In this hackathon you get to build a simple chat application that follows the pub/sub methodology. You can use Firebase or any other database of your liking. The backend for the website should be preferably in firebase functions or node.js with JS(JavaScript). The application is supposed to process real-time requests, concurrently from atleast 500 users. The front-end should be a web app built with Angular that support text and if possible images(bonus points) as input. Web design is not to be considered in judging stage, we'd love to see you build awesome apps, not UIs :)
