Have you ever wanted to elevate your web experience with smooth scrolling? Introducing Easy Scroll, a lightweight native JavaScript library that helps you achieve a fluid scrolling motion just the way you want it. In this article, we will guide you through the steps to implement this library, its key features, and how to troubleshoot any issues that arise along the way.

Features of Easy Scroll

• Lightweight – ~3 KB before gzip
• No dependencies required
• Scroll in any direction – left, right, down, or up
• Specify the exact number of pixels to scroll
• Flexible usage with any scrollable element – windows, divs, etc.
• Control scrolling pace using predefined easing presets or custom Bezier curve points
• Ability to cancel scrolling with a callback function at any point

Installation

Getting started with Easy Scroll is simple. You can install it using npm or load it directly from a script tag.

• Install via npm: npm install easy-scroll --save
• Load via script tag: <script src="https://unpkg.com/easy-scroll"></script>

Importing the Library

Once you have installed Easy Scroll, you can import it easily based on your project setup:

• For ES6 modules: import easyScroll from 'easy-scroll';
• For CommonJS: var easyScroll = require('easy-scroll');
• For a global variable: The library will attach itself to window or this, depending on your environment.

API Configuration

Easy Scroll provides a function that accepts an object with several configuration options. Here’s a breakdown of the primary properties:

• scrollableDomEle (required): The DOM element you wish to scroll.
• direction (required): The scrolling direction – options are top, left, bottom, and right.
• duration (required): The duration of the scroll in milliseconds.
• easingPreset: Choose from a list of easing presets to control the scroll experience. Default is linear.
• cubicBezierPoints: Define custom Bezier curve points (x1, y1, x2, y2) for a bespoke scrolling experience.
• onRefUpdateCallback: A callback function executed at each scroll tick to allow for animation control.
• onAnimationCompleteCallback: A callback invoked upon completion of the scrolling.
• scrollAmount: The pixel amount to scroll; defaults to scrolling to the end if not specified.

Example Usage

Here is a simple usage example to demonstrate how Easy Scroll can be implemented:

import easyScroll from 'easy-scroll';

easyScroll({
    scrollableDomEle: window,
    direction: 'bottom',
    duration: 2000,
    easingPreset: 'easeInQuad',
    scrollAmount: 1000
});

Understanding the Scrolling Process: The Train Analogy

Think of an analogy involving a train on a track. The train represents the scrolling content, while the track represents the scrollable element. Just like a conductor would control the speed of the train as it moves forward (or backward) along the track, Easy Scroll gives you the ability to dictate the scrolling speed through various easing presets and durations. By specifying the amount of distance (in pixels) to be covered, you become the conductor of this scrolling journey!

Browser Support

Easy Scroll is supported on all modern browsers, making it versatile for a wide range of applications. For those working with older browsers, make sure to include polyfills for requestAnimationFrame and cancelAnimationFrame.

Troubleshooting

If you encounter issues while implementing Easy Scroll, consider these troubleshooting steps:

• Ensure your environment supports the module format you are using (ES6, CommonJS).
• Check if the specified scrollableDomEle is correctly defined and accessible in the DOM.
• Verify your direction input is valid and matches the supported directions.
• If animations aren’t working smoothly, try adjusting the duration and easingPreset.
• If you have other scripts affecting the scrollable element’s behavior, ensure they are not conflicting with Easy Scroll.
