hyperHTML is a DOM template library and data-binding engine that uses tagged template literals to render and update elements. It functions as a web component framework and a virtual DOM alternative, linking JavaScript data directly to specific HTML elements to enable automatic page updates.
The project avoids the overhead of a virtual DOM by using a reconciliation process that updates only the changed parts of the real DOM. It includes a build-time HTML template minifier to compress content within template literals and reduce client-side data transfer.
The library covers a broad range of capabilities, including client-side rendering, component state encapsulation, and custom element rendering. It provides utilities for managing DOM node observation, event dispatching, and boolean attribute toggling.
