Build applications on NestJS and Angular and run them in two versions: via PM2 and via Docker Compose

#pm2 #docker #fullstack #nestjs

To run the built applications in PM2 mode, the frontend will be embedded in the backend in the form of static files.

To run in the "Docker Compose" mode, the backend will be built as a Docker image, and the built-in static of the frontend will be transmitted via Nginx.

The database is start via "Docker Compose".

1. We install all the necessary packages and regenerate Prisma clients

After installing the packages, the generated Prisma clients are deleted, so you need to run the generation again.

Commands

# Install all need dependencies npm install --save @nestjs/serve-static dotenv wait-on # After installing the packages, the generated Prisma clients are deleted, so you need to run their generation again npm i && npm run generate

Console output 
npm install --save @nestjs/serve-static dotenv wait-on added 3 packages, and audited 2770 packages in 11s 331 packages are looking for funding run `npm fund` for details 18 vulnerabilities (6 moderate, 12 high) To address issues that do not require attention, run: npm audit fix To address all issues (including breaking changes), run: npm audit fix --force Run `npm audit` for details.

2. Adding a module for connecting static to the NestJS application

The NestJS-mod application has a special section for connecting this type of modules Core modules, but at this stage, to simplify understanding, such global things will be connected at the AppModule level.

Updated file apps/server/src/app/app.module.ts

import { createNestModule, NestModuleCategory } from '@nestjs-mod/common'; import { PrismaModule } from '@nestjs-mod/prisma'; import { ServeStaticModule } from '@nestjs/serve-static'; import { AppController } from './app.controller'; import { AppService } from './app.service'; import { join } from 'path'; export const { AppModule } = createNestModule({ moduleName: 'AppModule', moduleCategory: NestModuleCategory.feature, imports: [ PrismaModule.forFeature({ featureModuleName: 'app' }), ServeStaticModule.forRoot({ rootPath: join(__dirname, 'assets', 'client'), }), ], controllers: [AppController], providers: [AppService], });

3. Adding a new PM2 configuration file to run the built backend and frontend application

There will be only one application, since the static of the frontend application lies next to the built backend application.

Creating the file ecosystem-prod.config.json

{ "apps": [ { "name": "nestjs-mod-fullstack", "script": "node dist/apps/server/main.js", "node_args": "-r dotenv/config" } ] }

4. Adding new scripts and updating existing ones

There are a lot of scripts, but they are all needed for various application launch modes.

Groups of scripts similar in scope are combined into a certain header _____group name_____.

Updating the section with scripts in the package' file.json

9. Adding a Docker file that will build an image with the running backend

Сборка происходит в несколько этапов:

  1. Install only npm dependencies
  2. Install npm devDependencies necessary to generate additional code and packages
  3. Generating SDK for Prisma
  4. Removing unnecessary packages from node_modules
  5. Copy node_modules and applications to a new clean image

Creating the .docker/server' file.Dockerfile

10. Building a backend image

The script for starting the build is described in the package.json, since we have only one application that can be assembled into a Docker image, in the future, after the appearance of new Docker applications, the image building team will go to project.json

Commands

npm run docker:build:server:latest

11. Adding an Nginx config file to work with the frontend and backend through a single entry point

A typical config is used here, which I usually use in my projects, and other options can be found on the Internet.

Creating the file .docker/nginx/nginx.conf

map $sent_http_content_type $expires { "text/html" epoch; "text/html; charset=utf-8" epoch; default off; } map $http_upgrade $connection_upgrade { default upgrade; '' close; } upstream nestjs-mod-fullstack-server { server nestjs-mod-fullstack-server:8080; } server { listen 8080; server_name localhost; gzip on; gzip_proxied any; gzip_types text/plain application/xml text/css application/javascript application/json; gzip_min_length 1000; gzip_vary on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; client_max_body_size 50m; proxy_connect_timeout 5m; proxy_send_timeout 5m; proxy_read_timeout 5m; send_timeout 5m; proxy_max_temp_file_size 0; root /usr/share/nginx/html; index index.html; location /api { proxy_pass http://nestjs-mod-fullstack-server; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; proxy_set_header Host $host; proxy_set_header Origin $http_origin; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # kill cache add_header Last-Modified $date_gmt; add_header Cache-Control 'no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0'; if_modified_since off; expires off; etag off; } location / { expires $expires; proxy_redirect off; proxy_set_header Host $host; proxy_set_header Origin $http_origin; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_read_timeout 1m; proxy_connect_timeout 1m; proxy_intercept_errors on; error_page 404 =200 /index.html; root /usr/share/nginx/html; } }

