lambda-utils

@axis-tech-co/axis-lambda-utils is the runtime companion to the constructs: helpers your handler code imports at execution time, not synth time. Where constructs shape infrastructure, lambda-utils shapes what runs inside a function.

The helpers

• Masked Logger — structured logging that scrubs secret-shaped values.
• Tracer — X-Ray tracing over AWS Lambda Powertools.
• Middy Middleware — the error-handler and logging middleware.
• Dynamo & SSM Helpers — thin, typed runtime access.
• Alerting Adapter — the Slack/Teams dispatcher the observability stack deploys.

Typed errors

The package also exports typed error classes — AtfError and its subclasses (NotFoundError, ValidationError, ForbiddenError, ConflictError, QuotaExceededError) — plus serializeError and statusCodeFor. Throw a typed error from service code and the error-handler middleware maps it to the right HTTP status. The full class list is in the generated API reference.
