// Versioning:
// Until the WebCodecs spec is finalized, the major version number is 0. I have chosen to use minor
// version 1 to denote the API as defined by the IDL files from the Chromium repo at
// https://chromium.googlesource.com/chromium/src/+/main/third_party/blink/renderer/modules/webcodecs.
// Please use a version number above 0.1 if using the spec at https://w3c.github.io/webcodecs/ as
// the source.
// The declarations in webcodecs.generated.d.ts have been generated using the code in
// https://github.com/yume-chan/webcodecs-lib-generator. See
// https://github.com/yume-chan/webcodecs-lib-generator/blob/main/README.md for more detail.
/// <reference path="./webcodecs.generated.d.ts" />
// The following declarations are copied from

* A factory function is generated when setting the `MODULARIZE` build option

* By default, the factory function will be named `Module`. It's recommended to
* use the `EXPORT_ES6` option, in which the factory function will be the
* default export. If used without `EXPORT_ES6`, the factory function will be a
* global variable. You can rename the variable using the `EXPORT_NAME` build
* option. It's left to you to declare any global variables as needed in your
* application's types.

# barcode-detector
[![npm](https://img.shields.io/npm/v/barcode-detector)](https://www.npmjs.com/package/barcode-detector/v/latest) [![npm bundle size (scoped)](https://img.shields.io/bundlephobia/minzip/barcode-detector)](https://www.npmjs.com/package/barcode-detector/v/latest) [![jsDelivr hits (npm scoped)](https://img.shields.io/jsdelivr/npm/hm/barcode-detector?color=%23ff5627)](https://cdn.jsdelivr.net/npm/barcode-detector@latest/)
A [Barcode Detection API](https://wicg.github.io/shape-detection-api/#barcode-detection-api) polyfill that uses [ZXing-C++ WebAssembly](https://github.com/Sec-ant/zxing-wasm) under the hood.
Supported barcode formats: `aztec`, `code_128`, `code_39`, `code_93`, `codabar`, `databar`, `databar_expanded`, `data_matrix`, `dx_film_edge`, `ean_13`, `ean_8`, `itf`, `maxi_code` (only generated ones, and no position info), `micro_qr_code`, `pdf417`, `qr_code`, `rm_qr_code`, `upc_a`, `upc_e`, `linear_codes` and `matrix_codes` (for convenience).
## Install
To install, run the following command:
```bash
npm i barcode-detector
```
## Recommended Usage with Node + ESM
This package can be imported in three different ways:
### Pure Module
```ts
import { BarcodeDetector } from "barcode-detector/pure";
```
To avoid potential namespace collisions, you can also rename the export:
```ts
import { BarcodeDetector as BarcodeDetectorPolyfill } from "barcode-detector/pure";
```
This approach is beneficial when you want to use a package to detect barcodes without polluting `globalThis`, or when your runtime already provides an implementation of the Barcode Detection API, but you still want this package to function.
### Side Effects
```ts
import "barcode-detector/side-effects";
```
This approach is beneficial when you need a drop-in polyfill. If there's already an implementation of Barcode Detection API on `globalThis`, this won't take effect (type declarations will, as we cannot optionally declare types). In such cases, please use the [pure module](#pure-module) instead.
### Both
```ts
import { BarcodeDetector } from "barcode-detector";
```
This approach combines the [pure module](#pure-module) and [side effects](#side-effects).
## Recommended Usage in Modern Browsers
For [modern browsers that support ES modules](https://caniuse.com/es6-module), this package can be imported via the `<script type="module">` tags:
1. Include side effects:
```html
<!-- register -->
<script
type="module"
src="https://fastly.jsdelivr.net/npm/barcode-detector@2/dist/es/side-effects.min.js"
></script>
<!-- use -->
<script type="module">
const barcodeDetector = new BarcodeDetector();
</script>
```
2. Script scoped access:
```html
<script type="module">
import { BarcodeDetector } from "https://fastly.jsdelivr.net/npm/barcode-detector@2/dist/es/pure.min.js";
const barcodeDetector = new BarcodeDetector();
</script>
```
3. With import maps:
```html
<!-- import map -->
<script type="importmap">
{
"imports": {
"barcode-detector/pure": "https://fastly.jsdelivr.net/npm/barcode-detector@2/dist/es/pure.min.js"
}
}
</script>
<!-- script scoped access -->
<script type="module">
import { BarcodeDetector } from "barcode-detector/pure";
const barcodeDetector = new BarcodeDetector();
</script>
```
## Usage with Legacy Compatibility
Starting from v1.2, this package supports IIFE and CJS build outputs for use cases that require legacy compatibility.
### IIFE
For legacy browsers that lack support for module type `<script>` tags, or for userscripts, IIFE is the preferred choice. Upon executing the IIFE script, a variable named `BarcodeDetectionAPI` will be registered in the global.
```html
<!--
IIFE pure.js registers:
window.BarcodeDetectionAPI.BarcodeDetector
window.BarcodeDetectionAPI.setZXingModuleOverrides
-->
<script src="https://fastly.jsdelivr.net/npm/barcode-detector@2/dist/iife/pure.min.js"></script>
<!--
IIFE side-effects.js registers:
