Configuration

Override or change options property of BaseAuthService

Option name	Default value	Description
afterSignInPage	"/"	Path where user will be redirected after successful sign in. If false, no redirect will be done.
providers	{}	List of provider configurations. See example configuration.
redirectBack	true	When true, user will be redirected back to requested router path after sign in
signInPage	"/sign-in"	Path where user will be redirected when sign in is required (and after logout). If false, no redirect will be done.
storage	false	You can store user profile data in Firestore ('firestore') or nowhere (false).
storageUserTable	"users"	If you specify storage, than this table name / key will be used.
mapUserToStorageFunc		You can use custom strategy to map user model to storage. See example configuration.
storageUserFactoryFunc		You can use custom model object for user in storage. See example configuration.
userFactoryFunc		You can use custom model object for user. See example configuration.

Example configuration

import { NgModule } from "@angular/core";
import { AngularFireModule } from "@angular/fire";
import { AngularFirestoreModule } from "@angular/fire/firestore";
import { FacebookAuthModule, GoogleAuthModule, UniFirebaseLoginModule } from "ionic-universal-firebase-login";
import { environment } from "../environments/environment";
import { Player } from "./model/player.model";
import * as firebase from "firebase";

export function mapFirebaseUserToStorageFunc(user: firebase.User) {
    return {
        uid: user.uid,
        email: user.email,
        displayName: user.displayName,
        photoURL: user.photoURL,
    };
}

export function userFactoryFunc(): Player {
    return new Player();
}

@NgModule({
    imports: [
        ...
        AngularFireModule.initializeApp(environment.firebase),
        AngularFirestoreModule,
        UniFirebaseLoginModule.forRoot({
            storage: "firestore",
            storageUserTable: "players",
            signInPage: "login",
            userFactoryFunc,
            mapFirebaseUserToStorageFunc
        }),
        GoogleAuthModule,
        FacebookAuthModule,
    ],
    ...
})
export class AppModule {
}

Usage in template:

import { Component, OnInit } from "@angular/core";
import { BaseAuthService } from "ionic-universal-firebase-login";

@Component({
  selector: "app-sample",
  template: `
    Username: {{ auth.user?.displayName }}
    Email: {{ auth.user?.email }}
  `,
})
export class SamplePage {
  constructor(
    public auth: BaseAuthService,
  ) {}
}

Installation

Before you start, be sure that you have signed your application. It is required for native authentication on Android and iOS.

Install with npm:

npm install firebase @angular/fire ionic-universal-firebase-login

Go to https://firebase.google.com/ → create a new Firebase project (if you don't have it already).
- Project overview → Create Web app
- Firebase settings → General tab → Web app project (at the bottom) → Config → copy Firebase SDK snippet (Configuration is the same for all platforms, so you have to do this step only once.)
Edit src/environments/environment.ts and paste the config from previous step as in example below:

export const environment = {
    ...
    firebase: {
        apiKey: "XXX",
        authDomain: "XXX.firebaseapp.com",
        databaseURL: "https://XXX.firebaseio.com",
        projectId: "XXX",
        storageBucket: "XXX.appspot.com",
        messagingSenderId: "XXX",
        appId: "XXX",
        measurementId: "G-XXX",
    },
}

Edit src/app/app.module.ts and add:

import { NgModule } from '@angular/core'; 
import {AngularFireModule} from '@angular/fire';
import {environment} from '../environments/environment';
import {UniFirebaseLoginModule, GoogleAuthModule, FacebookAuthModule} from 'ionic-universal-firebase-login';

@NgModule({
    ...
    imports: [
        ...
        AngularFireModule.initializeApp(environment.firebase),
        UniFirebaseLoginModule.forRoot(),
        GoogleAuthModule, // if you want to use Google as a provider
        FacebookAuthModule, // if you want to use Facebook as a provider
    ]
})

App for Android platform:

Create Android app in Firebase similarly as Web app
Android package name have to be same as you have in config.xml (<widget id="..."). If you have some default package id in config.xml, edit it.
If you don't have SHA-1 key, see guide for Android:
- Create your keystore with a key: https://coderwall.com/p/r09hoq/android-generate-release-debug-keystores
- Get SHA-1 from your keystore: https://developers.google.com/android/guides/client-auth
Enter SHA1 key in the first step of Android app creation.
Click to Download google-services.json and copy it to your project root
Skip last (4th) step, because its for Android Studio project only.

See our guide for each provider:

Google - see guide
Facebook - see guide
Use AuthGuard in your router like this:

import { NgModule } from "@angular/core";
import { PreloadAllModules, RouterModule, Routes } from "@angular/router";
import { AuthGuard } from "ionic-universal-firebase-login";

const routes: Routes = [
  {
    path: "",
    loadChildren: () =>
      import("./home.module").then(m => m.HomePageModule),
    canActivate: [AuthGuard],
    canActivateChild: [AuthGuard],
  },
  {
    path: "sign-in",
    loadChildren: () => import("./sign-in/sign-in.module").then(m => m.SignInPageModule),
  },
];

@NgModule({
  imports: [
    RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules }),
  ],
  exports: [RouterModule],
})
export class AppRoutingModule {
}
