When attempting to retrieve information from the API, an error occurred stating that property 'subscribe' is not found in type 'void'

I've attempted to use this code for fetching data from an API.

Below is the content of my product.service.ts file:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { map, Observable } from 'rxjs';
import { Product } from '../common/product';
import 'rxjs/add/operator/map';

@Injectable({
  providedIn: 'root'
})
export class ProductService {
  
 public baseURL ='http://localhost:8080/getBooks'

  constructor(private http:HttpClient) { }

  users(){
    return this.http.get(this.baseURL);
  }
 
}

This is how my homecompoent.ts looks like:

export class HomeComponent {
  public sort: string;
  public books: any ;
  constructor(private bookData:ProductService) 
  { 
    this.bookData.books().subscribe((data) => {
      this.books = data;
  });
  }

Please help me figure out why I'm encountering this subscribe error.

Answer №1

The method you implemented for book() does not output an Observable as expected, instead it returns a void type.
