Seems like Netlify officially supports Bun now: https://docs.netlify.com/configure-builds/manage-dependencies/#bun. Would like to see this get merged and have a modernized workflow

[aaronc]

Also happy to pick this up @flagrede if you're busy with other stuff. Seems like it should be relatively straightforward

[flagrede]

@aaronc That's great, I'll try to move forward with this PR today or tomorrow at worst.

[flagrede]

@aaronc I was able to make some progress today, I fixed 2 issues 05fe442 and 046236a
But it seems a bit less straightforward than expected, I'm having issues with lerna commands which don't support the workspace:* prefix now.

[flagrede]

Bun is now set up for all packages. The only limitation is that I could not get absolute import to work with web-components (mainly because of storybook) but this could be a follow-up issue.
Also, all Lerna scripts have been replaced by bun commands, we just have to keep Lerna for the version command used to make new releases.

[aaronc]

Why don't we need this?

[flagrede]

I could not get tsconfigPaths to work with the bun migration (it was needed for absolute path to work in storybook). I think it's more related to our configuration rather than a bun-specific issue but as I was saying here this is not blocking and we can investigate it further in a follow-up issue.

Will try to replace the command before merging to see if it works well.
