How to use

const fs = require('fs')
const { ImageProcessor } = require('sharp-mozjpeg-image-processor')

const processor = new ImageProcessor()

const srcStream = fs.createReadStream('./source.jpg')
const imgInfos = [
  {
    kind: 'large',
    width: 1200,
    height: 1200,
  },
  {
    kind: 'small',
    width: 800,
    height: 800,
  },
  {
    kind: 'thumb',
    width: 400,
    height: 400,
    crop: true, // cover for example thumbnail
  }
]
const quality = 70 // default 80 for jpeg image quality

processor.execute(srcStream, imgInfos, quality)
.then(outImgInfos => {
  for (let outImgInfo of outImgInfos) {
    console.log(outImgInfo)
  }
})
