@NgModule({

  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Inject the service

  constructor(private objectDiff: NgxObjectDiffService) { }

  ngOnInit(): void {
    // This is required only if you want to show a JSON formatted view of your object
    this.object1View = this.objectDiff.objToJsonView(this.object1);
    this.object2View = this.objectDiff.objToJsonView(this.object2);
    
    // you can directly diff your objects js now or parse a Json to object and diff
    let diff = this.objectDiff.diff(this.object1, this.object2);
    // you can directly diff your objects including prototype properties and inherited properties using `diff` method
    let diffAll = ObjectDiff.diff($scope.yourObjectOne, $scope.yourObjectTwo);    

    // gives a full object view with Diff highlighted
    this.diffView = this.objectDiff.toJsonView(diff)
    // gives object view with only Diff highlighted
    this.diffValueChanges = ObjectDiff.toJsonDiffView(diff);
  }

Component

Bind the variables to ngx-object-diff Component.It will takes care of styling.

   <ngx-object-diff [obj]="object1View"></ngx-object-diff>
   <ngx-object-diff [obj]="object1View"></ngx-object-diff>
   <ngx-object-diff [obj]="diffView"></ngx-object-diff>
   <ngx-object-diff [obj]="diffValueChanges"></ngx-object-diff>

Alternate approach

Bind the variables directly in your html using the innerHTML property binding of Angular Use a <pre> element for better results

      <pre [innerHTML]="object1View" ></pre>
      <pre [innerHTML]="object2View" ></pre>
      <pre [innerHTML]="diffView" ></pre>
      <pre [innerHTML]="diffValueChanges"></pre>
