Feature Comparison: react-qr-code vs react-qr-reader vs react-qr-scanner

QR Code Generation

  • react-qr-code:

    react-qr-code allows developers to generate QR codes effortlessly with customizable options such as size, color, and error correction levels. It is designed for simplicity, making it easy to integrate into any React component without complex configurations.

  • react-qr-reader:

    react-qr-reader does not focus on QR code generation but rather on reading and interpreting QR codes. Therefore, it does not provide generation features, making it less suitable if you need to create QR codes.

  • react-qr-scanner:

    react-qr-scanner is primarily focused on scanning QR codes, but it can also be used in conjunction with other libraries to generate QR codes. It excels in providing a seamless user experience for scanning.

Scanning Capabilities

  • react-qr-code:

    react-qr-code does not include scanning capabilities, as its main function is to generate QR codes. It is not suitable for applications requiring QR code scanning.

  • react-qr-reader:

    react-qr-reader offers robust scanning capabilities, supporting both camera and file input for scanning QR codes. It provides a simple API that makes it easy to implement scanning features in your application.

  • react-qr-scanner:

    react-qr-scanner provides advanced scanning capabilities with real-time scanning and camera access. It is optimized for mobile devices and can handle various QR code formats, making it ideal for applications that require quick and efficient scanning.

Ease of Use

  • react-qr-code:

    react-qr-code is very easy to use, with a straightforward API that allows developers to generate QR codes with minimal setup. It is perfect for developers looking for a quick solution without extensive configuration.

  • react-qr-reader:

    react-qr-reader is also user-friendly, with clear documentation and examples that help developers implement QR code scanning quickly. Its simple interface makes it accessible for developers of all skill levels.

  • react-qr-scanner:

    react-qr-scanner has a slightly steeper learning curve due to its advanced features, but it is still manageable for developers familiar with React. The documentation provides guidance on implementing its more complex functionalities.

Performance

  • react-qr-code:

    react-qr-code is lightweight and performs well for generating QR codes without significant overhead, making it suitable for applications where performance is critical.

  • react-qr-reader:

    react-qr-reader is optimized for performance, providing quick scanning capabilities with minimal lag. It efficiently handles camera input and can process QR codes rapidly, ensuring a smooth user experience.

  • react-qr-scanner:

    react-qr-scanner is designed for high performance in scanning scenarios, utilizing WebRTC for real-time camera access. It is optimized for mobile devices, ensuring quick and efficient scanning even in challenging conditions.

Customization Options

  • react-qr-code:

    react-qr-code offers extensive customization options for the generated QR codes, allowing developers to modify colors, sizes, and error correction levels to match their application's design.

  • react-qr-reader:

    react-qr-reader provides limited customization options, focusing primarily on the scanning process rather than QR code appearance. It is more about functionality than design.

  • react-qr-scanner:

    react-qr-scanner allows some customization of the scanning interface but is primarily focused on functionality. Developers can adjust settings related to scanning behavior but have fewer options for visual customization.

How to Choose: react-qr-code vs react-qr-reader vs react-qr-scanner
  • react-qr-code:

    Choose react-qr-code if your primary need is to generate QR codes easily and customize their appearance. It is lightweight and straightforward, ideal for applications that require quick QR code generation without additional scanning features.

  • react-qr-reader:

    Select react-qr-reader if you need a robust solution for scanning QR codes with a simple interface. It is suitable for applications where scanning QR codes is a primary function, providing a reliable and responsive scanning experience across devices.

  • react-qr-scanner:

    Opt for react-qr-scanner if you require a more advanced scanning solution that includes features like camera access and real-time scanning capabilities. This library is ideal for applications that need to scan QR codes quickly and efficiently, especially in mobile environments.

Android & iOS

Installation

npm i react-qr-code

When using this library with React Native, you will also need to have react-native-svg installed.

npm i react-native-svg
cd ios && pod install

The Gist

import React from "react";
import ReactDOM from "react-dom";
import QRCode from "react-qr-code";

ReactDOM.render(<QRCode value="hey" />, document.getElementById("Container"));

Note: If the QR code is likely to appear next to dark objects, you will need to wrap it in a light-colored container to preserve the 'quiet zone', e.g.

<div style={{ background: 'white', padding: '16px' }}>
  <QRCode ... />
</div>

Responsive QR code example:

// Can be anything instead of `maxWidth` that limits the width.
<div style={{ height: "auto", margin: "0 auto", maxWidth: 64, width: "100%" }}>
  <QRCode
    size={256}
    style={{ height: "auto", maxWidth: "100%", width: "100%" }}
    value={value}
    viewBox={`0 0 256 256`}
  />
</div>
