Build custom Slack runtimes
By Steven Van ·
Chat SDK's Slack adapter now offers webhook, format, API and Block Kit helpers as separate imports for custom runtimes.
Vercel's Chat SDK now exposes the Slack adapter's internals as standalone imports, for apps that already handle their own routing, state, or workflow execution rather than using the full Chat runtime.
- Request verification and payload parsing (@chat-adapter/slack/webhook)
- Markdown formatting (@chat-adapter/slack/format)
- Fetch-based Web API calls (@chat-adapter/slack/api)
- Block Kit conversion (@chat-adapter/slack/blocks)
Each subpath skips the full Chat runtime, so imports stay limited to what's used. Details are in the Slack primitives documentation.
