Custom adapter (bun) example not working

[arielweinberger]

Hey, is the custom adapter example ready?

Cloning the folder, installing packages, as well as missing @swc/core and @workflow/swc-plugin, and running bun run dev.

Getting the following error:

bun run dev

Quick update, I had to pin "@swc/core": "1.11.24" (saw this in your package lock file) and it's now working. Any plans to support more latest SWC versions, or update the example to include the missing packages in package.json + pin to the supported @swc/core version?

Update: The breaking change on SWC's side probably happened somewhere in 1.13.x or 1.14.x. The 1.12.x seems to work.

Thanks @arielweinberger. Likely not right now since swc version migrations are extremely tricky. Since the compiler works and isn't really a bottleneck, I don't think we'll bump swc core versions anytime soon unless there's a meaningful reason to like a reported security vulnerability

[pranaygp]

do we need to pin the swc version in the bun example via bun.lock?
