…8574) ## Summary Fixes reroute node styling in Vue Nodes 2.0 by hiding slot labels when slot names are intentionally empty. | Before | After | | --------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------- | | <img width="1437" height="473" alt="image" src="https://github.com/user-attachments/assets/603f52e0-7b75-4822-8c91-0a8374cc0cb6" /> | <img width="1350" height="493" alt="image" src="https://github.com/user-attachments/assets/38168955-4d35-4c61-a685-a54efb44cd5d" /> | ## Problem Reroute nodes displayed unwanted fallback labels ("Input 0", "Output 0") instead of appearing as minimal connection-only nodes. This happened because: - Reroute nodes intentionally use empty string (`""`) for slot names - Slot components used `||` operator for fallback labels, treating `''` as falsy ## Solution - Add `hasNoLabel` computed property to detect when all label sources (`label`, `localized_name`, `name`) are empty/falsy - Derive `dotOnly` from either the existing prop OR `hasNoLabel` being true - When `dotOnly` is true: label text is hidden, padding removed (`lg-slot--dot-only` class), only connection dot visible Combined with existing `NO_TITLE` support from #7589, reroutes now display as minimal nodes with just connection dots—matching classic reroute appearance. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit ## Release Notes * **Bug Fixes** * Enhanced input and output slot label handling to automatically conceal labels when unavailable * Improved fallback display names for slots with more reliable naming logic <!-- end of auto-generated comment: release notes by coderabbit.ai --> ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-8574-fix-vue-nodes-hide-slot-labels-for-reroute-nodes-with-empty-names-2fc6d73d365081c38031e260402283d3) by [Unito](https://www.unito.io)
