Custom Slack transport

Inject a SlackTransport when another layer owns Socket Mode or when tests need a fake transport. See @anvia/slack for standard setup.

Inject a transport

import { SlackChannel } from '@anvia/slack'

const channel = new SlackChannel({ transport: existingSlackTransport })

The transport must parse and validate external payloads into SlackSocketEvent values (use parseSlackSocketEvent(), parseSlackSocketInteraction(), and parseSlackSocketCommand() — without the last, slash commands are silently dropped), acknowledge Slack envelopes promptly, implement the start/stop lifecycle plus the Web API operations (send, edit, delete, react, removeReaction, loadAttachment), and drain active handlers during shutdown. SlackSocketTransport is a reference implementation.

Shutdown

await channel.stop()

Stopping detaches listeners, disconnects Socket Mode, and waits for in-flight deliveries. Stop the channel agent service instead when it owns the channel.
