15-254: Good implementation: Comprehensive Redis mock.The
RedisMockclass provides a thorough implementation of all Redis methods needed by the service, with detailed logging for debugging. The implementation is well-structured and follows good object-oriented design principles.However, there's a small optimization opportunity in the
getStorageStatemethod:acc[key] = - typeof inMemoryStorage[key] === "string" - ? inMemoryStorage[key] - : inMemoryStorage[key]; + inMemoryStorage[key];The conditional expression always returns the same value regardless of the type, so it can be simplified.
187-196: Beware of potential memory leaks in expire implementation.The
expiremethod usessetTimeoutto automatically delete keys after a specified time. While this works for a mock implementation, be aware that in a long-running process with many keys, this could potentially lead to many timers being created.Consider adding a method to clear all timeouts when needed, especially for testing scenarios where you might want to reset the state.
8-9: Consider adding a reset method for testing.Since
inMemoryStorageis a singleton shared across all instances ofRedisMock, it would be helpful to add a staticreset()method that clears all data. This would be useful for ensuring tests don't affect each other when they share the same mock./** * Reset all in-memory storage (for testing) */ static reset(): void { for (const key in inMemoryStorage) { delete inMemoryStorage[key]; } console.log('[MOCK REDIS] Storage reset'); }

2-2: Good refactoring: Redis client abstraction.This change improves the code by decoupling the rate limiting middleware from Redis client initialization logic. Importing a pre-initialized redis instance from storage.js follows the separation of concerns principle and makes the middleware more testable.
53-56: LGTM: Proper pipeline usage for batched operations.The Redis pipeline implementation is correctly used here to batch commands for better performance, reducing network roundtrips to Redis.

22-24: Good implementation: Improved Redis mock abstraction.Replacing the custom in-memory Redis mock with an external
RedisMockclass improves code organization and maintainability. This approach centralizes the mock implementation and makes it reusable across the codebase.packages/rss/service/src/redis-mock.ts (3)
1-9: Well-structured module with clear documentation.The module has excellent documentation explaining its purpose and implementation details, which makes it easier for other developers to understand and use.
229-232: Good pattern: Factory method for pipeline.The pipeline method correctly creates and returns a new instance of
RedisMockPipeline, following the same pattern as real Redis clients.
260-314: Good implementation: Redis pipeline mock.The
RedisMockPipelineclass correctly implements the chain-able API pattern used by Redis pipelines, storing commands for later execution. The implementation handles errors gracefully by catching them and continuing execution.Note that this behavior differs slightly from a real Redis pipeline where an error might cause the entire pipeline to fail. However, this approach is appropriate for a mock implementation in a testing environment.
