LiveView Course Update #4: Live Components and Real-Time Updates
March 15, 2023
Today we added 2 new modules (3 videos) to our Phoenix LiveView course on designing Live Components and using Phoenix PubSub to broadcast real-time updates to multiple LiveViews. 📡
Live Components
In addition to function (stateless) components, LiveView also has live (stateful) components. They have their own state, handle their own events, and render independent of their parent LiveView. We build a live component step-by-step so you understand how they work, when and why to use them, and how they communicate with their parent LiveView.
Real-Time Updates
You don’t have to jump through a bunch of hoops to update LiveViews in real-time across multiple browser sessions. Phoenix PubSub makes it super easy to broadcast messages from the server to multiple LiveViews. To cap off the volunteers project, we use PubSub to keep everything in sync!
