Feature Comparison: qr.js vs react-qr-code vs jsqr vs qr-image vs qrious

Decoding Capabilities

  • qr.js:

    qr.js supports both QR code generation and decoding, making it versatile for applications that need to handle both tasks. It provides a comprehensive solution for working with QR codes.

  • react-qr-code:

    react-qr-code does not include decoding features; it is primarily for generating QR codes in React applications. For decoding, you would need to integrate another library.

    jsqr excels in decoding QR codes from images and video streams. It is optimized for performance and can handle real-time scanning, making it suitable for applications that require immediate feedback from QR code scanning.

  • qr-image:

    qr-image does not support decoding; it focuses solely on generating QR codes. Therefore, if decoding is a requirement, this library will not meet your needs.

  • qrious:

    qrious does not provide decoding capabilities; it is focused on generating QR codes only. If you need to decode QR codes, you will need to use another library alongside it.

Ease of Use

  • qr.js:

    qr.js offers a user-friendly API for both generating and decoding QR codes. It strikes a good balance between functionality and ease of use, making it suitable for developers of all skill levels.

  • react-qr-code:

    react-qr-code provides a React component that simplifies QR code generation in React applications. Its integration with React makes it easy to use, especially for developers familiar with the React ecosystem.

  • jsqr:

    jsqr has a straightforward API for decoding, but it may require additional setup for capturing video streams. It is lightweight and easy to integrate into existing projects, especially for decoding tasks.

  • qr-image:

    qr-image is simple to use for generating QR codes. Its API is intuitive, allowing developers to quickly create QR codes with minimal configuration, making it ideal for server-side applications.

  • qrious:

    qrious is designed for simplicity, with an easy-to-use API for generating QR codes. It allows developers to quickly render QR codes in the browser without much overhead, making it great for client-side applications.

Customization Options

  • qr.js:

    qr.js provides a range of customization options for both generating and decoding QR codes. Developers can adjust parameters like size, error correction levels, and even add logos to the QR codes, making it versatile for branding purposes.

  • react-qr-code:

    react-qr-code allows for basic customization of QR code size and error correction levels. It is designed to be flexible within the React framework, but does not support advanced styling features.

  • jsqr:

    jsqr offers limited customization options as it focuses on decoding. It does not provide features for customizing the appearance of QR codes, as that is not its primary function.

  • qr-image:

    qr-image allows for some customization in terms of size and error correction levels when generating QR codes. However, it does not support advanced styling options like colors or logos.

  • qrious:

    qrious offers basic customization options such as size and level of error correction. However, it does not support advanced styling features like adding logos or colors to the QR codes.

Integration with Frameworks

  • qr.js:

    qr.js can be used in various frameworks, including React and Angular, as it is a standalone library. It is flexible enough to be integrated into different types of applications.

  • react-qr-code:

    react-qr-code is specifically designed for React applications, providing a seamless integration experience. It allows developers to easily generate QR codes as React components.

  • jsqr:

    jsqr can be integrated into any JavaScript application but does not have specific support for frameworks like React or Angular. It is a standalone library focused on decoding.

  • qr-image:

    qr-image is a server-side library and does not have direct integration with front-end frameworks. It is best used in Node.js environments for generating QR codes.

  • qrious:

    qrious is designed for client-side applications and can be easily integrated into any web project. It works well with frameworks like React, but does not have specific components for them.

Performance

  • qr.js:

    qr.js provides good performance for both generating and decoding QR codes. It balances efficiency with functionality, making it suitable for a wide range of applications.

  • react-qr-code:

    react-qr-code performs well in React applications, providing quick rendering of QR codes. Its performance is generally good, but it may be affected by the overall performance of the React application.

  • jsqr:

    jsqr is optimized for performance in decoding QR codes, especially in real-time scenarios. It is lightweight and efficient, making it suitable for applications that require fast processing of QR codes from video streams.

  • qr-image:

    qr-image performs well for generating QR codes, but its performance is dependent on the server environment. It is efficient for generating QR codes in various formats but does not handle real-time scenarios.

  • qrious:

    qrious is efficient for generating QR codes in the browser, but performance may vary based on the complexity of the QR code and the rendering capabilities of the user's device.

var qr = require('qr.js');

var qrcode = qr('foo bar baz');

var cells = qrcode.modules;

// cell[R] -> row
// if cell[R][C] is true, that cell is "on"
