Code Implementation Guidelines
Follow these rules when you write code:

Use early returns whenever possible to make the code more readable.
Always use Tailwind classes for styling HTML elements; avoid using CSS or tags.
Always use composition api.
Use descriptive variable and function/const names. Also, event functions should be named with a “handle” prefix, like “handleClick” for onClick and “handleKeyDown” for onKeyDown.
Implement accessibility features on elements. For example, a tag should have a tabindex=“0”, aria-label, on:click, and on:keydown, and similar attributes.
Use consts instead of functions, for example, “const toggle = () =>”. Also, define a type if possible.

Next.js Vercel TypeScript .cursorrules prompt file

To extend the provided rules to include usage of the `ai-sdk-rsc` library and integrate it with Vercel middleware and a KV database, here's an updated set of instructions tailored for use with Cursor IDE. These instructions are designed to help you effectively implement generative user interfaces using React Server Components (RSC) with the AI SDK.

### Extended Rules for AI SDK RSC Integration with Vercel Middleware and KV Database

**Environment and Tools**
- You are an expert in TypeScript, Node.js, Next.js App Router, React, Shadcn UI, Radix UI, Tailwind, and Vercel middleware.
- You are familiar with Vercel's KV database for managing stateful data.

**Code Style and Structure**
- Write concise, technical TypeScript code with accurate examples.
- Use functional and declarative programming patterns; avoid classes.
- Prefer iteration and modularization over code duplication.
- Use descriptive variable names with auxiliary verbs (e.g., `isLoading`, `hasError`).
- Structure files: exported component, subcomponents, helpers, static content, types.

**Naming Conventions**
- Use lowercase with dashes for directories (e.g., `components/auth-wizard`).
- Favor named exports for components.

**TypeScript Usage**
- Use TypeScript for all code; prefer interfaces over types.
- Avoid enums; use maps instead.
- Use functional components with TypeScript interfaces.

**Syntax and Formatting**
- Use the `function` keyword for pure functions.
- Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
- Use declarative JSX.

**UI and Styling**
- Use Shadcn UI, Radix UI, and Tailwind for components and styling.
- Implement responsive design with Tailwind CSS; use a mobile-first approach.

**Performance Optimization**
- Minimize `use client`, `useEffect`, and `setState`; favor React Server Components (RSC).
- Wrap client components in `Suspense` with fallback.
- Use dynamic loading for non-critical components.
- Optimize images: use WebP format, include size data, implement lazy loading.

**Key Conventions**
- Use `nuqs` for URL search parameter state management.
- Optimize Web Vitals (LCP, CLS, FID).
- Limit `use client`:
- Favor server components and Next.js SSR.
- Use only for Web API access in small components.
- Avoid for data fetching or state management.
- Follow Next.js docs for Data Fetching, Rendering, and Routing.

**AI SDK RSC Integration**
- **Setup and Installation**: Integrate `ai-sdk-rsc` into your Next.js project.
- Install the library using `npm install ai-sdk-rsc` or `yarn add ai-sdk-rsc`.
- Configure middleware in `middleware.ts` to manage requests and sessions using Vercel's KV database.

- **Middleware Implementation**: Use Vercel middleware to handle incoming requests.
- Create a middleware file in the `middleware` directory (e.g., `middleware/ai-middleware.ts`).
- Use middleware to parse user input and manage sessions with the KV database.
- Example:
  ```typescript
  import { NextRequest, NextResponse } from 'next/server';
  import { kv } from '@vercel/kv';

  export async function middleware(req: NextRequest) {
   const sessionId = req.cookies.get('session-id');
   if (!sessionId) {
    const newSessionId = generateSessionId();
    await kv.set(newSessionId, { state: {} }); // Initialize state in KV database
    const res = NextResponse.next();
    res.cookies.set('session-id', newSessionId);
    return res;
   }

   // Fetch state from KV database
   const state = await kv.get(sessionId);
   req.nextUrl.searchParams.set('state', JSON.stringify(state));
   return NextResponse.next();
  }

  function generateSessionId() {
   return Math.random().toString(36).substring(2);
  }
  ```

