Overview

TypeIt is the most versatile JavaScript animated typing utility on the planet. With simple, straightforward configuration, it allows you to type single or multiple strings that break lines, delete & replace each other, and it even handles strings that contain HTML.

For more advanced, controlled typing effects, TypeIt comes with companion functions that can be chained to control your typing down to a single character, enabling you to type an dynamic narrative, with complete control over speed changes, line breaks, deletions, and pauses.

Some of the Perks

Choose to start typing only when your container element becomes visible on the screen.
Loop your string(s) continuously.
Define you strings via an options object or in the HTML (useful in case user doesn't have JavaScript enabled, as well as for SEO).
Use a single TypeIt instance to control several different elements on a page.
Handle HTML tags (including those with classes, ID's, etc.) and entities with ease.
Use companion functions to chain individual commands together to fine tune your typing.
Ready to be included via JS module, or as a separate script loaded on your page.
No dependencies!

Usage

Get the Code

CDN: Include https://cdn.jsdelivr.net/npm/typeit@VERSION_NUMBER/dist/typeit.min.js on your page.
npm / yarn: Install with npm install typeit or yarn install typeit and import into your project with import TypeIt from 'typeit'.
Build It Yourself: If, for some weird reason, you want to clone the repository and build the code yourself, first run yarn install and then yarn run build. The compiled source files will be in the /dist directory.

Hook It Up

Load TypeIt into your page or application.

<script src="typeit.min.js"></script>

import TypeIt from 'typeit';

Create an empty HTML element to select. (If you want to have a fallback for users without JavaScript, you can put a string or strings right into this element. For more on that, see the full documentation.)

<span class="type-it"></span>

You're ready to start typing!

Simple Usage

At its simplest use, just create a new TypeIt instance, pass an empty element, and define your options.

Example:

  new TypeIt('.type-it', {
    strings: ['Enter your string here!', 'Another string!']
  });

Advanced Usage

To control a typewriter effect to the smallest character, pause, speed, or more, there are six companion functions available. Simply chain them together on an instance of TypeIt, and your chain will execute. You'll be able to create a dynamic, realistic narrative with just a few lines of code.

For example:

  new TypeIt('.type-it', {
    speed: 900,
    lifeLike: false,
    autoStart: false
  })
  .type('I am typing slowly,')
  .options({speed: 100})
  .type('but now I am typing pretty fasst')
  .delete(2)
  .type('t!');

To view these functions and how they work, see the API section.

Options

Defining Your Options

You can modify the options for the plugin by passing in JSON.

There are a number of options you may use to customize TypeIt. For more details on these options, view the full documentation.

Option	Description	Default Value
strings	(string or array) The string(s) to be typed.	'Your default string.'
speed	(number in millseconds) The typing speed.	100
deleteSpeed	(number in millseconds) The deletion speed. If left undefined, will be 1/3 of the type speed.	undefined
lifeLike	(boolean) Will make the typing pace irregular, as if a real person is doing it.	true
cursor	(boolean) Show a blinking cursor at the end of the string(s).	true
cursorSpeed	(number in milliseconds) The blinking speed of the cursor.	1000
breakLines	(boolean) Choose whether you want multiple strings to be printed on top of each other (`breakLines: true`), or if you want each string to be deleted and replaced by the next one (`breakLines: false`).	true
nextStringDelay	(number in milliseconds) The amount of time (milliseconds) between typing the next string when multiple strings are defined.	750
startDelete	(boolean) Whether to begin instance by deleting strings inside element, and then typing what strings are defined via JSON or companion functions.	false
startDelay	(number in milliseconds) The amount of time before the plugin begins typing after initalizing.	250
loop	(boolean) Have your string or strings continuously loop after completing.	false
loopDelay	(number in milliseconds) The amount of time between looping over a string or set of strings again.	750
html	(boolean) Handle strings as HTML, which will process tags and HTML entities. If 'false,' strings will be typed literally.	true
callback	(function) A function that executes after your typing has completed.	nuthin'

Changing Option Defaults

If you're creating several instances of TypeIt on a page, and don't wish to repeatedly set an option of the same value for each of them, you can redefine the default options beforehand. Change the default value(s) before creating any instances, and you'll be set.

    window.TypeItDefaults.speed = 50;

    //-- This and all following instances will now have a default speed of 50.
    new TypeIt('#id', {
        strings: 'A string!'
    });

Companion Functions

Use these functions to chain typing commands together upon initialization.

Function	Arguments	Description
type()	(string) Characters (including those wrapped in HTML) to be typed.	Will type the characters.
delete()	(number) Number of characters to be deleted from what's already been typed.	Will delete the specified number of characters.
empty()	(none)	Will instantly delete everything that has already been typed.
pause()	(number) Number of milliseconds to pause before continuing.	Will pause the specified number of milliseconds.
break()	(none)	Will break the typing to a new line.
options()	(JSON) Options you'd like to update	Will redefine your options on the fly. This will only work for updating the `speed`, `lifeLike`, and `html` options.

Other Handy Functions

Destroy an Instance

Function	Arguments	Description
destroy()	(bool) Whether you want to remove the cursor after destroying. Default is `true`.	Destroys the instance on whatever elements to which it's attached.

var instance = new TypeIt('#id', {
    strings: 'This is my string'
});

//-- Will preserve the cursor. If you want to destory that too, pass 'false'.
instance.destroy();
