// app.module.ts

import { HttpClientModule } from '@angular/common/http';

imports: [
  BrowserModule,
  AtomSpinnerModule,
  HttpClientModule
],

Member.ts.

// Member.ts

export interface Member {
    id: Number;
    name: String;
    salary: Number;
}

Make a service using CMD

ng g s member --spec=false

member.service.ts

// member.service.ts

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})
export class MemberService {

  constructor(private http: HttpClient) { }
  url = 'http://localhost:4000';
  getMembers() {
    return this
            .http
            .get('${this.url}/memberList');
        }

import { Component, OnInit } from '@angular/core';
import { MemberService } from './member.service';
import { Member } from './Member';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  display = false;
  members: Member[];

  constructor(private memberService: MemberService) {}

  ngOnInit() {
    this.memberService
      .getMembers()
      .subscribe((data: Member[]) => {
          this.members = data;
        });

  fetchMembers() {
    this.memberService
      .getMembers()
      .subscribe((data: Member[]) => {
        this.members = data;
