Storybook Channel

Storybook Channel is similar to an EventEmitter. Channels are used with Storybook implementations to send/receive events between the Storybook Manager and the Storybook Renderer.

class Channel {
  addListener(type, listener) {}
  addPeerListener(type, listener) {} // ignore events from itself
  emit(type, ...args) {}
  eventNames() {}
  listenerCount(type) {}
  listeners(type) {}
  on(type, listener) {}
  once(type, listener) {}
  prependListener(type, listener) {}
  prependOnceListener(type, listener) {}
  removeAllListeners(type) {}
  removeListener(type, listener) {}
}

The channel takes a Transport object as a parameter which will be used to send/receive messages. The transport object should implement this interface.

class Transport {
  send(event) {}
  setHandler(handler) {}
}

eventemitter3

EventEmitter3 is a high-performance event emitter. While it provides similar event-driven communication capabilities, it does not include a transport layer for communication between different environments like @storybook/channels does.

mitt

Mitt is a tiny functional event emitter / pubsub. It offers similar event handling functionality but lacks the built-in transport layer for cross-environment communication that @storybook/channels provides.
