What is the best way to showcase a standalone JSON object within the template?

I have a detailed component that is designed to show the 5-day forecast for a specific city. I have successfully retrieved the data using the http.get(Url) method.

However, I am unsure of how to bind this JSON data to my view.

I am familiar with displaying data in a list view, but I am not sure how to display a single object.

Detailed Component:

@Component({
  selector: 'app-weather-detail',
  templateUrl: './weather-detail.component.html',
  styleUrls: ['./weather-detail.component.css']
})
export class WeatherDetailComponent implements OnInit {

  public weatherDetailItem: any;
  private name: any;

  constructor(
    private weatherService: WeatherService,
    private route: ActivatedRoute,
    private location: Location
  ){}

  //This method will retrieve the 5-day forecast for the city name in the route parameter
  getWeatherItem(){
    this.weatherService.fetchDetail(this.name)
      .do(data => console.log(data))
      .subscribe((data) => {
        this.weatherDetailItem = data;
      })
  }

  goBack(): void {
    this.location.back();
  }

  ngOnInit() {
    this.name = this.route.snapshot.params['name'];
    this.getWeatherItem();
  }


}

fetchDetail() makes the http.get call and fetches this data:

In my template, I have the following:

<div>
   <h3>CITY:</h3>
   <h3>{{weatherDetailItem}}</h3>
</div>

Upon loading the page, it displays City: [object Object]. I attempted to access the JSON data using {{weatherDetailItem.city.name}}, but encountered an error. Any suggestions?

Thank you

Answer №1

You have the option to utilize the ?. operator for asynchronous calls. Therefore, you can extract the city name like this:

{{weatherDetailItem?.city.name}}

Answer №2

this.detailItemWeather = data.city.name

Would you be able to assign the detail at this point? The problem arises due to the asynchronous loading of the data, causing it not to exist during rendering.
