LiveView's Lifecycle Hooks

Notes

Ever want to handle a LiveView action (event, message, patch, etc.) across several LiveViews without having to duplicate the code?

LiveView’s attach_hook/4 helper is the thing for you!

It allows us to tap into these lifecycle stages:

• handle_event,
• handle_params,
• handle_info, and
• after_render

That can be helpful, especially when you consider LiveView’s unique security model.
