• try importing jQuery before using wowjs – Radinator Commented Apr 13, 2017 at 12:29
• I already did it – Ali Turki Commented Apr 13, 2017 at 12:31
• Ya, I think it would be tough to get a jQuery.Deferred exception if you didn't have jQuery yet. – takendarkk Commented Apr 13, 2017 at 12:33
• Try var Wow = require('wowjs').default; – Linus Borg Commented Apr 13, 2017 at 12:40
• it still doesn't work – Ali Turki Commented Apr 13, 2017 at 12:46

try this one

const WOW = require('wowjs');

window.wow = new WOW.WOW({
    live: false
});

window.wow.init();

the module exports an object, you need to use the WOW constructor in that object. Eg. require('wowjs').WOW

You need to use wow.js instead of wowjs in React

npm install wow.js

and in your code

import WOW from 'wow.js'

useEffect(() => {
    const wow = new WOW({ live: false }) // disables sync requirement
    wow.init()
}, [])
