Problem Statement

When using Uniform CLI commands to update component patterns, you may notice that Slot Section IDs are being regenerated instead of preserved. This can cause cascading changes in places where the pattern is used, as the system treats these as new components rather than updates to existing ones.

Solution

This issue occurs because the component pattern YAML file is missing the _id property for slot sections, which causes Uniform to generate a new ID every time you push the pattern.

To resolve this issue, you need to include component IDs when pulling pattern data from Uniform:

1. When using uniform sync pull, component IDs are automatically included

2. When using specific commands like uniform canvas component-pattern, you must explicitly add the --componentIDs flag:

uniform canvas component-pattern pull --componentIDs

This ensures that all slot sections and components retain their original IDs when you pull the pattern data, preventing ID regeneration during subsequent push operations.

The --componentIDs flag is essential for maintaining consistency between your local pattern files and the patterns stored in Uniform, avoiding unintended cascading changes across your project.
