A few weeks back Vaadin organized a Progressive Web App programming competition, giving the winners a chance to attend Google Progressive Web App Developer Summit in Amsterdam.
In this month’s Community Spotlight, we want to introduce the winners of the competition and showcase the cool projects they did. Both teams created impressive apps that show how PWA technologies can be used to create apps that work well, even in poor network conditions, and integrate with the operating system.
Aarthi and Anand
Aarthi Narayanan and Anand Aravindan are both developers living in Chicago. For their project, they built an impressive real time stock screening app, https://realtimestockscreener.com
The app was built using Polymer, Redis, Nodejs and RethinkDB. You can find the source code on GitHub, if you’re interested in looking into how it was built: https://github.com/anandanand84/pwa-competition
Abdón and Ismael
The second winning team came from Spain. Abdón Rodríguez Davila and Ismael Faro Sertague are both active in the Spanish GDG. For their winning project, they wrote a new GDG Spain site using Progressive Web App technologies. Their app is up on a staging server for some final tweaks before going live: https://gdg-es.appspot.com. I had the pleasure of meeting both Abdón and Ismael in Amsterdam for the PWA Developer Summit where we learned a lot about upcoming technologies and were able to talk with developers from Google and other browser vendors.
The GDG site is built using Polymer and Firebase, using the new Polymer App elements for firebase connectivity and IndexedDB caching.

The Vaadin team would like to congratulate both winning teams! If PWA got your attention, we have an upcoming webinar about it soon.
