Introduction to Realtime Web Applications
With WebSockets and WebRTC! 🚀
About
Introduction to Realtime Web Applications is a workshop aimed at introducing to participants the principles behind building highly interactive and real-time web applications which has wide applicability.
Participants will pick up the basics of how to build realtime web applications through utilising WebSockets and WebRTC technologies to build applications such as text and video chat rooms, as well as get inspired to build similar applications themselves.
In addition, we also go through the basics of utilizing Docker and deploying the applications on Heroku, as well as other considerations on scalability and reliability.
This workshop was initially run as an Independent Activities Period (IAP) workshop at the Singapore University of Technology and Design. To encourage participants to produce cool realtime applications, we organised a hackathon towards the end of the workshop, and we saw many interesting projects! The winning submissions are included in the project list below. Feel free to try them out!
We're looking forward to hosting a second run of the workshop at FOSSASIA Summit 2021!
