Using LocalTunnel: Testing on a Server
While you are able to log in and log out with the application running on localhost, many of the activities require that the assets they reference be accessible from the open web. There are a couple ways to deal with this in development: You can run your app on a server or you can use a tool like LocalTunnel.
LocalTunnel is a free service that allows you to expose a port on your localhost to the web at large. It’s not meant to run a production site but is merely a quick way to verify a flow or show someone a test build. You can find more information on how to install and use LocalTunnel at http://progrium.com/localtunnel/.
