Предыдущая статья: Добавление базы данных Postgres в проект и запуск миграций через Flyway для NestJS-mod приложения

Подключение Prisma к NestJS происходит через пакет https://www.npmjs.com/package/@nestjs-mod/prisma.

Проверка работы происходит через запуск E2E тесты на REST-ендпойтны.

1. Устанавливаем все необходимые пакеты

Команды

# Install all need dependencies
npm i --save @prisma/client @nestjs-mod/prisma

# Install all need dev-dependencies
npm i --save-dev prisma

Вывод консоли

$ npm i --save @prisma/client @nestjs-mod/prisma

To address issues that do not require attention, run:
  npm audit fix

To address all issues (including breaking changes), run:
  npm audit fix --force

Nx read the output from the cache instead of running the command for 2 out of 3 tasks.

6. Открываем созданный и убеждаемся что PrismaORM-схема полностью повторяет схему базы данных приложения

Обновленный файл apps/server/src/prisma/app-schema.prisma

generator client {
  provider   = "prisma-client-js"
  output     = "../../../../node_modules/@prisma/app-client"
  engineType = "binary"
}

datasource db {
  provider = "postgres"
  url      = env("SERVER_APP_DATABASE_URL")
}

model AppDemo {
  id        String   @id(map: "PK_APP_DEMO") @default(dbgenerated("uuid_generate_v4()")) @db.Uuid

7. Так как по умолчанию pm2 конфигурация содержит запуск уже собранного приложения на NestJS, меняем команду для запуска приложения в режиме watch

Обновленный файл ecosystem.config.json

{
  "apps": [
    {
      "name": "server",
      "script": "./node_modules/.bin/nx serve server",
      "node_args": "-r dotenv/config"
    },
    {
      "name": "client",
      "script": "./node_modules/.bin/nx serve client --host=0.0.0.0 --disable-host-check",
      "node_args": "-r dotenv/config"
    }
  ]
}

8. Перезапускаем все приложения

Команды

# Stop all applications
npm run pm2:stop

# Start all applications
npm run pm2:start

Вывод консоли

$ npm run pm2:stop

9. Добавляем в AppModule модуль для работы с призмой

Обновленный файл apps/server/src/app/app.module.ts

import { createNestModule, NestModuleCategory } from '@nestjs-mod/common';

import { AppController } from './app.controller';
import { AppService } from './app.service';
import { PrismaModule } from '@nestjs-mod/prisma';

export const { AppModule } = createNestModule({
  moduleName: 'AppModule',
  moduleCategory: NestModuleCategory.feature,
  imports: [PrismaModule.forFeature({ featureModuleName: 'app' })],
  controllers: [AppController],
  providers: [AppService],
});

10. Добавляем в AppController дополнительные методы для работы с данными таблички AppDemo

Обновленный файл apps/server/src/app/app.controller.ts

import { Controller, Delete, Get, Param, Post } from '@nestjs/common';

import { InjectPrismaClient } from '@nestjs-mod/prisma';
import { PrismaClient as AppPrismaClient } from '@prisma/app-client';
import { randomUUID } from 'crypto';
import { AppService } from './app.service';
@Controller()
export class AppController {
  constructor(
    @InjectPrismaClient()
    private readonly appPrismaClient: AppPrismaClient,
    private readonly appService: AppService
  ) {}

  @Get()
  getData() {
    return this.appService.getData();
  }

  @Post('/demo')
  async demoCreateOne() {
    return await this.appPrismaClient.appDemo.create({ data: { name: 'demo name' + randomUUID() } });
  }

  @Get('/demo/:id')
  async demoFindOne(@Param('id') id: string) {
    return await this.appPrismaClient.appDemo.findFirstOrThrow({ where: { id } });
  }

  @Delete('/demo/:id')
  async demoDeleteOne(@Param('id') id: string) {
    return await this.appPrismaClient.appDemo.delete({ where: { id } });
  }

  @Get('/demo')
  async demoFindMany() {
    return await this.appPrismaClient.appDemo.findMany();
  }
}

11. Добавляем проверку новых методов в E2E-тесте

Обновленный файл apps/server-e2e/src/server/server.spec.ts

import axios from 'axios';

describe('GET /api', () => {
  let newDemoObject: { id: string };

  it('should return a message', async () => {
    const res = await axios.get(`/api`);

    expect(res.status).toBe(200);
    expect(res.data).toEqual({ message: 'Hello API' });
  });

  it('should create and return a demo object', async () => {
    const res = await axios.post(`/api/demo`);

    expect(res.status).toBe(201);
    expect(res.data.name).toContain('demo name');

    newDemoObject = res.data;
  });

  it('should get demo object by id', async () => {
    const res = await axios.get(`/api/demo/${newDemoObject.id}`);

    expect(res.status).toBe(200);
    expect(res.data).toMatchObject(newDemoObject);
  });

  it('should get all demo object', async () => {
    const res = await axios.get(`/api/demo`);

    expect(res.status).toBe(200);
    expect(res.data.filter((row) => row.id === newDemoObject.id)).toMatchObject([newDemoObject]);
  });

  it('should delete demo object by id', async () => {
    const res = await axios.delete(`/api/demo/${newDemoObject.id}`);

    expect(res.status).toBe(200);
    expect(res.data).toMatchObject(newDemoObject);
  });

  it('should get all demo object', async () => {
    const res = await axios.get(`/api/demo`);

    expect(res.status).toBe(200);
    expect(res.data.filter((row) => row.id === newDemoObject.id)).toMatchObject([]);
  });
});

12. Запускаем e2e-тесты

Команды

./node_modules/.bin/nx run-many --exclude=@nestjs-mod-fullstack/source --all -t=e2e --skip-nx-cache=true --output-style=stream-without-prefixes

Вывод консоли

13. Так как теперь часть методов контроллера AppController использует PrismaClient нам нужно изменить юнит-тесты

Обновленный файл apps/server/src/app/app.controller.spec.ts

import { Test, TestingModule } from '@nestjs/testing';

import { FakePrismaClient, PrismaModule } from '@nestjs-mod/prisma';
import { AppController } from './app.controller';
import { AppService } from './app.service';

describe('AppController', () => {
  const appFeatureName = 'app';
  let app: TestingModule;

  beforeAll(async () => {
    app = await Test.createTestingModule({
      imports: [
        PrismaModule.forRoot({
          environments: { databaseUrl: 'fake' },
          staticConfiguration: {
            featureName: appFeatureName,
            prismaModule: { PrismaClient: FakePrismaClient },
          },
        }),
      ],
      controllers: [AppController],
      providers: [AppService],
    }).compile();
  });

  describe('getData', () => {
    it('should return "Hello API"', () => {
      const appController = app.get<AppController>(AppController);
      expect(appController.getData()).toEqual({ message: 'Hello API' });
    });
  });
});

14. Запускаем юнит-тесты серверного приложения

Команды

./node_modules/.bin/nx run server:test --passWithNoTests

Вывод консоли

$  ./node_modules/.bin/nx run server:test --passWithNoTests
