ZXing

Project in Maintenance Mode Only

The project is in maintenance mode, meaning, changes are driven by contributed patches. Only bug fixes and minor enhancements will be considered. The Barcode Scanner app can no longer be published, so it's unlikely any changes will be accepted for it. There is otherwise no active development or roadmap for this project. It is "DIY".

Runs on your favorite ECMAScript ecosystem

If it doesn't, we gonna make it.

What is ZXing?

ZXing ("zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java, with ports to other languages.

Supported Formats

Attention

NOTE: While we do not have the time to actively maintain zxing-js anymore, we are open to new maintainers taking the lead.

Demo

See Live Preview in browser.

Note: All the examples are using ES6, be sure is supported in your browser or modify as needed, Chrome recommended.

Installation

npm i @zxing/library --save

or

yarn add @zxing/library

Limitations

On iOS-Devices with iOS < 14.3 camera access works only in native Safari and not in other Browsers (Chrome,...) or Apps that use an UIWebView or WKWebView. This is not a restriction of this library but of the limited WebRTC support by Apple. The behavior might change in iOS 11.3 (Apr 2018?, not tested) as stated here

iOS 14.3 (released in december 2020) now supports WebRTC in 3rd party browsers as well 🎉

Browser Support

The browser layer is using the MediaDevices web API which is not supported by older browsers.

You can use external polyfills like WebRTC adapter to increase browser compatibility.

Also, note that the library is using the TypedArray (Int32Array, Uint8ClampedArray, etc.) which are not available in older browsers (e.g. Android 4 default browser).

You can use core-js to add support to these browsers.

In the PDF 417 decoder recent addition, the library now makes use of the new BigInt type, which is not supported by all browsers as well. There's no way to polyfill that and ponyfill libraries are way to big, but even if PDF 417 decoding relies on BigInt the rest of the library shall work ok in browsers that doesn't support it.

There's no polyfills for BigInt in the way it's coded in here.

Usage

Also, note that the library is using the TypedArray (Int32Array, Uint8ClampedArray, etc.) which are not available in older browsers (e.g. Android 4 default browser).
You can use core-js to add support to these browsers.
In the PDF 417 decoder recent addition, the library now makes use of the new BigInt type, which is not supported by all browsers as well. There's no way to polyfill that and ponyfill libraries are way to big, but even if PDF 417 decoding relies on BigInt the rest of the library shall work ok in browsers that doesn't support it.
There's no polyfills for BigInt in the way it's coded in here.

Special thanks to all the contributors who have contributed for this project. We heartly thankful to you all.
And a special thanks to @aleris who created the project itself and made available the initial QR code port.

ZXing
Project in Maintenance Mode Only
The project is in maintenance mode, meaning, changes are driven by contributed patches.
Only bug fixes and minor enhancements will be considered. The Barcode Scanner app can
no longer be published, so it's unlikely any changes will be accepted for it.
There is otherwise no active development or roadmap for this project. It is "DIY".
Runs on your favorite ECMAScript ecosystem
If it doesn't, we gonna make it.
What is ZXing?
ZXing ("zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java, with ports to other languages.
Supported Formats
See Projects and Milestones for what is currently done and what's planned next. 👀

Attention
NOTE: While we do not have the time to actively maintain zxing-js anymore, we are open to new maintainers taking the lead.
Demo
See Live Preview in browser.
Note: All the examples are using ES6, be sure is supported in your browser or modify as needed, Chrome recommended.
Installation
npm i @zxing/library --save
or
yarn add @zxing/library
Limitations
On iOS-Devices with iOS < 14.3 camera access works only in native Safari and not in other Browsers (Chrome,...) or Apps that use an UIWebView or WKWebView. This is not a restriction of this library but of the limited WebRTC support by Apple. The behavior might change in iOS 11.3 (Apr 2018?, not tested) as stated here
iOS 14.3 (released in december 2020) now supports WebRTC in 3rd party browsers as well 🎉
Browser Support
The browser layer is using the MediaDevices web API which is not supported by older browsers.
You can use external polyfills like WebRTC adapter to increase browser compatibility.
Also, note that the library is using the TypedArray (Int32Array, Uint8ClampedArray, etc.) which are not available in older browsers (e.g. Android 4 default browser).
