This is a requested kata, where I had to write a simple application to perform simple customer/accounts management.

The application is written in Java 21, using Spring Boot.

I also wrote a simple frontend application using Angular. This application is available in the client folder.

To run the spring application locally, you need to have Java 21 installed on your machine.

./gradlew bootRun

The application will be available at http://localhost:8080

To run the frontend application locally

cd client && npm run start

The application will be available at http://127.0.0.1:4200

To run the application using docker, you need to have docker/podman installed on your machine.

The docker image is already built and available on github packages https://github.com/jacquant/capgemini-kata/pkgs/container/capgemini-kata%2Fcapgemini To pull the image:

docker pull ghcr.io/jacquant/capgemini-kata/capgemini:latest

and run it:

docker run -p 8080:8080 ghcr.io/jacquant/capgemini-kata/capgemini:latest

The application will be available at http://localhost:8080. By accessing this endpoint, you will reach the web application.

The application exposes a swagger UI, which can be accessed at http://localhost:8080/swagger-ui/index.html

The application provides 4 endpoints:

• GET /api/v1/customers: returns the list of all customers: extra endpoint build to test the UI application
• GET /api/v1/customers/{id}: returns the customer with the given id
• POST /api/v1/customers: creates a new customer: extra endpoint build to test the UI application
• POST /api/v1/customers/{id}/accounts: creates a new account (with initial amount) for the customer with the given id

The Angular application provides a simple UI to test the application. The application usage is pretty straightforward:

• Create customers through the Create a new customer button. Will display a popup to enter the customer information
• Select the current customer from the table. Once selected, the row will be highlighted in purple.
• Create an account for the selected customer through the Create a new account button. Will display a popup to enter the account information
• Select the current account from the table. Once selected, the row will be highlighted in blue.
• Read the table of transactions for the selected account.
