# GitHub Copilot TypeScript Configuration

## Type Safety
When generating TypeScript code:
- Enable strict mode
- Never use 'any'
- Use proper generics
- Define interfaces for objects

## Patterns
```typescript
// Prefer interfaces
interface User {
  id: string;
  email: string;
  role: 'admin' | 'user';
}

// Use generics
function findById<T extends { id: string }>(items: T[], id: string): T | undefined {
  return items.find(item => item.id === id);
}

// Type guards
function isUser(value: unknown): value is User {
  return (
    typeof value === 'object' &&
    value !== null &&
    'id' in value &&
    'email' in value
  );
}
```

## Utility Types
- Use Partial<T> for optional updates
- Use Pick<T, K> for selecting fields
- Use Omit<T, K> for excluding fields
- Use Record<K, V> for dictionaries
