React Component Builder

Generate production-ready React components with TypeScript, proper typing, and best practices.

Prompt Template

You are a senior React + TypeScript engineer. Generate a production-ready component.

Component name: {{component_name}}
Purpose: {{purpose}}
Props (with types): {{props}}
Behavior / state: {{behavior}}
Styling: {{styling}}
Accessibility requirements: {{a11y}}

Requirements:
- Function component, React 18+, hooks only
- Explicit TypeScript interface ({{component_name}}Props), no `any`
- Default export at the bottom
- Memoize with useCallback / useMemo only where it actually helps
- JSDoc on the component and exported types
- Semantic HTML + aria-* attributes
- forwardRef if it wraps an input/button

Deliver, in this order:
1. {{component_name}}.tsx — full implementation
2. {{component_name}}Props TypeScript interface, exported separately with JSDoc on each prop
3. {{component_name}}.test.tsx (React Testing Library, 2–3 tests covering key behaviors)
4. A 2–3 line usage example showing realistic props
5. Accessibility notes: ARIA labels used, keyboard navigation behavior, any screen-reader caveats

Example Output

// PriceTag.tsx
import { useState, useCallback } from "react";

/** Display a price with optional currency-toggle behavior. */
export interface PriceTagProps {
  amount: number;
  currency?: string;
  locale?: string;
}

export const PriceTag = ({ amount, currency = "USD", locale = "en-US" }: PriceTagProps) => {
  const [active, setActive] = useState(false);
  const toggle = useCallback(() => setActive(v => !v), []);
  return (
    <button onClick={toggle} aria-pressed={active} className="font-mono">
      {new Intl.NumberFormat(locale, { style: "currency", currency }).format(amount)}
    </button>
  );
};

export default PriceTag;

Tips

  • List every prop you actually need, one per line, with TS types — vague props lead to vague components.
  • In "behavior," describe what changes when the user interacts (clicks, types, hovers).
  • For complex components, generate twice and keep the cleaner version.
