101-110: Potential issue with repeatedEXPIREevents due tosetInterval.By replacing
setTimeoutwithsetInterval, theEXPIREevent will now be emitted repeatedly everyttlmilliseconds instead of just once after the TTL expires. This may lead to the cache entry being expired multiple times and could cause unintended side effects or performance issues.Consider whether the repeated emission of the
EXPIREevent is intentional. If the goal is to refetch and update the cache at regular intervals, ensure that the cache value is being updated appropriately. If only a single expiration is desired, you may want to retainsetTimeoutor adjust the logic to clear the interval after the first execution.

99-101: Improved test coverage for autoRefetch functionalityThe changes in this test case enhance the verification of the
autoRefetchfeature:
- The addition of
jest.advanceTimersByTime(100)simulates the passage of time equal to the TTL (100ms) set in theRunCache.set()call.- Updating the expectation to
toHaveBeenCalledTimes(2)correctly verifies that thesourceFnis called twice: once during the initial set operation and once after the TTL expires, triggering the auto-refresh.These modifications ensure that the test accurately checks the
autoRefetchbehavior, confirming that the cache automatically refreshes after the TTL expires.src/run-cache.ts (7)
90-93: Properly clearing existing intervals for cache keys.Good job ensuring that any existing intervals are cleared when setting a new cache entry for a key. This prevents multiple intervals from running simultaneously for the same key, which could cause unexpected behavior.
129-133: Ensureintervalis correctly stored in the cache entry.Storing the
intervalin the cache entry allows you to manage it later, such as clearing it when the cache entry is deleted. This is a good practice.
259-260: Clearing intervals when deleting cache entries.Great job clearing the interval associated with a cache entry when it is deleted. This helps prevent memory leaks and ensures that no unnecessary timers are left running.
275-277: Proper cleanup of intervals during cache flush.By iterating over all cache entries and clearing any active intervals, you ensure that flushing the cache fully cleans up all resources. This is important for maintaining optimal performance and resource management.
381-385: Addition ofonRefetchFailuremethod for global refetch failure handling.The new
onRefetchFailuremethod allows users to register a callback for handling refetch failures across all keys. This enhances the robustness of the cache by providing an explicit way to handle errors during auto-refetch operations.
390-397: Addition ofonKeyRefetchFailuremethod for key-specific refetch failure handling.Introducing
onKeyRefetchFailureenables users to register callbacks for refetch failures on specific keys. This provides fine-grained control over error handling for critical cache entries.
11-11: Ensure all references totimeoutare updated tointerval.You have updated the
CacheStatetype to include theintervalproperty. Please verify that all references totimeouthave been replaced withintervalthroughout the codebase to prevent any undefined behavior.Run the following script to check for any remaining references to
timeout:

3-3: Version update looks good.The package version has been correctly bumped from 1.4.0 to 1.4.1, which is appropriate for a minor patch update. This change is consistent with semantic versioning practices for backwards-compatible bug fixes.
README.md (3)
83-83: LGTM: Clear and consistent message.The updated console.log message for the specific key expiry event is clear and consistent with the style of other messages in the file.
106-110: 🧹 Nitpick (assertive)Approved with minor grammatical suggestion. Remember to add JSDoc comments in
run-cache.ts.The addition of the
onKeyRefetchFailureevent handler is valuable for specific error handling. However, there's a minor grammatical error in the console.log message. Consider updating it as follows:RunCache.onKeyRefetchFailure('Key', (cache: EventParam) => { - console.log(`Specific key has been failed to refetch`); + console.log(`Specific key has failed to refetch`); })Also, as per the PR objectives, please ensure that JSDoc comments for this function are added in the
run-cache.tsfile, not in this README.#!/bin/bash # Verify if JSDoc comments have been added for onKeyRefetchFailure in run-cache.ts ast-grep --lang typescript --pattern $'/** * $$$ */ export function onKeyRefetchFailure($$$) { $$$ }' run-cache.ts
101-105: Approved. Remember to add JSDoc comments inrun-cache.ts.The addition of the

99-107: LGTM: Improved test coverage for autoRefetch functionality.The changes to this test case enhance the verification of the
autoRefetchfeature:
- By advancing the timer twice and allowing for Promise resolution, the test now ensures that the cache is refreshed multiple times as expected.
- The updated assertion correctly reflects that the
sourceFnshould be called three times: once during initial set, and twice more after each timer advancement.These modifications provide a more thorough test of the cache's behavior over time, which is crucial for verifying the
autoRefetchfunctionality.

1-524: Commendable comprehensive test suite.The test file demonstrates a thorough approach to testing the RunCache functionality. It covers various scenarios including:
- Setting and getting cache values
- Handling of TTL (Time To Live)
- Auto-refetch behavior
- Error handling
- Event listeners for different cache operations
This comprehensive coverage helps ensure the reliability and correctness of the RunCache implementation.
Line range hint
420-458: Consider updating tests foronRefetchFailureandonKeyRefetchFailure.Given the changes to the
autoRefetchbehavior, it might be beneficial to review and potentially update the tests foronRefetchFailureandonKeyRefetchFailure. These tests should verify that the failure handlers are called appropriately with the newsetIntervalimplementation (assuming this change has been made in the main implementation).To help with this, could you run the following command to check the implementation of
onRefetchFailureandonKeyRefetchFailure?#!/bin/bash # Search for onRefetchFailure and onKeyRefetchFailure implementations echo "Searching for onRefetchFailure implementation:" rg 'onRefetchFailure' --type ts -A 10 echo "\nSearching for onKeyRefetchFailure implementation:" rg 'onKeyRefetchFailure' --type ts -A 10
Line range hint
1-524: Verify JSDoc additions foronRefetchFailureandonKeyRefetchFailure.The PR objectives mention adding JSDoc comments for the
onRefetchFailureandonKeyRefetchFailurefunctions. However, this test file doesn't contain the actual implementation of these functions. Please ensure that these JSDoc comments have been added to the main implementation file (likelyrun-cache.ts).To help verify this, could you run the following command to check for JSDoc comments for these functions?
#!/bin/bash # Search for JSDoc comments for onRefetchFailure and onKeyRefetchFailure echo "Searching for onRefetchFailure JSDoc:" rg '\/\*\*[\s\S]*?onRefetchFailure' --type ts -A 15 echo "\nSearching for onKeyRefetchFailure JSDoc:" rg '\/\*\*[\s\S]*?onKeyRefetchFailure' --type ts -A 15Also, please confirm if examples for these functions have been added to the
README.mdfile as mentioned in the linked issue #17.
99-107: 🧹 Nitpick (assertive)Please clarify the relationship between these changes and the PR objectives.
The PR title mentions updating
setTimeouttosetInterval, but this change is not directly visible in the modified test case. Could you please explain how these test modifications relate to thesetTimeouttosetIntervalupdate mentioned in the PR title? This will help ensure that the changes align with the stated objectives of the pull request.To help clarify this, could you run the following command to search for
setTimeoutandsetIntervalusage in the codebase?✅ Verification successful
Test modifications are aligned with the PR's objective to use
setIntervalinstead ofsetTimeout.
- The codebase uses
setIntervalinsrc/run-cache.ts, as confirmed by the search results.- The test file no longer references
setTimeout, ensuring consistency with the updated implementation.🏁 Scripts executed
