bun is part of the node provider, and bun will automatically be detected when you have (and only have) a bun lock file

it's also a good practice to use a bun binary for it

check the build command on this repo:
https://github.com/kadumedim/bun-hono/blob/main/package.json

I'm using a monorepo so the bun lock file is not on the root dir, was it supposed to be detected?

yeah it wouldn't detect it then, shared or isolated?

I don't get what you mean, My project is a pnpm workspace, and I'm introducing a new service separately from this work space that is planned to run with bun.

Our structure is like this:

root
  - packages
    - node service1
        - package.json
    - node service2
        - package.json
    - new bun service
        - package.json
        - bun.lockb
  - package.json

does the new bun service import stuff from other packages?

For now no

Then it's an isolated monorepo

shared monorepo**

lol

I'm not sure, for this specific service , it's completely isolated from the others, I will try o follow the guide

!g I change the project structure to a bun monorepo, I still don't get the bun option
