Import ECMA substitute

[Remonell]

Hi,
when I start my PWA with 'ionic serve' I get the following warning in the browser console:

node_modules\ionic-logging-service\fesm2015\ionic-logging-service.js depends on 'log4javascript'. CommonJS or AMD dependencies can cause optimization bailouts.
For more info see: https://angular.io/guide/build#configuring-commonjs-dependencies

I read that you have to import it with a ECMA friendly substitute or just disable the warning for that package. Can you somehow provide an ECMA friendly substitute to your package?

Kind regards
