Pros of scroller

• More actively maintained with recent updates
• Supports both vertical and horizontal scrolling
• Includes advanced features like zooming and snapping

Cons of scroller

• Larger file size and potentially more complex implementation
• May have a steeper learning curve for beginners

Code Comparison

scrollability:

scrollability.init();
el.addEventListener('scrollabilitystart', handleStart);
el.addEventListener('scrollabilityend', handleEnd);

scroller:

var scroller = new Scroller(render, {
  scrollingX: false,
  scrollingY: true,
  animating: true,
  bouncing: true
});
scroller.setDimensions(clientWidth, clientHeight, contentWidth, contentHeight);

Key Differences

• scrollability focuses on iOS-like scrolling behavior, while scroller offers more customization options
• scroller provides a more comprehensive API for controlling scroll behavior
• scrollability uses a simpler event-based system, whereas scroller requires more setup but offers finer control

Use Cases

• Choose scrollability for quick implementation of iOS-style scrolling
• Opt for scroller when you need advanced features like zooming or custom easing functions

Pros of iScroll

• More actively maintained with regular updates
• Supports a wider range of devices and browsers
• Offers additional features like zoom and snap functionality

Cons of iScroll

• Larger file size, which may impact performance on slower devices
• More complex configuration options, potentially steeper learning curve
• Some users report occasional jittery scrolling on certain devices

Code Comparison

iScroll:

var myScroll = new IScroll('#wrapper', {
    scrollX: true,
    scrollY: true,
    mouseWheel: true,
    wheelAction: 'zoom'
});

Scrollability:

scrollability.enableTouchScrolling(element);
scrollability.enableMouseWheelScrolling(element);

Both libraries aim to provide smooth scrolling experiences, especially on mobile devices. iScroll offers more features and customization options, while Scrollability focuses on simplicity and ease of use. iScroll is more suitable for complex projects with diverse requirements, whereas Scrollability might be preferable for simpler implementations or projects prioritizing lightweight solutions.

The code comparison shows that iScroll requires more initial setup but offers more configuration options out of the box. Scrollability, on the other hand, provides a more straightforward API with separate methods for enabling touch and mouse wheel scrolling.

Pros of ftscroller

• More actively maintained with recent updates
• Supports both touch and mouse input
• Offers smoother scrolling performance on mobile devices

Cons of ftscroller

• Larger file size and more complex codebase
• Steeper learning curve for implementation
• May have compatibility issues with older browsers

Code Comparison

ftscroller:

var scroller = new FTScroller(element, {
    scrollingX: true,
    scrollingY: true,
    bouncing: true,
    scrollbars: true
});

scrollability:

scrollability.init();
scrollability.enableTouchScrolling(element);

Key Differences

• ftscroller offers more configuration options out of the box
• scrollability has a simpler API and is easier to implement quickly
• ftscroller provides better cross-platform support
• scrollability is lighter weight and may be more suitable for simpler projects

Use Cases

• Choose ftscroller for complex, feature-rich applications requiring advanced scrolling functionality
• Opt for scrollability when building lightweight mobile web apps with basic scrolling needs

Community and Support

• ftscroller has a larger user base and more community contributions
• scrollability has fewer recent updates but may still be suitable for specific use cases

Pros of Sly

• Sly provides a more comprehensive set of features, including support for horizontal scrolling, nested scrolling, and custom scrolling behaviors.
• Sly has a larger community and more active development, with more contributors and more frequent updates.
• Sly offers a more flexible and customizable API, allowing developers to easily integrate it into their projects.

Cons of Sly

• Sly has a larger codebase and may be more complex to set up and configure, especially for simpler use cases.
• Sly may have a steeper learning curve compared to Scrollability, as it offers more advanced features and options.
• Sly may have a larger file size and dependency footprint, which could be a concern for projects with strict performance requirements.

Code Comparison

Scrollability:

var scroller = new Scrollability(element, {
  scrollX: true,
  scrollY: true,
  momentum: true,
  bouncing: true,
  zooming: true
});

Sly:

var sly = new Sly(frame, {
  horizontal: 1,
  itemNav: 'basic',
  smart: 1,
  activateOn: 'click',
  mouseDragging: 1,
  touchDragging: 1,
  releaseSwing: 1,
  startAt: 0,
  scrollBy: 1,
  speed: 300,
  elasticBounds: 1,
  easing: 'easeOutExpo',
  dragHandle: 1,
  dynamicHandle: 1,
  clickBar: 1,
  scrollSource: null,
  scrollTarget: null,
  scrollBy: {
    y: 0,
    x: 0
  }
});

Pros of skrollr

• More comprehensive and feature-rich, offering advanced parallax scrolling effects
• Supports both desktop and mobile devices
• Actively maintained with a larger community and more frequent updates

Cons of skrollr

• Steeper learning curve due to its extensive features and options
• Potentially heavier performance impact on complex animations
• Requires more setup and configuration for basic use cases

Code Comparison

skrollr:

var s = skrollr.init();

<div data-0="background-color:rgb(0,0,255);" data-500="background-color:rgb(255,0,0);">
    This element will gradually change from blue to red between 0-500px
</div>

scrollability:

Scrollability.enable(document.querySelector('#scroller'));

<div id="scroller">
    <div class="content">Scrollable content here</div>
</div>

Summary

skrollr offers more advanced features and wider device support, making it suitable for complex parallax scrolling effects. However, it may be overkill for simpler projects and has a steeper learning curve. scrollability, on the other hand, provides a more straightforward approach to basic scrolling functionality but lacks the advanced features and active maintenance of skrollr. The choice between the two depends on the specific project requirements and the desired level of scrolling complexity.
