How to properly use raw-loader for React+WebPack?

Question

React

I want to import a text file into a variable. And for this I set:
"raw-loader": "^0.5.1",
But none of these options worked:

import cities from './cities.txt';
import cities from '!raw!./cities.txt';
import cities from '!raw./cities.txt';
import cities from 'raw!./cities.txt';

Either an error
Module not found: Can't resolve 'raw' in ...
. Either the path to the file is read, not its contents.
What am I doing wrong?
