Installation

You have 2 ways of consuming those utilities:

• NPM modules
• Lambda Layer

Lambda layers

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

NPM modules

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
