Responding to Global Broadcasts in Phoenix LiveView Apps

Andrew Timberlake explains a method for responding to channel broadcasts in a global manner within a Phoenix LiveView application. He describes the challenge of updating a global state, such as a message counter, across all LiveView instances. The article outlines various approaches and ultimately provides a solution using Elixir's macro tools and the `@before_compile` attribute to ensure global subscription handling without hindering individual LiveView subscriptions. It includes code examples and discusses the implications of different strategies such as using LiveComponents and live sessions.
