Examples

Basic example

var app = document.getElementById('app');

var typewriter = new Typewriter(app, {
  loop: true,
  delay: 75,
});

typewriter
  .pauseFor(2500)
  .typeString('A simple yet powerful native javascript')
  .pauseFor(300)
  .deleteChars(10)
  .typeString('<strong>JS</strong> plugin for a cool typewriter effect and ')
  .typeString('<strong>only <span style="color: #27ae60;">5kb</span> Gzipped!</strong>')
  .pauseFor(1000)
  .start();

Custom text node creator using callback

var app = document.getElementById('app');

var customNodeCreator = function(character) {
  return document.createTextNode(character);
}

var typewriter = new Typewriter(app, {
  loop: true,
  delay: 75,
  onCreateTextNode: customNodeCreator,
});

typewriter
  .typeString('A simple yet powerful native javascript')
  .pauseFor(300)
  .start();

Custom handling text insert using input placeholder

var input = document.getElementById('input')

var customNodeCreator = function(character) {
  // Add character to input placeholder
  input.placeholder = input.placeholder + character;

  // Return null to skip internal adding of dom node
  return null;
}

var onRemoveNode = function({ character }) {
  if(input.placeholder) {
    // Remove last character from input placeholder
    input.placeholder = input.placeholder.slice(0, -1)
  }
}

var typewriter = new Typewriter(null, {
  loop: true,
  delay: 75,
  onCreateTextNode: customNodeCreator,
  onRemoveNode: onRemoveNode,
});

typewriter
  .typeString('A simple yet powerful native javascript')
  .pauseFor(300)
  .start();

React

This includes a React component which can be used within your project. You can pass in a onInit function which will be called with the instance of the typewriter so you can use the typewriter core API.

import Typewriter from 'typewriter-effect';

<Typewriter
  onInit={(typewriter) => {
    typewriter.typeString('Hello World!')
      .callFunction(() => {
        console.log('String typed out!');
      })
      .pauseFor(2500)
      .deleteAll()
      .callFunction(() => {
        console.log('All strings were deleted');
      })
      .start();
  }}
/>

Alternatively you can also pass in options to use auto play and looping for example:

import Typewriter from 'typewriter-effect';

<Typewriter
  options={{
    strings: ['Hello', 'World'],
    autoStart: true,
    loop: true,
  }}
/>
