# Development Workflow Guide
Complete development workflows for ggen projects following marketplace-first principles.
## Marketplace-First Development
### 1. Search & Discover
```bash
# Search for existing solutions first
ggen market search "rust web service"
ggen market search "authentication"
ggen market categories
```
### 2. Install Dependencies
```bash
# Install proven packages from marketplace
ggen market add "rust-axum-service"
ggen market add "postgresql-database"
ggen market add "docker-compose"
```
### 3. Initialize & Generate
```bash
# Initialize project structure
ggen lifecycle run init
# Generate using marketplace templates
ggen template generate rust-axum-service:user-service.tmpl
ggen template generate postgresql-database:schema.tmpl
```
### 4. Develop & Test
```bash
# Run comprehensive testing
ggen lifecycle run test
# Check production readiness
ggen lifecycle readiness
```
### 5. Deploy Safely
```bash
# Validate deployment requirements
ggen lifecycle validate --env production
# Deploy with confidence
ggen lifecycle run deploy --env production
```
## Complete Examples
### Microservices Project
```bash
cd examples/microservices-architecture/
ggen market search "microservices"
ggen market add "microservices-architecture"
ggen lifecycle run init
ggen template generate microservices-architecture:api-gateway.tmpl
ggen lifecycle run deploy --env production
```
### AI-Powered Service
```bash
cd examples/ai-code-generation/
ggen market search "ai service"
ggen market add "ai-service-templates"
ggen lifecycle run init
ggen ai generate "Create book management service"
ggen lifecycle run test
```
## Best Practices
1. **Search Before Building** - Always check marketplace first
2. **Use Proven Patterns** - Leverage marketplace packages
3. **Validate Early** - Use production readiness checks
4. **Deploy Safely** - Use lifecycle validation before deployment
