# Go Patterns

> This file extends the common patterns with Go specific content.

## Functional Options

```go
type Option func(*Server)

func WithPort(port int) Option {
    return func(s *Server) { s.port = port }
}

func NewServer(opts ...Option) *Server {
    s := &Server{port: 8080}
    for _, opt := range opts {
        opt(s)
    }
    return s
}
```

## Small Interfaces

Define interfaces where they are used, not where they are implemented.

## Dependency Injection

Use constructor functions to inject dependencies:

```go
func NewUserService(repo UserRepository, logger Logger) *UserService {
    return &UserService{repo: repo, logger: logger}
}
```
