Experimental

@aws-cdk/aws-applicationsignals-alpha is an experimental (alpha) package: its API may change in any release, without a major version bump.

NodeInjector Class ​

Node.js-specific implementation of the SDK injector. Handles Node.js auto-instrumentation setup and NODE_OPTIONS configuration.
