Slack App Framework for Cloudflare Workers

library 1.3.9 ·javascript
verified Jun 17, 2026

slack-cloudflare-workers is an opinionated framework for building Slack applications designed specifically for Cloudflare Workers, leveraging their serverless environment. Inspired by Slack's popular Bolt framework but not strictly following its blueprint, it distinguishes itself with a strong TypeScript focus, built-in lazy listener capabilities (similar to bolt-python), and a commitment to zero additional runtime dependencies beyond its foundational `slack-edge` module. The current stable version is 1.3.9. This library caters to developers seeking highly performant, type-safe, and lightweight Slack integrations on the Cloudflare Workers platform, providing a streamlined experience compared to general-purpose Node.js frameworks. While release cadence isn't explicitly stated, the active development and frequent updates to the `slack-edge` ecosystem suggest a responsive maintenance schedule.
