How to use @tryghost/kg-parser-plugins - 2 common examples

module.exports.toMobiledoc = (html, options = {}) => {
    // 1. sanitize HTML
    // @TODO: what sanitisations are needed?
    let sanitizedHTML = html;

    // 2. Do something vaguely like loadPost
    // https://github.com/ErisDS/mobiledoc-kit/blob/master/src/js/editor/editor.js#L193

    // 2.a. Parse our HTML and convert to a DOM with same API as browser
    let dom = new JSDOM(`${sanitizedHTML}`);

    // 2.b. Use Mobiledoc-kit's own DOM Parser to convert the DOM into mobiledoc's internal format
    // We use our parser plugins by default, but this is extensible
    if (!options.plugins) {
        options.plugins = createParserPlugins({
            createDocument(html) {
                return (new JSDOM(html)).window.document;
            }
        });
    }
    let parser = new DOMParser(new Builder(), options);
    let post = parser.parse(dom.window.document.body);

    // 3. Do something vaguely like serializePost, to render the mobiledoc internal format as mobiledoc
    // https://github.com/ErisDS/mobiledoc-kit/blob/master/src/js/editor/editor.js#L567
    let mobiledoc = mobiledocRenderer.render(post, '0.3.1');

    return mobiledoc;
};

// trigger the willCreateEditor closure action
        this.willCreateEditor();

        // teardown any old editor that might be around
        let editor = this.editor;
        if (editor) {
            editor.destroy();
        }

        // create a new editor
        let editorOptions = this.editorOptions;
        editorOptions.mobiledoc = mobiledoc;
        editorOptions.showLinkTooltips = false;
        editorOptions.undoDepth = UNDO_DEPTH;
        editorOptions.parserPlugins = createParserPlugins();

        let componentHooks = {
            // triggered when a card section is added to the mobiledoc
            [ADD_CARD_HOOK]: ({env, options, payload}, koenigOptions) => {
                let cardName = env.name;
                let componentName = CARD_COMPONENT_MAP[cardName];

                // the payload must be copied to avoid sharing the reference
                // `payload.files` is special because it's set by paste/drag-n-drop
                // events and can't be copied for security reasons
                let {files} = payload;
                let payloadCopy = JSON.parse(JSON.stringify(payload || null));
                payloadCopy.files = files;

                // all of the properties that will be passed through to the
                // component cards via the template
