ChannelRegistry

Defined in: packages/postal/src/channel.ts:42

Augmentable interface for global channel type registration.

Users can declare their channel maps once via module augmentation and get automatic payload inference on getChannel() without passing a generic at every call site:

declare module 'postal' {
  interface ChannelRegistry {
    orders: { 'item.placed': { sku: string } };
  }
}

const orders = getChannel('orders'); // Channel<{ 'item.placed': { sku: string } }>

Channels not in the registry fall back to Record<string, unknown> (untyped).
