A simple component to create a typewriter effect where strings are typed out and then deleted. Simply pass in an array of strings and the component will rotate through all of them.

Demo & Examples

Live demo: adrianmcli.github.io/react-rotating-text

To build the examples locally, run:

npm install npm start

Then open localhost:8000 in a browser.

Installation

The easiest way to use react-rotating-text is to install it from NPM and include it in your own React build process (using Browserify, Webpack, Brunch, etc).

You can also use the standalone build by including dist/react-rotating-text.js in your page. If you use this, make sure you have already included React, and it is available as a global variable.

npm install react-rotating-text --save

Usage

Simply require the component and then pass in an array of strings into the items prop:

var ReactRotatingText = require ( ' react-rotating-text ' ) ; < ReactRotatingText items = { [ ' first ' , ' second ' , ' third ' ] } />

In order to have a blinking cursor, you'll need to apply some CSS to the react-rotating-text-cursor class:

. react-rotating-text-cursor { animation : blinking-cursor 0.8 s cubic-bezier ( 0.68 , 0.01 , 0.01 , 0.99 ) 0 s infinite ; } @ keyframes blinking-cursor { 0% { opacity : 0 ; } 50% { opacity : 1 ; } 100% { opacity : 0 ; } }

Don't forget to put in vendor prefixes should you need them. A full example is available in example/dist/ReactRotatingText.css .

Events

onTypingStart

A callback function to call when typing starts for current item.

Notes

Enhancements and pull requests are welcomed.

Development ( src , lib and the build process)

NOTE: The source code for the component is in src . A transpiled CommonJS version (generated with Babel) is available in lib for use with node.js, browserify and webpack. A UMD bundle is also built to dist , which can be included without the need for any build system.

To build, watch and serve the examples (which will also watch the component source), run npm start . If you just want to watch changes to src and rebuild lib , run npm run watch (this is useful if you are working with npm link ).
