generator-aws-lambda-typescript v1.0.1

Yeoman AWS Lambda TypeScript generator

It's a generator to create skeleton code for creating size-optimized, production grade AWS Lambda packages.

Benefits

• Reduces size of Lambda by using WebPack and tree shaking
• Lambda code in TypeScript
• Configured Jest for testing
• CI/CD package:prod NPM command to make full CI/CD build

Quick start

Install generator globally

npm i -g generator-aws-lambda-typescript

(For NIX environments prefix with sudo).

Create a new folder for project and cd into it. Call

yo aws-lambda-typescript

Customizations

When creating lambda it may be required to interact with other AWS services by using aws-sdk. Install required packages using npm i @aws-sdk/package-name.

When building, this packages will not be put in final JS file, as are all provided by runtime (further reduction of output size).

For testing most probably interesting will be Jest documentation how to mock system modules (AWS SDK), so code can be tested without calling real services.
