Prerequisites

NodeJS https://nodejs.org/en/

Typescript https://www.typescriptlang.org/

PostgresQL https://www.postgresql.org/

Redis https://redis.io/

RabbitMQ https://www.rabbitmq.com

Getting started

# 1. Clone the repository or click on "Use this template" button.
npx degit rubiin/ultimate-nest my-nest-app

# 2. Enter your newly-cloned folder.
cd ultimate-nest

# 3. Create Environment variables file.
cp env/.env.sample env/.env.dev

# 4. Install dependencies (preferred: pnpm)
 pnpm install
 npm install
 yarn install

[!NOTE] If you face any issues with dependencies when using yarn or npm, stick to pnpm for now

[!NOTE] Env files are kept in env folder. The config validation allows 4 environment ['dev', 'prod', 'test','stage']. The env file name should be of format .env.[environment] Ex. (.env.dev). The env to use should be provided while running any script as NODE_ENV=dev npm run dev

Available Scripts

• npm run start - Start application
• npm run start:dev - Start application in watch mode
• npm run start:prod - Start built application
• npm run start:hmr - Start application with hot module replacement
• npm run lint - Uses oxlint to lint all the files inside src with config provided in .oxlintrx.json
• npm run orm migration:create - Uses Mikroorm to create a migration file
• npm run orm migration:up - This command is used to run availablexisting migration files.
• npm run orm migration:down - This command is used to rollback migration.
• npm run orm seeder:run - This command is used to run existing seeders in src/common/database.

All the scripts require NODE_ENV flag

Additionally, you can also see the scripts in justfile which is a cross platform task runner. You can use it by installing just and then running just <script>. Ex. just build

Setup

• First if you don't want to use any libs from like redis, mailer etc. replace them from the config.module.ts
  • You will also need to remove the config from validate.config.ts from line load: []
  • Also remove the unwanted config variables from the env file

Migration and seeding(optional)

Migrations are used to update the database schema. The migration files are stored in migrations directory.

NODE_ENV=dev npm run orm migration:up # applies migration for dev env

Seeding is used to insert data into the database. The seeding files are stored in common/database/seeders directory.

USER_PASSWORD=Test@1234 NODE_ENV=dev npm run orm seeder:run   # seeds data for dev env with all user password set as Test@1234

Seeding is optional

Start application

• NODE_ENV=dev npm run start
• View automatically generated swagger api docs by browsing to http://localhost:[port]/docs
• View automatically generated swagger stats dashboard by browsing to http://localhost:[port]/stats. The username and password is the values set in the env file under SWAGGER_USERNAME and SWAGGER_PASS respectively

Authentication

This applications uses JSON Web Token (JWT) to handle authentication. The token is passed with each request using the Authorization header with Token scheme. The JWT authentication middleware handles the validation and authentication of the token.

Deployment

You need to have docker and docker-compose installed. The image environment variable values can be found at the compose file

ENV=dev sh ./scripts/deploy.sh   # deploys dev environment (.env.dev used)
ENV=prod sh ./scripts/deploy.sh   # deploys prod environment (.env.prod used)
