Lazy load modules on same path based on role

I am trying to load an Angular Module based on my role (when I am logged in). I tried it with an Angular Guard but that is not working, when it fails it does not go to the next route.



const routes: Routes = [
{
path: '',
loadChildren: () => AuthModule
// Load when not logged in
},

{
path: '',
loadChildren: () => AdminModule
// Load when admin
},

{
path: '',
loadChildren: () => CrewModule
// Load when crew
}
];


Any ideas for how to fix this? I think an Angular Guard or using a matcher is not the right solution for this...



Edit: For each path/module I have my own guard looking like the following:



import { Injectable } from '@angular/core';
import { CanLoad, CanActivate, Route, Router } from '@angular/router';
import { AuthService } from '@app/core';

@Injectable()
export class AdminModuleGuard implements CanLoad {
constructor(private authService: AuthService, private router: Router) {}

canLoad(route: Route): boolean {
const url: string = route.path;
console.log('Admin Module Load Guard - Url:' + url);
return false;
}
}


Thanks!

  • What exactly did you implement as the logic for your Guard? I think you can specify two different routes for both the modules and then navigate to a particular one based on the role of the user in the guard logic itself.

    Definitely Angular Guard is the solution for this, is exactly what it does: angular.io/guide/router#milestone-5-route-guards

  • @fmontes But when the first guard fails, lets say 'AuthModule' is does not check if the next guard will pas or fail. Am I correct?

  • So in your case is like a it will check if user is login, then if its admin or crew, right? If that's the case, you can create a guard for admin and admin that can use a service that will check first if the user is login and then what role it have, there are several tutorials on this role based guards, but here is one: blogs.msdn.microsoft.com/premier_developer/2018/03/07/…

Well, I was thinking more along the lines of this:



Have different routes defined for different types of user roles:



const routes: Routes = [
{ path: '/login', loadChildren: './auth/auth.module#AuthModule' },
{ path: '/admin', loadChildren: './admin/admin.module#AdminModule' },
{ path: '/crew', loadChildren: './crew/crew.module#CrewModule' }
];


And then in your Guard Logic:



import { Injectable } from '@angular/core';
import { CanLoad, CanActivate, Route, Router } from '@angular/router';
import { AuthService } from './authentication/services/auth.service';

@Injectable()
export class AuthGuardService implements CanLoad {
constructor(
private authService: AuthService,
private router: Router
) {}

canLoad(route: Route): boolean {
let url: string = route.path;
switch(url) {
case '/login': {
if(this.authService.isUserLoggedIn()) {
this.authService.userRole === 'ADMIN' ? this.router.navigate(['/admin']) : this.router.navigate(['/crew']);
return false;
} else {
return true;
}
break;
}
case '/admin': {
if(this.authService.isUserLoggedIn()) {
if(this.authService.userRole === 'ADMIN') {

return true;
