function getBase64(file) {
return new Promise((resolve, reject) => {
const reader = new FileReader();
reader.readAsDataURL(file);
reader.onload = () => resolve(reader.result);
reader.onerror = error => reject(error);
});
}
var file = document.querySelector('#files > input[type="file"]').files[0];
getBase64(file).then(
