+
+A set of Vue.js components for detecting QR codes and [various other barcode formats](https://github.com/Sec-ant/barcode-detector?tab=readme-ov-file#barcode-detector) right in the browser:
+
+- :movie_camera: `QrcodeStream` continuously scans frames from a camera stream.
+- :put_litter_in_its_place: `QrcodeDropZone` is an empty region where you can drag-and-drop images to be decoded.
+- :open_file_folder: `QrcodeCapture` is a classic file upload field, instantly scanning all files you select.
+
+All components are responsive.
+Beyond that, close to zero styling.
+Make them fit your layout.
+Usage is simple and straight forward:
+
+```html
+
+```
+
+```js
+methods: {
+ onDetect (detectedCodes) {
+ // ...
+ }
+}
+```
+
+### Preview
+
+
+ 
+ 
+
+
+### Related Projects
+
+* [Barcode Detector Polyfill](https://github.com/Sec-ant/barcode-detector)
+* [Svelte Port](https://github.com/ollema/svelte-qrcode-reader)
+
+# Installation :package:
+
+## With NPM
+
+Run
+
+```bash
+npm install vue-qrcode-reader
+```
+
+You can import the components independantly
+
+```javascript
+import { QrcodeStream, QrcodeDropZone, QrcodeCapture } from 'vue-qrcode-reader'
+
+const MyComponent = {
+ //
+ components: {
+ QrcodeStream,
+ QrcodeDropZone,
+ QrcodeCapture
+ }
+
+ // ...
+}
+```
+
+or register all of them globally right away
+
+```javascript
+import Vue from 'vue'
+import VueQrcodeReader from 'vue-qrcode-reader'
+
+Vue.use(VueQrcodeReader)
+```
+
+## Without NPM
+
+Include the following JS file:
+
+https://unpkg.com/vue-qrcode-reader/dist/vue-qrcode-reader.umd.js
+
+Make sure to include it after Vue:
+
+```html
+
+
+```
+
+All components are automatically registered globally.
+Use kebab-case to reference them in your templates:
+
+```html
+
+
+
+```
+
+# Troubleshooting :zap:
+
+#### I don't see the camera when using `QrcodeStream`.
+
+- Check if it works on the demo page. Especially the [Handle Errors](https://gruhn.github.io/vue-qrcode-reader/demos/HandleErrors.html) demo,
+ since it renders error messages.
+ - The demo works but it doesn't work in my project: Listen for the `error` event to investigate errors.
+ - The demo doesn't work: Carefully review the Browser Support section above.
+ Maybe your device is just not supported.
+
+#### I'm running a dev server on localhost. How to test on my mobile device without HTTPS?
+
+- If your setup is Desktop Chrome + Android Chrome, use [Remote Debugging](https://developers.google.com/web/tools/chrome-devtools/remote-debugging/) which allows your Android device to [access your local server as localhost](https://developers.google.com/web/tools/chrome-devtools/remote-debugging/local-server).
+- Otherwise use a reverse proxy like [ngrok](https://ngrok.com/) or [serveo](https://serveo.net/) to temporarily make your local server publicly available with HTTPS.
+- There are also loads of serverless/static hosting services that have HTTPS enabled by default and where you can deploy your web app for free (e.g. _GitHub Pages_, _GitLab Pages_, _Google Firebase_, _Netlify_, _Heroku_, _ZEIT Now_, ...)
+
+#### Some of my QR codes are not being detected.
+
+- Make sure, there is some white border around the QR code.
+- Test your QR codes in the upstream packages: [`barcode-detector`](https://github.com/Sec-ant/barcode-detector) -> [`zxing-wasm`](https://github.com/Sec-ant/zxing-wasm) -> [`zxing-cpp`](https://github.com/zxing-cpp/zxing-cpp), and file detection issues in the highest-level repository where the problem first occurs.
+
+#### 1D barcodes are not being detected.
+
+The default value for the `formats` prop is `"['qr_code']"`, which reflects the setting before the `formats` prop was available.
+You'll need to add [other barcode formats](https://github.com/Sec-ant/barcode-detector?tab=readme-ov-file#barcode-detector) to this prop to detect those types of barcodes.
+Check out [this demo](https://gruhn.github.io/vue-qrcode-reader/demos/FullDemo.html).
+
+#### How to make it work with Vue 2?
