Publisher

Installation: If not already installed, add the package with pnpm add @efesto-cloud/publisher.

Use this skill when you need event broadcasting without stored state.

Quick Rule

• Publisher: emit events with notify(...) to current subscribers.
• No state: if you need get/set, use Observable instead.

Procedure

1. Create new PublisherImpl<Args>() with typed tuple args.
2. Register listeners with subscribe(...) and keep the cleanup function.
3. Emit events via notify(...) and cleanup with returned unsubscribe or unsubscribeAll().

Common Mistakes

• Using Publisher as a state container.
• Ignoring returned unsubscribe function.
• Emitting args that do not match the tuple type.
