Flack is one of the assignments given to learners of CS50’s Web Programming with Python and JavaScript in 2019. It was one of my earliest experiences with web development, which I think is pretty evident in the design of the app, as the logo and chat rooms are basically my best attempt at replicating Telegram.

Main takeaways

1. Creating a chat app that uses web sockets (Socket.IO) to achieve real-time communication between server and client. Seperate chat rooms were achieved by using Socket.IO rooms function.
2. Trying out a different front-end framework (Bulma) rather than just sticking with Bootstrap which I was familiar with.
3. Hosting my first production server on Heroku which allows other people to use the app I created!
