The sample didn't work for me.
Got it working this way for node v12.9.1

const mediainfolib = require('./mediainfo.js');
const parser = require('xml2json');
const fs = require('fs');

export default {

  mi: undefined,

  create: async function () {
    // some weird bug in the mediainfo.js library
    const oldReadFileSync = fs.readFileSync;
    fs.readFileSync = function (filename) {
      if (filename === 'mediainfo.js.mem')
        return oldReadFileSync.call(this, require.resolve('mediainfo.js') + '.mem');
      else return oldReadFileSync.apply(fs, arguments);
    };

    const lib = mediainfolib();

    // CHANGED THIS HERE
    this.mi = await new Promise(function (resolve, reject) {
      lib.then(x => resolve(new x.MediaInfo()));
    });

    return this;
  },

  extract: function (buffer) {
    const fileSize = parseInt(buffer.byteLength);
    const offset = 0;

    this.mi.open_buffer_init(fileSize, offset);
    this.mi.open_buffer_continue(buffer, fileSize);
    const xmlResult = this.mi.inform();
    this.mi.close();

    return parser.toJson(xmlResult, { object: true });
  }
};
