React Native Version

BlinkInput React Native was built and tested with React Native v0.61.5

First generate an empty project if needed:

react-native init --version="0.61.5" NameOfYourProject

cd <path_to_your_project>
npm i --save blinkinput-react-native

react-native link blinkinput-react-native

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like BlinkInput in your projects.

  • If you wish to use version v1.4.0 or above, you need to install Git Large File Storage by running these comamnds:
brew install git-lfs
git lfs install
  • Be sure to restart your console after installing Git LFS

Installing pods

From react-native 0.60 CocoaPods are now part of React Native's iOS project.

Go to NameOfYourProject/ios folder and install Pods

pod install

Our blinkinput-react-native depends on latest PPBlinkOCR pod so it will be installed automatically.

To run iOS application, open NameOfYourProject.xcworkspace, set Your team for every Target in General settings and add Privacy - Camera Usage Description key to Your info.plist file and press run

Android

Add microblink maven repository to project level build.gradle:

allprojects {
  repositories {
    // don't forget to add maven and jcenter
    mavenLocal()
    jcenter()
    
    // ... other repositories your project needs
    
    maven { url "http://maven.microblink.com" }
  }
}

Demo

This repository contains initReactNativeDemoApp.sh script that will create React Native project and download all of its dependencies. You can run this script with following command:

./initReactNativeDemoApp.sh

Usage

To use the module you call it in your index.android.js or index.ios.js file like in the example app. Available recognizers and API documentation is available in JS API files.
