Property 'subscribe' does not exist on type '() => Observable'

Question

service file

import { Observable } from \'rxjs/Rx\';
import { Http,Response} from \'@angular/http\';
import { Injectable } from \'@angular/core\';
import \'         


        

Answer 1

ngOnInit() {
    this.videoserv.getvideos().subscribe((response) => {
         this.videos = response
    });
}

You should be calling the getvideos() method on the videoserv service. You were missing the (), getvideos is a method not a property.

Answer 2

You are not calling the getVideos method. You are calling subscribe on the function reference of getVideos and not the returned value. Call subscribe after you call getVideos():

ngOnInit() {
    this.videoserv.getvideos().subscribe((response) => {
         this.videos = response
    });
}
