noughts-and-crosses (minmax)

Explanation

A RESTful service to generate the next move in a noughts and crosses game.

Submit a board and the service will:

1. Check the move being requested is legal - e.g. placing an X on a board with 3 X's and 2 O's is illegal.
2. Look up the board in DynamoDb.
3. If board does not exist create and store it
4. Return the board.

Guide

Before starting the application make sure that Dynamodb is configured correctly and running (change Dynamodb config in database.clj).

To start the app run:

lein ring server-headless

The service exposes two endpoints http://localhost:3000/X/ and http://localhost:3000/O/. Send a board to the appropriate end point to get the next move.

Example

Request (OSX terminal): curl -X POST -H "Content-Type: application/json" -d '{"board": [["-", "-", "-"],["-", "O", "-"],["-", "X", "X"]]}' http://localhost:3000/O/

Response: {:next-move [["-" "-" "-"] ["-" "O" "-"] ["O" "X" "X"]], :piece "O", :board [["-" "-" "-"] ["-" "O" "-"] ["-" "X" "X"]]}
