Cannot use Cloudflare Durable Objects with Hono and Vite #190

Open jhlabs opened 6 days ago

jhlabs commented 6 days ago

I am trying to setup Hono with Vite and Cloudflare Durable Objects. I have cloned the Durable Objects example and added the Vite Dev Server from this repository according to the instructions. Here is a repository for this setup https://github.com/jhlabs/hono-vite-durable-objects.

When I run vite to start the dev server (same is true for build with vite) I get the following error:

[vite] Pre-transform error: Failed to load url cloudflare:workers (resolved id: cloudflare:workers) in /Users/johannes/dev/hono-vite-durable-objects/src/counter.ts. Does the file exist?

I suspect that the cloudflare:workers import should be excluded from being bundled by vite, as this is later resolved by the wrangler runtime. However, I could not get this to work and would expect this Vite Plugin to support this feature out of the box.

Thanks for your help in resolving this!
