What is DragDoll?

DragDoll is a modular and highly extensible drag and drop system written in TypeScript. Originally based on Muuri's internal drag system, it has been fully redesigned to serve as a general-purpose drag and drop system.

At its core, DragDoll is built on the concept of sensors, which are responsible for listening to user input events (or any events, for that matter) and emitting drag events based on those inputs. While DragDoll comes with a few built-in sensors, you can also create your own to listen to any kind of input events you desire.

To actually move elements around, DragDoll provides the Draggable class. This class acts as an orchestrator for any number of sensors and moves DOM elements based on the drag events emitted by the provided sensors. The Draggable class features a simple and functional API that allows you to control the drag process explicitly from start to finish.

For complete drag and drop experiences, DragDoll also provides DndContext and Droppable classes, which handle collision detection between draggable elements and drop targets. Together, these three classes create a powerful foundation for building sophisticated drag and drop interfaces.

Features

📡   Sweet Sensors: A well-documented and extendable Sensor system that normalizes any input into unified drag events, giving you complete control over user interactions.

🤏   Dynamic Draggables: A highly customizable and pluggable Draggable system with autoscrolling superpowers, making complex drag-and-drop scenarios effortless.

🎯   Precise Collisions: Advanced collision detection system that efficiently determines drop targets and provides rich interaction data for creating intuitive drag and drop experiences.

🪄   Magical Transforms: Finally, transformed (2D) elements can be dragged normally. Rotate, scale, skew, and translate to your heart's content without limitations.

🧘   Blissful DX: Experience a seamless developer experience with strong typing, smart defaults, and pre-baked solutions for common use cases.

🍦   Vanilla Flavour: No frameworks were abused while writing this library. It's all vanilla framework-free TypeScript down to the core.

💝   Free & Open Source: 100% MIT licensed, spread the love.

Roadmap

• Utilizing Native Drag and Drop: By not using the native HTML Drag and Drop API, DragDoll misses out on crucial features like file drag-and-drop and dragging items between different windows. It's still a bit unclear how to integrate the native API with DragDoll in a clear and ergonomic way, but figuring this out is a high priority for us.

• Support for other Frameworks: Expect support for frontend frameworks like React, Vue, Svelte, etc. in the future.
