type UserService struct {
db *sql.DB
bzzz *bzzz.Client
logger *log.Logger
}
func (s *UserService) CreateUser(ctx context.Context, user *User) error {
// Create user in database
if err := s.db.ExecContext(ctx, createUserSQL, user); err != nil {
return err
}
// Publish decision to BZZZ
return s.bzzz.Decisions.PublishCode(ctx, decisions.CodeDecision{
Task: "create_user",
Decision: fmt.Sprintf("Created user: %s", user.Email),
FilesModified: []string{"internal/users/service.go"},
Success: true,
})
}
```
#### Event-Driven Architecture
```python
# Event-driven microservice with BZZZ integration
class OrderProcessor:
def __init__(self, bzzz_client):
self.bzzz = bzzz_client
self.event_stream = bzzz_client.subscribe_events()
async def start_processing(self):
async for event in self.event_stream:
if event.type == "order_created":
await self.process_order(event.data)
async def process_order(self, order_data):
# Process order
result = await self.fulfill_order(order_data)
# Publish decision
await self.bzzz.decisions.publish_code(
task="process_order",
decision=f"Processed order {order_data['id']}",
success=result.success
)
