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

QR Code Generation

  • react-qr-code:

    react-qr-code provides a simple API for generating QR codes in various formats and sizes. It allows customization of the QR code's appearance, including color, error correction level, and the ability to render the QR code as an SVG or canvas element, making it versatile for different design needs.

  • react-qr-reader:

    react-qr-reader does not focus on QR code generation; instead, it is primarily used for reading existing QR codes. It leverages the device's camera to scan QR codes in real-time, providing immediate feedback and data retrieval.

Scanning Capabilities

  • react-qr-code:

    react-qr-code does not offer scanning capabilities, as its primary function is to create QR codes. It is not suitable for applications that require reading QR codes from a camera feed.

  • react-qr-reader:

    react-qr-reader excels in scanning QR codes, providing a robust solution for capturing QR codes using the device's camera. It supports various camera configurations and can handle different lighting conditions, making it reliable for real-time scanning.

Ease of Use

  • react-qr-code:

    react-qr-code is easy to integrate and use within React applications. Its API is straightforward, allowing developers to quickly generate QR codes with minimal setup, making it suitable for projects with tight deadlines.

  • react-qr-reader:

    react-qr-reader also offers a user-friendly API, but it may require additional configuration for camera access and handling permissions. Developers need to manage state changes and error handling for a smooth scanning experience.

Customization Options

  • react-qr-code:

    react-qr-code provides extensive customization options for the generated QR codes, including size, color, and error correction levels. This flexibility allows developers to create visually appealing QR codes that fit their application's design.

  • react-qr-reader:

    react-qr-reader has limited customization options since its focus is on scanning functionality. However, it does allow for some configuration regarding the scanning area and handling of detected QR codes.

Use Cases

  • react-qr-code:

    react-qr-code is ideal for applications that need to display QR codes for sharing links, contact details, or promotional content. It is commonly used in marketing materials, business cards, and websites.

  • react-qr-reader:

    react-qr-reader is best suited for applications that require real-time QR code scanning, such as mobile payment systems, ticketing solutions, and inventory management, where quick data retrieval is essential.

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

    Choose react-qr-code if you need a straightforward solution for generating QR codes without the need for scanning functionality. It is ideal for applications that require static QR codes, such as displaying URLs, contact information, or other text-based data.

  • react-qr-reader:

    Choose react-qr-reader if your application requires real-time QR code scanning capabilities. This package is suitable for use cases where users need to scan QR codes using their device's camera, such as payment systems, event check-ins, or product information retrieval.

react-qr-reader is a React component that allows developers to easily integrate QR code scanning functionality into their applications. It leverages the device's camera to scan QR codes and provides a simple API to handle the scanned data. This package is particularly useful for applications that require quick and efficient QR code scanning, such as mobile apps for payments, ticketing, or information retrieval. The component is designed to be user-friendly and can be easily customized to fit the needs of different applications.

While react-qr-reader is a popular choice for QR code scanning, there are other alternatives in the React ecosystem that offer similar functionalities. Here are a couple of notable options:

  • react-qr-code is a library that allows developers to generate QR codes directly within their React applications. Unlike react-qr-reader, which focuses on scanning QR codes, react-qr-code is centered on creating QR codes from strings or data. This package is ideal for applications that need to generate QR codes for sharing links, contact information, or any other type of data. It provides a straightforward API and customizable options for styling the generated QR codes.
  • react-qr-scanner is another alternative that offers QR code scanning capabilities. It is built on top of the html5-qrcode library and provides a React component for scanning QR codes using the device's camera. react-qr-scanner is designed to be lightweight and efficient, making it suitable for applications that require quick QR code scanning without the overhead of additional features. It also supports both front and back camera scanning, providing flexibility for users.

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>
