Playground-backend-service

Playgrounds Create a playground API (REST (Spring Boot) or library (jar) – which one is your decision) that implements business logic for playground management These are things that we expect library will do:

define clear and usable domain classes, beans, components (interfaces) that should be used access required functionality/data
API creates and manages play sites that consists of double swings, carousel, slide and a ball pit. API allows to create combinations of play sites (for example two swings, one slide etc.)
API should not use DB or persistent data store, In-memory storage is enough.
API should be able to add kids to play sites (we know kid's name, age, ticket number)
API should not allow to add more kids to them than specified in configuration of play site (done once on initialization)
it should be possible to enqueue kid or receive negative result if kid does not accept waiting in queue. API register queues on play sites when tries to add kid to play site, that is full, and kid accepts waiting in queue).
it should also be possible to remove kid from play site / queue
API should provide play site utilization. Play site utilization is calculated differently for each play site (most of play sites utilization is percent of capacity taken (3/10 places taken for 30% utilization), double swings 100% if full capacity, 0 if 1 or 0 kids, some not yet known play sites can have different calculation implementations, this possible extension requirement should reflect in design). Utilization is measured in %
API should be able to provide a total visitor count during a current day on all play sites

Minimal Spring Boot sample app.

Requirements

For building and running the application you need:

Running the application locally

There are several ways to run a Spring Boot application on your local machine. One way is to execute the main method in the *.Application class from your IDE.

Alternatively you can use the Spring Boot Maven plugin like so:

mvn clean
mvn compile package -DskipTests=true
mvn spring-boot:run

Run the application using docker-compose

docker-compose -f docker-compose.yaml build
docker-compose -f docker-compose.yaml up
docker-compose -f docker-compose.yaml down

Run the application backend-service/frontend-service

Backend-service (http://localhost:8080/swagger-ui/index.html#)

mvn clean
mvn compile package -DskipTests=true
mvn spring-boot:run

Frontend-service (http://localhost:9090)

yarn
yarn build
yarn start
