Example TypeScript Lambda

This is an example of a TypeScript lambda, using:

• NPM workspaces
• GitHub Actions for CI (view it here)
• Riff-Raff for CD (view it here)
• @guardian/tsconfig for TypeScript configuration
• @guardian/cdk for infrastructure
• @guardian/eslint-config-typescript for ESLint configuration
• @guardian/prettier for Prettier configuration

Logs appear in Central ELK.

It's quite opinionated, using:

• esbuild to compile TypeScript to run on AWS Lambda
• Jest for testing

The aim is for this to be a starting point for a new application. Note, however, that there is a risk the repository might need updating. For example, dependency versions, or Node version.

Usage

1. Fork (or clone¹) this repository
2. Add your code to packages/lambda/src
3. Deploy via Riff-Raff

You'll want to edit some parts of the infrastructure in packages/cdk to ensure the app is deployed to the desired AWS account.

Footnotes

1. If cloning, you'll also want to update the remote url to match your repository ↩
