@TimoGlastra @genaris Not ready for review. Just a FYI this exists and is a WIP.

[genaris]

This is great @jleach ! Looking forward to have it merged so we can add our message pickup packages.

I have a question regarding the pnpm lock file. Otherwise it LGTM!

[genaris]

Since node 20 is under maintenance now, do you think we can upgrade to node:22? I'm not aware of any particular issue with it (or at least no more than the ones we had with 20 😅 )

[jleach]

Fixed.

How is this pnpm lock file generated? I mean, if I go to the root of the project and execute pnpm install, it will generate/update root's pnpm-lock.yaml, but it won't touch anything under apps/*.

Is this a manual copy of the one at the root? If so, could this copy be done using a script and gitignoring it in order to reduce the possibility of mismatching copies?

[jleach]

It's not meant to be there. Works like yarn in that it should only live at the root. I must have copied it while trying to figure out how to do Docker builds with workspaces, one lock file, and pnpm's linking.

Fixed.
