poker-js

A convenience library for writing poker related programs, written in JavaScript.

Provides the following objects in the POKER namespace.

• Deck
• Card
• Hand

and the function POKER.getWinners(hands)

Including in your code

As a node module:

1. clone the repo or download poker.js

2. include the POKER object into your code

   var POKER = require('path/to/poker.js').POKER;

In a browser application:

<script src="https://github.com/sbnb/poker-js/raw/master/path/to/poker.js"></script>

Either way the POKER namespace is created.

Usage

Create some specific hands

var tripAces = POKER.handFromString('As Ah Ad Ks 3c'),
    flush = POKER.handFromString('7s 6s As Ks 3s'),
    straight = POKER.handFromString('7s 6s 4c 3h 5s'),
    lowStraight = POKER.handFromString('As 2s 4c 3h 5s');

var winner = POKER.getWinners([tripAces, flush, straight, lowStraight]);
// winner == [flush]

winner = POKER.getWinners([flush, straight]);
// winner == [flush]

winner = POKER.getWinners([lowStraight, straight]);
// winner == [straight]

Deal some hands from a deck

var deck = new POKER.Deck(),
    hands = [];

for (var idx = 0; idx < 6; idx += 1) {
    hands[idx] = new POKER.Hand(deck.deal(5));
};

// find the winner/s
var winner = POKER.getWinners(hands);