window.BarcodeDetector
window.BarcodeDetectionAPI.setZXingModuleOverrides
-->
<script src="https://fastly.jsdelivr.net/npm/barcode-detector@2/dist/iife/side-effects.min.js"></script>
<!--
IIFE index.js registers:
window.BarcodeDetector
window.BarcodeDetectionAPI.BarcodeDetector
window.BarcodeDetectionAPI.setZXingModuleOverrides
-->
<script src="https://fastly.jsdelivr.net/npm/barcode-detector@2/dist/iife/index.min.js"></script>
```
### CJS
This package can also be consumed as a commonjs package:
1. Vanilla Javascript:
```js
// src/index.js
const { BarcodeDetector } = require("barcode-detector/pure");
```
2. With Typescript:
```ts
// src/index.ts
import { BarcodeDetector } from "barcode-detector/pure";
```
`tsconfig.json`:
```json
{
"compilerOptions": {
"module": "CommonJS",
"moduleResolution": "Node",
"skipLibCheck": true
},
"include": ["src"]
}
```
## `setZXingModuleOverrides`
In addition to `BarcodeDetector`, this package exports another function called `setZXingModuleOverrides`.
This package employs [zxing-wasm](https://github.com/Sec-ant/zxing-wasm) to enable the core barcode reading functionality. As a result, a `.wasm` binary file is fetched at runtime. The default fetch path for this binary file is:
```
https://fastly.jsdelivr.net/npm/zxing-wasm@<version>/dist/reader/zxing_reader.wasm
```
The `setZXingModuleOverrides` function allows you to govern where the `.wasm` binary is served from, thereby enabling offline use of the package, use within a local network, or within a site having strict [CSP](https://developer.mozilla.org/docs/Web/HTTP/CSP) rules.
For instance, should you want to inline this `.wasm` file in your build output for offline usage, with the assistance of build tools, you could try:
```ts
// src/index.ts
import wasmFile from "../node_modules/zxing-wasm/dist/reader/zxing_reader.wasm?url";
import {
setZXingModuleOverrides,
BarcodeDetector,
} from "barcode-detector/pure";
setZXingModuleOverrides({
locateFile: (path, prefix) => {
if (path.endsWith(".wasm")) {
return wasmFile;
}
return prefix + path;
},
});
const barcodeDetector = new BarcodeDetector();
// detect barcodes
// ...
```
Alternatively, the `.wasm` file could be copied to your dist folder to be served from your local server, without incorporating it into the output as an extensive base64 data URL.
It's noteworthy that you'll always want to choose the correct version of the `.wasm` file, so the APIs exported by it are exactly what the js code expects.
For more information on how to use this function, you can check [the notes here](https://github.com/Sec-ant/zxing-wasm#notes) and [discussions here](https://github.com/Sec-ant/barcode-detector/issues/18) and [here](https://github.com/gruhn/vue-qrcode-reader/issues/354).
This function is exported from all the subpaths, including the [side effects](#side-effects).
## API
Please check the [spec](https://wicg.github.io/shape-detection-api/#barcode-detection-api), [MDN doc](https://developer.mozilla.org/docs/Web/API/Barcode_Detection_API) and [Chromium implementation](https://github.com/chromium/chromium/tree/main/third_party/blink/renderer/modules/shapedetection) for more information.
## Lifecycle Events
The `BarcodeDetector` provided by this package also extends class `EventTarget` and provides 2 lifecycle events: `load` and `error`. You can use `addEventListener` and `removeEventListener` to register and remove callback hooks on these events.
### `load` Event
The `load` event, which is a `CustomEvent`, will be dispatched on the successful instantiation of ZXing wasm module. For advanced usage, the instantiated module is passed as the `detail` parameter.
```ts
import { BarcodeDetector } from "barcode-detector/pure";
const barcodeDetector = new BarcodeDetector();
barcodeDetector.addEventListener("load", ({ detail }) => {
console.log(detail); // zxing wasm module
});
```
### `error` Event
The `error` event, which is a `CustomEvent`, will be dispatched if the instantiation of ZXing wasm module is failed. An error is passed as the `detail` parameter.
```ts
import { BarcodeDetector } from "barcode-detector/pure";
const barcodeDetector = new BarcodeDetector();
barcodeDetector.addEventListener("error", ({ detail }) => {
console.log(detail); // an error
});
```
## Example
```ts
import { BarcodeDetector } from "barcode-detector/pure";
const barcodeDetector: BarcodeDetector = new BarcodeDetector({
formats: ["qr_code"],
});
const imageFile = await fetch(

</p>
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
<qrcode-stream @detect="onDetect"></qrcode-stream>
```
```js
methods: {
onDetect (detectedCodes) {
// ...
}
}
```

* [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
<script src="./vue.js"></script>
<script src="./vue-qrcode-reader.umd.js"></script>
```
All components are automatically registered globally.
Use kebab-case to reference them in your templates:
```html
<qrcode-stream></qrcode-stream>
<qrcode-drop-zone></qrcode-drop-zone>
<qrcode-capture></qrcode-capture>
```
# 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 `<version>`. Run `npm version <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.
