bar.
• maxValue: Sets the maximum value for the progress bar.

Step 4: Update the progress bar

To update the progress bar, you can call the update method and pass it a value between 0 and 1, representing the progress. You can also pass an optional step parameter to update the progress bar in increments.

Here is an example of how you can update the progress bar:

probar.update(0.5); // updates the progress bar to 50%
probar.update(0.75, 20); // updates the progress bar to 75% in 20 steps

Step 5: Clear the progress bar

When you're done using the ProBar, you can clear it by calling the clear method. This method removes the ProBar element from the DOM and releases any resources associated with it.

Here is an example of how you can clear the ProBar:

probar.clear();

Additional Features

The ProBar offers several additional features that can enhance your user experience:

• Timer: The ProBar can display a timer to show the elapsed time, which can be useful for tasks that take a significant amount of time.
• Labels: You can add custom labels to the ProBar to provide additional context or instructions.
• Events: The ProBar provides a range of events that can be used to track changes in the progress bar or timer.
• Responsive design: The ProBar is designed to be responsive, making it suitable for use on a range of devices and screen sizes.
