Using LiveView for Real-Time User Interaction and Product Analytics

The talk emphasizes on how Elixir's LiveView has introduced a new way to build web applications with real-time features. Nouvellet discusses how BEAM's observability can be used beyond debugging, for inspecting user behavior and enhancing product development. By treating each user as a process, it becomes possible to monitor user activities in real-time and interact directly, for instance, listing root LiveView processes, viewing socket assigns, and sending live messages or polls to users. The speaker also explores building an internal admin interface for real-time interaction, showing the capability to track which users are online, their product interactions, and more. Additionally, Nouvellet introduces an open-source project named live room, which aims to deepen the interaction between builders and users through features like live cursors, broadcasting click events, focusing text inputs, etc. The speaker stresses on the importance of understanding user behavior to improve the product iteratively.
