React Typing Game Hook

Easily create typing games functionalty (10fastestfinger, monkeytype, keybr, etc) with this react hook that handles the typing logic

About

This hook takes care of the states and the little details that goes on when users type in a typing game/test/challenge! Your part is to just capture the inputs from the user!

Getting Started

Importing

npm install react-typing-game-hook

yarn add react-typing-game-hook

Usage

Here's a simple example of it (live here)

import React from 'react';
// import it
import useTypingGame, { CharStateType } from 'react-typing-game-hook';

const TypingGameComponent = () => {
  // Call the hook
  const {
    states: { chars, charsState },
    actions: { insertTyping, resetTyping, deleteTyping },
  } = useTypingGame('Click on me and start typing away!');

  // Capture and display!
  return (
    <h1
      onKeyDown={e => {
        e.preventDefault();
        const key = e.key;
        if (key === 'Escape') {
          resetTyping();
          return;
        }
        if (key === 'Backspace') {
          deleteTyping(false);
          return;
        }
        if (key.length === 1) {
          insertTyping(key);
        }
      }}
      tabIndex={0}
    >
      {chars.split('').map((char, index) => {
        let state = charsState[index];
        let color =
          state === CharStateType.Incomplete
            ? 'black'
            : state === CharStateType.Correct
            ? 'green'
            : 'red';
        return (
          <span key={char + index} style={{ color }}>
            {char}
          </span>
        );
      })}
    </h1>
  );
};
export default TypingGameComponent;

Structure Breakdown

const {
  states: {
    startTime,
    endTime,
    chars,
    charsState,
    length,
    currIndex,
    currChar,
    correctChar,
    errorChar,
    phase,
  },

  },
} = useTypingGame(text, {
  skipCurrentWordOnSpace: true,
  pauseOnError: false,
  countErrors: 'everytime',
});

Enumeration Breakdown

import { PhaseType, CharStateType } from 'react-typing-game-hook';

PhaseType {
  NotStarted = 0,
  Started = 1,
  Ended = 2,
}

CharStateType {
  Incomplete = 0,
  Correct = 1,
  Incorrect = 2,
}

Hook Parameters

Name	Functionalty	Default value
skipCurrentWordOnSpace	When `true`, moves on to the next word when space is inputted. Otherwise, it moves on to the next character instead	`true`
pauseOnError	When `true`, stays on the same character until it is correctly inputted. Otherwise, it moves on to the next character instead	`false`
countErrors	When value is `'everytime'`, count errors anytime a mistake is made. When value is `'once'`, count errors only once for each mistake made at the position where the letter is typed.	`'everytime'`

Hook States

Name	Functionalty	Data Type	Initial value
startTime	Time in milliseconds (since the Unix Epoch) when the typing started.	`number`	Prior to when the typing starts, it is `null`
endTime	Time in milliseconds(since the Unix Epoch) when the typing test ended.	`number`	Prior to when the typing ended, it is `null`
chars	The inputted text to be used for typing.	`string`	-
length	The lengh of the inputted text	`number`	Length of the inputted text `chars`
charsState	Array of each character's state of the inputted text. Each item represents the corresponding chararacter of the text inputted. `CharStateType.Incomplete` - has yet to be determined to be correct or incorrect `CharStateType.Correct` - is determined to be correct `CharStateType.Incorrect` - is determined to be incorrect.Use of `CharStateType` over numeric literal is recommended	`CharStateType[]`	Array length of `chars` filled with `CharStateType.Incomplete`
currIndex	Current character index of the text the user have typed till.	`number`	-1
currChar	Current character the user have typed till.	`string`	''
correctChar	Number of correct character the user had typed.	`number`	0
errorChar	Number of incorrect character the user had typed.	`number`	0
phase	Represent the current state of the typing test. `PhaseType.NotStarted` - typing haven't started `PhaseType.Started` - typing started `PhaseType.Ended` - typing ended Use of `PhaseType` over numeric literal is recommended	`PhaseType`	`PhaseType.NotStarted`

Hook Methods

Name	Functionalty	Signature	Return value
insertTyping	Insert a character into the current typing sequence. It will start the typing if it hasn't been started as well as end the typing for you when the last character has been entered.	`insertTyping(char:string)`	-
deleteTyping	It only works when the typing has been started. Allows for the current word in the typing sequence to be deleted when passed with a parameter of `true`, otherwise it deletes only a character from the current typing (default behavior).	`deleteTyping(deleteWord?: boolean)`	-
resetTyping	Reset to its initial state.	`resetTyping()`	-
endTyping	Ends the current typing sequence if it had started. States persist when ended and `endTime` is captured.	`endTyping()`	-
setCurrIndex	Set the current index manually. Only works when `phase` is `PhaseType.NotStarted` (haven't started typing) or `PhaseType.Started` (during typing).	`setCurrIndex(index:number)`	`true` if successfull, otherwise `false`
getDuration	Duration in milliseconds since the typing started.	`getDuration()`	`0` if the typing has yet to start.
