Datadog Lambda Library for Node.js (12.x, 14.x, 16.x, and 18.x) enables enhanced Lambda metrics, distributed tracing, and custom metric submission from AWS Lambda functions.
Follow the installation instructions, and view your function's enhanced metrics, traces and logs in Datadog.
Follow the configuration instructions to tag your telemetry, capture request/response payloads, filter or scrub sensitive information from logs or traces, and more.
For additional tracing configuration options, check out the official documentation for Datadog trace client.
Datadog's Continuous Profiler is now available in beta for NodeJS in version 6.87.0 and layer version 87 and above. This optional feature is enabled by setting the DD_PROFILING_ENABLED environment variable to true. During the beta period, profiling is available at no additional cost.
The 5.x.x release introduces version 2 of the Datadog tracer, dd-trace-js. This includes a few breaking changes, and the migration guide found here.
The first 5.x.x version was released with Lambda Layer version 69.
The 6.x.x release introduces support for the node 16 runtime and esm modules.
If you are using node 12 and installing the NPM module instead of the layer, redirecting your handler to the path node_modules/datadog-lambda-js/dist/handler.handler will no longer work. The path should be updated to node_modules/datadog-lambda-js/dist/handler.handler.cjs. This won't affect users of node 14, 16, or users of node 12 with the lambda layer.
