A small library for creating typing animations.

View a short video demonstration here.

Installation

npm i tiper-js

Usage

Initialization is really simple. Just create a new instance of Tiper and pass in a DOM element. The options object is optional.

//ES6
import Tiper from "tiper-js";

//ES5
let Tiper = require('tiper-js');

let tiper = new Tiper(document.querySelector('.tiper-js-container'));

tiper.beginTyping(); //Begins typing with default text and config.
tiper.line('Hello, neighbor!') // Types "Hello, neighbor!". Also uses default config.

If you want to have the blinking cursor affect, link the css file in your html file like so:

<link type="text/css" rel="stylesheet" href="./node_modules/tiper-js/lib/tiper-js.css">

Checkout the test folder for a basic, viewable example.

Options

Tiper exposes a minimal, yet fun, set of options to play around with.

• text: string (required) - The string of text to be typed.
• hesitation: number - A number from 0 to 1. Used as a factor in determining the delay between typing the next character. Default is 0.45.
• wordsPerMinute: number: - A number used to determine typing speed. Default is 40.
• pauseTimeout: number: - The time in ms to pause on certain conditions. Only applies if pauseOnSpace or pauseOnEndOfSentence is true.
• pauseOnSpace: boolean: - Whether or not to pause on spaces. Default is false.
• pauseOnEndOfSentence: boolean: - Whether or not to pause at the end of sentences. Default is true.
• showCaret: boolean: - Whether or not show caret. Default is false.
• caretType: string: - The type of caret to show if showCaret is true. Available options are 'normal' or 'underscore'. Default is 'normal'.
• glitch: boolean: - Whether or not to show glitch effect intermittently.
• onFinishedTyping: Function: - The callback to fire after the text has been typed.

Methods

• typer.beginTyping(text: string, reset: boolean) - Begin typing at the current index. Returns a Promise that resolves when all the text has been typed.
• typer.stopTyping() - Stop typing at the current index. Returns a Promise that resolves when async interval is cleared.
• typer.line(text: string) - Output a single line of text. Returns a Promise that resolves when the particular text is finished being displayed.
