Permission Management

A permission is a simple policy that is granted or prohibited for a particular user, role or client. You can read more about authorization in ABP document.

You can get permission of authenticated user using getGrantedPolicy selector of ConfigState.

You can get permission as boolean value from store:

import { Store } from '@ngxs/store';
import { ConfigState } from '../states';

export class YourComponent {
  constructor(private store: Store) {}

  ngOnInit(): void {
    const canCreate = this.store.selectSnapshot(ConfigState.getGrantedPolicy('AbpIdentity.Roles.Create'));
  }

  // ...
}

Or you can get it via ConfigStateService:

import { ConfigStateService } from '../services/config-state.service';

export class YourComponent {
  constructor(private configStateService: ConfigStateService) {}

  ngOnInit(): void {
    const canCreate = this.configStateService.getGrantedPolicy('AbpIdentity.Roles.Create');
  }

  // ...
}

Permission Directive

You can use the PermissionDirective to manage visibility of a DOM Element accordingly to user's permission.

<div *abpPermission="AbpIdentity.Roles">
  This content is only visible if the user has 'AbpIdentity.Roles' permission.
</div>

As shown above you can remove elements from DOM with abpPermission structural directive.

The directive can also be used as an attribute directive but we recommend to you to use it as a structural directive.

Permission Guard

You can use PermissionGuard if you want to control authenticated user's permission to access to the route during navigation.

Add requiredPolicy to the routes property in your routing module.

const routes: Routes = [
  {
    path: 'path',
    component: YourComponent,
    canActivate: [PermissionGuard],
    data: {
      routes: {
        requiredPolicy: 'AbpIdentity.Roles.Create',
      },
    },
  },
];

Granted Policies are stored in the auth property of ConfigState.
