Welcome to your Eventual Project

Project Structure

The following folder structure will be generated.

├──infra # an AWS CDK application that deploys the repo's infrastructure
├──packages
    ├──service # the NPM package containing the my-service business logic

infra

This is where you control what infrastructure is deployed with your Service, for example adding DynamoDB Tables, SQS Queues, or other stateful Resources.

packages/service

This is where you add business logic such as APIs, Event handlers, Workflows and Activities.

Deployed Infrastructure

After deploying to AWS, you'll have a single stack named ai-bank containing your Service. Take a look at the structure using the Resources view in CloudFormation. Here, you can find a list of all the Lambda Functions and other Resources that come with a Service.

See the Service documentation for more information.

Scripts

The root package.json contains some scripts for your convenience.

Build

The build script compiles all TypeScript (.ts) files in each package's src/ directory and emits the compiled output in the corresponding lib/ folder.

pnpm build

Test

The test script runs jest in all sub-packages. Check out the packages/service package for example tests.

pnpm test

Watch

The watch script run the typescript compiler in the background and re-compiles .ts files whenever they are changed.

pnpm watch

Synth

The synth script synthesizes the CDK application in the infra/ package.

pnpm synth

Deploy

The deploy script synthesizes and deploys the CDK application in the infra/ package to AWS.

pnpm run deploy

Hotswap

The hotswap script synthesizes and deploys the CDK application in the infra/ package to AWS using cdk deploy --hotswap which can bypass a slow CloudFormation deployment in cases where only the business logic in a Lambda Function has changed.

pnpm run deploy
