Yesterday, I migrated my web worker codes from Comlink to CapnWeb. I had extensive experience with Cloudflare Worker bindings, and as mentioned in the original post, they were quite similar.

Everything appears to be functioning smoothly, but I do miss the ‘transfer’ feature in Comlink. Although it wasn’t a critical feature, it was a nice one.

The best aspect of CapnWeb is that we can reuse most of the code related to clients, servers, and web workers (including Cloudflare Workers).
