Build Performance Warnings

[Antonio Ignacio Campos Ruiz]

In the build npm process output you get two warnings messages from webpack performance issues. This is the full message:

WARNING in asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).
This can impact web performance.
Assets:
  vendor.c2612e40.chunk.js (434 KiB)

WARNING in entrypoint size limit: The following entrypoint(s) combined asset size exceeds the recommended limit (244 KiB). This can impact web performance.
Entrypoints:
  bundle (456 KiB)
      vendor.c2612e40.chunk.js
      bundle.77a055c929b7e8b02f25.css
      bundle.6e20225a.js


WARNING in webpack performance recommendations:
You can limit the size of your bundles by using import() or require.ensure to lazy load some parts of your application.

I think it could be a performance improvement to resolve this by a new webpack implementation.

The number one reason the bundle is so large is because of corejs/stable:

You can optimize that if you know what exactly you need as it is described here

The other big factors are react-dom and i18next. If you don't need internationalization, you can remove it from the build and save a few more kilobytes.
