What's Pointeract?
Pointeract is a tiny JavaScript/TypeScript utility library focusing on one thing - handling user interactions with DOM elements, e.g. multitouch and touchpad.
With the unique strength of versatile typings in TypeScript and its dynamic nature, Pointeract have achieved a highly modular, extendable and efficient architecture. Its core bundle size is only 1KB minified + gzipped, functionalities come from also byte-sized modules. It's fully tree-shakable, the fewer modules you use, the smaller your bundle is.
To use it, one only needs to bind a DOM element and load some modules, and it will start monitoring user interactions and dispatch consumable events like pan and zoom.
Advantages
- 🐣 Tiny: With base 1KB minified and gzipped, 1-2KB for normal usage.
- 🦾 Robust: Excels at complex gestures where most interaction libraries fail, Why?
- 🧩 Extensible: Extend Pointeract effortlessly via our module API.
- 🔌 Flexible during Runtime: Options are updated reactively. Stop/start any module during runtime.
- 🛡️ Safe: Not modifying the DOM (except the
PreventDefaultmodule). Meticulous clean up prevents memory leaks.
Currently Supported Features
- Click (Double Click, Triple Click, Quadruple Click, Any Click)
- Drag
- Pan and Zoom via Mouse Wheel (
ctrl/shiftkey binding, touchpad support) - Pan and Zoom via Multitouch (Pan, Pinch)
- One-line Prevent Default
- Smooth Everything (drag / pan / zoom / any interaction involving numbers)
Those interactions are shipped via modules, which can be composed from a single drag-and-drop to a canvas app.

How Pointeract Stands Out?
There're already plenty of interaction libraries out there, most famous ones are Interact.js and Hammer.js, but Pointeract is different.
