@sekimori/codemod

sekimori migrate — a ts-morph codemod that moves aws-xray-sdk-core and Powertools for AWS Lambda (TypeScript) Tracer usage to the OpenTelemetry API, and emits a migration report listing constructs that have no mechanical mapping.

What it rewrites

• import { Tracer } from "@aws-lambda-powertools/tracer" → createTracer from sekimori/tracer; new Tracer({ serviceName }) → createTracer(serviceName)
• AWSXRay.captureAWS* / captureHTTPs* → the wrapped value (contrib instrumentation takes over)
• AWSXRay.getSegment() / resolveSegment() → trace.getActiveSpan()
• AWSXRay.captureAsyncFunc(name, fn) / captureFunc → tracer.startActiveSpan(name, fn), rewriting subsegment.close() → end, addAnnotation → setAttribute, addError → recordException, addMetadata → metadata.* attributes

Everything else — setSegment, addNewSubsegment, decorators, CJS require, aliased imports — is listed in the report as manual findings, not silently broken.

Usage

sekimori migrate src/           # dry-run report
sekimori migrate src/ --write   # rewrite in place
sekimori migrate src/ --json    # machine-readable report

Programmatic: transformSource(source) / migrateFile(path, { write }) / migratePaths(paths, { write }).