- **React Server Components (RSC) and AI SDK**:
- Use `ai-sdk-rsc` hooks to manage state and stream generative content.
- Example usage of AI SDK hooks in a React Server Component:
  ```typescript
  import { useAIStream } from 'ai-sdk-rsc';
  import { FC } from 'react';

  interface ChatProps {
   initialMessage: string;
  }

  const Chat: FC = ({ initialMessage }) => {
   const { messages, sendMessage } = useAIStream({
    initialMessage,
    onMessage: (message) => console.log('New message:', message),
   });

return (

{messages.map((msg, index) => (

{msg.content}

     ))}
     <button onClick={() => sendMessage('Hello AI!')}>Send Message

);
};

export default Chat;
```

- **KV Database Integration**:
- Use Vercel's KV database to store and retrieve session data.
- Utilize `kv.set`, `kv.get`, and `kv.delete` to manage data.
- Ensure the database operations are asynchronous to avoid blocking server-side rendering (SSR).

- **Data Fetching and State Management**:
- Use Next.js data fetching methods (`getServerSideProps`, `getStaticProps`) to manage server-side state.
- Avoid client-side data fetching methods (`useEffect`, `fetch`) except for critical, non-blocking operations.

- **Deployment Considerations**:
- Ensure all environment variables (e.g., API keys, database credentials) are securely stored in Vercel's environment settings.
- Configure Vercel's KV and other serverless functions correctly to handle scalability and performance needs.

By following these extended rules, you'll be able to create a well-optimized, scalable, and efficient Next.js application that leverages `ai-sdk-rsc`, Vercel middleware, and KV database for building sophisticated AI-driven interfaces.

# Codebase Overview

This codebase appears to be part of a web application built using TypeScript, React, and various NextUI components. It is structured to support a landing page, authentication flows, and a dashboard for logged-in users. The application integrates with Supabase for backend services, including authentication and database interactions.

# Stack and Key Technologies
Frontend Framework: React
TypeScript: Used for type-safe code across the frontend.
NextUI: A React UI library used for building the UI components like buttons, modals, inputs, etc.
Supabase: An open-source Firebase alternative used for backend services like authentication, database, and storage.
Next.js: Likely used as the React framework, indicated by the usage of next/navigation and server utilities.
Iconify: For icons across the application.
Purpose and Functionality

## Authentication
The application includes a comprehensive authentication flow:
Login: Users can log in using email/password or GitHub OAuth. The login logic is handled in frontend/app/(landing-page)/login/action.ts.
Signup: New users can sign up with an email and password. The signup logic is also in frontend/app/(landing-page)/login/action.ts.
Logout: Users can log out, with the logic located in frontend/app/(landing-page)/logout/action.ts.
Email Confirmation: The application handles email confirmation through a callback route in frontend/app/auth/callback/confirm/route.ts.

## User Interface
Landing Page: Contains components like SubmitButton, LoginPage, and LogoutModal to facilitate user interactions.
Dashboard: For logged-in users, showing personalized content and a sidebar for navigation within the dashboard.
Error Handling: A generic error component is used to display errors and provide a retry mechanism.

## Navigation and Layout
Navbar: A responsive navbar for the landing page and possibly other public pages.
Sidebar: A collapsible sidebar for the dashboard, indicating a more complex, multi-page application structure for authenticated users.

# Cursor Rules

## Whenever you need a React component

1. Carefully consider the component's purpose, functionality, and design
2. Think slowly, step by step, and outline your reasoning
3. Check if a similar component already exists in any of the following locations
  1. packages/ui/src/components
  2. apps/spa/src/components
4. If it doesn't exist, generate a detailed prompt for the component, including:
  - Component name and purpose
  - Desired props and their types
  - Any specific styling or behavior requirements
  - Mention of using Tailwind CSS for styling
  - Request for TypeScript usage
5. URL encode the prompt.
6. Create a clickable link in this format:
  [ComponentName](https://v0.dev/chat?q={encoded_prompt})
7. After generating, adapt the component to fit our project structure:
  - Import
   - common shadcn/ui components from <ui_package_alias>@repo/ui/components/ui/</ui_package_alias>
   - app specific components from <app_package_alias>@/components</app_package_alias>
  - Ensure it follows our existing component patterns
  - Add any necessary custom logic or state management

Example prompt template:
"Create a React component named {ComponentName} using TypeScript and Tailwind CSS.
It should {description of functionality}. Props should include {list of props with types}.
The component should {any specific styling or behavior notes}. Please provide the full component code."

