Express, as a lightweight Node.js web framework, enhances real-time application performance when integrated with edge computing. Its middleware mechanism, optimized for low latency and resource efficiency, reduces edge environment latency by 23%. Geo-aware routing enables dynamic distribution, lowering latency for Singapore users from 210ms to 89ms. A fine-grained caching strategy achieves a 78% hit rate for product APIs, reducing origin server load by 63%. Edge error handling supports automatic failover, while an edge session solution reduces shopping cart operation P99 latency from 320ms to 112ms. By running Express routes via an adaptation layer on edge functions, median API latency drops from 140ms to 47ms. Extending the monitoring system to edge dimensions optimizes inter-node routing, and adjusted security middleware cuts inspection latency from 85ms to 12ms while maintaining compliance.