+
+Support is dropped but you can downgrade to vue-qrcode-reader v3.\* or lower.
+
+#### I get a "Failed to fetch" error at runtime for some Wasm file.
+
+That Wasm file implements the QR code detector.
+Unfortunately, it's not very convenient to bundle this file with the package.
+So by default we fetch it at runtime from a CDN.
+That's an issue for offline applications or applications that run in a network with strict CSP policy.
+For a workaround see: https://github.com/gruhn/vue-qrcode-reader/issues/354
+
+#### `torch` is not supported on my device, although it has a flashlight.
+
+Support for `torch` is inconsistent across devices, cameras and browsers and operating systems.
+On some devices the rear camera supports `torch` but the front camera doesn't,
+even if the front camera actually has a flashlight.
+
+Furthermore, `torch` is not supported on iOS at all (last checked iOS 17.1).
+
+Visit [this page](https://gruhn.github.io/vue-qrcode-reader/select-camera-demo.html) with your device.
+The list of links represents all cameras installed on the device.
+If you click, the camera should be loaded.
+Below the camera view the JSON object of "capabilities" is printed.
+If it doesn't contain the key/value pair `"torch": true` then flashlight is not supported for that camera.
+
+This JSON object provided as payload of the [`camera-on` event](https://gruhn.github.io/vue-qrcode-reader/api/QrcodeStream.html#camera-on).

+# WebRTC adapter #
+adapter.js is a shim to insulate apps from spec changes and prefix differences in WebRTC. The prefix differences are mostly gone these days but differences in behaviour between browsers remain.
+
+This repository used to be part of the WebRTC organisation on github but moved. We aim to keep the old repository updated with new releases.
+
+## Install ##
+
+#### NPM
+```bash
+npm install webrtc-adapter
+```
+
+#### Bower
+```bash
+bower install webrtc-adapter
+```
+
+## Usage ##
+##### Javascript
+Just import adapter:
+```
+import adapter from 'webrtc-adapter';
+```
+No further action is required. You might want to use adapters browser detection
+which detects which webrtc quirks are required. You can look at
+```
+adapter.browserDetails.browser
+```
+for webrtc engine detection (which will for example detect Opera or the Chromium based Edge as 'chrome') and
+```
+adapter.browserDetails.version
+```
+for the version according to the user-agent string.
+
+##### NPM
+Copy to desired location in your src tree or use a minify/vulcanize tool (node_modules is usually not published with the code).
+See [webrtc/samples repo](https://github.com/webrtc/samples) as an example on how you can do this.
+
+#### Prebuilt releases
+##### Web
+In the [gh-pages branch](https://github.com/webrtcHacks/adapter/tree/gh-pages) prebuilt ready to use files can be downloaded/linked directly.
+Latest version can be found at https://webrtc.github.io/adapter/adapter-latest.js.
+Specific versions can be found at https://webrtc.github.io/adapter/adapter-N.N.N.js, e.g. https://webrtc.github.io/adapter/adapter-1.0.2.js.
+
+##### Bower
+You will find `adapter.js` in `bower_components/webrtc-adapter/`.
+
+##### NPM
+In node_modules/webrtc-adapter/out/ folder you will find 4 files:
+* `adapter.js` - includes all the shims and is visible in the browser under the global `adapter` object (window.adapter).
+* `adapter_no_global.js` - same as `adapter.js` but is not exposed/visible in the browser (you cannot call/interact with the shims in the browser).
+
+Include the file that suits your need in your project.
+
+## Development ##
+Head over to [test/README.md](https://github.com/webrtcHacks/adapter/blob/master/test/README.md) and get started developing.
+
+## Publish a new version ##
+* Go to the adapter repository root directory
+* Make sure your repository is clean, i.e. no untracked files etc. Also check that you are on the master branch and have pulled the latest changes.
+* Depending on the impact of the release, either use `patch`, `minor` or `major` in place of ``. Run `npm version -m 'bump to %s'` and type in your password lots of times (setting up credential caching is probably a good idea).
+* Create and merge the PR if green in the GitHub web ui
+* Go to the releases tab in the GitHub web ui and edit the tag.
+* Add a summary of the recent commits in the tag summary and a link to the diff between the previous and current version in the description, [example](https://github.com/webrtcHacks/adapter/releases/tag/v3.4.1).
