How do I test my Workers using Bun?

You can use the native 'bun:test' runner for unit testing your logic. For integration testing, this skill provides patterns to use Miniflare with Bun to simulate the Cloudflare environment.

How does this skill handle database migrations for D1?

The skill provides patterns for configuring wrangler.toml and using the Wrangler CLI within the Bun environment to manage D1 database bindings and migrations.

Can I use Bun-specific APIs like Bun.file() in Cloudflare Workers?

No, Cloudflare Workers run on the V8-based Workerd runtime, which supports Web APIs. You must use the 'browser' build target and avoid Bun-exclusive APIs while using Bun as your local bundler.

Does this skill support the Hono framework?

Yes, it includes specific implementation guides for building robust, type-safe APIs on Cloudflare Workers using the Hono framework and Bun.
