Usage

It is now possible to represent playing cards with Unicode characters (Example: 🂻🂡🃌🃞)
You can learn more about the topic by reading this Wikipedia article
This library offers a way to obtain and interact with these characters
All value, suit and card parameters must be represented by strings

Here is a list of the different methods available in this library:

• Playing cards methods
  • Values and suits are strings that can be defined by their names ("Two", "jaCk", "sPaDE", "clubs", ...), their symbols ("2", "j", "♠", "♧", ...), or a card
  • They can be retrieved and redefined by modifying valuesName, valuesSymbol, suitsName and suitsSymbol
  • getPlayingCard(value, suit): Returns the icon of the corresponding card
  • isPlayingCard(card, includeJokers=false, includeTrumps=false, includeBack=false): Returns true if the input is a playing card
  • getValueName(value, digits=true): Returns the literal name of the corresponding value
  • getValueSymbol(value): Returns the symbol of the corresponding value
  • getSuitName(suit, plural=true): Returns the literal name of the corresponding suit
  • getSuitSymbol(suit, filled=true): Returns the symbol of the corresponding suit
• Jokers methods
  • getJoker(color="black"): Returns a joker card (The card can be black, white or red)
  • getJokerColor(joker): Returns the color of the corresponding joker
  • isJoker(joker): Returns true if the input is a joker card
• Trump cards methods
  • getTrumpCard(value): Returns a trump card from the corresponding value (between 0 and 21 inclusive, 0 representing the fool)
  • getTrumpCardValue(trump): Returns the value of a trump card
  • isTrumpCard(trump): Returns true if the input is a trump card
• Card back methods
  • getCardBack(): Returns a card back (🂠)
  • isCardBack(back): Returns true if the input is a card back

get methods will throw an error if the parameters are incorrect
Use is methods if you need to verify the parameters

Small example

var Cards = require('playing-card-icons');
var queen_of_hearts = Cards.getPlayingCard("Q", "hearts");
var spades = Cards.getSuitSymbol("spade"); // It doesn't matter if the name is in plural for suits

// Since cards can also work as values and suits, you can easily change the value or suit of a card
var queen_of_spades = Cards.getPlayingCard(queen_of_hearts, spades);
console.log(queen_of_hearts+" + "+spades+" = "+queen_of_spades);

// Generating a 52-card deck (excluding knights)
var deck = [];
for (const value of Cards.valuesName) {
	for (const suit of Cards.suitsName) {
		if (value !== "Knight") deck.push(Cards.getPlayingCard(value, suit));
	}
}
console.log(deck);
