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,
}} />

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

<Anagram fontToObserve={{ family: 'Open Sans' }} />

<Anagram fontToObserve={{
    family: 'Roboto',
    weight: 600,
    style: 'italic',
    stretch: 'expanded',
}} />
