Build: Consolidate and update nx versions

[mrginglymus]

What I did

Way back when nx was updated. However, this PR missed @nx/vite et al, effectively duplicating the number of nx dependencies.

I noticed this while poking through the lockfile looking for easy trims, and figured I'd throw a PR together to see what explodes.

Checklist for Contributors

Testing

The changes in this PR are covered in the following automated tests:

• stories
• unit tests
• integration tests
• end-to-end tests

Manual testing

This represents only a patch release in the main version of nx, so I expect testing here to be a case of everything will work fine as it did before, or catastrophic failure. If things were somehow working with mismatched versions but fail with matched versions, something has gone terribly wrong.

Greptile Summary

Updated On: 2025-09-14 19:59:59 UTC

This PR consolidates and updates nx dependency versions across the Storybook monorepo by aligning all nx-related packages to version 20.8.2. The changes update @nx/vite and @nx/workspace from version 20.2.2 to 20.8.2, and nx from ^20.4.0 to 20.8.2 in the root package.json.

The motivation for this change stems from a previous PR (#30460) that updated the main nx package but missed updating related nx packages like @nx/vite, creating version mismatches that resulted in duplicate dependencies in the lockfile. This type of version fragmentation is common in monorepos when dependencies are updated incrementally rather than as a cohesive group.

The change follows best practices for monorepo tooling where related packages from the same ecosystem should be kept in sync. Nx is Storybook's build and development tooling infrastructure, used for managing the complex monorepo structure, running tasks, and coordinating builds across multiple packages. By consolidating these versions, the PR reduces the dependency footprint and eliminates potential compatibility issues between different versions of the same toolchain.

This represents a patch-level upgrade (20.2.2 → 20.8.2) that includes bug fixes and improvements without breaking changes, making it a safe consolidation that should maintain full backward compatibility.

Confidence score: 5/5

• This PR is safe to merge with minimal risk as it only consolidates versions of related tooling dependencies
• Score reflects the patch-level nature of the upgrade and the fact that mismatched versions were already working, so aligned versions should work even better
• No files require special attention as this is a straightforward dependency version alignment
