Transforms images in a directory to perfect squares.

npm i squarifier or yarn add squarifier

If you want to squarify all of the images in a given directory with a max size of 1200 pixels and fill the margin with a black background color, you can do the following:

let squarifier = require('squarifier');

squarifier('path/to/img/folder', 1200, 0x000000FF)
  .catch(err => {
    console.log(err);
  }).then((counter) => {
    console.log(`Done. Changed ${counter} files.`);
  });

node path/to/squarifier/index.js -d path/to/img/folder -s 1200 -c 0x000000FF
