Pros of card

• Vanilla JavaScript implementation, making it more versatile and framework-agnostic
• Supports a wider range of card types, including Diner's Club and Discover
• Offers more customization options for card appearance and formatting

Cons of card

• Less React-specific optimizations and integration
• Requires more setup and configuration for React projects
• May have a steeper learning curve for React developers

Code Comparison

react-credit-cards:

import Cards from 'react-credit-cards';

<Cards
  number={cardNumber}
  name={cardName}
  expiry={cardExpiry}
  cvc={cardCVC}
  focused={focused}
/>

card:

var card = new Card({
  form: 'form',
  container: '.card-wrapper',
  formSelectors: {
    numberInput: 'input#number',
    expiryInput: 'input#expiry',
    cvcInput: 'input#cvc',
    nameInput: 'input#name'
  }
});

react-credit-cards is more React-friendly and requires less setup, while card offers more flexibility but needs more configuration. The choice between them depends on the specific project requirements and the developer's preference for React-specific solutions versus more general JavaScript libraries.

Pros of qrcodejs

• Lightweight and simple to use, with no external dependencies
• Supports various output formats (canvas, table, SVG)
• Cross-browser compatible, including older versions of IE

Cons of qrcodejs

• Limited to QR code generation only, lacking credit card-specific features
• No built-in React integration, requiring additional setup for React projects
• Less actively maintained, with fewer recent updates

Code Comparison

qrcodejs:

var qrcode = new QRCode("qrcode", {
    text: "http://example.com",
    width: 128,
    height: 128,
    colorDark : "#000000",
    colorLight : "#ffffff",
    correctLevel : QRCode.CorrectLevel.H
});

react-credit-cards:

import Cards from 'react-credit-cards';

<Cards
  number={cardNumber}
  name={cardName}
  expiry={cardExpiry}
  cvc={cardCVC}
  focused={cardFocus}
/>

Summary

qrcodejs is a simple, lightweight library for generating QR codes, while react-credit-cards is specifically designed for rendering credit card components in React applications. qrcodejs offers more flexibility in output formats and broader browser support, but lacks credit card-specific features and React integration. react-credit-cards provides a more specialized solution for credit card input and display within React projects, with active maintenance and updates.

Pros of Cleave.js

• More versatile, supporting various input formats beyond credit cards (phone numbers, dates, numerals)
• Lightweight and framework-agnostic, usable with vanilla JavaScript or any front-end framework
• Extensive customization options for input formatting and behavior

Cons of Cleave.js

• Requires more setup and configuration for credit card-specific functionality
• Lacks built-in credit card validation and type detection features
• No out-of-the-box visual representation of credit cards

Code Comparison

Cleave.js:

var cleave = new Cleave('.input-element', {
  creditCard: true,
  onCreditCardTypeChanged: function(type) {
    // Handle card type change
  }
});

React Credit Cards:

<Cards
  number={number}
  name={name}
  expiry={expiry}
  cvc={cvc}
  focused={focused}
/>

Cleave.js provides a more generic approach to input formatting, while React Credit Cards offers a specialized solution for credit card inputs with visual representation. Cleave.js is more flexible but requires additional work for credit card-specific features, whereas React Credit Cards provides a more streamlined experience for credit card inputs out of the box.

Pros of react-interactive-paycard

• More interactive and visually appealing with 3D card flipping animation
• Supports real-time input reflection on the card display
• Includes CVV input and display on card back

Cons of react-interactive-paycard

• Less customizable in terms of card styles and layouts
• Requires more complex setup and configuration
• Larger bundle size due to additional dependencies for animations

Code Comparison

react-interactive-paycard:

<CreditCard
  cardNumber="1234 5678 9012 3456"
  cardHolder="John Doe"
  cardMonth="12"
  cardYear="2023"
  cardCvv="123"
/>

react-credit-cards:

<Cards
  number="1234 5678 9012 3456"
  name="John Doe"
  expiry="12/23"
  cvc="123"
  focused="name"
/>

Both libraries offer similar basic functionality for displaying credit card information. However, react-interactive-paycard provides a more immersive user experience with its 3D animations and real-time input reflection. On the other hand, react-credit-cards offers greater customization options and a simpler implementation.

The code comparison shows that both libraries use similar prop structures, but react-interactive-paycard separates the expiration month and year, while react-credit-cards combines them into a single "expiry" prop. Additionally, react-credit-cards includes a "focused" prop for highlighting specific input fields.
