My answer is similar to Alex's. I'm not sure why React-Router made this so needlessly complicated. Why should I have to wrap my component with a HoC just to get access to what's essentially a global?

Anyway, if you take a look at how they implemented <BrowserRouter>, it's just a tiny wrapper around history.

We can pull that history bit out so that we can import it from anywhere. The trick, however, is if you're doing server-side rendering and you try to import the history module, it won't work because it uses browser-only APIs. But that's OK because we usually only redirect in response to a click or some other client-side event. Thus it's probably OK to fake it:

// history.js
if(__SERVER__) {
    module.exports = {};
} else {
    module.exports = require('history').createBrowserHistory();
}

With the help of webpack, we can define some vars so we know what environment we're in:

plugins: [
    new DefinePlugin({
        '__SERVER__': 'false',
        '__BROWSER__': 'true', // you really only need one of these, but I like to have both
    }),

And now you can

import history from './history';

From anywhere. It'll just return an empty module on the server.

If you don't want use these magic vars, you'll just have to require in the global object where it's needed (inside your event handler). import won't work because it only works at the top-level.
