Sometimes there is a need to transform HTML just before generating the output in md-to-pdf, i.e. we need to convert images to Base64, sanitize links, add PagedJS, add some JavaScript.
Solution:
We achieved it by modifying a part of code in md-to-pdf like this:
let html = getHtml(md, config);
if (config.transform_html) {
html = await config.transform_html(html);
}
Where transform_html is a custom function, i.e.:
const { JSDOM } = require('jsdom');
const { window } = new JSDOM('<!DOCTYPE html>');
if (!config.req) throw new TypeError(`config.req not defined!`);
// NOTE: embeds images as base64
const embedImages = new EmbedHTMLImages({ req: config.req });
const sanitizedLinksHtml = replaceTextContentWithHref(
html,
window.DOMParser,
true
);
return await embedImages.run(sanitizedLinksHtml);
