Add Angular Material (skip if you already installed it):

ng add @angular/material

Add Angular Material Theme And FontAwesome (scss)

@import '~@angular/material/theming';
@import '~@fortawesome/fontawesome-free/css/all.css';

Adding Custom Material Theme

@import '~ngx-crud-manager/styles/theme;
@include mat-core();
$ngx-primary: mat-palette($mat-blue-grey);
$ngx-accent:  mat-palette($mat-cyan, 500, 200, 900);
$ngx-warn:    mat-palette($mat-red);
$ngx-theme: mat-light-theme($ngx-primary, $ngx-accent, $ngx-warn);
@include ngx-crud-color($ngx-theme);

Setup

Just import the module to your app.module.ts

imports: [
  ...
  NgxCrudModule
]

Creating your first CRUD Service

In order to make our interface work with your api, you need to declare a service with the ICRUDService Methods.

The library also has a SetupParams function in order to make things easier for you.

Make sure you have HttpClientModule and RouterModule.forRoot() imported.

item.service.ts

@Injectable({
  providedIn: 'root'
})
export class ItemService implements ICRUDService {
  apiUrl = 'http://localhost:3000/api';
  constructor(private http: HttpClient) {

  }
  index(value = null, page = 1){
    return this.http.get(this.apiUrl + '/items', SetupParams({search: value, page}));
  }
  create(value) {
    return this.http.post(this.apiUrl + '/items', {
      item: value
    }, SetupParams());
  }
  update(id, value) {
    return this.http.put(this.apiUrl + '/items', {
      item: value
    }, SetupParams());
  }
  destroy(id) {
    return this.http.delete(this.apiUrl + '/items/' + id, SetupParams());
  }
  restore(id) {
    return this.http.delete(this.apiUrl + '/items/' + id + '/restore', SetupParams());
  }
}

Adding the interface to a component

app.component.html

<ngx-crud-manager [service]="itemService"></ngx-crud-manager>

app.component.ts

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  constructor(public itemService: ItemService){

  }
}

Adding a custom form

Using ReactiveForms we create a new Form with our required fields

app.component.ts

export class AppComponent {
  formGroup = new FormGroup({
      name: new FormControl('', Validators.required)
    });
  constructor(
    public itemService: ItemService,
    private fb: FormBuilder,
  ) {

  }
}

Then we add our form template to the component and setup our crud manager formTemplate and formGroup values

app.component.html

<ngx-crud-manager [service]="itemService" [formTemplate]="formTemplate" [formGroup]="formGroup"></ngx-crud-manager>

<ng-template #formTemplate let-form="form">
  <form [formGroup]="form">
    <mat-form-field>
      <input matInput type="text" placeholder="Item Name" required formControlName="name" name="name">
    </mat-form-field>
  </form>
</ng-template>

Setting a custom list item display

We create a item template and setup it in the crud manager

<ng-template #itemTemplate let-item>
  <span>{{item.id}} - {{item.name}}</span>
</ng-template>
<ngx-crud-manager [service]="itemService" [itemTemplate]="itemTemplate"></ngx-crud-manager>

Nested Routes

If you have routes like /collection/:id/items you can add arguments to the manager

app.component.html

<ngx-crud-manager [service]="itemService" [formTemplate]="formTemplate" [formGroup]="formGroup" [args]=[collection.id]></ngx-crud-manager>

CRUD Manager with call your service with aditional arguments

item.service.ts

create(value,collection_id) {
    return this.http.post(this.apiUrl + 'collection/'+collection_id+'/items', {
      item: value
    }, SetupParams());
  }

You can use this to add custom params

app.component.html

<ngx-crud-manager [service]="itemService" [formTemplate]="formTemplate" [formGroup]="formGroup" [args]=[collection.id,{token: token}]></ngx-crud-manager>

item.service.ts

create(value,collection_id,params) {
    return this.http.post(this.apiUrl + 'collection/'+collection_id+'/items', {
      item: value
    }, SetupParams(params));
  }

Using a dynamic service

Setup as argument the Restful api endpoint and provide to you service.

app.component.html

<ngx-crud-manager [service]="itemService" [formTemplate]="formTemplate" [formGroup]="formGroup" [args]=[endpoint]></ngx-crud-manager>

dynamic.service.ts

@Injectable({
  providedIn: 'root'
})
export class DynamicService implements ICRUDService {
  apiUrl = 'http://localhost:3000/api';
  constructor(private http: HttpClient) {

  }
  index(value = null, page = 1, endpoint) {
    return this.http.get(this.apiUrl + `/${endpoint}`, SetupParams({search: value, page}));
  }
  create(value, endpoint) {
    return this.http.post(this.apiUrl + `/${endpoint}`, {
      item: value
    }, SetupParams());
  }
  update(id, value, endpoint) {
    return this.http.put(this.apiUrl + `/${endpoint}`, {
      item: value
    }, SetupParams());
  }
  destroy(id, endpoint) {
    return this.http.delete(this.apiUrl + `/${endpoint}/` + id, SetupParams());
  }
  restore(id, endpoint) {
    return this.http.delete(this.apiUrl + `/${endpoint}/` + id + '/restore', SetupParams());
  }
}

Backend required responses

You can use any Url and request format since you can configure it in your service, the only real requirement is your backend response

URL SERVICE METHOD REQUEST RESPONSE CODE
GET /items index {page: number, search: string} items[{id:number}] 200
POST /items create {item: any} {id: number, ...item} 200-201
PUT /items/:id update {id: number, item: any} {id: number, ...item} 200
DELETE /items/:id destroy {id: number} any 200
PATCH /items/:id/restore restore {id: number} any 200
POST /items/:id/clone clone {id: number} {id: number, ...item} 200
POST /items/swap swap {ordered_ids: number[]} any 200
