A tagged template literal that allows safe interpolation of values into HTML, following the HTML5 spec

Overview

Hypertext Literal is a tagged template literal designed for HTML content interpolation. It allows for automatic escaping and the interpolation of non-serializable values such as event listeners and style objects. This open-source tool under the ISC license is lightweight, with no dependencies, and easily accessible on npm.

Features

  • Tagged Template Literal for HTML: Renders markup as an element, text node, or null as appropriate.
  • Automatic Escaping: Interpolated values in attributes or data are escaped to maintain surrounding markup structure.
  • Styles Interpolation: Safely interpolate into style properties by specifying the style attribute as an object literal.
  • Function Attributes: Function attribute values are assigned as properties for registering event listeners.
  • Boolean Attributes Handling: False attribute values are treated as if not specified, while true values are equivalent to an empty string.
  • Optional Values: Null or undefined attribute values are considered as if the attribute hadn't been specified.
