Webpack 4.16.2 - Critical dependencies - the request of a dependency is an expression

See original GitHub issue

With Webpack 4.16.2 this import cause a critical dependencies warning: import universal from 'react-universal-component'

With Webpack 4.8.0 works fine. I suppose this is the cause:

https://github.com/webpack/webpack/releases/tag/v4.16.2 handle module.require like require

In utils.js i found a module.require.

Can you investigate about this? Thanks for your work!

We might be able to work around it by treating as a string

‘let Module = require(${url});’

Yaaaaay!

Okay I’ll merge it tonight or tomorrow.

Heads up, there’s a React 16 rewrite on the way. It will be RUC 4 but I plan to support RUC 3 for a while ❤️

Thrilled these damn errors are gone.
