Greptile Overview

Summary

This PR adds warning messages when users attempt to delete default destination nodes in realtime pipelines. The implementation spans four files:

• Enhanced ConfirmDialog component to support warning messages with theme-appropriate styling using Tailwind classes
• Added detection logic in useDnD.ts to identify default destination nodes by comparing stream names between input and output nodes
• Integrated warning display in both Stream.vue and CustomNode.vue components to show the warning when deleting default destination nodes

Key changes:

• Warning appears only for realtime pipelines where a default destination node was automatically added
• Uses conditional logic to show appropriate warning message explaining data flow impact
• Maintains consistent UI styling across light and dark themes

Confidence Score: 4/5

• This PR is generally safe to merge with minor improvements needed
• The implementation is solid but has one potential runtime error and minor style issues that should be addressed
• Focus on web/src/plugins/pipelines/useDnD.ts for the null check fix

Greptile Overview

Summary

This PR adds warning messages when users attempt to delete default destination nodes in realtime pipelines. The implementation correctly identifies default destination nodes by comparing the destination stream name with the input stream name and displays contextual warnings through an enhanced confirm dialog.

Key Changes:

• Enhanced ConfirmDialog: Added optional warningMessage prop with themed warning banner and responsive width
• Default Detection Logic: New checkIfDefaultDestinationNode() helper in useDnD.ts to identify auto-created destination nodes
• Warning Integration: Both Stream.vue and CustomNode.vue now show warnings when deleting default destinations
• Constants Extraction: Warning message moved to dedicated constants file for reusability

Issues Found:

• Minor potential null access issue in getInputNodeStream() function that should be addressed

The implementation follows good separation of concerns with the detection logic centralized in useDnD.ts and shared constants. The UI properly handles both light and dark themes for the warning display.

Confidence Score: 4/5

• This PR is safe to merge with minimal risk after addressing the null access issue
• Score reflects well-structured implementation with good separation of concerns, proper theme handling, and effective warning system. One minor logical issue with potential null access reduces confidence slightly but doesn't impact core functionality.
• Pay close attention to web/src/plugins/pipelines/useDnD.ts for the potential null access issue
