Depreciated! Please use Scandit-React-Native

The functionality of this package has been replicated to the Repository

yarn add scandit-react-native

Please make sure you transition to the official package, as this module will not receive any further updates. A warning has been added to the NPM listing.



We (Shoplink GmbH) are a premium scandit-partner and in the process of merging our internal react-native bridge into this repository for public access. This project was originally created by @Boris-c at the Digital Epidemiology Lab at EPFL, Switzerland (Salathe Group).

Run the iOS & Android Demo App

  • If you don't have an account, register on Scandit for a 30 day trail.
  • Download the Scandit iOS and Android BarcodeScan SDK
  • Clone this Repository (the demo app is inside the _demo_/ sub-folder)
  • cd _demo_
  • Set your API Key inside of the CONFIG.js file
  • run yarn install (or npm install if you only use npm)
  • Android
    • Copy the ScanditSDK folder (containing the .aar file in its root) into _demo_/android/app/src/vendor/
    • Start the App in the emulator or device via react-native run-android (emulator: you need to set a webcam as a camera in your emulator to test barcode scanning)
  • iOS
    • Copy the ScanditSDK folder (containing the .framework file in its root) into _demo_/ios/
    • Open the scandit.xcodeproj with xcode and set your developer account for the targets scandit & scanditTests
    • Connect your iOS device and run the build from xcode (simulator has no camera)
  • Use Storybook
    • This demo implements storybook for react native. You can run the storybook via npm run storybook. Don't forget to set your local IP of your computer inside of _demo_/app/storybook.js for on device testing. Default: localhost.

Option 1: Installation

$ react-native install react-native-scandit


  • Scandit's SDK is required. See below how to add it to the iOS and Android projects.
  • You need to allow access to the camera, both for iOS and Android. Barcode scanning can not be tested in the iOS Simulator.
  • The npm package is found in thee root of this repository.

Option 2: Manual Package installation for iOS and Android

$ yarn install react-native-scandit


  1. In Xcode, in the project navigator, right click LibrariesAdd Files to [your project's name]
  2. Go to node_modulesreact-native-scandit and add SGScandit.xcodeproj
  3. In Xcode, in the project navigator, select your project. Add libSGScandit.a to your project's Build PhasesLink Binary With Libraries
  4. Run your project (Cmd+R)<


  1. Open up android/app/src/main/java/[...]/
  • Add import com.reactlibrary.SGScanditPackage; to the imports at the top of the file
  • Add new SGScanditPackage() to the list returned by the getPackages() method
  1. Append the following lines to android/settings.gradle:
    include ':react-native-scandit'
    project(':react-native-scandit').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-scandit/android')
  2. Insert the following lines inside the dependencies block in android/app/build.gradle:
      compile project(':react-native-scandit')

Add the Scandit SDK to your Project


  1. Download Scandit SDK for iOS (, Scandit account required) and uncompress the archive.
  2. Copy the ScanditSDK folder to your ios/ folder. Note: This project assumes your ios project is under ios/ — if not, you need to change the ScanditSDK_Location user property under Build-Settings (way at the bottom) inside the SGScandit.xcodeproj manually.
  3. Continue with the Scandit install documentation (which is at the time as follows):
  • Drag the ScanditBarcodeScanner.framework from your ios/ScanditSDK folder (Finder) inside xcode, into your projects Frameworks/ group. (If you don't have a Frameworks Group, create one via right click -> Create Group. Name it "Frameworks").
  • A Model Pops-Up asking how xcode should add this file. Check both "Copy Items when needed" & "Create Groups". Select your target (should be selected) & hit ok.
  • Drag the ScanditBarcodeScanner.bundle from inside the frameworks package (ios/ScanditSDK/ScanditBarcodeScanner.framework/Resources/ScanditBarcodeScanner.bundle) into the Frameworks group as well.
  • The result should look something like this: AddedFrameworkAndBundle
  1. Scandit requires additional native libraries. At a minimum libiconv.tbd, libz.tbd and MediaPlayer.framework (if it does not compile, check the scandit documentation for the others libraries/frameworks and add the ones you are missing). Add them by selecting your Project-Root in Xcode -> Select your Target and add them under Linked Frameworks and Libraries via the "+".
  2. Scandit requires camera access. Make sure to add the "Privacy - Camera access" to your info.plist file in xcode (click "+" at the top and search for "Privacy - Camera..." via the auto complete. As a value, write a short description for what the camera will be used. For example "Camera is needed to scan barcode".
  3. Don't forget: You can not use the Camera in the simulator. So you need to use a real device for testing (!).


