Week 6: Real-time web applications

Explore how to enable real-time capabilities in web applications, including text, audio, video, and screen sharing. Learn to handle real-time updates from third-party services effectively using webhooks.

In this lecture, we will learn:

Why...

  • Do we need real-time features in web applications?
  • Are Websockets a better choice than classic methods like long-polling?
  • Are webhooks important for implementing real-time features from third-party services?
  • Do we need to use different strategies when scaling up the number of users with WebRTC?

How to...

  • Use Websockets for two-way communication between client and server
  • Use Server Sent Events (SSE) for one-way communication from server to client
  • Receive and process webhooks from third-party services using best practices
