Beyond Electron: Building Self-Healing Desktop Apps with Process Monitoring

Production desktop applications frequently encounter catastrophic failures when background processes crash or enter deadlock states, leaving users with frozen, unresponsive interfaces. This article details a production-grade watchdog and auto-healing strategy that transforms a dual-process architecture into a self-recovering system, detecting and resurrecting failed backend processes automatically. By implementing lightweight health monitoring instead of relying on heavy electron frameworks, developers can build robust multi-process desktop applications that maintain reliability and responsiveness under real-world failure conditions.
