This tutorial builds a soft real-time event monitoring system using Go for deadline-aware backend processing with goroutines and contexts, React with TypeScript for the frontend, and WebSockets for low-latency streaming. The system generates time-sensitive events, enforces deadlines, deliberately drops late work to maintain guarantees, and visualizes latency and missed deadlines. Key concepts include treating time as explicit data, applying backpressure through bounded channels, using requestAnimationFrame for UI updates, and understanding that dropping events under load preserves real-time guarantees better than unbounded buffering. ## Full article daily.dev links to this article rather than hosting it.
