            Quagga javascript barcode scanner - Uncaught TypeError: Quagga.init is not a function
            Asked 2021-Jun-12 at 16:55

            I'm trying to write some vanilla javascript code to do barcode scanning from my website, however I can't even get past the first step using the Quagga javascript library. My code is currently this:



            Answered 2021-Jun-12 at 16:55

            Turns out I had to use https://cdnjs.cloudflare.com/ajax/libs/quagga/0.12.1/quagga.min.js instead.

            Using component to read barcodes via CDN
            Asked 2020-Aug-15 at 21:06

            I would like to install in a component via CDN called vue-cc-quaggajs to read barcodes.

            I've tried the following:



            Answered 2020-Aug-15 at 21:06

            I have succeeded with quagga-scanner by building the component with CDN. It works as the default package. Here is the live demo. I worked with this image and it gives me output at console.log.

            Note: Use a good camera to read the barcode. Stackoverflow snippet will not work as you don't get the camera permission from the snippet.

            Install quaggaJS

            You can install using 'npm i quagga' or download it from GitHub, npm.


            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. analyzing static images and 2. using a camera to decode the images from a live-stream. The latter requires the presence of the MediaDevices API. You can track the compatibility of the used Web-APIs for each mode:.
