+# Html5-QRCode
+
+## Lightweight & cross platform QR Code and Bar code scanning library for the web
+
+Use this lightweight library to easily / quickly integrate QR code, bar code, and other common code scanning capabilities to your web application.
+
+## Key highlights
+- 🔲 Support scanning [different types of bar codes and QR codes](#supported-code-formats).
+
+- 🖥 Supports [different platforms](#supported-platforms) be it Android, IOS, MacOs, Windows or Linux
+
+- 🌠Supports [different browsers](#supported-platforms) like Chrome, Firefox, Safari, Edge, Opera ...
+
+- 📷 Supports scanning with camera as well as local files
+
+- âž¡ï¸ Comes with an [end to end library with UI](#easy-mode---with-end-to-end-scanner-user-interface) as well as a [low level library to build your own UI with](#pro-mode---if-you-want-to-implement-your-own-user-interface).
+
+- 🔦 Supports customisations like [flash/torch support](#showtorchbuttonifsupported---boolean--undefined), zooming etc.
+
+
+Supports two kinds of APIs
+
+- `Html5QrcodeScanner` — End-to-end scanner with UI, integrate with less than ten lines of code.
+
+- `Html5Qrcode` — Powerful set of APIs you can use to build your UI without worrying about camera setup, handling permissions, reading codes, etc.
+
+> Support for scanning local files on the device is a new addition and helpful for the web browser which does not support inline web-camera access in smartphones. **Note:** This doesn't upload files to any server — everything is done locally.

+>
+> Before version 15.1, Webkit for IOS is used by Chrome, Firefox, and other browsers in IOS and they do not have webcam permissions yet. There is an ongoing issue on fixing the support for iOS - [issue/14](https://github.com/mebjas/html5-qrcode/issues/14)
+
+### Framework support
+The library can be easily used with several other frameworks, I have been adding examples for a few of them and would continue to add more.

+## Description - [View Demo](https://blog.minhazav.dev/research/html5-qrcode.html)
+
+> See an end to end scanner experience at [scanapp.org](https://scanapp.org).
+
+This is a cross-platform JavaScript library to integrate QR code, bar codes & a few other types of code scanning capabilities to your applications running on HTML5 compatible browser.
+
+Supports:
+- Querying camera on the device (with user permissions)
+- Rendering live camera feed, with easy to use user interface for scanning
+- Supports scanning a different kind of QR codes, bar codes and other formats
+- Supports selecting image files from the device for scanning codes
+
+## How to use

