react-hot-boilerplate VS react-redux-universal-hot-example

Let me preface this by saying that everything I have set up works, this is just a question that's nagging me that I would love to get an answer for. I'm using the react-hot-boilerplate project (https://github.com/gaearon/react-hot-boilerplate). However, in webpack.config.js, this setting is confusing me to no end:

I am developing an app based in this React Redux boilerplate. In one component I need to get the current URL when component is mounted in order to generate a shareable URL for social media. Than component is being accesible from dynamically generated URLs with React Router. In client side I wouldn't have any problem by getting it through javascript document object but the problem lies server side.

export default class ApiClient { constructor(req) { /* eslint-disable no-return-assign */ methods.forEach((method) => this[method] = (path, withCredentials, { params, data } = {}) => new Promise((resolve, reject) => { const request = superagent[method](formatUrl(path)) if (withCredentials) { console.log('first of all, its true') console.log(this) } if (params) { request.query(params) } if (__SERVER__ && req.get('cookie')) { request.set('cookie', req.get('cookie')) } if (data) { request.send(data) } request.end((err, { body } = {}) => { return err ? reject(body || err) : resolve(body) }) })) /* eslint-enable no-return-assign */ } /* * There's a V8 bug where, when using Babel, exporting classes with only * constructors sometimes fails. Until it's patched, this is a solution to * "ApiClient is not defined" from issue #14. * https://github.com/erikras/react-redux-universal-hot-example/issues/14 * * Relevant Babel bug (but they claim it's V8): https://phabricator.babeljs.io/T2455 * * Remove it at your own risk. */ empty() {}} I want to connect this to my auth so that I can prepend headers to protected endpoints, like so:
