Installation

npm install yordle
# or
yarn add yordle

Quick Start

import yordle from 'yordle';

// Initialize the game
const game = yordle({
  word: 'hello',    // Target word
  wordSize: 5,      // Word length
  wordList: ['hello', 'world'], // Custom word list
  entries: []       // Previous game entries
});

// or

const game = yordle(); // Use the default values
const word = game.draw(true); // Generate a random word to guess

// Make a guess
const result = game.guess('world');
console.log(result);
// Output: [
//   { w: 'wrong' },
//   { o: 'exists' },
//   { r: 'wrong' },
//   { l: 'exact' },
//   { d: 'wrong' }
// ]

API Reference

yordle(props: YordleProps)

Main function to initialize the game controller.

Props

type YordleProps = {
  word?: string;          // Optional: Put a custom word or generate using draw(true) function
  wordSize?: number;      // Optional: Length of the word (Defaults to 5)
  wordList?: string[];    // Optional custom word list (Defaults to a 5-letter word list)
  entries?: ResultType[]; // Optional previous game entries
}

Returns

Object containing the following methods:

guess(input: string): ResultType

Makes a guess with the provided input word and returns the result.

• Parameters:
  • input: The word guessed by the player
• Returns: Array of objects containing letter matches:
  • 'exact': Letter is in correct position
  • 'exists': Letter exists in word but wrong position
  • 'wrong': Letter does not exist in word

const result = game.guess('spark');
// Example output:
// [
//   { s: 'wrong' },
//   { p: 'exists' },
//   { a: 'wrong' },
//   { r: 'exact' },
//   { k: 'wrong' }
// ]

draw(overwrite?: boolean): string

Returns a random word from the word list.

• Parameters:
  • overwrite: If true, replaces the current target word (default: false)
• Returns: A random word from the word list

const newWord = game.draw();        // Get random word
const newTarget = game.draw(true);  // Get and set new target word

verify(input: string): boolean

Verifies if a word exists in the word list.

• Parameters:
  • input: Word to verify
• Returns: Boolean indicating if the word is valid

const isValid = game.verify('hello'); // true

Types

type MatchType = 'exact' | 'exists' | 'wrong';

type ResultType = Array<{
  [letter: string]: MatchType
}>;

type LetterCountType = {
  [letter: string]: number
} | object;

Example Usage

Basic Game Implementation

import yordle from 'yordle';

// Initialize game
const game = yordle();
const word = game.draw(true);

// Process player guess
function handleGuess(playerInput: string) {
  if (!game.verify(playerInput)) {
    console.log('Invalid word!');
    return;
  }

  const result = game.guess(playerInput);
  
  // Check for win condition
  const isWin = result.every(letterResult => 
    Object.values(letterResult)[0] === 'exact'
  );

  if (isWin) {
    console.log('Congratulations!');
  }

  return result;
}

Custom Word List

const customGame = yordle({
  wordSize: 4,
  wordList: ['code', 'java', 'rust', 'ruby', 'perl'],
});
const word = customGame.draw(true);
