Turbo Repo in CI

[trm217]

Hi everyone

I have recently been thinking about automating more tasks in a turborepo that contains three Next.js apps.
Now I came to wonder, is there a way to get a list of all apps/packages inside a turborepo that have changed relative to another branch?

Imagine the following setup: We have a turborepo setup containing a package chart-ui and two apps chart-editor and docs, with chart-editor having chart-ui as a dependency.

Now let's say I update the source of package chart-ui and now want to run a bundle-analysis automation for all apps afflicted by changes.

So in this case we would only want chart-editor to run the bundle-analysis automation, since it's affected by the changes made to chart-ui but we wouldn't want to run the automation for the docs app.

How did you guys solve this in your mono-repos?

Edit:
I am aware that I can run scripts for changed apps/packges using --filter, however I can't seem to find a way to retrieve just a list of the apps

Need the exact same thing to customize CI rather than rely on turbo's built-in functionality.

--dry-run display details about the affected packages. Does this help?
