What problem does it solve?

LiveView development often faces challenges around structuring the lifecycle, keeping renders efficient, and implementing scalable real-time updates. This guide provides a concise set of patterns and best practices to build responsive, interactive LiveView features with robust state management, streaming updates, and safe event handling.

Core Features & Use Cases

• Lifecycle optimization: minimal mount, use handle_params for URL-driven state, and avoid blocking operations.
• Streams & real-time updates: use streams for lists and incremental updates, with phx-update="stream" and proper DOM IDs.
• Events, PubSub, and forms: validate input server-side, manage PubSub subscriptions, and build robust forms with to_form and validations.
• Performance & components: use temporary assigns, debouncing, and offload long-running tasks to async operations.

Quick Start
