Understanding Phoenix LiveView as an Elixir Process

Source: fly.io

The article by Jason Stiebs provides insight into how Phoenix LiveView leverages the Elixir language's underlying processes. Unlike traditional operating system processes or threads, Elixir processes—or 'green threads'—run within the Erlang Virtual Machine, which manages them efficiently to handle concurrent or parallel operations. Each process is extremely lightweight, requiring minimal memory and start-up time. In the context of Phoenix LiveView, every user interaction is managed by a separate Elixir process, maintaining a responsive and scalable system. LiveView’s design is informed by the principles of these processes; as a result, lifecycle functions like handle_event and handle_params must be executed swiftly to prevent user experience issues. The concept that each user has their own process is powerful but not problematic due to their lightweight nature. This article not only emphasizes the importance of process management for efficient web applications but also reinforces LiveView's distinction in frontend development, thanks to the robust and fault-tolerant concurrency model provided by Elixir and the Erlang VM.