+
+### Extra optional `configuration` in `start()` method
+Configuration object that can be used to configure both the scanning behavior and the user interface (UI). Most of the fields have default properties that will be used unless a different value is provided. If you do not want to override anything, you can just pass in an empty object `{}`.
+
+#### `fps` — Integer, Example = 10
+A.K.A frame per second, the default value for this is 2, but it can be increased to get faster scanning. Increasing too high value could affect performance. Value `>1000` will simply fail.
+
+#### `qrbox` — `QrDimensions` or `QrDimensionFunction` (Optional), Example = `{ width: 250, height: 250 }`
+Use this property to limit the region of the viewfinder you want to use for scanning. The rest of the viewfinder would be shaded. For example, by passing config `{ qrbox : { width: 250, height: 250 } }`, the screen will look like:
+
+<img src="https://scanapp.org/assets/github_assets/screen.gif" />
+
+This can be used to set a rectangular scanning area with config like:
+
+```js
+let config = { qrbox : { width: 400, height: 150 } }
+```
+
+This config also accepts a function of type
+```ts
+/**
+ * A function that takes in the width and height of the video stream
+* and returns QrDimensions.
+*
+* Viewfinder refers to the video showing camera stream.
+*/
+type QrDimensionFunction =
+ (viewfinderWidth: number, viewfinderHeight: number) => QrDimensions;
+```
+
+This allows you to set dynamic QR box dimensions based on the video dimensions. See this blog article for example: [Setting dynamic QR box size in Html5-qrcode - ScanApp blog](https://scanapp.org/blog/2022/01/09/setting-dynamic-qr-box-size-in-html5-qrcode.html)
+
+> This might be desirable for bar code scanning.
+
+If this value is not set, no shaded QR box will be rendered and the scanner will scan the entire area of video stream.
+
+#### `aspectRatio` — Float, Example 1.777778 for 16:9 aspect ratio
+Use this property to render the video feed in a certain aspect ratio. Passing a nonstandard aspect ratio like `100000:1` could lead to the video feed not even showing up. Ideal values can be:
+| Value | Aspect Ratio | Use Case |
+| ----- | ------------ | -------- |
+|1.333334 | 4:3 | Standard camera aspect ratio |
+|1.777778 | 16:9 | Full screen, cinematic |
+|1.0 | 1:1 | Square view |
+
+If you do not pass any value, the whole viewfinder would be used for scanning.
+**Note**: this value has to be smaller than the width and height of the `QR code HTML element`.
+
+#### `disableFlip` — Boolean (Optional), default = false
+By default, the scanner can scan for horizontally flipped QR Codes. This also enables scanning QR code using the front camera on mobile devices which are sometimes mirrored. This is `false` by default and I recommend changing this only if:
+- You are sure that the camera feed cannot be mirrored (Horizontally flipped)
+- You are facing performance issues with this enabled.
+
+Here's an example of a normal and mirrored QR Code
+| Normal QR Code | Mirrored QR Code |
+| ----- | ---- |
+| <img src="https://scanapp.org/assets/github_assets/qr-code.png" width="200px" /> | <img src="https://scanapp.org/assets/github_assets/qr-code-flipped.png" width="200px" /><br /> |
+
+#### `rememberLastUsedCamera` — Boolean (Optional), default = true
+If `true` the last camera used by the user and weather or not permission was granted would be remembered in the local storage. If the user has previously granted permissions — the request permission option in the UI will be skipped and the last selected camera would be launched automatically for scanning.
+
+If `true` the library shall remember if the camera permissions were previously
+granted and what camera was last used. If the permissions is already granted for
+"camera", QR code scanning will automatically * start for previously used camera.
+
+#### `supportedScanTypes` - `Array<Html5QrcodeScanType> | []`
+> This is only supported for `Html5QrcodeScanner`.
+
+Default = `[Html5QrcodeScanType.SCAN_TYPE_CAMERA, Html5QrcodeScanType.SCAN_TYPE_FILE]`
+
+This field can be used to:
+- Limit support to either of `Camera` or `File` based scan.
+- Change default scan type.
+
+How to use:
+
+```js
+function onScanSuccess(decodedText, decodedResult) {
+ // handle the scanned code as you like, for example:
+ console.log(`Code matched = ${decodedText}`, decodedResult);
+}
+
+let config = {
+ fps: 10,
+ qrbox: {width: 100, height: 100},
+ rememberLastUsedCamera: true,
+ // Only support camera scan type.
+ supportedScanTypes: [Html5QrcodeScanType.SCAN_TYPE_CAMERA]
+};
+
+let html5QrcodeScanner = new Html5QrcodeScanner(
+ "reader", config, /* verbose= */ false);
+html5QrcodeScanner.render(onScanSuccess);
+```
+
+For file based scan only choose:
+```js
+supportedScanTypes: [Html5QrcodeScanType.SCAN_TYPE_FILE]
+```
+
+For supporting both as it is today, you can ignore this field or set as:
+```js
+supportedScanTypes: [
+ Html5QrcodeScanType.SCAN_TYPE_CAMERA,
+ Html5QrcodeScanType.SCAN_TYPE_FILE]
+```
+
+To set the file based scan as defult change the order:
+```js
+supportedScanTypes: [
+ Html5QrcodeScanType.SCAN_TYPE_FILE,
+ Html5QrcodeScanType.SCAN_TYPE_CAMERA]
+```
+
+#### `showTorchButtonIfSupported` - `boolean | undefined`
+> This is only supported for `Html5QrcodeScanner`.
+
+If `true` the rendered UI will have button to turn flash on or off based on device + browser support. The value is `false` by default.
+
+### Scanning only specific formats
+By default, both camera stream and image files are scanned against all the
+supported code formats. Both `Html5QrcodeScanner` and `Html5Qrcode` classes can
+ be configured to only support a subset of supported formats. Supported formats
+are defined in
+[enum Html5QrcodeSupportedFormats](https://github.com/mebjas/html5-qrcode/blob/master/src/core.ts#L14).
+
+```ts
+enum Html5QrcodeSupportedFormats {
+ QR_CODE = 0,
+ AZTEC,
+ CODABAR,
+ CODE_39,
+ CODE_93,
+ CODE_128,
+ DATA_MATRIX,
+ MAXICODE,
+ ITF,
+ EAN_13,
+ EAN_8,
+ PDF_417,
+ RSS_14,
+ RSS_EXPANDED,
+ UPC_A,
+ UPC_E,
+ UPC_EAN_EXTENSION,
+}
+```
+
+I recommend using this only if you need to explicitly omit support for certain
+formats or want to reduce the number of scans done per second for performance
+reasons.
+
+#### Scanning only QR code with `Html5Qrcode`
+```js
+const html5QrCode = new Html5Qrcode(
+ "reader", { formatsToSupport: [ Html5QrcodeSupportedFormats.QR_CODE ] });
+const qrCodeSuccessCallback = (decodedText, decodedResult) => {
+ /* handle success */
+};
+const config = { fps: 10, qrbox: { width: 250, height: 250 } };
+
+// If you want to prefer front camera
+html5QrCode.start({ facingMode: "user" }, config, qrCodeSuccessCallback);
+```
+
+#### Scanning only QR code and UPC codes with `Html5QrcodeScanner`
+```js
+function onScanSuccess(decodedText, decodedResult) {
+ // Handle the scanned code as you like, for example:
+ console.log(`Code matched = ${decodedText}`, decodedResult);
+}
+
+const formatsToSupport = [
+ Html5QrcodeSupportedFormats.QR_CODE,
+ Html5QrcodeSupportedFormats.UPC_A,
+ Html5QrcodeSupportedFormats.UPC_E,
+ Html5QrcodeSupportedFormats.UPC_EAN_EXTENSION,
+];
+const html5QrcodeScanner = new Html5QrcodeScanner(
+ "reader",
+ {
+ fps: 10,
+ qrbox: { width: 250, height: 250 },
+ formatsToSupport: formatsToSupport
+ },
+ /* verbose= */ false);
+html5QrcodeScanner.render(onScanSuccess);
+```
