A progressive Node.js framework for building efficient and scalable server-side applications.

Nest framework TypeScript starter repository.

npm install

# development
npm run start

# watch mode
npm run start:dev

# production
npm run start:prod

This project includes a full Docker setup for NestJS + PostgreSQL + TypeORM migrations & seeders.

docker compose up -d

This command will:

• Start the NestJS app container (insurance_policy_app)
• Start the PostgreSQL container (insurance_policy_postgres)

docker compose run --rm migrate

This will execute all pending TypeORM migrations inside the container.

docker compose run --rm seed

Runs the seeders defined in src/db/seeders/ (e.g. role.seeder.ts, user.seeder.ts, etc.).

docker compose ps

You should see something like:

insurance_policy_postgres   Up   0.0.0.0:5432->5432/tcp
insurance_policy_app        Up   0.0.0.0:3000->3000/tcp

Once containers are up, the app is available at:

http://localhost:3000

http://localhost:3000/api

docker compose down

To reset all data (remove database volume):

docker compose down -v

Example:

npm run migration:generate src/db/migrations/AddUserColumn
npm run migration:run

🧠 Note: In Docker, you can also run migrations using:

docker compose run --rm migrate

Seeders populate initial data in the application.

# Local (requires npm dependencies)
npm run seed
npm run seed:dev

# Dockerized environment
docker compose run --rm seed

1. role.seeder.ts → create default roles
2. user.seeder.ts → create admin & default users
3. All seeders registered in main.seeder.ts

Once running, Swagger is available at:

http://localhost:3000/api

• JWT Authentication
• File Upload (JPEG, PNG, PDF)
• CORS Enabled
• Validation using class-validator

• .env is automatically loaded into Docker containers.
• Example configuration:

  DB_HOST=db
  DB_PORT=5432
  DB_USERNAME=postgres
  DB_PASSWORD=postgres
  DB_NAME=insurance_policy_db

Database data is stored in Docker volume pgdata:

docker volume ls

To clear database data:

docker compose down -v

• synchronize: false in data-source.ts
• Test migrations before deployment
• Backup production DB before running migrations
• Use strong passwords & secrets
• Set proper CORS origins
• Enable HTTPS in production
