Beacon Node.js 1.0.0

Beacon Node.js 1.0.0

This release publishes the first public Beacon Node.js npm package: @beacon-observability/profiler-nodejs@1.0.0.

Highlights

• Publishes the experimental Beacon-owned Node.js profiling bridge with wall and heap profiling through @datadog/pprof.
• Maps OpenTelemetry resource attributes to profiling tags.
• Produces receiver-compatible pprof attachments and can export multipart profile batches to a configured profiling endpoint.
• Keeps all inherited OpenTelemetry packages outside the Beacon publication scope.

Validation

• Beacon Node.js CI passed on Node.js 18.19, 20, 22, and 24.
• Project metadata and pinned upstream provenance passed validation.
• The profiler compiled successfully and all 6 unit tests passed.
• The exact npm tarball was inspected, installed in a clean application outside the repository, and its public API was verified.
• The package was downloaded again from the public npm registry and matched the validated candidate exactly.

Known limitations

• The profiler exports the documented compatible multipart pprof layout; it is not an implementation of the OpenTelemetry Profiles signal.
• Receiver compatibility depends on the configured profiling endpoint.
• The complete inherited upstream test matrix and receiver compatibility matrix are outside this release scope.
