Not able to convert images to WebP using imagemin-webp

same problem here

try this:

const imagemin = require('imagemin');
const imageminWebp = require('imagemin-webp');

imagemin(['images/*.{jpg,png}'], {
  destination: __dirname + '/images/converted/',
  plugins: [
    imageminWebp({
      quality: 75,
      resize: {
        width: 1000,
        height: 0
      }
    })
  ]
}).then(() => {
  console.log('Images optimized');
});

you can leave out the resize portion of course;
if one part of the resize parameters is 0 it uses the original ratio (for 2:3 images if you enter 1000 it gets 1000x1500);

i still have no clue how to convert single images...
this is highly cryptic and not well documented despite having over 300k downloads per week on npm;
