Error in Angular: Property does not exist on specified type

I am facing an issue with my small weather app. While everything works fine in the browser, I am encountering errors from the TS compiler stating that the properties name, main, and wind do not exist on type Weather[]. However, it appears that I have already added these properties in the Weather[] class...

export class AppComponent implements OnInit {  
  // rest of the code remains the same
export class Weather {
    // rest of the code remains the same
}
  //Get Weather 
  //it worked when I changed here Weather[] to Weather !!!
  getWeather(city:string):Observable<Weather> {
    // rest of the code remains the same
  }

Answer №1

After updating Weather[] to simply Weather, the TypeScript compiler no longer threw errors!

Answer №2

Consider setting up data:any within the subscribe block

ngOnInit() {    

    this.getWeatherService.getWeather("Misto Kyyiv").subscribe((data: any)=> {
      this.weather = data;
      this.temp = (data.main.temp -273.15).toFixed(2);
      this.pressure = data.main.pressure;
      this.humidity = data.main.humidity;
      this.wind_speed = data.wind.speed;
      this.wind_dec = data.wind.deg;
      this.city = data.name;
      console.log(this.weather);
      console.log(this.temp);
    });
  }

Answer №3

Encountering the same issue led me to a simple solution that worked wonders.

async fetchProfessional(){
     await this._ps.getProfessional(idProfessional).subscribe( (data:any) => {
        this.professionalSkills = data[0].aptitudes;
        this.technicalSkills = data[0].technologies;
    });
  }

This adjustment did the trick:

async fetchProfessional(){
     await this._ps.getProfessional(idProfessional).subscribe( (data:any) => {
        this.professionalSkills = data[0].aptitudes;
        this.technicalSkills = data[0].technologies;
    });
  }
