Content that is dynamically loaded after page load

Hello,

I have a page whose source code is something like this:

When you load the page, app-root is empty. Then the script runs automatically and dynamically fetches content and populates app-root.

When I inspect the page with the developer tools, I see all the contents in the element tree. But when I click "view source", I see only the original empty page, and the scraper seems to work with that original empty page.

Is there any way of scraping a page like that? Thanks!

Best to submit your sitemap or examples if you want someone to take a look
