A simple function using canvas to compress image file.

<input  type='file' id='test'/>
<script src="https://unpkg.com/frontend-image-compress@latest/dist/index.min.js"></script>
<script>
  const $file = document.querySelector('#test');
  $file.onchange = async function(e) {
    const file = e.target.files[0];
    window.Compress.compressImageFile(file).then(compressedFile=>{}).catch(err=>{
      alert(err.toString())
    })
  }
</script>

• yarn: yarn add frontend-image-compress
• npm: npm i frontend-image-compress

import { compressImageFile } from 'frontend-image-compress'

const $file = document.querySelector('#test');
$file.onchange = async function(e) {
  const file = e.target.files[0];
  const compressedFile = await compressImageFile(file)
}

when using script tag, you need to use window.Compress.xx, Compress is just a namespace
