If you run the app now, you'll see the Firebase user ID in the console log after a login, which will be used later to index profile data in Firestore.Īdding some animation will smooth out the transitions between the login page states. The isInitialized flag will be toggled once firebase is initialized and ready for the app to login with. = (TNS_ENV = 'production')Ĭonsole.log((data.loggedIn ? "Logged in to firebase" : "Logged out from firebase") + " (firebase.init() onAuthStateChanged callback)") Ĭonsole.log("firebase.init error: " + error) Vue.prototype.$backendService = backendService Import LoginPage from './components/LoginPage'Įxport const backendService = new BackendService()Įxport const authService = new AuthService()
Import AuthService from './services/AuthService' Import BackendService from './services/BackendService' Import firebase from "nativescript-plugin-firebase" Import VueDevtools from 'nativescript-vue-devtools' Now change /app/main.js so that the AuthService class can be accessed anywhere in the app. Then edit export default from 'tns-core-modules/application-settings' I'll add a new local state variable isInitialized with an initial value of false, and then add v-show directives based on this flag to hide all login page elements except for the logo, app title and the new loader text Label and ActivityIndicator spinner.Įdit LoginPage.vue so the template XML now contains:
The current login page will be changed to show just the app logo, some text and a spinner until Firebase initialization completes.

Let's install the VueX library: npm i vuex -save The application can then trigger actions when there are changes in state, such as when logged in or out of the application. The VueX state management library will be used to manage state across different Vue pages. I'll modify the nsvfblogin app into a usable skeleton app with a personalized home page and working profile page using various Firebase services. Whenever the user is logged out from Firebase, the app should to route to the login page. If a user is already logged in with Firebase, any further calls necessary should be made before routing to the home page of the app. Until then, the app can display a loading screen while Firebase initialization and authentication checks are performed, and then decide if the user should be routed to the home page as an authenticated user or to the login page for authentication. Tns run ios -bundle Authentication and routingĪpps relying on Firebase for authentication and data will need to initialize the Firebase SDK first and then check to see if the user if already logged in on the current app/device. Start from the basic login app in the previous post. The application will use VueX for local app state and routing, Firebase Firestore as a remote database, and Firebase Storage for profile picture storage. We'll start by adding common app pages, and focus on a functional profile page and login/logout routing.

This post will show how to extend it into a more realistic Nativescript Vue app that uses various Firebase services. In a previous post I described how to create a Nativescript Vue v2 app with a login screen and Firebase for authentication.
