Installation

npm i ng-remote-validations

Setup

Simply import NgRemoteValidationsModule from the library to your app.module.ts and specify the global configurations as shown in the example below.

import { NgRemoteValidationsModule } from 'ng-remote-validations';


@NgModule({
  imports: [
    // ....
    NgRemoteValidationsModule,
  ],
  providers: []
})
export class AppModule {
}

Usage

Use with angular reactive forms

<form [formGroup]='form'>
    <mat-form-field>
      <mat-label>Name</mat-label>
      <ng-file-input required formControlName='name'></ng-file-input>
      <mat-error validate='name'></mat-error>
    </mat-form-field>
  </form>

Import the remote validation service to wherever you might want to obtain the errors. The interceptor is a sound option for the purpose and follows an example on how you may use this with an interceptor.

@Injectable()
export class HttpInterceptorInterceptor implements HttpInterceptor {

  constructor(
    //   ...
    private remoteValidationService: NgRemoteValidationsService,
  ) {}

    //   ....
  intercept(request: HttpRequest<unknown>, next: HttpHandler): Observable<HttpEvent<unknown>> {

			// ...
			return next.handle(request) 
    .pipe(
      tap(
							(resp: any) => {},
							(err: any) => {
								// Populate the errors
								if( err.status == 422  || err.status == 406 ) {
											if(err.error.errors) {
													this.serverValidations.refresh(err.error.errors);
											}
								}
							},
						)
				);
		}
}
