+    ...
+    if (token != null) {
+      // for Spring Boot back-end
+      // authReq = req.clone({ headers: req.headers.set(TOKEN_HEADER_KEY, 'Bearer ' + token) });
 
-Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
+      // for Node.js Express back-end
