Use npm install to install the dependencies
The server can be started like:
node server.js 5050
Once the server started, it will listen on the specified port (5050) for clients to connect.
The client will be started like:
node client.js 127.0.0.1 5050
The client will connect to the server at the specified IP (127.0.0.1) and port (5050). Upon connection the client will display a message and prompt, like:
connected to 127.0.0.1 5050
>
When two clients have connected to the server, the game will begin. The server will send each client the message:
Game started. You are the [first | second] player.
The first player can then send a move like:
> 5
This move would place an ‘X’ at square number 5.
The Tic-Tac-Toe board is numbered like this:
| 1 | 2 | 3 |
|---|---|---|
| 4 | 5 | 6 |
| 7 | 8 | 9 |
When the move is accepted by the server, it sends the current board position to both clients, like:
| . | . | . |
|---|---|---|
| . | X | . |
| . | . | . |
Let’s say the second player make the move:
> 9
Both clients would then receive the new board position of:
| . | . | . |
|---|---|---|
| . | X | . |
| . | . | O |
Either player can resign the game at anytime, by sending ‘r’. When the game is over, the server sends both players a result message, like:
Game won by [first | second] player.
Or
Game is tied.
The clients close the connection to the server after the game is over. The clients can connect again to play another game.
