Mondo Diaz 872464dec2 Add air-gapped deployment option for restricted environments

Added support for air-gapped and enterprise environments where npm package access is restricted, specifically addressing esbuild platform binary download issues.

**New Files:**
- Dockerfile.frontend.prebuilt: Alternative Dockerfile that uses pre-built Angular files
- DEPLOYMENT.md: Comprehensive deployment guide with two options

**Changes:**
- package.json: Added optionalDependencies for esbuild platform binaries
  - @esbuild/darwin-arm64
  - @esbuild/darwin-x64
  - @esbuild/linux-arm64
  - @esbuild/linux-x64

**Deployment Options:**

**Option 1 - Standard Build (current default):**
- Builds Angular in Docker
- Requires npm registry access
- Best for cloud/development

**Option 2 - Pre-built (for air-gapped):**
1. Build Angular locally: npm run build:prod
2. Change dockerfile in docker-compose.yml to Dockerfile.frontend.prebuilt
3. Docker only needs to copy files, no npm required
- No npm registry access needed during Docker build
- Faster, more reliable builds
- Best for enterprise/air-gapped/CI-CD

**Troubleshooting:**
See DEPLOYMENT.md for full troubleshooting guide including:
- esbuild platform binary issues
- Custom npm registry configuration
- Environment-specific recommendations

This addresses npm package access issues in restricted environments while maintaining flexibility for standard deployments.

Deployment Options

This project supports two deployment strategies for the Angular frontend, depending on your environment's network access.

Option 1: Standard Build (Internet Access Required)

Use the standard Dockerfile.frontend which builds the Angular app inside Docker.

Requirements:

Internet access to npm registry
Docker build environment

Usage:

./quickstart.sh
# or
docker-compose up -d --build

This uses Dockerfile.frontend which:

Installs npm dependencies in Docker
Builds Angular app in Docker
Serves with nginx

Option 2: Pre-built Deployment (Air-Gapped/Restricted Environments)

Use Dockerfile.frontend.prebuilt for environments with restricted npm access or when esbuild platform binaries cannot be downloaded.

Requirements:

Node.js 24+ installed locally
npm installed locally
No internet required during Docker build

Usage:

Step 1: Build Angular app locally

cd frontend
npm install  # Only needed once or when dependencies change
npm run build:prod
cd ..

Step 2: Update docker-compose.yml

Edit docker-compose.yml and change the frontend dockerfile:

  frontend:
    build:
      context: .
      dockerfile: Dockerfile.frontend.prebuilt  # <-- Change this line
    ports:
      - "4200:80"
    depends_on:
      - api

Step 3: Build and deploy

docker-compose up -d --build

This uses Dockerfile.frontend.prebuilt which:

Copies pre-built Angular files from frontend/dist/
Serves with nginx
No npm/node required in Docker

Troubleshooting

esbuild Platform Binary Issues

If you see errors like:

Could not resolve "@esbuild/darwin-arm64"

Solution 1: Use Option 2 (Pre-built) above

Solution 2: Add platform binaries to package.json (already included):

"optionalDependencies": {
  "@esbuild/darwin-arm64": "^0.25.4",
  "@esbuild/darwin-x64": "^0.25.4",
  "@esbuild/linux-arm64": "^0.25.4",
  "@esbuild/linux-x64": "^0.25.4"
}

Solution 3: Use custom npm registry with cached esbuild binaries

Custom NPM Registry

For both options, you can use a custom npm registry:

# Set in .env file
NPM_REGISTRY=http://your-npm-proxy:8081/repository/npm-proxy/

# Or inline
NPM_REGISTRY=http://your-proxy ./quickstart.sh

Recommendation

Development/Cloud: Use Option 1 (standard)
Air-gapped/Enterprise: Use Option 2 (pre-built)
CI/CD: Use Option 2 for faster, more reliable builds