  1. Download Scandit SDK for Android (, Scandit account required) and uncompress the archive. The rest is in line with scandit android setup documentation by doing the following...
  2. Create a folder named vendor inside of android/app/src/.
  3. Place the ScanditSDK folder (the one containing the .aar file in its root) from the archive into android/app/src/vendor/ so that the path to the ScanditSDK is your-rn-project/android/app/src/vendor/ScanditSDK/ScanditBarcodeScanner.aar.
  4. Add to the android/build.gradlefile the flatdir path $rootDir/app/src/vendor/ScanditSDK. Do that inside of the allprojects { repositories { section, so the final result looks something like this:
allprojects {
    repositories {
        // SCANDIT INSERT ----->
        flatDir {
            dirs "$rootDir/app/src/vendor/ScanditSDK"
        // <----- SCANDIT INSERT END
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
  1. Go into your android/app/build.gradle und add to the dependencies section (located at the end of the gradle file) the line compile(name:'ScanditBarcodeScanner', ext:'aar') BEFORE the "compile project(':react-native-scandit')", so that your dependencies look something like this:
dependencies {
    // (..)
    compile(name:'ScanditBarcodeScanner', ext:'aar') // <--- INSERT BEFORE react-native-scandit compile statement
    compile project(':react-native-scandit')
    // (..)
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile ""
    compile "com.facebook.react:react-native:+"  // From node_modules
  1. Scandit requires camera access. Make sure to add to your AndroidManifest.xml (under android/app/src/main/) the folliwng permission:
    <uses-permission android:name="android.permission.CAMERA"/>


import React, { Component } from 'react';
import { AppRegistry, StyleSheet, View, Text, Alert } from 'react-native';

    this.handleContinueButton = this.handleContinueButton.bind(this);
    this.state = { showScanner: false }

  // Pause on a detected barcode (camera video is shown, but not parsed for barcodes).
  // Comparison: stop - startScanning() would freeze the camera image up on detection.
  onBarcode = (code) => {
    Alert.alert("Detected Barcode",,
      [{ text: 'CONTINUE', onPress: () => this.scanner.resumeScanning() }],
      { cancelable: false }

  maxNumberOfCodesPerFrame?: number;
  motionCompensationEnabled?: boolean;
  relativeZoom?: number;
  restrictedAreaScanningEnabled?: boolean;
  scanningHotSpot?: ScanditPointType;

Note: Due to traversal, boleans and numbers may have to be passed as strings. I.e. true = "true".

React Native Props:

settings: Scandit picker settings (see above)

onScan: on scan, called with the full object passed by Scandit's SDK

onCodeScan: on scan, called with the last scanned barcode only

onSettingsChange: obvious. Can be used to update the interface (i.e. a button that shows “Use front camera” / “Use back camera”)


getSettings(): Promise<*>

setSettings(settings: SettingsType): Promise<*>

startScanning(): Promise<*>

These return a promise, that can resolve or reject. On Android, I had to resolve to a promise implementation on the JS side (see SGNativeComponent.js), since React Native doesn’t seem to handle it (did I miss something?).





These don’t return a promise but could. As everything was quite experimental, I didn’t reach that point.

activity(): string

Ideally, this should return the current state ('active', 'paused', or 'stopped'), but it doesn't (TODO kind of thing...).


Please create issues if you encounter problems. In terms of contribution, Scandit maintains an official cordova plugin. It is technically possible to migrate cordova plugins to react-native (see links below).

  • Cordova Parity: If you have some ideas how to do so, or see missing (promise based) implementations, feel free to reach out or issue pull requests.
  • Testing: If you have an idea for automatic testing of the bridge (continues integration, E2E tests), let us know.
  • UI Overlays: Scandit is a barcode scanner. In most cases, you want to display additional information on top of it without covering interaction elements. We show animations and other information when interacting with barcodes. However, a best practice of overlaying views is still missing.
