WorkoutTracer CDK TypeScript Project

This repository contains the AWS CDK infrastructure code for the WorkoutTracer application, written in TypeScript.

The cdk.json file tells the CDK Toolkit how to execute your app.

Project Structure

• bin/: Entry point for the CDK app (workout_tracer_cdk.ts)
• lib/: CDK stack definitions (API, Auth, Website, Database, DNS, Pipeline)

Environments

This project supports multiple deployment stages (e.g., Staging, Prod). Environment configuration is managed in cdk.env.json.

Stacks

• DatabaseStack: DynamoDB and related resources
• AuthStack: Cognito User Pool, Identity Pool, and triggers
• WebsiteStack: S3 static site, CloudFront, Route53, and deployment
• ApiStack: Lambda, API Gateway, and logging
• ApiDnsStack: Custom domain and DNS for API Gateway

Useful commands

• npm run build compile typescript to js
• npm run watch watch for changes and compile
• npm run test perform the jest unit tests
• npx cdk deploy deploy all stacks to your default AWS account/region
• npx cdk diff compare deployed stack with current state
• npx cdk synth emits the synthesized CloudFormation template

Deploying a Specific Stage

To deploy only a specific stage (e.g., Staging):

npx cdk deploy WorkoutTracer-DatabaseStack-Staging WorkoutTracer-AuthStack-Staging WorkoutTracer-WebsiteStack-Staging WorkoutTracer-ApiStack-Staging WorkoutTracer-ApiDnsStack-Staging

Environment Configuration

Edit cdk.env.json to update domain names, certificate ARNs, callback URLs, and other environment-specific settings.

Notes

• All resource names are suffixed with the deployment stage (e.g., WorkoutTracer-ApiStack-Staging).
• S3 bucket names and other resources requiring lowercase use .toLowerCase() on the stage name.
• The pipeline can be extended to support CI/CD with GitHub and CodePipeline.

Formatting

npx prettier --write "**/*.ts"
