NgxFirebaseAuth

Components for email-first sign in and out-of-band (oob) actions (reset password, etc). Designed for Angular single page apps with routing.

Example app implementation code

Why?

The current "drop-in" Firebase auth library did not meet the needs of several Angular projects. Your results may vary.

Features:

• All configuration happens via component inputs.
• Explicit sign in success output, passing an instance of auth.UserCredential.
• Sign out link.
• An Oob Component designed to live on a separate route.

Notes

• This is a work in progress.
• The component styling is based on Bootstrap.
• Does not currently support email link and phone sign-in. Supports sign in by password + Google, Facebook, Twitter and GitHub.
• Depends upon angularfire2

Install

npm i @nowzoo/ngx-firebase-auth --save

Component API

Sign In Component

• selector: ngx-firebase-auth-sign-in
• Inputs
  • oAuthProviderIds: string[] Optional. The ids of OAuth providers you want to enable.
  • oAuthProviderFactory: (providerId: string) => auth.AuthProvider Optional. Pass your function for creating providers. If no function is provided here, or the function does not return a provider for a particular provider id, the component will create a default provider.
  • useOAuthPopup: boolean Optional. Default: false. Whether or not to use a popup rather than a redirect for OAuth sign in. See the example app, which uses ngx-device-detector to choose which method to use.
  • tosTemplate: TemplateRef<any> Optional. The HTML in this template is appended to the component.
• Outputs
  • success: EventEmitter<auth.UserCredential>
  • mode: EventEmitter<'signIn' | 'resetPassword'> Use this to set the route title.

Sign In Component Notes

• Only the OAuth providers you pass in oAuthProviderIds will be shown as sign up options for new users.
• For existing users, all oAuth providers for that user will be displayed as sign in options.
• Only the password and the Twitter, Google, GitHub and Facebook providers are currently supported.
• Create a sign out link: <a routerLink="path/to/your/route" [queryParams]="{action: 'signOut'}">Sign Out</a>

Sign In Component Usage

Import NgxFirebaseAuthSignInModule into the module which contains your sign in route...

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { NgxFirebaseAuthSignInModule } from '@nowzoo/ngx-firebase-auth';

import { RouteComponent } from './route/route.component';

const routes: Routes = [
  {path: '', component: RouteComponent}
];
@NgModule({
  imports: [
    CommonModule,
    RouterModule.forChild(routes),
    NgxFirebaseAuthSignInModule
  ],
  declarations: [RouteComponent]
})
export class SignInModule { }

Stick an instance of the sign in component into the HTML of your component...

<!-- route.component.html -->
<ng-template #tos>
  By signing in or signing up for example.com, you agree to our
  <a href="/tos">Terms of Service</a> and
  <a href="/privacy">Privacy Policy</a>.
</ng-template>

<div class="row">
  <div class="col-sm-8 offset-md-2 col-md-6 offset-md-3 col-lg-4 offset-lg-4">
    <h1>{{routeTitle}}</h1>
    <hr>
    <ngx-firebase-auth-sign-in
      [oAuthProviderIds]="['google.com']"
      [tosTemplate]="tos"
      [useOAuthPopup]="deviceDetector.isDesktop()"
      (success)="onSuccess($event)"
      (mode)="onMode($event)">
    </ngx-firebase-auth-sign-in>
  </div>
</div>

...and handle the outputs in your component code...

import { Component } from '@angular/core';
import { DeviceDetectorService } from 'ngx-device-detector';
import { Router } from '@angular/router';
import { auth } from 'firebase/app';
@Component({
  selector: 'app-route',
  templateUrl: './route.component.html',
  styleUrls: ['./route.component.css']
})
export class RouteComponent {

  routeTitle: string = null;
  constructor(
    public deviceDetector: DeviceDetectorService,
    private router: Router
  ) { }


  onMode(mode: 'resetPassword' | 'verifyEmail' | 'recoverEmail') {
    switch (mode) {
      case 'resetPassword':
        this.routeTitle = 'Reset Password';
        break;
      default:
        this.routeTitle = 'Sign In';
        break;
    }
  }

  onSuccess(cred: auth.UserCredential) {
    console.log(cred);
    console.log(`Welcome, ${cred.user.displayName}!`);
    console.log(`You signed in with ${cred.additionalUserInfo.providerId}.`);
    if (cred.additionalUserInfo.isNewUser) {
      console.log(`You are a newly registered user!`);
    } else {
      console.log(`You are a returning user!`);
    }
    this.router.navigate(['/']);
  }

}

Oob Component

• selector: ngx-firebase-auth-oob
• Inputs (none)
• Outputs
  • success: EventEmitter<INgxFirebaseAuthOobSuccess> See below.
  • navigationError: EventEmitter<void> Emitted when one or more of the oob parameters (oobCode and mode) is messing from the querystring. You should handle this by redirecting the user in some way.
  • mode: EventEmitter<'resetPassword' | 'verifyEmail' | 'recoverEmail'> Use this to set the window or route title.

Interface INgxFirebaseAuthOobSuccess

• mode: 'resetPassword' | 'verifyEmail' | 'recoverEmail';
• info: auth.ActionCodeInfo
• cred?: auth.UserCredential Only populated on reset password, when we sign the user in after saving the password.
• user?: User Populated if the user is signed in.

Oob Component Notes

• Only the resetPassword, verifyEmail and recoverEmail oob modes are supported.

Oob Component Usage

Import NgxFirebaseAuthOobModule into the module which contains your sign in route...

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { NgxFirebaseAuthOobModule } from '@nowzoo/ngx-firebase-auth';
import { RouteComponent } from './route/route.component';

const routes: Routes = [
  {path: '', component: RouteComponent}
];

@NgModule({
  imports: [
    CommonModule,
    RouterModule.forChild(routes),
    NgxFirebaseAuthOobModule
  ],
  declarations: [RouteComponent]
})
export class OobModule { }

Stick an instance of the oob component into the HTML of your component...

<!-- route.component.html -->
<div class="row">
  <div class="col-sm-8 offset-md-2 col-md-6 offset-md-3 col-lg-4 offset-lg-4">
    <h1>
      {{routeTitle}}
    </h1>
    <hr>
    <ngx-firebase-auth-oob
      (mode)="onMode($event)"
      (navigationError)="onNavigationError()"
      (success)="onSuccess($event)">
    </ngx-firebase-auth-oob>
  </div>
</div>

... and handle the outputs in your code...

import { Component } from '@angular/core';
import { Router } from '@angular/router';
import { INgxFirebaseAuthOobSuccess } from '@nowzoo/ngx-firebase-auth';
@Component({
  selector: 'app-route',
  templateUrl: './route.component.html',
  styleUrls: ['./route.component.css']
})
export class RouteComponent {

  routeTitle: string = null;
  constructor(
    private router: Router
  ) { }


  onMode(mode: 'resetPassword' | 'verifyEmail' | 'recoverEmail') {
    switch (mode) {
      case 'resetPassword':
        this.routeTitle = 'Reset Password';
        break;
      case 'recoverEmail':
        this.routeTitle = 'Recover Email';
        break;
      case 'verifyEmail':
        this.routeTitle = 'Verify Email';
        break;
    }
  }

  onNavigationError() {
    this.router.navigate(['/']);
  }

  onSuccess(success: INgxFirebaseAuthOobSuccess) {
    switch (success.mode) {
      case 'resetPassword':
        // the user has saved her new password and is signed in...
        console.log(`Welcome, ${success.user.displayName}!`);
        this.router.navigate(['/']);
        break;
      default:
        // etc...
        break;
    }
  }

}
