Feb 1, 2025February 2025 monthly summary for repository systeminit/si. Key deliverables included: (1) Frontend Data Flow Rearchitecture with Materialized Views (Atoms) in Frigg, introducing a KV-stored atom layer, a dependency graph for the views, and a WebSocket channel to broadcast atom changes for efficient data synchronization. (2) Diagram Visualization: Unified Edge Visibility, aligning edge rendering with component/prop selection for a consistent, context-aware diagram experience. (3) Enhanced Error Handling and Source Map Tooling, enabling source maps, decoding stack traces, and improving source map generation for actionable debugging in development and production. Impact and business value: Faster, more reliable data flow; clearer, more consistent diagrams that reduce context-switching; and improved debugging capabilities, accelerating MTTR. No major customer-reported bugs were rolled back this month; instead, reliability and observability were improved through the tooling work. Technologies/skills demonstrated: frontend architecture redesign, KV-store-backed atom storage (Frigg), dependency graph instrumentation, real-time event broadcasting via WebSockets, graph visualization consistency, and advanced error reporting with source maps across a Vue/JS frontend stack.
