What is the best way to obtain clear HTTP request data in a component?

My service retrieves JSON data from the backend:

constructor(private http: Http) { };
getUsers(): Observable<any> {
    return this.http.get('http://127.0.0.1:8000/app_todo2/users_list');
};

In the component, this data is processed:

ngOnInit() {
    this.retrieveUserData();
}
private retrieveUserData(): void {
    this.userDataService.getUsers().subscribe(
    data => {    
      this.processedUserData = JSON.parse(data.json());                 
      console.log(this.processedUserData);
    })
};  

However, I would like to process this data in the service instead. And then receive the clean data in the component:

private retrieveUserData(): void {
    this.userDataService.getUsers().subscribe(
    data => {    
      this.processedUserData = data;                 
      console.log(this.processedUserData);
    })
};  

Could someone please assist me with this?

Answer №1

Plot your information about services:

    fetchUsersInfo(): Observable<any> {
        return this.http.get('http://127.0.0.1:8000/app_todo2/users_list')
                 .plot(data => data.json());
    }

next:

private retrieveAllUsersData(): void {
    this.usersService.fetchUsersInfo().subscribe(
    data => {    
      this.allUsersData = data;                 
      console.log(this.allUsersData);
    })
};
