Logic

  1. 2 instances of Player applications need to be run
  2. Player 1 will latch on port 8080 while player 2 will start on port 8090
  3. all changes to the score are stored as events in the event store

Frameworks used

  1. Axon
  2. Spring

Starting the application

With Auto Mode

start one instance with auto argument as shown below followed by another instance of application

Player 1 on auto mode

java -jar player-0.0.1-SNAPSHOT.jar auto

Player 2

java -jar player-0.0.1-SNAPSHOT.jar

Winner will be reported on the console

21-01-2019 15:40:20.687 [pool-1-thread-2] [player1] INFO  com.game.player.controller.GameController.onSuccess - GAME OVER !!

With Manual Mode

start both the instances and then fire

POST http://localhost:8080/game/start
{
	"initialValue":100
}

Player 1

java -jar player-0.0.1-SNAPSHOT.jar

Player 2

java -jar player-0.0.1-SNAPSHOT.jar

Winner will be reported on the console

21-01-2019 15:40:20.687 [pool-1-thread-2] [player1] INFO  com.game.player.controller.GameController.onSuccess - GAME OVER !!

API

to make a move in the game

curl -X PUT --data 100 -H "Content-Type: application/json" localhost:8090/game/{scoreId}/move

events as list of all individual moves made against a particular aggregate

curl -X GET localhost:8090/game/{scoreId}/events/

Open Concerns

  1. minor gap between the application start and port capture can lead to one instance not starting.
  2. events API shows all changes made against the aggregate inside its instance. Consolidated events from both the instances when sorted by Time can give exact details of all delta against the aggregate.
  3. Code coverage is not 100%
