• 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)

Find the complete project's documentation here.

You have 2 ways of consuming those utilities:

• NPM modules
• Lambda Layer

The AWS Lambda Powertools for TypeScript utilities is packaged as a single AWS Lambda Layer

👉 Installation guide for the AWS Lambda Powertools for TypeScript layer

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
