Предыдущая статья: Создание пустого Angular проекта и связь его с существующим сервером на NestJS

База данных будет подниматься через Docker Compose.

Миграции пишутся вручную и запускаются через Flyway мигратор.

Приложение имеет свой логин и пароль, который отличается от рутового.

Конфигурации для Docker Compose и Flyway генерируются через запуск NestJS-mod в режиме инфраструктуры.

1. Устанавливаем пакет для генерации Docker Compose и Flyway файлов

Команды

# Install all need dependencies
npm i --save @nestjs-mod/docker-compose @nestjs-mod/flyway

# Install all need dev-dependencies
npm i --save-dev node-flywaydb@3.0.7

Вывод консоли

$ npm i --save @nestjs-mod/docker-compose @nestjs-mod/flyway

2. Добавляем инфраструктурные модули в серверный код

Они будут использованны для генерации дополнительных файлов и скриптов.

4. Заполняем новые переменные окружения

После запуска серверного приложения в режиме инфраструктуы в файле переменных окружения появятся дополнительные переменные, примеры значений можно посмотреть в отчете по инфраструктуре apps/server/INFRASTRUCTURE.MD.

Обновленный файл .env

SERVER_PORT=3000
SERVER_ROOT_DATABASE_URL=postgres://postgres:postgres_password@localhost:5432/postgres?schema=public
SERVER_APP_DATABASE_URL=postgres://app:app_password@localhost:5432/app?schema=public

SERVER_POSTGRE_SQL_POSTGRESQL_USERNAME=postgres
SERVER_POSTGRE_SQL_POSTGRESQL_PASSWORD=postgres_password

6. Копируем обновленный файл с переменными окружения в качестве примера

Так как файл с переменными окружения находтся под gitignore, то при клонировании пустого проекта нужно заново вводить все знаечния для переменных окружения, для быстрого запуска проекта необходимо иметь пример заполненного файл с переменными окружения.

Команды

cp -r ./.env ./example.env

7. Создаем миграцию с примером создания таблицы

Команды

# Create migrations folder
mkdir -p ./apps/server/src/migrations

# Create empty migration
npm run flyway:create:server

Вывод консоли

$ npm run flyway:create:server

> @nestjs-mod-fullstack/source@0.0.0 flyway:create:server
> ./node_modules/.bin/nx run server:flyway-create-migration


> nx run server:flyway-create-migration

> echo 'select 1;' > ./apps/server/src/migrations/V`date +%Y%m%d%H%M`__NewMigration.sql

  server:flyway-create-migration

Flaky tasks can disrupt your CI pipeline. Automatically retry them with Nx Cloud. Learn more at https://nx.dev/ci/features/flaky-tasks

8. Описываем sql скрипт по созданию демо таблицы

Файл миграции apps/server/src/migrations/V202408112241__NewMigration.sql

CREATE TABLE IF NOT EXISTS "AppDemo"(
    id uuid DEFAULT uuid_generate_v4() NOT NULL,
    "name" varchar(128) NOT NULL,
    "createdAt" timestamp DEFAULT "now"() NOT NULL,
    "updatedAt" timestamp DEFAULT "now"() NOT NULL,
    CONSTRAINT "PK_APP_DEMO" PRIMARY KEY (id)
);

CREATE UNIQUE INDEX IF NOT EXISTS "UQ_APP_DEMO" ON "AppDemo"("name");

9. Запускаем базу данных

Команды
