Callback to Async Await

Question

I have been trying to use this library: https://github.com/xkeshi/image-compressor

example from there:

new ImageCompressor(file, {
    quality: .6,
    success(result) {
      ...
    },
    error(e) {
      ...
    },
  });

I want to wrap this function inside an async function called compress to use it like:

const compressed file = await compress(file)

And what did you tried...? – Alex Michailidis Apr 12 '18 at 15:25 — Alex Michailidis, Apr 12 '18 at 15:25

  function compress(file) {
    return new Promise((resolve, reject) => {
       new ImageCompressor(file, {
         quality: .6,
         success: resolve,
         error: reject
      });
   });
 }

You can simple wrap the function like this:

  function compress(parameters) {
      return new Promise((resolve,reject) => {
        new ImageCompressor(file, {
          quality: .6,
          success(result) {
            resolve(result)
          },
          error(e) {
            reject(e)
          },
        });
     })
