The app shows how to use Firebase in your Aurelia application as well as Google Maps. The styling is done using Sass, Autoprefixer for browser prefixes and CSSNano for reducing CSS size. The app itself is actually quite simple.
To setup the app and run it yourself you will need to create yourself a free Firebase account and project, you will also need a Google Maps API key (also free). The database creation is automatic, you’ll also want to make sure in Firebase under auth you enable Facebook and Google if you want to allow both methods of login.
Feel free to make pull requests with new features, fixes and whatever. If they’re beneficial, they’ll get merged in to the actual site.
