In the video we're going to make an open graph scraper which could potentially be created in just client-side code however most requests to access a web url would be blocked in the browser so we'll send a request for a URL from a Node.js back end.

The Node server will also parse our open graph data with XPath and reconstruct the data in to a JavaScript object which we can then send to the client as JSON data.

Our VanillaJS front-end will consume the response from our API endpoint and we'll display the open graph data using a simple front-end.

This might not be the kind of app that you create as a standalone project but there might be a need in a larger application to parse some data from an external web page and you can certainly use these principals of using an open graph scraper to get data from a web page into an object to be used in either your server side or client side code.
