 Hey there, folks. What's up? It's Rob Dodson. Welcome back to the Progressive Web App Summit. We're here in the Codelab area up on the third floor. I've got Eric Bidelman with me. Eric is the coolest developer advocate that I know. Eric, can you tell me just a little bit about what are the folks doing here? What kinds of Codelabs are people working on right now? What is going on here? So we're just coding, man. We're building Progressive Web Apps. There's a bunch of Codelabs for the event. You can build stuff in Polymer. You can build stuff and learn about Progressive Web Apps. And people are just sitting down, getting their hands dirty. It's great. Right on. So we've got Polymer, Progressive Web Apps, Firebase, Web Bluetooth, all sorts of cool, interesting, bleeding-edge stuff. Now, the Codelab site itself actually has kind of a cool architecture, which you touched on a little bit in your session. Can you talk through that just a little bit? What's up with that site? Yeah. So we built the site in-house, and we basically wanted to try to build a site that renders really fast and uses Polymer and Web components, as you probably know about Web components. But it's exciting because we were able to use things like Service Worker, use Polymer. In my talk, I actually go over kind of how we did it and got a really fast first paint, even on mobile. And it renders great. It feels great. And it hosts all of developer's Codelabs that we have. So it's cool. And if these folks want to go scope out that site and actually do some of these Codelabs, where do they go? So they go to codelabs.developers.google.com. And that actually hosts all of our Codelabs. So not just Web stuff, if you're interested in anything under the sun when it comes to our developer products, it's there. And they'll be available forever and ever more until the Internet dies. So we'll have a link to the Codelabs down in the description. Eric, thank you so much for being with me today. Thank you all so much for watching.

We've got all the sessions from today and yesterday from beautiful sunny Amsterdam. I'm Rob Dodson. And stay with us for more.
