The code needs a ES2015+ polyfill to work, for example regenerator-runtime/runtime.
require( 'regenerator-runtime/runtime' ) ;
// or
import 'regenerator-runtime/runtime.js' ;Then
const codecbase64 = require( '@aureooms/js-codec-base64' ) ;
// or
import * as codecbase64 from '@aureooms/js-codec-base64' ;
