## What it does

This skill guides the agent toward functional, declarative TypeScript patterns while avoiding classes entirely. It instructs the assistant to reduce `'use client'`, `useEffect`, and `setState` usage in favor of React Server Components, code splitting via dynamic imports, and lazy-loaded WebP images. Directories require lowercase names with hyphens, and boolean flags use descriptive prefixes such as `isLoading`.

The guidelines enforce a specific library ecosystem: Tailwind CSS, Radix UI, and Shadcn UI for the frontend, alongside Zustand or TanStack React Query for state management. Input validation relies on Zod schemas, while error handling uses guard clauses and early returns. Testing focuses on Jest with React Testing Library, supported by JSDoc comments for complex routines.

Codebases relying on class-based architectures or alternative component libraries will face direct friction with these instructions.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill optimized-nextjs-typescript -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/optimized-nextjs-typescript/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/optimized-nextjs-typescript/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill optimized-nextjs-typescript -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/optimized-nextjs-typescript/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill optimized-nextjs-typescript -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/optimized-nextjs-typescript/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Mindrally/skills optimized-nextjs-typescript
```

2. **Manually: put the files in place**
- File: `.github/skills/optimized-nextjs-typescript/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill optimized-nextjs-typescript -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Mindrally/skills --path optimized-nextjs-typescript
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/optimized-nextjs-typescript/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill optimized-nextjs-typescript -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Mindrally/skills/tree/HEAD/optimized-nextjs-typescript/SKILL.md

## When to use it
- enforce React Server Components over client-side state hooks
- validate user input with runtime Zod schemas
- manage client state using Zustand or TanStack React Query
- scaffold unit tests with Jest and React Testing Library

## Example prompts
- Build a Next.js server component for product cards with Zod schema validation.
- Refactor this client form to use guard clauses and Zustand for state.
- Write Jest and React Testing Library tests for the authentication helper.

# Optimized Next.js TypeScript Best Practices

You are an expert in creating highly optimized and maintainable Next.js solutions adhering to best practices in performance, security, and clean architecture principles.

## Code Style and Structure

- Write concise, technical TypeScript with functional, declarative patterns
- Avoid classes; favor composition and modularization
- Use descriptive variable names with auxiliary verbs (e.g., `isLoading`, `hasError`)
- Organize files with exported components, subcomponents, helpers, static content, and types
- Use lowercase with dashes for directory naming conventions

## Optimization Best Practices

- Minimize `'use client'`, `useEffect`, and `setState`; prioritize React Server Components
- Implement dynamic imports for code splitting
- Use mobile-first responsive design
- Optimize images with WebP format, size data, and lazy loading

## Error Handling and Validation

- Prioritize comprehensive error handling and edge cases
- Use early returns and guard clauses for preconditions
- Implement custom error types for consistency
- Validate user input rigorously

## UI and Styling

- Leverage modern frameworks: Tailwind CSS, Shadcn UI, Radix UI
- Maintain consistent, responsive design patterns

## State and Data Management

- Use Zustand or TanStack React Query for state and data fetching
- Implement Zod for schema validation

## Security and Performance

- Apply proper error handling and input validation
- Follow performance optimization techniques for load times and rendering

## Testing and Documentation

- Write Jest and React Testing Library unit tests
- Include JSDoc comments for IDE intellisense
- Document complex logic clearly
