Question feed. Stack Overflow works best with JavaScript enabled.In this tutorial I am going to demonstrate, how to add barcode scanner functionality to an HTML form built with Bootstrap - thus, enabling the user to scan a barcode with the smartphone camera or webcam.

In previous articles, I introduced multiple ways to scan barcodes from an HTML-based web app: using JavaScript librariesusing third-party mobile apps and using bluetooth barcode scanners. Which possibility to choose, strongly depends on the specifics of your project. In many cases, however, scanning a barcode is merely supposed to save the user from typing a long number into an input field.

But you can still use the code in your SSL-enabled project. To try out the camera on Chrome and Opera, please refer to the official demos for now. They have much more complicated and flexible code, but work just the same in the end. In general, the trouble with camera access through JavaScript is, that the results strongly depend on the browser, the operating system and even the device hardware.

So I've also added an extra button for a fallback to the better supported File API, which allows the user to call the native camera app on mobile devices or the regular browser upload on desktops.

Try it out on different devices and browsers to see what happens. For more details on differences between the APIs refer to this post. The whole idea of scanning barcodes with a built-in camera, of course, makes most sense on mobile devices. However, the quality of the camera stream and many important features like autofocus or brightness adjustment seem very device-dependent. But cheaper devices often have problems focusing when using the live stream.

At the same time it's no problem when taking the same picture via native camera app. For example, the autofocus of the camera only on Chrome and Opera. Firefox is less picky, but, for some reason, it provieds a very dark and blurred picture, so the recognition only works from time to time.

I guess, Chrome is the best choince for now, but it still depends on the device too. Now, let's see how this works. First of all, you need to include QuaggaJS on your page: just follow the official installation instructions.

Now simply copy-paste the code below to get it working. Read the comments in the demo code for more information.Windows and Linux editions. JavaScript editions for web.

This is not yet another port of the great zxing library, but more of an extension to it. This implementation features a barcode locator which is capable of finding a barcode-like pattern in an image resulting in an estimated bounding box including the rotation. Simply speaking, this reader is invariant to scale and rotation, whereas other libraries require the barcode to be aligned with the viewport.

Quagga makes use of many modern Web-APIs which are not implemented by all browsers yet. There are two modes in which Quagga operates: 1.

You can track the compatibility of the used Web-APIs for each mode:. QuaggaJS can be installed using npmboweror by including it with the script tag.

Currently, the full functionality is only available through the browser. When using QuaggaJS within nodeonly file-based decoding is available. The script exposes the library on the global namespace under Quagga.

For starters, have a look at the examples to get an idea where to go from here. This npm script builds a non optimized version quagga. Additionally, a quagga. This file is only valid for the non-uglified version quagga. For the use in node, the build command also creates a quagga.

You can check out the examples to get an idea of how to use QuaggaJS. Basically the library exposes the following API:. This method initializes the library for a given configuration config see below and invokes the callback err when Quagga has finished its bootstrapping phase.

The initialization process also requests for camera access if real-time detection is configured. In case of an error, the err parameter is set and contains information about the cause. A potential cause may be the inputStream. When the library is initialized, the start method starts the video-stream and begins locating and decoding the images. If the decoder is currently running, after calling stop the decoder does not process any more images.

Additionally, if a camera-stream was requested upon initialization, this operation also disconnects the camera. This method registers a callback data function that is called for each frame after the processing is done.

Registers a callback data function which is triggered whenever a barcode- pattern has been located and decoded successfully. The passed data object contains information about the decoding process including the detected code which can be obtained by calling data. In contrast to the calls described above, this method does not rely on getUserMedia and operates on a single image instead.

The provided callback is the same as in onDetected and contains the result data object.
