message

MessageChannel API for two-way communication between contexts.

#Installation

Add to your moon.pkg.json:

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

#Overview

Provides bindings for MessageChannel and MessagePort for creating communication channels.

#Usage Example

fn main {
  // Create a message channel
  let channel = @message.MessageChannel::new()

  // Get the two ports
  let port1 = channel.port1()
  let port2 = channel.port2()

  // Set up message handler on port1
  port1.set_onmessage(fn(event) {
    @console.log("Port1 received:", event.data())
  })

  // Send message from port2 to port1
  port2.post_message("Hello from port2!")

  // Start receiving messages
  port1.start()
}

#Use Cases

Communication between main thread and workers
Iframe communication
Creating isolated communication channels

MessageChannel

source

#external
pub type MessageChannel

MessageChannel creates a new message channel and returns it with two MessagePort objects https://developer.mozilla.org/en-US/docs/Web/API/MessageChannel

MessageEvent

source

pub(all) struct MessageEvent {
  data : @mizchi/js/core.Any
Any
  origin : String
  lastEventId : String
  ports : Array[MessagePort]
}

MessageEvent represents a message received by a target object https://developer.mozilla.org/en-US/docs/Web/API/MessageEvent

#
MessagePort

source

#external
pub type MessagePort

MessagePort represents one end of a message channel https://developer.mozilla.org/en-US/docs/Web/API/MessagePort

MessagePort implements the EventTarget trait for event handling.
