# Next.js

Enforces Next.js conventions by restricting React hooks, keeping page.tsx on the server, and setting shadcn/ui as the default UI system.

## What it does

This prompt sets direct architectural boundaries for Next.js code generation. It forbids making `page.tsx` a client component, pushing all interactive logic into subcomponents inside `/components`. The instructions also establish `shadcn/ui` as the required design system, requiring `globals.css` to contain theme variables and Tailwind directives.

Component state management follows strict rules. The model uses a minimal hook footprint: `useState`, `useEffect`, `useCallback`, and `useMemo`. Persistent client state requires lazy initialization through `localStorage`. For non-reactive tasks like input focus or DOM measurements, the rules mandate `useRef` to prevent unnecessary re-renders. Functional updates are compulsory to avoid stale state closures.

Whenever a component exceeds a single responsibility, the agent must split it into smaller files. Accessibility labels rely on `sr-only` utility classes. Without Tailwind and `shadcn/ui` configured in your workspace, the generated components will fail to build.

## Install

### ChatGPT (native platform)

**How to use**
- Paste the text at the start of a chat or into project instructions

### Claude Code

**Manually: put the files in place**
- File: `.claude/commands/prompts.csv.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/f/prompts.chat/tree/HEAD/prompts.csv

## When to use it
- keep `page.tsx` as a pure server component
- enforce lazy initialization for `localStorage` state
- restrict component logic to a minimal hook set
- break oversized components into focused subcomponents
- implement accessible labels using `sr-only` classes

## Example prompts
- Build a settings form in Next.js that saves drafts to `localStorage`
- Create a product page with a server `page.tsx` and interactive `shadcn/ui` filters
- Refactor this dashboard component into smaller single-responsibility subcomponents

```text
# Next.js
- Use minimal hook set for components: useState for state, useEffect for side effects, useCallback for memoized handlers, and useMemo for computed values. Confidence: 0.85
- Never make page.tsx a client component. All client-side logic lives in components under /components, and page.tsx stays a server component. Confidence: 0.85
- When persisting client-side state, use lazy initialization with localStorage. Confidence: 0.85
- Always use useRef for stable, non-reactive state, especially for DOM access, input focus, measuring elements, storing mutable values, and managing browser APIs without triggering re-renders. Confidence: 0.85
- Use sr-only classes for accessibility labels. Confidence: 0.85
- Always use shadcn/ui as the component system for Next.js projects. Confidence: 0.85
- When setting up shadcn/ui, ensure globals.css is properly configured with all required Tailwind directives and shadcn theme variables. Confidence: 0.70
- When a component grows beyond a single responsibility, break it into smaller subcomponents to keep each file focused and improve readability. Confidence: 0.85
- State itself should trigger persistence to keep side-effects predictable, centralized, and always in sync with the UI. Confidence: 0.85
- Derive new state from previous state using functional updates to avoid stale closures and ensure the most accurate version of state. Confidence: 0.85
