Add Docker Support and CI Pipeline for Backend

Description

This PR introduces two key enhancements:

1. Docker Integration: Adds configuration files and scripts to containerize the backend application and manage it using Docker Compose.
2. CI Pipeline: Sets up a GitHub Actions CI pipeline to automate the build process for the backend.

Changes

Docker Integration

• Added Docker Compose configuration:

  api:
      build:
        context: .
        dockerfile: Dockerfile.api
      container_name: hias-api
      environment:
        POSTGRES_USER: hias-user
        POSTGRES_PASSWORD: 123456
        POSTGRES_DB: hias
        POSTGRES_HOST: postgres
        NODE_ENV: production
      ports:
        - "5000:5000"
      depends_on:
        - postgres
      command: ["npm", "run", "start"]  

Created Dockerfile.api:

• Added a Dockerfile to containerize the backend API.
• Key Features:
  • Base Image: Node.js (version 18).
  • Working Directory: /app.
  • Build Steps:
    • Copies the package.json and package-lock.json.
    • Installs dependencies using npm install.
    • Copies all application files into the container.
    • Runs the backend using npm run start.

---

Updated package.json:

• Added a clean script to simplify build cleanup:

  "clean": "rm -rf dist"

Updated db.ts:

• Enhanced database configuration to support Docker deployment:

  host: process.env.DB_HOST, // Container name if using Docker

Added CI Pipeline for Backend:

• Implemented a GitHub Actions workflow to automate backend builds.
• Workflow Features:
  • Triggered on push and pull_request events to the main branch.
  • Automates the build process by compiling TypeScript to JavaScript.

---

Checklist

• Updated db.ts with Docker compatibility.
• Added Dockerfile.api for API containerization.
• Enhanced package.json with a clean script.
• Added a CI workflow for backend builds.

---

Next Steps

• Verify the Dockerized API functionality in production-like environments.
• Continuously monitor the CI pipeline for build integrity.