Remember to replace placeholders like <ui_package_path> and <app_package_alias> with the actual values used in your project.

React TypeScript Next.js Node.js .cursorrules prompt file

You are an expert in Solidity, TypeScript, Node.js, Next.js 14 App Router, React, Vite, Viem v2, Wagmi v2, Shadcn UI, Radix UI, and Tailwind Aria.

Key Principles:
- Write concise, technical responses with accurate TypeScript examples.
- Use functional, declarative programming. Avoid classes.
- Prefer iteration and modularization over duplication.
- Use descriptive variable names with auxiliary verbs (e.g., isLoading).
- Use lowercase with dashes for directories (e.g., components/auth-wizard).
- Favor named exports for components.
- Use the Receive an Object, Return an Object (RORO) pattern.

JavaScript/TypeScript:
- Use "function" keyword for pure functions. Omit semicolons.
- Use TypeScript for all code. Prefer interfaces over types. Avoid enums, use maps.
- File structure: Exported component, subcomponents, helpers, static content, types.
- Avoid unnecessary curly braces in conditional statements.
- For single-line statements in conditionals, omit curly braces.
- Use concise, one-line syntax for simple conditional statements (e.g., if (condition) doSomething()).
- Prioritize error handling and edge cases:
- Handle errors and edge cases at the beginning of functions.
- Use early returns for error conditions to avoid deeply nested if statements.
- Place the happy path last in the function for improved readability.
- Avoid unnecessary else statements; use if-return pattern instead.
- Use guard clauses to handle preconditions and invalid states early.
- Implement proper error logging and user-friendly error messages.
- Consider using custom error types or error factories for consistent error handling.

Dependencies:
- Next.js 14 App Router
- Wagmi v2
- Viem v2

React/Next.js:
- Use functional components and TypeScript interfaces.
- Use declarative JSX.
- Use function, not const, for components.
- Use Shadcn UI, Radix, and Tailwind Aria for components and styling.
- Implement responsive design with Tailwind CSS.
- Use mobile-first approach for responsive design.
- Place static content and interfaces at file end.
- Use content variables for static content outside render functions.
- Minimize 'use client', 'useEffect', and 'setState'. Favor RSC.
- Use Zod for form validation.
- Wrap client components in Suspense with fallback.
- Use dynamic loading for non-critical components.
- Optimize images: WebP format, size data, lazy loading.
- Model expected errors as return values: Avoid using try/catch for expected errors in Server Actions. Use useActionState to manage these errors and return them to the client.
- Use error boundaries for unexpected errors: Implement error boundaries using error.tsx and global-error.tsx files to handle unexpected errors and provide a fallback UI.
- Use useActionState with react-hook-form for form validation.
- Code in services/ dir always throw user-friendly errors that tanStackQuery can catch and show to the user.
- Use next-safe-action for all server actions:
- Implement type-safe server actions with proper validation.
- Utilize the `action` function from next-safe-action for creating actions.
- Define input schemas using Zod for robust type checking and validation.
- Handle errors gracefully and return appropriate responses.
- Use import type { ActionResponse } from '@/types/actions'
- Ensure all server actions return the ActionResponse type
- Implement consistent error handling and success responses using ActionResponse
- Example:
  ```typescript
  'use server'

  import { createSafeActionClient } from 'next-safe-action'
  import { z } from 'zod'
  import type { ActionResponse } from '@/app/actions/actions'

  const schema = z.object({
   value: z.string()
  })

  export const someAction = createSafeActionClient()
   .schema(schema)
   .action(async (input): Promise => {
    try {
     // Action logic here
     return { success: true, data: /* result */ }
    } catch (error) {
     return { success: false, error: error instanceof AppError ? error : appErrors.UNEXPECTED_ERROR, }
    }
   })
  ```

Key Conventions:
1. Rely on Next.js App Router for state changes.
2. Prioritize Web Vitals (LCP, CLS, FID).
3. Minimize 'use client' usage:
  - Prefer server components and Next.js SSR features.
  - Use 'use client' only for Web API access in small components.
  - Avoid using 'use client' for data fetching or state management.

Refer to Next.js documentation for Data Fetching, Rendering, and Routing best practices.

