I implemented the credit card validator case study application using the following:

• React + MUI for the frontend/ui
• tRPC for the API

It can be ran locally or deployed to AWS using CDK

yarn install
cd cdk
npm install

It can be ran locally by running the individual UI / API:

yarn ui:dev &
yarn api:dev

Place credentials in a creds.json file under cdk/scripts that looks like:

{
  "accessKeyId": "",
  "secretAccessKey": "",
  "region": "us-west-2"
}

Update the account id in cdk/bin/cdk.ts to the AWS account id you are deploying to.

First build the UI/API

yarn api:build
yarn ui:build

Then run the CDK deployment

cd cdk
npm run cdk "deploy --require-approval never"
