Hwc Stimulus Fundamentals

This is your Stimulus controller workhorse when you're focused on the framework itself rather than a specific domain like forms or navigation. It walks you through lifecycle hooks, value callbacks, targets, outlets, action parameters, and keyboard event filters with enough guardrails to keep controllers composable and idempotent across connect/disconnect cycles. The references cover practical patterns like MutationObserver sorting, Web Share API integration, and target callback orchestration. It's opinionated about declarative action parameters over manual dataset parsing and knows when to escalate to neighbor skills for form validation, Turbo navigation, or real-time streaming concerns. If you're building a non-trivial Stimulus controller and need the API details at hand, this is the one to reach for.
