Подключение PrismaORM в NestJS-mod приложение и проверка его работы через REST
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

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
> nx run server:test --passWithNoTests

В следующем посте я добавлю в NestJS-приложение генерацию Swagger документации и создам REST-клиента с которым будет взаимодействовать Angular-приложение...
