View the Live Demo | View All Demos | View Full Docs | mattboldt.com

Typed.js is a library that types. Enter in any string, and watch it type at the speed you've set, backspace what it's typed, and begin a new sentence for however many strings you've set.

Installation

NPM

npm install typed.js

Yarn

yarn add typed.js

Bower

bower install typed.js

Setup

This is really all you need to get going.

// Can also be included with a regular script tag
import Typed from 'typed.js';

var options = {
  strings: ["<i>First</i> sentence.", "&amp; a second sentence."],
  typeSpeed: 40
}

var typed = new Typed(".element", options);

Strings from static HTML (SEO Friendly)

Rather than using the strings array to insert strings, you can place an HTML div on the page and read from it. This allows bots and search engines, as well as users with JavaScript disabled, to see your text on the page.

<script>
  var typed = new Typed('.element', {
    stringsElement: '#typed-strings'
  });
</script>

<div id="typed-strings">
    <p>Typed.js is a <strong>JavaScript</strong> library.</p>
    <p>It <em>types</em> out sentences.</p>
</div>
<span id="typed"></span>

Type Pausing

You can pause in the middle of a string for a given amount of time by including an escape character.

var typed = new Typed(".element", {
  // Waits 1000ms after typing "First"
  strings: ["First ^1000 sentence.", "Second sentence."]
});

Smart Backspacing

In the following example, this would only backspace the words after "This is a"

var typed = new Typed(".element", {
  strings: ["This is a JavaScript library", "This is an ES6 module"],
  smartBackspace: true // Default value
});

Bulk Typing

The following example would emulate how a terminal acts when typing a command and seeing its result.

var typed = new Typed(".element", {
  strings: [
    "git push --force ^1000\n `pushed to origin with option force`"
  ]
});

CSS

CSS animations are build upon initialzation in JavaScript. But, you can customize them at your will! These classes are:

/* Cursor */
.typed-cursor {}

/* If fade out option is set */
.typed-fade-out {}

Use with ReactJS

Check out this example React app using Typed.js in a component: https://jsfiddle.net/mattboldt/ovat9jmp/
