ChannelLike type

Tiny BroadcastChannel-shaped abstraction. Lets tests inject a fake (a shared in-memory bus across multiple "tabs" in the same process) and keeps server safety in one place: outside a browser, and with nochannelFactory override, the plugin opens no channel and installs no hooks.

Signature:

type ChannelLike = {
  postMessage(data: unknown): void;
  addEventListener(type: 'message', listener: (event: {
    data: unknown;
  }) => void): void;
  removeEventListener(type: 'message', listener: (event: {
    data: unknown;
  }) => void): void;
  close(): void;
};
