[javascript] Resize image with javascript canvas (smoothly)

I wrote small js-utility to crop and resize image on front-end. Here is link on GitHub project. Also you can get blob from final image to send it.

import imageSqResizer from './image-square-resizer.js'

let resizer = new imageSqResizer(
    'image-input',
    300,
    (dataUrl) => 
        document.getElementById('image-output').src = dataUrl;
);
//Get blob
let formData = new FormData();
formData.append('files[0]', resizer.blob);

//get dataUrl
document.getElementById('image-output').src = resizer.dataUrl;
