RxJS in Action: Creating a Robust Console Log Upload Service with Priority Handling
The article details building a robust log upload service with RxJS, emphasizing priority-based queuing. It captures console logs (log, error, warn), batches them for efficient uploads, and prioritizes errors over warnings. Key features include single active uploads, immediate error handling, delayed warning uploads, and queue management to prevent data loss during network issues. The implementation intercepts console methods, uses local storage for log management, and leverages RxJS operators like switchMap and debounceTime. Advanced logic ensures error priority, buffered warnings, and smooth state transitions, offering developers an efficient and reliable logging solution.
