AWS X-Ray SDK for Koa

Official AWS X-Ray middleware for Koa 2.x that records incoming/outgoing requests and responses. Version 3.12.0 is latest stable; released with the aws-xray-sdk-node monorepo on a monthly cadence. Key differentiator: deep AWS service integration with automatic segment/subsegment management via cls-hooked. Supports ESM and CJS; ships TypeScript types. Requires aws-xray-sdk-core and Koa 2.x. Offers both automatic (default) and manual tracing modes. Minimal overhead but can cause context issues if middleware order is wrong.
