TypeScript Development Guidelines

Core Requirements

• TypeScript must be used for all code generation
• Never use the any type as it will break the build
• Always use Shadcn and Tailwind CSS, but implement without using Card components
• Avoid typing components with React.FC
• Use const for component declarations instead of function
• Follow React's composable patterns

State Management and Performance

• Minimize use of useState and useEffect hooks
• Prefer computed state where possible
• Use useMemo and useCallback when necessary to prevent unnecessary re-renders
• Prioritize server actions and useActionState
• Fall back to fetch and API route handlers when server actions aren't suitable
• When components need to modify data, they should receive server actions as props

Component Architecture

• Prioritize server components whenever possible
• Create client components only when necessary
• Utilize Suspense and streaming capabilities where possible
• For components requiring specific functionality not tightly coupled to the component itself, create higher-order components
• Group related components, hooks, and functions in the same file when it makes semantic sense for easier distribution and usage

Forms and Data Handling

• Implement forms as server-side components
• Only use client components for dynamic operations (e.g., user registration sections)
• Always validate inputs using Zod in server actions and API endpoints
• Always HTML escape text content

Custom Hooks

• Create custom hooks to encapsulate specific logic when grouping useState and useEffect makes sense
• Custom hooks should be focused and reusable

Best Practices

• Group related components, hooks, and functions in the same file when it makes semantic sense for easier distribution and usage
• Follow consistent naming conventions
• Maintain clear separation of concerns
• Ensure proper error handling
• Implement proper type safety throughout the codebase
