event

Event API for event-driven programming.

#Installation

Add to your moon.pkg.json:

{
  "import": [
    "mizchi/js",
    "mizchi/js/web/event"
  ]
}

#Overview

Provides bindings for the Event API, including Event, CustomEvent, and MessageEvent.

#Usage Example

fn main {
  // Create a custom event
  let event = @event.CustomEvent::new("myevent")

  // Create event with detail
  let detail_event = @event.CustomEvent::new_with_detail("myevent", "detail data")

  // Create a message event
  let msg_event = @event.MessageEvent::new("message")

  // Event properties
  let event_type = event.type_()
  let bubbles = event.bubbles()
  let cancelable = event.cancelable()
}

#Available Types

Event - Base event type
CustomEvent - Events with custom data
MessageEvent - Events for message passing
EventTarget - Event listener registration
