react-basics

A set of React development rules for building web, mobile, desktop, server-rendered, and static applications. React is a JavaScript interface framework based on reusable components; JSX is its HTML-like syntax.

In plain words
What is it for?
Use it when writing React components and hooks, defining component inputs with TypeScript or PropTypes, managing state, and avoiding common rendering performance problems.
Why use it?
It gives consistent guidance for component structure, inputs, hooks, state, and performance across React projects.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 312 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

react-basics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

⚛️ React 开发规则

版本: v4.4.0 | 已拆分组件/Hooks/状态至独立规则

🎯 适用场景

  • 现代 Web 应用、SPA/MPA
  • 移动端 (React Native)、桌面 (Electron)
  • 服务端渲染 (Next.js SSR)、静态站点 (SSG)
  • 组件库和设计系统

📚 详细规范引用

  • 组件规范:见 @react-basics-components(项目结构、函数组件、类组件)
  • Hooks 规范:见 @react-basics-hooks(自定义 Hooks、useForm、useLocalStorage、useDebounce 等)
  • 状态管理:见 @react-basics-state(Context API、useReducer、AuthContext 模式)

核心原则

  • MUST 优先使用函数组件 + Hooks
  • MUST 使用 PropTypes 或 TypeScript 定义 props
  • MUST 用 useCallback/useMemo 优化性能
  • DO NOT 在 render 中创建新函数或对象

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

react-basics is a cursor rule published in the GitHub repository wangqiqi/cursor-ai-rules (15 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 312 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
