React Anagram Animation

A React component to use CSS animations to swap letters in 2 words which are an anagram of each other.

The text is animated in position after calculating initial and final positions of each letter.

Install

yarn add react-anagram-animation

or

npm install react-anagram-animation

Usage

import React from 'react';
import Anagram from 'react-anagram-animation';

export default function MyComponent() {
    return (
        <Anagram words={['React Anagram Animation', 'Magenta Raincoat Airman']} />
    );
}

To control the animation speed and timing, you can pass an object of animationOptions.

<Anagram animationOptions={{
    randomStartMin: 0,
    randomStartMax: 0,
    randomReverseMin: 6000,
    randomReverseMax: 6000,
    loopAnimation: 20000,
    waitToStart: 5000,
    transitionDuration: 2000,
    timingFunction: 'ease-in-out',
}} />

If you are using an embedded font and need to wait for it to load before animating, then you should specify the fontToObserve property with the font family name.

<Anagram fontToObserve="Open Sans" />

<Anagram fontToObserve="Roboto" />

API

Props

Prop	Type	Default	Description
words	array	['React Anagram Animation', 'Magenta Raincoat Airman']	An array containing exactly 2 words which are an anagram of each other.
animationOptions	object	AnimationOptions	Timing options for when to start, how fast to animate forwards, backwards, and when to loop (optional).
fontToObserve	string		The name of an embedded font to wait until loaded. If not specified, animation will be loaded immediately (optional).

AnimationOptions

All time values are in # of milliseconds. The randomness allows a nice jumble effect. You can use any values you want to create some fascinating animations.

Property	Type	Default	Description
randomStartMin	number	0	The minimum amount of time to randomly wait before starting to animate each letter.
randomStartMax	number	3000	The maximum amount of time to randomly wait before starting to animate each letter. Should be >= randomStartMin.
randomReverseMin	number	6000	The minimum amount of time to randomly wait before starting to animate each letter in reverse.
randomReverseMax	number	9000	The maximum amount of time to randomly wait before starting to animate each letter in reverse. Should be >= randomReverseMin.
loopAnimation	number	12000	The amount of time to wait before starting the next full loop of the animation. Should be >= randomReverseMax + transitionDuration.
waitToStart	number	0	The amount of time to wait before beginning the animation on start up the first time.
transitionDuration	number	1000	How long should it take for a letter to move to its next position. Should be <= randomReverseMin - randomStartMax.
timingFunction	string	ease-in-out	What timing function should be used for the animation.

Run Locally

To run demo locally:

• yarn
• yarn start

and a browser will open to the demo.

If you receive Invalid hook call errors because you are linking this module, you may need to point this library's React to your app's installed React so there is only one copy.

npm link ../my-app/node_modules/react
npm link ../my-app/node_modules/react-dom

Future Ideas

• Animate between more than 2 words.
• Animate non-anagram words. Done.
