Angular 5 Role Permission or Access Control

ngx-permission

First install npm package and then install npm permission package ngx-permission


   npm i ngx-permissions


or


                                                        npm install ngx-permissions --save


and  then from your angular main module AppModule



mport { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';

// Import your library
import { NgxPermissionsModule } from 'ngx-permissions';

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

    // Specify your library as an import
     NgxPermissionsModule.forRoot()
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }


And your app component sharemodule that import in multiple other feature modules, you can export the ngxpermissionsmodule to make sure you don't have to import in every module.


@NgModule({
    exports: [
        CommonModule,
        NgxPermissionsModule
    ]
})
export class SharedModule { }

and then lazy loaded modules should be add ngxpermission

when you lazy load a module, you should use the for child static method to import the ngxpermissionsmodule.

You can also  isolate the services by using permissionIsolate: true


@NgModule({
    imports: [
        NgxPermissionsModule.forChild()
    ]
})
export class LazyLoadedModule { }


@NgModule({
    imports: [
        NgxPermissionsModule.forChild({
        permissionsIsolate: true, 
        rolesIsolate: true})
    ]
})
export class LazyIsolatedLoadedModule { }

Once your library is imported, you can use its components, directives and pipes in your Angular application: Import service to the main application and load permissions

import { Component, OnInit } from '@angular/core'; import { NgxPermissionsService } from 'ngx-permissions'; import { HttpClient } from '@angular/common/http'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent implements OnInit { title = 'app'; constructor(private permissionsService: NgxPermissionsService, private http: HttpClient) {} ngOnInit(): void { const perm = ["ADMIN", "EDITOR"]; this.permissionsService.loadPermissions(perm); this.http.get('url').subscribe((permissions) => { //const perm = ["ADMIN", "EDITOR"]; example of permissions this.permissionsService.loadPermissions(permissions); }) } }


template view file

<div *ngxPermissionsOnly="['ADMIN', 'GUEST']"> <div>You can see this text congrats</div> </div> <ng-template ngxPermissionsOnly="ADMIN"> <div>You can see this text congrats</div> </ng-template> <ng-template [ngxPermissionsExcept]="['JOHNY']"> <div> All will see it except JOHNY</div> </ng-template>
