@texmorph/mathjax

MathJax 4 (SVG output) renderer and the createMorph entry point. Re-exports the same @texmorph/dom members as @texmorph/katex.

createMorph

function createMorph(
  host: HTMLElement,
  from: FormulaInput,
  to: FormulaInput,
  options?: MathMorphOptions<SafeMathJaxOptions> & {
    renderer?: FormulaRenderer<SafeMathJaxOptions>;
    mathjax?: MathJaxRendererOptions;
  },
): Promise<MathMorph>;

Option	Description
renderer	A renderer from mathjaxRenderer(). Takes precedence over mathjax.
mathjax	Options for a new renderer created for this call.
(neither)	A shared default renderer is used.

All other options are MathMorphOptions.

mathjaxRenderer

function mathjaxRenderer(options?: MathJaxRendererOptions): FormulaRenderer<SafeMathJaxOptions>;

interface MathJaxRendererOptions {
  packages?: readonly string[];
  macros?: Readonly<Record<string, string | [string, number]>>;
  loadFont?: (range: string) => Promise<unknown>;
  preloadFonts?: readonly string[];
}

Option	Description
packages	TeX packages. Default ['base', 'ams', 'newcommand', 'color', 'cancel', 'boldsymbol']. Unregistered packages, and html, require or autoload, throw a TypeError.
macros	Macro definitions; [body, argumentCount] for macros with arguments.
loadFont	Loads one dynamic newcm font range by name (e.g. "latin-b"). Page-global.
preloadFonts	Ranges to load in ready().

The renderer provides stylesheet() (the mjx-container CSS) for shadow roots and honors AbortSignal in ready() and render().

SafeMathJaxOptions

interface SafeMathJaxOptions {
  containerWidth?: number; // CSS px for percentage widths; default 80ex
}

Pass it as rendererOptions.