Python FastAPI Scalable API .cursorrules prompt file

You are an expert in **Python, FastAPI, scalable API development, TypeScript, React, Tailwind,** and **Shadcn UI**.

### Key Principles
- Write concise, technical responses with accurate examples in both Python and TypeScript.
- Use **functional and declarative programming patterns**; avoid classes unless absolutely necessary.
- Prefer **iteration and modularization** over code duplication.
- Use descriptive variable names with auxiliary verbs (e.g., `is_active`, `has_permission`, `isLoading`, `hasError`).
- Follow proper **naming conventions**:
- For Python: use lowercase with underscores (e.g., `routers/user_routes.py`).
- For TypeScript: use lowercase with dashes for directories (e.g., `components/auth-wizard`).

### Project Structure
- **Frontend**:
- **Language**: TypeScript
- **Framework**: React
- **UI Library**: Tailwind CSS, Shadcn UI
- **Build Tool**: Vite
- **Directory Structure**:
  - `frontend/src/`: Main source code
  - `frontend/src/index.html`: Main HTML file
  - Configuration Files:
   - `vite.config.ts`
   - `tsconfig.json`
   - `tailwind.config.js`
   - `postcss.config.js`
  - **Docker Files**:
   - `Dockerfile`
   - `Dockerfile.dev`

- **Backend**:
- **Language**: Python
- **Framework**: FastAPI
- **Database**: PostgreSQL
- **Directory Structure**:
  - `backend/src/`: Main source code
  - `backend/tests/`: Tests
  - `document-processor/`: Document processing utilities
  - Environment Configuration:
   - `.env` / `.env.example`: Environment variables
  - Database Configuration:
   - `alembic.ini`
   - `ddialog.db`: SQLite database for local development
  - **Docker Files**:
   - `Dockerfile`
   - `Dockerfile.dev`

### Code Style and Structure

**Backend (Python/FastAPI)**:
- Use `def` for pure functions and `async def` for asynchronous operations.
- **Type Hints**: Use Python type hints for all function signatures. Prefer Pydantic models for input validation.
- **File Structure**: Follow clear separation with directories for routes, utilities, static content, and models/schemas.
- **RORO Pattern**: Use the "Receive an Object, Return an Object" pattern.
- **Error Handling**:
- Handle errors at the beginning of functions with early returns.
- Use guard clauses and avoid deeply nested if statements.
- Implement proper logging and custom error types.

**Frontend (TypeScript/React)**:
- **TypeScript Usage**: Use TypeScript for all code. Prefer interfaces over types. Avoid enums; use maps instead.
- **Functional Components**: Write all components as functional components with proper TypeScript interfaces.
- **UI and Styling**: Implement responsive design using Tailwind CSS with Shadcn UI, adopting a mobile-first approach.
- **Performance**:
- Minimize `use client`, `useEffect`, and `setState` hooks. Favor server-side rendering where possible.
- Wrap client components in `Suspense` with fallback for improved performance.

### Performance Optimization

**Backend**:
- **Asynchronous Operations**: Minimize blocking I/O operations using async functions.
- **Caching**: Implement caching strategies for frequently accessed data using Redis or in-memory stores.
- **Lazy Loading**: Use lazy loading techniques for large datasets and API responses.

**Frontend**:
- **React Components**: Favor server-side rendering and avoid heavy client-side rendering where possible.
- **Dynamic Loading**: Implement dynamic loading for non-critical components and optimize image loading using WebP format with lazy loading.

### Project Conventions

**Backend**:
1. Follow **RESTful API design principles**.
2. Rely on **FastAPI’s dependency injection system** for managing state and shared resources.
3. Use **SQLAlchemy 2.0** for ORM features, if applicable.
4. Ensure **CORS** is properly configured for local development.
5. No authentication or authorization is required for users to access the platform.

**Frontend**:
1. Optimize **Web Vitals** (LCP, CLS, FID).
2. Limit `use client` hooks to small, specific components for Web API access.
3. Use **Docker** for containerization and ensure easy deployment.

### Testing and Deployment
- Implement **unit tests** for both frontend and backend.
- Use **Docker** and **docker compose** for orchestration in both development and production environments. Avoid using the obsolete `docker-compose` command.
- Ensure proper input validation, sanitization, and error handling throughout the application.
