GET() communication between Angular and Node JS - node.js

Question

I have an Angular and Node JS project with Typescript in which I am trying to create the communication between them using a service.
When making a get() request from the front I can't get anything from the back, I don't know what I might be missing to configure or what problem I have in the service.
This is the API response:
This is the service.ts:
import { Injectable } from "#angular/core";
import { HttpClient } from "#angular/common/http";
#Injectable({
providedIn: 'root'
})
export class DashboardService {
private url = 'http://localhost:8080/list/product'
constructor(
private http: HttpClient
) {}
public getTest() {
return this.http.get(`${this.url}`);
}
}
This is the component.ts where I am trying to display the message on the console:
import { Component, OnInit } from '#angular/core';
import { DashboardService } from './dashboard.service';
#Component({
selector: 'app-dashboard',
templateUrl: './dashboard.component.html',
styleUrls: ['./dashboard.component.scss']
})
export class DashboardComponent implements OnInit {
constructor(
private dashboardService: DashboardService
) {
}
ngOnInit() {
console.log('hola')
console.log(this.dashboardService.getTest().subscribe())
}
}
This is what I get on the console:
How should I do the GET() request to communicate with the back?

Answer 1

You are subscribing but then doing nothing with the subscription. I recomment you read up on angular subscriptions a bit more, but effectively what you want to do is get the result from the subscription like so.
items: string[];
this.dashboardService.getTest().subscribe({
next: result => items = result,
});
Also your get method in your service needs a bit of work.
public getTest(): Observable<string[]> {
return this.http.get<string[]>(`${this.url}`);
}
This is for returning a list of strings
