The Powertools for AWS Lambda (TypeScript) utilities is packaged as a single AWS Lambda Layer
👉 Installation guide for the Powertools for AWS Lambda (TypeScript) layer
The Powertools for AWS Lambda (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/metricsOr refer to the installation guide of each utility:
