• HSON (Hypertext Structured Object Notation) is a 'glue format'. Its node graph models JSON values and HTML documents in a common tree representation, and its serialized syntax can express both. HTML can be represented as JSON data, and JSON can be represented as markup. -> Uniting two non-interchangeable building blocks of the web suggests new ways of building web content. This is the key insight that powers hson-live.

• hson-live is a TypeScript library built to realize HSON. It has two core components:

- hson.transform converts JSON and HTML to and from HSON. The 7-step transformer circuit is stable under repeated round trips: after canonicalization, data does not drift across repeated loops. hson-live provides a circuit test diagnostic to verify the parser chain. hson-live supports JSON, HTML/XML, SVG, and HSON.

- hson.liveTree is a web-authoring surface built on this operation. At runtime, LiveTree: 1. parses document.body and nested content to a HSON node graph 2. maintains a DOM projection of that graph 3. provides an interface for editing and manipulation

LiveTree offers a vision of markup + styling + data in a single source of truth, unified in a low-friction typed ecosystem. LiveTree's API includes: - traversal, creation, and manipulation of the underlying HSON graph with synchronous DOM updates - EventListener management with automated teardown - SVG creation and animation - <canvas> support - scoped CSS, keyframes, animation, and @property - ergonomic attribute management

LiveDemo, the first website made entirely in hson-live, can be found at

hson.terminalgothic.com

LiveDemo features 1000+ tests, interactive demos highlighting various functionalities, as well as the readme and other documentation.

hson-live is in very early stages still.

(Disclaimer: I am not a developer but an enthusiastic hobbyist; this is my first library. Please be gentle.)
