# What is SnapSort?

SnapSort is a drag-and-drop interface library for the web.
A core concept of SnapSort is to provide _utilities_ for
making drag-and-drop, not pre-built components.
Specifically, this library is built on two key principles:
- **Primitives over abstraction**: Rather than abstracting core utilities inside APIs, expose them directly. Let developers mix and match for maximum flexibility.
- **Everything is configurable**: Avoid "sensible defaults" because there is no such thing. Every UI is unique.

For developers, this means:
  - You only need to know two components: `Item` and `Container`. Every UI are derived from these primitives.
  - Extensive hooks to define custom behavior.
  - Wide array of configurations to customize drag and drop behavior, animations, etc.
  - Style-less by default, bring your own CSS.

Start with <a href="/docs/snapsort/llms.txt" data-sveltekit-reload>SnapSort's <code>llms.txt</code></a> for the complete documentation tree, or append `.md` to any documentation URL to get clean, framework-aware Markdown. For example, open <a href="/docs/snapsort/introduction.md" data-sveltekit-reload>this page as Markdown</a>.

> [!WARNING]
> SnapSort is in early beta. Expect breaking API changes, incomplete features, and behavioral instability between releases. It is not yet recommended for production-critical interfaces.
>
> SnapSort currently targets pointer-based interactions. Keyboard controls and other accessibility features have not been implemented yet.
