User Guide

Learn how to effectively use our HTML to JSX converter and understand the key differences between HTML and JSX.

Getting Started

Using our HTML to JSX converter is simple and straightforward. Follow these steps to convert your HTML code:

Step-by-Step Instructions

  1. Paste your HTML code into the left input area
  2. Configure conversion options if needed
  3. Click the "Convert to JSX" button
  4. Review the converted JSX code in the right output area
  5. Copy or download the converted code

Key Differences: HTML vs JSX

Understanding the differences between HTML and JSX is crucial for effective React development. Here are the main differences our converter handles:

1. Attribute Names

JSX uses camelCase for attribute names, while HTML uses lowercase or kebab-case.

HTML

<div class="container">
  <label for="email">Email</label>
  <input tabindex="1" readonly>
</div>

JSX

<div className="container">
  <label htmlFor="email">Email</label>
  <input tabIndex="1" readOnly />
</div>

2. Self-Closing Tags

JSX requires all tags to be properly closed, including self-closing tags.

HTML

<img src="image.jpg" alt="Image">
<input type="text">
<br>
<hr>

JSX

<img src="image.jpg" alt="Image" />
<input type="text" />
<br />
<hr />

3. Style Attributes

JSX requires style attributes to be objects with camelCase properties.

HTML

<div style="background-color: blue; font-size: 16px;">
  Content
</div>

JSX

<div style={{backgroundColor: "blue", fontSize: "16px"}}>
  Content
</div>

4. Event Handlers

JSX uses camelCase for event handlers and expects function references.

HTML

<button onclick="handleClick()">
  Click me
</button>

JSX

<button onClick={handleClick}>
  Click me
</button>

Professional Development Features

🔷 TypeScript Integration

Generate TypeScript-compatible JSX with proper type definitions:

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

const Component: React.FC<Props> = ({ className, children, ...props }) => {
  return (
    <div className={className} {...props}>
      {children}
    </div>
  );
};

🧪 Testing Integration

Automatically generate test files and add testing attributes:

Test IDs Added

<button data-testid="button-abc123">
  Click me
</button>

Generated Test

test('renders button', () => {
  render(<Component />);
  expect(screen.getByTestId('button-abc123')).toBeInTheDocument();
});

⚡ Performance Optimization

Automatically add React performance optimizations:

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

const Component = memo(({ items, onItemClick }) => {
  const sortedItems = useMemo(() =>
    items.sort((a, b) => a.name.localeCompare(b.name)), [items]
  );

  const handleClick = useCallback((id) => {
    onItemClick(id);
  }, [onItemClick]);

  return (
    <div>
      {sortedItems.map(item => (
        <button key={item.id} onClick={() => handleClick(item.id)}>
          {item.name}
        </button>
      ))}
    </div>
  );
});

Best Practices

💡 Tips for Better Conversion

  • Always review the converted code before using it in production
  • Test the converted JSX in your React environment
  • Use the validation feature to catch potential issues
  • Consider breaking large HTML blocks into smaller components
  • Update event handlers to use proper React patterns
  • Replace inline styles with CSS classes when appropriate
  • Use TypeScript mode for better type safety
  • Enable performance optimizations for production components
  • Add test IDs for better testing coverage
  • Use the analytics dashboard to track your conversion patterns

Common Issues and Solutions

Issue: Unclosed Tags

Problem: HTML with unclosed tags will cause JSX syntax errors.

Solution: Use our validation feature to identify unclosed tags and fix them before conversion.

Issue: Complex Event Handlers

Problem: Inline JavaScript in HTML event handlers needs manual adjustment.

Solution: Replace inline JavaScript with proper React event handler functions.

Issue: Reserved Keywords

Problem: Some HTML attributes conflict with JavaScript reserved words.

Solution: Our converter automatically handles these cases (e.g., class → className).
