What is the correct way to upgrade pdk monorepo dependencies?

[janeklb]

I have a pdk (typescript) monorepo project with a handful sub-projects (in the packages/ directory). I'm using pnpm.

What's the right way to upgrade all the dependencies in the monorepo? Afaict there are a few options:

• pdk run upgrade-deps (will run the upgrade-deps projen task, via aws-pdk's monorepo project)
• pdk run upgrade (will run the upgrade projen task)
• pnpm update --recursive (will run the pnpm-native update process)

It seems like upgrade-deps is the right way to do it, but it's a little confusing to see an upgrade projen task also available. Interestingly upgrade-deps does not upgrade pdk itself..

Furthermore, confusion is exacerbated by the fact that if you run pdk upgrade (or update or up), as opposed to pdk run upgrade, you'll end up triggering pnpm's upgrade.
I think there was a recent change that allowed you to cdk deploy via pdk deploy (instead of pdk run deploy) when using pnpm since pnpm has it's own deploy command.. but this is probably out of scope for pdk since the upgrade task comes from projen.

Hi - upgrade-deps is the way to go from a monorepo perspctive as it will update all packages within the monorepo.

upgrade on the other hand will only update packages for the current package it is executed from. Probably a poor choice of naming from my perspective so I apologize for that. We should probably also add supporting documentation as this is lacking at the moment.

In relation to pdk itself not upgrading, do you mean your dependencies on @aws/pdk?

The pnpm upgrade issue is definitely a bug that needs to be addressed. Let me go ahead and create an issue to track these here: #653

I will close this discussion and ask that you please respond to my questions in the linked issue :)
