TypeError: __WEBPACK_IMPORTED_MODULE_7_jquery___default(...)(...).vegas is not a function

[MuhammadHasham23]

This is what i am doing,

import $ from 'jquery';
import vegas from 'vegas';
class Home extends Component {
	constructor(props) {
		super(props);
	}
	componentDidMount() {
		$('.container-fluid').vegas({
			slides: [
				{
					src: '..assets/images/theme_images/background-image-overlay-full.png'
				}
			]
		});
	}

[zackschuster]

did you ever solve this issue? i've had some experience with this error, so i might be able to provide some useful info.

No. It didn't worked for me.

@MohammadHasham This is how I managed to make it work with create-react-app

1. I have copy the original js into my directory lib folder
2. then imported

import jquery from 'jquery';`

3. after simple modification it will look like below
4. then I imported in to my component like this

import '../../libs/vegas';

Modified vages.js

import jquery from 'jquery';
