Side Menu, Tabs and Authentication Flow in Ionic

Aaron K Saunders - Dec 29 '19 - - Dev Community

Building a Basic Ionic 4 Login Flow with Angular Router & Side Menu UI
( now with Tabs !! )

Updated to latest Ionic Versions 

Ionic:

   Ionic CLI                     : 5.4.13 (/Users/aaronksaunders/.nvm/versions/node/v10.15.1/lib/node_modules/ionic)
   Ionic Framework               : @ionic/angular 4.11.7
   @angular-devkit/build-angular : 0.803.21
   @angular-devkit/schematics    : 8.1.3
   @angular/cli                  : 8.1.3
   @ionic/angular-toolkit        : 2.1.1

Utility:

   cordova-res                          : not installed
   native-run (update available: 0.3.0) : 0.2.9

System:

   NodeJS : v10.15.1 (/Users/aaronksaunders/.nvm/versions/node/v10.15.1/bin/node)
   npm    : 6.11.2
   OS     : macOS Catalina
Enter fullscreen mode Exit fullscreen mode

How It Works

We put an AuthGuard on the module that provides access to all of the member related pages and functionality. The login page has no gaurd so it can be freely accessed. See more information on Route Guards in the angular.io documentation

const routes: Routes = [
  { path: '', redirectTo: 'login', pathMatch: 'full' },
  { 
    path: 'members', 
    canActivate: [AuthGuardService],
    loadChildren: './members/member-routing.module#MemberRoutingModule'
  },
  { path: 'login', loadChildren: './public/login/login.module#LoginPageModule' }
];
Enter fullscreen mode Exit fullscreen mode

The member routing module is where we control access to the private content. An import note from the documentation is what supports this approach.

The Routing Module is a design choice whose value is most obvious when the configuration is complex and includes specialized guard and resolver services. It can seem like overkill when the actual configuration is dead simple.
See more information on Routing Modules in the Angular.io Documentation

We created the authentication.service to track in the user is logged in or out and to manage the two different states.

// file: authentication.service.ts
export class AuthenticationService {
  isLoggedIn = false;

  constructor() {}

  setLoggedIn(_value) {
    this.isLoggedIn = _value;
  }
  isAuthenticated(): boolean {
    return this.isLoggedIn;
  }
}
Enter fullscreen mode Exit fullscreen mode

This service is injected into the AuthGuard to help control access to a specific route.

  // file: authGuard.service.ts
  canActivate(): boolean {
    let value = this.auth.isAuthenticated() // <= from auth service
    if (!value) {
      this.router.navigateByUrl("/login")
    }
    return value
  }
}
Enter fullscreen mode Exit fullscreen mode

and it is also used in the user interface, app.component.html to control the visibility of the side-menu. Meaning if you are not authenticated than the side menu isnt going to be showing.

<!-- file: app.component.html -->
<ion-app>
  <ion-split-pane>
    <ion-menu *ngIf="auth.isAuthenticated() === true"> // CHECK TO SEE IF THIS SHOULD BE DISPLAYE
      <ion-header>
        <ion-toolbar>
          <ion-title>Menu</ion-title>
        </ion-toolbar>
      </ion-header>
      <ion-content>
      // MENU CONTENT
      </ion-content>
    </ion-menu>
    <ion-router-outlet main></ion-router-outlet>
  </ion-split-pane>
</ion-app>
Enter fullscreen mode Exit fullscreen mode
