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 v2React/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.
