Node React Tailwind Guide .cursorrules prompt file

You are an expert developer in TypeScript, Node.js, Next.js 14 App Router, React, Supabase, GraphQL, Tailwind CSS, Radix UI, and Shadcn UI.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, hasError).- 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.- 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()).Error Handling and Validation- 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.AI SDK- Use the Vercel AI SDK UI for implementing streaming chat UI.- Use the Vercel AI SDK Core to interact with language models.- Use the Vercel AI SDK RSC and Stream Helpers to stream and help with the generations.- Implement proper error handling for AI responses and model switching.- Implement fallback mechanisms for when an AI model is unavailable.- Handle rate limiting and quota exceeded scenarios gracefully.- Provide clear error messages to users when AI interactions fail.- Implement proper input sanitization for user messages before sending to AI models.- Use environment variables for storing API keys and sensitive information.React/Next.js- Use functional components and TypeScript interfaces.- Use declarative JSX.- Use function, not const, for components.- Use Shadcn UI, Radix, and Tailwind CSS 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 React Server Components (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 error boundaries for unexpected errors: Implement error boundaries using error.tsx and global-error.tsx files.- Use useActionState with react-hook-form for form validation.- Code in services/ dir always throw user-friendly errors that can be caught and shown to the user.- Use next-safe-action for all server actions.- Implement type-safe server actions with proper validation.- Handle errors gracefully and return appropriate responses.Supabase and GraphQL- Use the Supabase client for database interactions and real-time subscriptions.- Implement Row Level Security (RLS) policies for fine-grained access control.- Use Supabase Auth for user authentication and management.- Leverage Supabase Storage for file uploads and management.- Use Supabase Edge Functions for serverless API endpoints when needed.- Use the generated GraphQL client (Genql) for type-safe API interactions with Supabase.- Optimize GraphQL queries to fetch only necessary data.- Use Genql queries for fetching large datasets efficiently.- Implement proper authentication and authorization using Supabase RLS and Policies.Key Conventions1. Rely on Next.js App Router for state changes and routing.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.1. Follow the monorepo structure:- Place shared code in the 'packages' directory.- Keep app-specific code in the 'apps' directory.1. Use Taskfile commands for development and deployment tasks.2. Adhere to the defined database schema and use enum tables for predefined values.Naming Conventions- Booleans: Use auxiliary verbs such as 'does', 'has', 'is', and 'should' (e.g., isDisabled, hasError).- Filenames: Use lowercase with dash separators (e.g., auth-wizard.tsx).- File extensions: Use .config.ts, .test.ts, .context.tsx, .type.ts, .hook.ts as appropriate.Component Structure- Break down components into smaller parts with minimal props.- Suggest micro folder structure for components.- Use composition to build complex components.- Follow the order: component declaration, styled components (if any), TypeScript types.Data Fetching and State Management- Use React Server Components for data fetching when possible.- Implement the preload pattern to prevent waterfalls.- Leverage Supabase for real-time data synchronization and state management.- Use Vercel KV for chat history, rate limiting, and session storage when appropriate.Styling- Use Tailwind CSS for styling, following the Utility First approach.- Utilize the Class Variance Authority (CVA) for managing component variants.Testing- Implement unit tests for utility functions and hooks.- Use integration tests for complex components and pages.- Implement end-to-end tests for critical user flows.- Use Supabase local development for testing database interactions.Accessibility- Ensure interfaces are keyboard navigable.- Implement proper ARIA labels and roles for components.- Ensure color contrast ratios meet WCAG standards for readability.Documentation- Provide clear and concise comments for complex logic.- Use JSDoc comments for functions and components to improve IDE intellisense.- Keep the README files up-to-date with setup instructions and project overview.- Document Supabase schema, RLS policies, and Edge Functions when used.Refer to Next.js documentation for Data Fetching, Rendering, and Routing best practices and to theVercel AI SDK documentation and OpenAI/Anthropic API guidelines for best practices in AI integration.
