Starter for AWS Lambda functions written in Typescript

Simple starter for new AWS Lambda functions. Provides base tools for testing (JEST), validating (TSLint) and custom scripts.

Project structure

• app/jest.config.js - JEST framework configuration,
• package.json - NPM configuration,
• tsconfig.json - Typescript configuration required to run ts-node,
• cdk.json - AWS CDK configuration,
• bin/* - build and deploy scripts - referenced in package.json
• app/tslint.json - Tslint rules,
• app/tsconfig.json - Typescript configuration required to build and run application,
• app/src - example AWS Lambda handler,
• app/test - unit tests executed by JEST,
• stack/* - Cloudformation stack configuration in CDK format

Commands

• npm test - run unit tests from test directory with framework JEST,
• npm run tslint - check source files with Tslint,
• npm run build - compiles files from src with Typescript compiler and outputs result to build directory,
• npm run package - builds deployment archive from compiled sources and dependencies localized in node_modules.
• npm run deploy - deploys lambda function with AWS CDK To save space npm prune --production should be run before this command. Output is saved in file function.zip.
