v1.0.0

Major Changes

• 95c0f73: ultrahtml is a complete markup toolkit with a tiny footprint. Parse, transform, and render HTML on the server, in the browser, with or without a build step.

  Breaking Changes

  The signature of transform has been updated. Rather than applying sanitization and component swapping by default, these have been split out to individual ultrahtml/transformers that can be applied modularly.

  In [email protected], transform accepted an options object with sanitize and components. Other transformations would need to be applied outside of this flow.

  import { transform } from "ultrahtml";
  
  await transform(markup, {
    components: { h1: "h2" },
    sanitize: { allowElements: ["h1", "h2", "h3"] }
  });

  In [email protected], transform accepts an array of transformers to apply. The sanitize and components options can be handled with the built-in transformers named sanitize and swap.

  import { transform } from "ultrahtml";
  import swap from "ultrahtml/transformers/swap";
  import sanitize from "ultrahtml/transformers/sanitize";
  
  await transform(markup, [
    swap({ h1: "h2" }),
    sanitize({ allowElements: ["h1", "h2", "h3"] })
  ]);

  New Features

  JSX Runtime

  ultrahtml now comes with h and Fragment functions for JSX, as well as a jsx-runtime export.

  Tranformers

  Transformers are AST transformations that can be applied to any ultrahtml Node. Usually these are applied to entire documents.

  New inline transformer inlines CSS from <style> blocks directly to matching elements.

  New scope transformer scopes CSS from <style> blocks to the elements in a given document or component.
