    <li>First item</li>
    <li>Second item</li>
  </ul>
</div>

JSX

Output

<div className="container">
  <h1>Welcome to React</h1>

  <ul>
    <li>First item</li>
    <li>Second item</li>
  </ul>
</div>

Form Elements

Converting HTML forms with various input types

HTML

Input

<form onsubmit="handleSubmit()">
  <label for="email">Email:</label>
  <input type="email" id="email" required>

</div>

Self-Closing Tags

Proper JSX syntax for self-closing elements

HTML

  </header>
  <div class="card-body">
    <p>Card content goes here.</p>
    <button onclick="showMore()" class="btn btn-primary">
      Show More
    </button>
  </div>
</div>

JSX

Output

<div className="card" style={{border: "1px solid #ccc", padding: "20px"}}>
  <header className="card-header">
    <h2>Card Title</h2>
    <span className="badge">New</span>
  </header>
  <div className="card-body">
    <p>Card content goes here.</p>
    <button onClick={showMore} className="btn btn-primary">
      Show More
    </button>
  </div>
</div>

TypeScript Integration

Converting HTML to TypeScript-compatible JSX with interfaces

HTML

Input

<div class="user-profile">
  <img src="avatar.jpg" alt="User Avatar">

</div>

JSX

Output

interface UserProfileProps {
  className?: string;
  children?: React.ReactNode;
  [key: string]: any;
}

const UserProfile: React.FC<UserProfileProps> = ({ className, children, ...props }) => {
  return (
    <div className="user-profile" {...props}>
      <img src="avatar.jpg" alt="User Avatar" />
      <h3>John Doe</h3>
      <p>Software Developer</p>
      <button onClick={editProfile}>Edit Profile</button>
    </div>
  );
};

Performance Optimized Component

Converting with React.memo and performance optimizations

HTML

Input

<div class="product-list">
  <div class="product-item">
    <img src="product1.jpg" alt="Product 1">
    <h4>Product Name</h4>
    <p class="price">$29.99</p>
    <button onclick="addToCart(1)">Add to Cart</button>
  </div>
</div>

JSX

Output

import React, { memo, useCallback } from 'react';

const ProductList = memo(({ products, onAddToCart }) => {
  const handleAddToCart = useCallback((productId) => {
    onAddToCart(productId);
  }, [onAddToCart]);

  return (
    <div className="product-list">
      <div className="product-item">
        <img src="product1.jpg" alt="Product 1" />
        <h4>Product Name</h4>

Converting inline styles to styled-components syntax

HTML

Input

<div style="background: linear-gradient(45deg, #ff6b6b, #4ecdc4); padding: 20px; border-radius: 8px;">
  <h2 style="color: white; margin: 0;">Welcome</h2>
  <p style="color: rgba(255,255,255,0.9); margin-top: 10px;">Get started with our platform</p>
</div>

JSX

Output

import styled from 'styled-components';

const WelcomeContainer = styled.div`
  background: linear-gradient(45deg, #ff6b6b, #4ecdc4);
  padding: 20px;
  border-radius: 8px;
`;

const WelcomeTitle = styled.h2`
  color: white;
  margin: 0;
`;

const WelcomeText = styled.p`
  color: rgba(255,255,255,0.9);
  margin-top: 10px;
`;

const Welcome = () => (
  <WelcomeContainer>
    <WelcomeTitle>Welcome</WelcomeTitle>

  </WelcomeContainer>
);

Internationalization Support

Converting with i18n support for multi-language applications
