SolidStart issues with bun and vite building

[itsyoboieltr]

What version of Bun is running?

1.0.15+b3bdf22eb

What platform is your computer?

Darwin 23.1.0 arm64 arm

What steps can reproduce the bug?

The bug came up as I was developing my bun-based stack, called DBEST (DrizzleORM, Bun, ElysiaJS, SolidStart, Tailwind CSS). I made a reproduction branch available here: reprod

Steps:

1. Clone repo, switch to reprod branch, which is a minimal reprod based on the original branch.
2. bun i
3. bun run build:node

• This should behave as expected, producing a production build.

4. bun run build:bun

• Errors, and hangs forever.

What is the expected behavior?

Interesting observation: this only happens if ssr: false in vite.config.ts. If the default options are used, it builds.

It'll be interesting to see how the upcoming SolidStart release (Vite 5, Nitro, Vinxi) will fare with bun.

Can anyone please check here and tell me the problem or can you help me fix it. It is giving the error [bun] Warning: worker_threads.Worker option "execArgv" is not implemented.
