LoR Deckcodes

This is a TypeScript port of the Legends of Runeterra deck encoder/decoder. The goal of this project is to keep up-to-date with Riot's Implementation, stay as close to the original source code as possible, and use zero external runtime dependencies.

Installation

npm i lor-deckcodes-ts

Usage

import { 
   getCodeFromDeck, 
   getDeckFromCode, 
   CardCodeAndCount, 
   Deck 
} from 'lor-deckcodes-ts';

// convert a deck code into a Deck / CardCodeAndCount[]
const code: string =
   'CEBQGAIFAMJC6BABAMCBGFJUAICAGAQRAICACBIWDQOS4AIBAM4AEAIEAUIQEBADAEHQ';

const decodedDeck: Deck = getDeckFromCode(code);
