NoUiSlider
noUiSlider is a dependency-free JavaScript range slider library that provides a lightweight, ARIA-accessible slider widget with multi-touch and keyboard support. It is built as a standalone implementation with no external dependencies, using GPU compositing for smooth animations and responsive layout adaptation across different screen sizes.
The library distinguishes itself through its comprehensive accessibility and input handling, offering full keyboard navigation for slider control without requiring a mouse, along with multi-touch support for simultaneous handle manipulation on mobile and desktop devices. It includes a CSS-only theming system for visual customization, non-linear range mapping for logarithmic or custom scale distributions, and constraint-based handle management that enforces minimum and maximum spacing between multiple handles.
Additional capabilities include event-driven value binding to synchronize slider state with HTML inputs, responsive layout adaptation using a resize observer, and support for tooltips, pips, and value display along the slider track. The library also provides features for snapping to allowed values, clamping within soft limits, and merging overlapping tooltips when handles are close together.

- Slider Range Segmentations - Divides the slider range into segments with different step sizes for logarithmic or custom scales.
- Slider GPU Animations - Uses GPU compositing for smooth slider animations without layout reflows.
- Non-Linear Track Configurators - Maps slider positions to non-uniform value intervals for logarithmic or custom scale distributions.
- GPU-Accelerated UI Rendering - Uses GPU compositing to render slider movements smoothly without layout recalculations.
- Slider Value Tooltips - Shows tooltips on handles and a scale of tick marks along the slider track for reference.
- GPU Compositing - Renders slider movements using GPU compositing to avoid layout recalculations and maintain smooth performance.
- Slider State Bindings - Binds slider state to external inputs and tooltips through custom events without polling.
- Component-Scoped CSS Themes - Styles slider tracks, handles, and connect elements entirely through CSS classes for full visual customization.
- Value Snapping Utilities - Restricts the slider to snap only to defined range values, skipping intermediate positions.
- Pip Jumping - Provides a clickable pip scale that jumps the slider handle to the selected value.
- Slider Range Mappings - Maps slider positions to arbitrary value intervals enabling logarithmic or custom scale distributions.
- Multi-Touch Interaction Handling - Handles simultaneous touch points for two-handle slider manipulation on mobile devices.
- Slider Orientation Controls - Provides orientation controls for rotating sliders between horizontal and vertical layouts.
- Unified Input Abstraction Layers - Abstracts pointer, touch, and keyboard events into a unified model supporting multi-touch manipulation.
- Keyboard-Triggered Value Steps - Allows stepping through slider values one at a time via keyboard arrow key presses.
- Handle Distance Constraints - Sets minimum and maximum distances between handles to prevent overlapping or excessive separation.
- Segmented - Divides the slider range into segments with different step sizes for uneven value distribution.
- Responsive Sliders - Automatically resizes and repositions the slider to fit different screen sizes and container widths.
- Responsive Layout Adapters - Automatically resizes and repositions the slider to fit different container widths.
- Slider Styling Hooks - Provides CSS class hooks for customizing slider track and handle appearance.