+* Go back to your checkout and run `git pull`
+* Run `npm publish` (you need access to the [webrtc-adapter npmjs package](https://www.npmjs.com/package/webrtc-adapter)). For big changes, consider using a [tag version](https://docs.npmjs.com/adding-dist-tags-to-packages) such as `next` and then [change the dist-tag after testing](https://docs.npmjs.com/cli/dist-tag).
+* Done! There should now be a new release published to NPM and the gh-pages branch.
+
+Note: Currently only tested on Linux, not sure about Mac but will definitely not work on Windows.
+
+### Publish a hotfix patch versions
+In some cases it may be necessary to do a patch version while there are significant changes changes on the master branch.
+To make a patch release,
+* checkout the latest git tag using `git checkout tags/vMajor.minor.patch`.
+* checkout a new branch, using a name such as patchrelease-major-minor-patch.
+* cherry-pick the fixes using `git cherry-pick some-commit-hash`.
+* run `npm version patch`. This will create a new patch version and publish it on github.
+* check out `origin/bumpVersion` branch and publish the new version using `npm publish`.
+* the branch can now safely be deleted. It is not necessary to merge it into the main branch since it only contains cherry-picked commits.

+[ZXing-C++](https://github.com/zxing-cpp/zxing-cpp) WebAssembly as an ES/CJS module with types. Read or write barcodes in your browser (or other JS runtimes like node)!
+
+Visit [this online demo](https://zxing-wasm-demo.netlify.app/) to quickly explore its basic functions. It works best on the latest chromium browsers.
+

+
+## Usage
+
+This package exports 3 subpaths: `full`, `reader` and `writer`. You can choose whichever fits your needs. If you use TypeScript, you should set [`moduleResolution`](https://www.typescriptlang.org/docs/handbook/modules/theory.html#module-resolution) to [`bundler`](https://www.typescriptlang.org/docs/handbook/modules/reference.html#bundler), [`node16` or `nodenext`](https://www.typescriptlang.org/docs/handbook/modules/reference.html#node16-nodenext-1) in your `tsconfig.json` file to properly resolve the exported module.
+
+### `zxing-wasm` or `zxing-wasm/full`
+
+These 2 subpaths include functions to both read and write barcodes. The wasm binary size is ~1.17 MB.
+
+```ts
+import {
+ readBarcodesFromImageFile,
+ readBarcodesFromImageData,
+ writeBarcodeToImageFile,
+} from "zxing-wasm";
+```
+
+or
+
+```ts
+import {
+ readBarcodesFromImageFile,
+ readBarcodesFromImageData,
+ writeBarcodeToImageFile,
+} from "zxing-wasm/full";
+```
+
+### `zxing-wasm/reader`
+
+This subpath only includes functions to read barcodes. The wasm binary size is ~930 KB.
+
+```ts
+import {
+ readBarcodesFromImageFile,
+ readBarcodesFromImageData,
+} from "zxing-wasm/reader";
+```
+
+### `zxing-wasm/writer`
+
+This subpath only includes a function to write barcodes. The wasm binary size is ~330 KB.
+
+```ts
+import { writeBarcodeToImageFile } from "zxing-wasm/writer";
+```
+
+### IIFE Scripts
+
+Apart from ES and CJS modules, this package also ships IIFE scripts. The registered global variable is named `ZXingWASM`.
+
+```html
+
+
+
+
+
+
+
+
+```
+
+### [`readBarcodesFromImageFile`](https://zxing-wasm.netlify.app/functions/full.readBarcodesFromImageFile.html) and [`readBarcodesFromImageData`](https://zxing-wasm.netlify.app/functions/full.readBarcodesFromImageData.html)
+
+These 2 functions are for reading barcodes.
+
+[`readBarcodesFromImageFile`](https://zxing-wasm.netlify.app/functions/full.readBarcodesFromImageFile.html) accepts an image [`Blob`](https://developer.mozilla.org/docs/Web/API/Blob) or an image [`File`](https://developer.mozilla.org/docs/Web/API/File) as the first input. They're encoded images, e.g. `.png` `.jpg` files.
+
+[`readBarcodesFromImageData`](https://zxing-wasm.netlify.app/functions/full.readBarcodesFromImageData.html) accepts an [`ImageData`](https://developer.mozilla.org/docs/Web/API/ImageData) as the first input. They're raw pixels that usually acquired from [`
