Discussion on: How can I get rendered innerHTML that includes Shadow DOM?

I’m building a tool that parses the page HTML and does static checking for accessibility, SEO, etc. Right now it’s only getting the light DOM, no shadow DOM. So if there is a top level web component which has many nested web components inside its shadow root, none of the shadow DOM elements will be there. So I need an alternative that gets the shadow DOM children instead and returns a string of rendered HTML.

Make sense? 😅

Makes sense. Though now it depends on how you are getting the HTML page which has all the webcomponents.

ShadowDOM exists in DOM, so if it is a scraped page, shadowRoot will not have any elements inside it.

Another fact to consider is that web components with shadowDOM might be created with closed mode; in that case, you can not access the inner DOM of shadowDOM.
