Presets and Options

When initializing an MarkdownExit instance, you can pass options or presets to it for customization.

markdown-exit offers various presets to customize the Markdown parsing and rendering behavior.

// default
const md = createMarkdownExit()

const md = createMarkdownExit('commonmark')

For more granular control, you can provide specific options:

const md = createMarkdownExit({
  // Enable HTML tags in source

  // and more ...
})

For all available options, please refer to the MarkdownExitOptions documentation.
