I am embarking on a new angular project and my application involves three different types of users - admin, customer, and company. I am facing an issue with restricting customers from accessing the admin user menus. How can this limitation be implemented in my project?
If you're looking to implement role-based permissions in your Angular project, consider using the ngx-permissions library. It offers support for lazy loading, isolated lazy loading, and provides a convenient 'then else' syntax for handling permissions.
@NgModule({
imports: [
NgxPermissionsModule.forRoot()
],
providers: [],
bootstrap: [AppComponent]
})
To load roles, simply add them using the following code:
this.ngxRolesService.addRole('GUEST', () => {
return true;
});
To secure the root of your application, define routes with permissions as shown below:
const appRoutes: Routes = [
{ path: 'home',
component: HomeComponent,
canActivate: [NgxPermissionsGuard],
data: {
permissions: {
only: 'GUEST'
}
}
},
];

To control access to a particular URL or resource, it is recommended that you utilize the ActivatedRoute interface in your application. For further details on how to implement this, you can refer to the official documentation here
Managing menu voices in a database is crucial for maintaining secure server controls and handling user permissions effectively. By setting up different levels of access, users can be granted or denied certain actions based on their privileges.
{ path: 'profile/:user_level', component: ProfileComponent }
To customize the user experience on the client side, you can easily adjust your routing module by adding a variable:
this.user_level= + params['user_level'];
this.utilityService.checkUserLevel(this.user_level);
In order to restrict users from accessing content that does not match their level, it's important to implement a control mechanism. This can be achieved by verifying the session user against the required permission level, as demonstrated in the example within the ProfileComponent.
checkUserLevel(url_liv_serial: number) {
let currentUser: User = JSON.parse(localStorage.getItem('currentUser'));
if (url_liv_serial < utente.ute_liv_serial) {
this.router.navigate(['/login']);
let snackBarRef = this.snackBar.open('Access denied', 'Close', {
duration: Constants.short_time_sb
});
}
}
Ensure the security of your routes by limiting access to specific menu items and preventing unauthorized users from viewing them.
Utilize database-driven permissions to protect routes with guards in Angular 2, while also using the ng-if directive to restrict the rendering of certain menu items.
