Usage

Creating a deck

When creating a deck, you must provide a generic parameter TCard. This indicates the type of card within the deck.

import { CardDeck } from "@shoki/card-deck";

type Card = {
	value: number;
	suit: string;
};

const deck = new CardDeck<Card>();

Adding cards

You can add a card, or cards, to the deck with the addCards function.

There is an optional boolean parameter shouldShuffle (which defaults to true) to indicate whether the deck should be shuffled (with the shuffle function described below) immediately after the addition.

// Add a single card
deck.addCards({ value: 1, suit: "hearts" });

// Add a card without shuffling
deck.addCards({ value: 2, suit: "hearts" }, false);

// Add multiple cards
deck.addCards([
	{ value: 3, suit: "hearts" },
	{ value: 4, suit: "hearts" },
]);

// Add multiple cards without shuffling
deck.addCards(
	[
		{ value: 3, suit: "hearts" },
		{ value: 4, suit: "hearts" },
	],
	false
);

Taking cards

You can take a card, or multiple cards, from the deck with the take function.

// Take a single card
const card = deck.take();

// Take multiple cards
const cards = deck.take(2);

Shuffling the deck

This uses the Fisher-Yates shuffle through lodash.shuffle.

// Shuffle the deck
deck.shuffle();
