Building a realtime chat application using WebSockets with Angular and Firebase

This tutorial guides you through building a basic realtime chat application using WebSockets with Angular and Firebase. It covers setting up the Firebase app, connecting it to an Angular app, creating a chat type, configuring components, sending and retrieving messages, and adding a user interface. While Firebase can be useful for quickly getting an application live without worrying about backend implementation, it has limitations when it comes to scaling and ensuring message delivery guarantees. Alternative approaches include using open source tools like Apache Kafka or creating custom backends with serverless technologies.
