Critical dependency compile warning

[P1zz4br0etch3n]

I get this warning in dev mode every time I compile my react.js project:

./node_modules/defaultable/defaultable.js
49:13-31 Critical dependency: the request of a dependency is an expression

I created the project with create-react-app which setups the whole toolchain (babel, eslint, webpack) for me. Maybe it's interesting that I had to npm install dns and readline manually because they couldn't be resolved in the default setup.

Is it possible to make it compile without warning?
Thanks!
