Skill: liveview-lifecycle

INVOKE BEFORE creating or changing LiveView modules, components, or uploads.

Use when

• Working in lib/*_web/live/ or lib/*_web/components/.
• Handling events, params, or uploads.

Checklist

• Mount: guard for connected?; load minimal assigns; defer heavy loads to handle_params.
• Handle params: use pattern matching on params; push_patch for navigation.
• Events: validate input; throttle noisy events; use PubSub for cross-process updates.
• Assigns: always use assign/3 or stream_insert; avoid direct map updates.
• Uploads: configure allow_upload with size limits; use consume_uploaded_entries.
• Navigation: prefer push_navigate for live redirects; redirect only when leaving LV.

Gotchas

• Avoid Repo calls in render/handle_info without rate-limiting.
• Ensure components use attr :id, :string where needed.
• Include static_paths/0 entries for assets referenced in hooks.
