Hello, I have this repo with multiple sst/cdk stacks (one per region)). I was trying to move the common dependencies (basically all) to the root folder but I didn't manage to do that. Has anyone else tried to do something similar?

Hey Paulo, what's the issue you are running into? Are you getting an error?

Hey @Jay. I got some. I first tried to simply delete all deps from my sub folder

root
|-- region-a
|   |-- sst.json
|   |-- package.json (no deps)
|
|-- region-b
|   |-- sst.json
|   |-- package.json (no deps)
|
|-- package.json (all deps)

running

npx sst deploy

from the region folder, I got this

npx: installed 1 in 1.474s
command not found: sst

I moved the

@serverless-stack/cli

to the region folder and got this

There was a problem transpiling the source.

then, I moved

@serverless-stack/resources

to the region folder and got this:

Deploying stacks

The deployment seems to work, but with these warnings, so I didn't try anything else

Ah got it. Just tried this. Yeah these warnings are because esbuild is traversing all your dependencies and those have some issues. SST fixes this by looking at all the dependencies in your

package.json

and ignoring them automatically. But since the

package.json

in your sub-dir doesn't have all those dependencies (

aws-cdk

), it's not able to ignore them. A couple of solutions. You can just ignore these warnings for now. Or disable esbuild bundling (https://docs.serverless-stack.com/constructs/Function#bundle) if you get errors instead or warnings. Or for this setup, use Yarn Workspaces. That way, you can still list all the dependencies in the sub-dir correctly, and Yarn will lift all the dependencies to the root and manage it for you.
