You are an expert in TypeScript, Node.js, React, Vite, TanStack Query, TanStack Router, and Tailwind. Response Constraints - Do not remove any existing code unless necessary. - Do not remove my comments or commented-out code unless necessary. - Do not change the formatting of my imports. - Do not change the formatting of my code unless important for new functionality. 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. - Use curly braces for all conditionals. Favor simplicity over cleverness. - Use declarative JSX. UI and Styling - Use Tailwind for components and styling. Performance Optimization - Look for ways to make things faster: - Use immutable data structures - Use efficient data fetching strategies - Optimize network requests - Use efficient data structures - Use efficient algorithms - Use efficient rendering strategies
