To enforce the use of the new api with detailed scan results, call the constructor with an options object, see below. Create HTMLĬreate a element where the web cam video stream should get rendered: Especially if you want to scan from the device's camera, camera support by the browser is the stricter restriction. You will likely not need to use the legacy build though, as general browser support is already very good for the regular build. Note, that the legacy build is larger as it includes some polyfills and, to support browsers that don't support dynamic imports, inlines the worker script which however would be needed to be loaded in legacy browsers anyway. It's a UMD build and can be used as a replacement for, see above. If you need to support old browsers, you can use, which is ECMAScript 2015 (ES6) compatible.
