Walkthrough

This PR updates the @opensecret/react dependency from 1.5.1 to 1.5.2 and adds bulk delete functionality to LocalStateContext.tsx. The clearHistory function now attempts a single bulk delete operation via delAll before falling back to the existing per-key deletion approach if the bulk operation fails.

Changes

Cohort / File(s)	Summary
Dependency Update frontend/package.json	Updated @opensecret/react from 1.5.1 to 1.5.2 in dependencies
Bulk Delete Logic frontend/src/state/LocalStateContext.tsx	Added delAll to destructured OpenSecret hook API; modified clearHistory to attempt single bulk delete operation with automatic fallback to manual per-key deletion if bulk operation fails

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• LocalStateContext.tsx: Verify the bulk delete flow logic and error handling path to ensure fallback behavior works correctly when delAll fails
• Error handling semantics: Confirm that the fallback deletion strategy maintains the same end state as the bulk operation
• Dependency compatibility: Ensure the new delAll API from @opensecret/react 1.5.2 is properly integrated and tested

Poem

🐰 A dependency hops to brand new heights,
Bulk deletes now work with all their might,
When one path fails, we've got a plan,
Fallback logic, swift and grand—
History cleared in rabbit's time! ✨

Greptile Overview

Greptile Summary

Optimized the clearHistory function by replacing individual key deletion with a batch delAll() operation from @opensecret/react v1.5.2. The implementation includes proper error handling with a fallback to the previous manual deletion approach for backward compatibility if the batch operation fails.

• Updated @opensecret/react dependency from 1.5.1 to 1.5.2
• Refactored clearHistory() to use delAll() for more efficient bulk deletion
• Added try-catch with graceful fallback to manual deletion if batch delete fails
• Maintains backward compatibility with older SDK versions

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are straightforward and well-implemented: a simple dependency upgrade and an optimization that improves performance. The code includes proper error handling and a fallback mechanism, ensuring backward compatibility if the new batch delete operation fails. No breaking changes or logical errors detected.
• No files require special attention

frontend/src/state/LocalStateContext.tsx (1)

287-299: Excellent implementation of bulk delete with graceful fallback.

The try-catch pattern with fallback to manual deletion is well-designed:

• Prioritizes the optimized delAll() bulk operation
• Gracefully degrades to the previous implementation on any failure
• Handles backward compatibility, partial failures, and missing method scenarios
• Uses Promise.all for efficient parallel deletion in the fallback path
