Предыдущая статья: Создание пустого проекта с помощью NestJS-mod

Создание приложения происходит через nx схематик для Angular.

Адрес сервера задается жестко в коде, в следующих постах адрес будет перенесен в переменные окружения.

Для запуска E2E-тестов используется "Playwright".

Устанавливаем необходимые библиотеки и создаем пустое Angular приложение

apps/client/src/test-setup.ts:1:1 - error TS2578: Unused '@ts-expect-error' directive.

1 // @ts-expect-error https://thymikee.github.io/jest-preset-angular/docs/getting-started/test-environment
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Found 1 error in apps/client/src/test-setup.ts:1

Получаем ошибку "Unused '@ts-expect-error' directive." и решаем ее

Так как nx содержит множество различных шаблонов под разные фреймворки, часто можно встретить неявные ошибки которые не понятно как устранять, для обхода текущей ошибки просто просто перебьем типизацию и удалим директиву.

Обновленный файл apps/client/src/test-setup.ts

    errorOnUnknownElements: true,
    errorOnUnknownProperties: true,

Добавляем работу с хттп в Angular приложении

Обновленный конфиг apps/client/src/app/app.config.ts

import { ApplicationConfig, provideZoneChangeDetection } from '@angular/core';
import { provideRouter } from '@angular/router';
import { appRoutes } from './app.routes';
import { provideClientHydration } from '@angular/platform-browser';
import { provideHttpClient } from '@angular/common/http'; // <---

  providers: [
    provideClientHydration(),
    provideZoneChangeDetection({ eventCoalescing: true }),
    provideRouter(appRoutes),
    provideHttpClient(), // <---
  ],
};

import { Component, OnInit, ViewEncapsulation } from '@angular/core';
import { RouterModule } from '@angular/router';
import { NxWelcomeComponent } from './nx-welcome.component';
import { HttpClient } from '@angular/common/http';

@Component({

  imports: [NxWelcomeComponent, RouterModule],

  encapsulation: ViewEncapsulation.None,

  serverMessage!: string;

  constructor(private readonly httpClient: HttpClient) {}

  ngOnInit() {
    this.httpClient.get<{ message: string }>('http://localhost:3000/api').subscribe((result) => (this.serverMessage = result.message));
  }
}

Добавляем отображение получение данных с сервера

Обновленный корневой html-файл apps/client/src/app/app.component.html

<app-nx-welcome></app-nx-welcome> <router-outlet></router-outlet>
<div id="serverMessage">{{ serverMessage }}</div>

Обновляем E2E-тест в котором проверяем получение и отображение данных с сервера

Обновленный файл с тестом apps/client-e2e/src/example.spec.ts

import { test, expect } from '@playwright/test';

test('has title', async ({ page }) => {
  await page.goto('/');

  // Expect h1 to contain a substring.
  expect(await page.locator('h1').innerText()).toContain('Welcome');
});

test('has serverMessage', async ({ page }) => {
  await page.goto('/');

  // Expect h1 to contain a substring.
  expect(await page.locator('#serverMessage').innerText()).toContain('Hello API');

В посте нет картинок, работа приложений проверяется через тесты, но если кому то нужно видеть результат, то ответ сервера можно получить по адресу: http://localhost:3000/api, а ответ клиента по адресу: http://localhost:4200/

В следующем посте я добавлю докер образ с базой данных Postgres и написание и запуск миграций через Flyway...