12. Adding a new "Docker Compose" file with a single entry point that will launch the infrastructure and all applications

At the moment, 3 containers will be launched:

  1. Database Server
  2. Container for creating application databases and filling them through application migrations
  3. Backend application
  4. Nginx with built-in frontend files for routing requests to the backend

Creating the file .docker/docker-compose-full.yml

version: '3' networks: nestjs-mod-fullstack-network: driver: 'bridge' services: nestjs-mod-fullstack-postgre-sql: image: 'bitnami/postgresql:15.5.0' container_name: 'nestjs-mod-fullstack-postgre-sql' networks: - 'nestjs-mod-fullstack-network' volumes: - 'nestjs-mod-fullstack-postgre-sql-volume:/bitnami/postgresql' ports: - '5432:5432' healthcheck: test: - 'CMD-SHELL' - 'pg_isready -U postgres' interval: '5s' timeout: '5s' retries: 5 tty: true restart: 'always' environment: POSTGRESQL_USERNAME: '${SERVER_POSTGRE_SQL_POSTGRESQL_USERNAME}' POSTGRESQL_PASSWORD: '${SERVER_POSTGRE_SQL_POSTGRESQL_PASSWORD}' POSTGRESQL_DATABASE: '${SERVER_POSTGRE_SQL_POSTGRESQL_DATABASE}' nestjs-mod-fullstack-postgre-sql-migrations: image: 'node:20-bullseye-slim' container_name: 'nestjs-mod-fullstack-postgre-sql-migrations' networks: - 'nestjs-mod-fullstack-network' working_dir: '/app' volumes: - './../:/app' command: 'npm run db:create && npm run flyway:migrate' tty: true environment: NX_SKIP_NX_CACHE: 'true' SERVER_ROOT_DATABASE_URL: '${SERVER_ROOT_DATABASE_URL}' SERVER_APP_DATABASE_URL: '${SERVER_APP_DATABASE_URL}' depends_on: nestjs-mod-fullstack-postgre-sql: condition: 'service_healthy' nestjs-mod-fullstack-server: image: 'nestjs-mod-fullstack-server:latest' container_name: 'nestjs-mod-fullstack-server' networks: - 'nestjs-mod-fullstack-network' healthcheck: test: ['CMD-SHELL', 'npx -y wait-on --timeout= --interval=1000 --window --verbose --log http://localhost:8080/api/health'] interval: 30s timeout: 10s retries: 10 tty: true environment: SERVER_APP_DATABASE_URL: '${SERVER_APP_DATABASE_URL}' restart: 'always' depends_on: nestjs-mod-fullstack-postgre-sql: condition: service_healthy nestjs-mod-fullstack-postgre-sql-migrations: condition: service_completed_successfully nestjs-mod-fullstack-nginx: image: nginx:alpine container_name: 'nestjs-mod-fullstack-nginx' networks: - 'nestjs-mod-fullstack-network' volumes: - ../.docker/nginx:/etc/nginx/conf.d - ../dist/apps/client/browser:/usr/share/nginx/html depends_on: nestjs-mod-fullstack-server: condition: service_healthy ports: - '8080:8080' volumes: nestjs-mod-fullstack-postgre-sql-volume: name: 'nestjs-mod-fullstack-postgre-sql-volume'

13. Creating a new file with environment variables, where instead of the names of servers with localhost, the names of docker containers will stand

In this project, there will be manual duplication of all available variables from the root env file and substitution of server names, in a real project it will be necessary to automate this.

When deploying to a dedicated server, the environment variables are taken not from the file that lies inside the repository, but from the server environment variables.

