Technical Architecture: Web Worker Timers & Cognitive Focus Rhythms
Modern browsers aggressively throttle setTimeout() and setInterval() timers down to once per second (or even once per minute) in background tabs to conserve battery and CPU resources. This throttling causes standard browser timers to drift and lose accuracy when users switch tabs. Khalasna solves this client-side by delegating timer countdown ticks to a dedicated Web Worker running on an isolated background thread unaffected by main-thread throttling. The worker posts high-precision 1000ms tick messages back to the primary UI thread, updating the page document.title and audio sound synthesis using the Web Audio API (AudioContext) without requiring external audio file downloads. Session counts are persisted in the browser's localStorage, ensuring continuous, zero-drift productivity tracking with complete local privacy.
