Content Sources Priority

1. Remote API (if --api-url provided)
2. Local database (if --db points to valid database)
3. Mock content (if --mock=true or fallback)

🔌 serve Command

Runtime API server - provides HTTP endpoints for content management and server-hosted static site enhancement.

insertr serve [flags]

Flags

Flag	Description	Default
--port, -p	HTTP server port	8080
--dev-mode	Enable development mode features	false

Examples

# Development server
./insertr serve --dev-mode

Server-Hosted Static Sites

When running insertr serve, the server automatically:

• Registers sites from insertr.yaml configuration
• Enhances static files with latest database content
• Auto-updates files when content changes via API
• Creates backups of original files (if enabled)

Live Enhancement Process:

1. Content updated via API → Database updated
2. If site has auto_enhance: true → File enhancement triggered
3. Static files updated in-place → Changes immediately live

API Endpoints

When running insertr serve, these endpoints are available:

Health Check

• GET /health - Server health status

Content Management

• GET /api/content?site_id={site} - Get all content for site
• GET /api/content/{id}?site_id={site} - Get single content item
• GET /api/content/bulk?site_id={site}&ids[]={id1}&ids[]={id2} - Get multiple items
• POST /api/content - Create or update content (upsert)
• DELETE /api/content/{id}?site_id={site} - Delete content

⚙️ Configuration

YAML Configuration File

Default file: insertr.yaml

# Database configuration
database:
  path: "./insertr.db"        # SQLite file or PostgreSQL connection

# Remote API configuration  
api:
  url: ""                     # Content API URL
  key: ""                     # API key

# Server configuration
server:
  port: 8080                  # HTTP port
  dev_mode: false             # Development mode

# Build configuration
build:
  input: "./src"              # Default input directory
  output: "./dist"            # Default output directory

# Global settings
site_id: "demo"              # Site identifier
mock_content: false          # Use mock data

Environment Variables

All configuration can be set via environment variables:

export INSERTR_DB_PATH="./content.db"
export INSERTR_API_URL="https://api.example.com"
export INSERTR_API_KEY="your-api-key"
export INSERTR_SITE_ID="production"

./insertr serve

Configuration Precedence

1. CLI flags (highest priority)
2. Environment variables
3. YAML configuration file
4. Built-in defaults (lowest priority)

📋 Usage Patterns

Development Workflow

# Start full development environment
just dev                     # Uses justfile for convenience

# Manual development setup
./insertr serve --dev-mode --db ./dev.db &
npm run demo                 # Start demo site

# Hot reload development
air                         # Uses .air.toml configuration

Production Deployment

# Build static site with content
./insertr enhance ./src --output ./dist --api-url https://api.prod.com

# Start production API server
./insertr serve --db "postgresql://user:pass@db:5432/prod"

# With custom configuration
./insertr --config ./production.yaml serve

CI/CD Integration

# GitHub Actions example
- name: Build with Insertr
  run: |
    ./insertr enhance ./public --output ./dist
    
- name: Deploy enhanced site
  uses: peaceiris/actions-gh-pages@v3
  with:
    publish_dir: ./dist

🚨 Error Handling

Common Issues

Database Connection Errors:

# Check database path
./insertr --db ./nonexistent.db serve
# Error: failed to initialize database

# Solution: Verify database path or use --mock for development
./insertr serve --dev-mode  # Creates ./insertr.db automatically

Port Already in Use:

# Error: listen tcp :8080: bind: address already in use

# Solution: Use different port
./insertr serve --port 3001

Missing Input Directory:

# Error: Input directory does not exist

# Solution: Verify path exists
ls -la ./src
./insertr enhance ./src

🔍 Debugging

Verbose Logging

# Enable development mode for more detailed output
./insertr serve --dev-mode

# Check server health
curl http://localhost:8080/health

Configuration Validation

# Test configuration loading
./insertr --config ./test.yaml --help

# Verify environment variables
./insertr serve --help  # Shows resolved configuration values