Creating the file .docker/docker-compose-full.env

SERVER_ROOT_DATABASE_URL=postgres://postgres:postgres_password@nestjs-mod-fullstack-postgre-sql:5432/postgres?schema=public SERVER_APP_DATABASE_URL=postgres://app:app_password@nestjs-mod-fullstack-postgre-sql:5432/app?schema=public SERVER_POSTGRE_SQL_POSTGRESQL_USERNAME=postgres SERVER_POSTGRE_SQL_POSTGRESQL_PASSWORD=postgres_password SERVER_POSTGRE_SQL_POSTGRESQL_DATABASE=postgres

14. Creating a file with environment variables for watch mode in an Angular application

In this series of posts, various stands with dynamic domain names will not be considered, so for each variant of the stand it will be enough to create your own file with frontend environment variables and configure project.json.

Creating the file apps/client/src/environments/environment.ts

export const serverUrl = 'http://localhost:3000';
Enter fullscreen mode Exit fullscreen mode

15. Creating a file with environment variables for production mode in an Angular application

Since the frontend and backend are on the same domain, we leave the server address empty and the frontend will work with the backend at the address /api.

If the frontend and backend are divided into different domains, then you need to specify the domain and configure CORS policies on the backend and nginx, in these posts this point is omitted to simplify understanding of what is happening.

Creating the file apps/client/src/environments/environment.prod.ts

export const serverUrl = '';
Enter fullscreen mode Exit fullscreen mode

16. Adding rules for replacing files when building an Angular application in production mode

The config is very large, so below we show only what has been added.

Adding a few lines to the apps/client/project.json

{ // ... "targets": { "build": { // ... "configurations": { "production": { // ... "fileReplacements": [ { "replace": "apps/client/src/environments/environment.ts", "with": "apps/client/src/environments/environment.prod.ts" } ] } } } } }
Enter fullscreen mode Exit fullscreen mode

17. Updating the configuration of the Angular application to support multiple environment variables

Updating the file apps/client/src/app/app.config.ts

import { provideHttpClient } from '@angular/common/http'; import { ApplicationConfig, importProvidersFrom, provideZoneChangeDetection } from '@angular/core'; import { provideClientHydration } from '@angular/platform-browser'; import { provideRouter } from '@angular/router'; import { RestClientApiModule, RestClientConfiguration } from '@nestjs-mod-fullstack/app-angular-rest-sdk'; import { appRoutes } from './app.routes'; import { serverUrl } from '../environments/environment'; export const appConfig: ApplicationConfig = { providers: [ provideClientHydration(), provideZoneChangeDetection({ eventCoalescing: true }), provideRouter(appRoutes), provideHttpClient(), importProvidersFrom( RestClientApiModule.forRoot( () => new RestClientConfiguration({ basePath: serverUrl, }) ) ), ], };

18. We run unit tests and run applications in watch mode via PM2, followed by checking applications through E2E tests

Commands

npm run test npm run pm2-full:dev:start npm run test:e2e npm run pm2-full:dev:stop
Enter fullscreen mode Exit fullscreen mode

19. Прогоняем юнит-тесты и запускаем приложения в прод-режиме через PM2 с последующей проверкой приложений через E2E-тесты

Commands

npm run test npm run pm2-full:prod:start npm run test:e2e npm run pm2-full:prod:stop
Enter fullscreen mode Exit fullscreen mode

20. We are changing the settings of E2E tests for the backend, since in the prod mode via Docker Compose, applications have a single entry point and the port differs from what is specified in watch mode

The ports are specifically used differently in each mode in order to show more different cases in the development and deployment of applications.

Updated file apps/server-e2e/src/support/test-setup.ts

/* eslint-disable */ import axios from 'axios'; module.exports = async function () { // Configure axios for tests to use. const host = process.env.HOST ?? 'localhost'; const port = process.env.PORT ?? '3000'; axios.defaults.baseURL = process.env['BASE_URL'] || `http://${host}:${port}`; };
Enter fullscreen mode Exit fullscreen mode

21. We run unit tests and run applications in prod mode through Docker Compose, followed by checking applications through E2E tests

Commands

npm run test npm run docker-compose-full:prod:start npm run docker-compose-full:prod:test:e2e npm run docker-compose-full:prod:stop
Enter fullscreen mode Exit fullscreen mode

22. After the current developments and before the commit, we run through all the generation, formatting of the code and running unit tests

Commands

npm run manual:prepare
Enter fullscreen mode Exit fullscreen mode
