# react-typescript-nextjs-nodejs-cursorrules-prompt-

A Cursor rule that pins down React, TypeScript, Next.js 14 and Node.js conventions: functional components, RORO, minimal use client.

## What it does

The file is a rule set Cursor reads and applies while generating code. It asks for TypeScript everywhere, the `function` keyword for components instead of `const`, no classes and no enums, named exports, and the RORO pattern — receive an object, return an object. Directories use lowercase with dashes, as in `components/auth-wizard`.

Error handling gets its own section. Guards and edge cases go at the top of a function, early returns keep nesting flat, and the happy path sits last. Expected errors in Server Actions are modelled as return values through `useActionState` rather than try/catch, while unexpected ones land in error boundaries via `error.tsx` and `global-error.tsx`. For server actions the rule points to `next-safe-action` with Zod schemas and a shared `ActionResponse` type.

On the UI side it names Shadcn UI, Radix and Tailwind Aria, mobile-first responsive design, and WebP images with lazy loading. It also pushes you to cut `use client`, `useEffect` and `setState` in favour of server components. One thing to watch: the rule declares a stack that includes Solidity, Viem v2 and Wagmi v2 — for a plain web app those lines are dead weight, so trim them before you commit the file. It does not apply on its own: the metadata sets `alwaysApply: false` with `globs` at `**/*`.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/react-typescript-nextjs-nodejs-cursorrules-prompt-.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/react-typescript-nextjs-nodejs-cursorrules-prompt-.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/react-typescript-nextjs-nodejs-cursorrules-prompt-.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/react-typescript-nextjs-nodejs-cursorrules-prompt-.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/react-typescript-nextjs-nodejs-cursorrules-prompt-.md`

## When to use it
- lock a team into one React and TypeScript style
- move data fetching off client components
- structure Server Action errors without nested try/catch
- wire type-safe actions with `next-safe-action` and Zod
- settle file naming and component layout

## Example prompts
- Build a login form component following the project rules: server component, Zod validation, named export
- Rewrite this Server Action with `next-safe-action` returning `ActionResponse` and early returns
- Scan this component for unnecessary `use client` and `useEffect` and suggest what moves to an RSC

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.
