Frontegg Angular Set Up

STEP 1: Create Angular app

📘

If you have an existing app, skip this step.

Install Angular command line interface.

npm install -g @angular/cli

To create a new app, use the following script.

ng new my-app
cd my-app
ng serve --open

STEP 2: Install

Run the following command to install the Frontegg Angular library.

npm install @frontegg/angular

STEP 3: Configure

1. Add FronteggAppModule to AppModule.imports[]
2. Add FronteggComponent to AppModule.entryComponents[]

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { CommonModule } from '@angular/common';
import { FronteggAppModule, FronteggComponent } from '@frontegg/angular';

@NgModule({
  declarations: [AppComponent],
  imports: [
    CommonModule,
    BrowserModule,
    AppRoutingModule,

    /** 1. Import Frontegg Module **/
    FronteggAppModule.forRoot(
      {
        contextOptions: {
          baseUrl: 'https://[YOUR-SUB-DOMAIN].frontegg.com',
          clientId: '[YOUR-CLIENT-ID]'
        },
        hostedLoginBox: true,
      }
    ),
  ],

  /** 2. Add Frontetgg Component to your entryComponents **/
  entryComponents: [FronteggComponent],

  bootstrap: [AppComponent],
})
export class AppModule { }

In app.component.ts, add the loading state and loginWithRedirect hook in order to navigate to the hosted login.

import {Component, OnDestroy, OnInit} from '@angular/core';
import {Subscription} from "rxjs";
import {FronteggAppService, FronteggAuthService} from "@frontegg/angular";

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
})
export class AppComponent implements OnInit, OnDestroy {
  isLoading = true;
  loadingSubscription: Subscription;
  user?: any;

  constructor(private fronteggAuthService: FronteggAuthService, private fronteggAppService: FronteggAppService) {
    this.loadingSubscription = fronteggAppService.isLoading$.subscribe((isLoading) => this.isLoading = isLoading)
  }

  ngOnInit(): void {
    this.fronteggAuthService?.user$.subscribe((user) => {
      this.user = user
    })
  }

  loginWithRedirect(): void {
    this.fronteggAuthService.loginWithRedirect();
  }

  ngOnDestroy(): void {
    this.loadingSubscription.unsubscribe()
  }
}

On the hosted login configuration, add http://localhost:4200/oauth/callback as the allowed redirectUrl

🚧

Configure Each Environment

Configure the hosted login for each environment separately.

STEP 4: Redirect to login

In app.component.html, for non-authenticated users, clicking the loginWithRedirect() will navigate the user to the hosted login. Once the user is authenticated, the user info will be available on the user object available from the component.

<div *ngIf="!isLoading">
  <div *ngIf="user">
    <img src={{user?.profilePictureUrl}} alt={{user?.name}} />
    <div>User name: {{user?.name}}</div>
  </div>
  <div *ngIf="!user">
    <button (click)="loginWithRedirect()">Login with redirect</button>
  </div>
</div>

Great, Frontegg is now integrated with your app!
