The tracer package for the AWS Lambda Powertools for TypeScript library

Package Exports

  • @aws-lambda-powertools/tracer
  • @aws-lambda-powertools/tracer/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@aws-lambda-powertools/tracer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Features

  • Tracer - Utilities to trace Lambda function handlers, and both synchronous and asynchronous functions
  • Logger - Structured logging made easier, and a middleware to enrich log items with key details of the Lambda context
  • Metrics - Custom Metrics created asynchronously via CloudWatch Embedded Metric Format (EMF)
  • Parameters (beta) - High-level functions to retrieve one or more parameters from AWS SSM, Secrets Manager, AppConfig, and DynamoDB

Getting started

Installation

The AWS Lambda Powertools for TypeScript utilities follow a modular approach, similar to the official AWS SDK v3 for JavaScript.
Each TypeScript utility is installed as standalone NPM package.

Install all three core utilities at once with this single command:

npm install @aws-lambda-powertools/logger @aws-lambda-powertools/tracer @aws-lambda-powertools/metrics

Or refer to the installation guide of each utility:

👉 Installation guide for the Tracer utility

👉 Installation guide for the Logger utility

👉 Installation guide for the Metrics utility

👉 Installation guide for the Parameters utility

Examples

Serverless TypeScript Demo application
