🌤 React Native Gigya SDK

SAP CDC/Gigya SDK for your React Native applications.

🏗️ Installation

Install the library :

yarn add react-native-gigya-sdk

If you haven't done so already, install a persistent storage library (like EncryptedStorage) as you'll need to provide it during setup. Just make sure your library exposes getItem() and setItem() functions.

iOS

See steps

Add the following line to your ios/Podfile:

pod 'Gigya'

From /ios, run:

pod install

If you don't already one, via Xcode, add a .swift file to your Xcode project and accept to Create Bridging Header:

//
//  Bridge.swift
//  GigyaSdkExample
//

import Foundation

If you're planing on providing Facebook login, search for the "Facebook" section and follow the full documentation to install and set up the Facebook SDK. You can then create a FacebookWrapper.swift file from Xcode and add it to your target (inside Compile Sources from the Build Phases tab) to handle the communication with the SDK. The file could look like so:

import Gigya

class FacebookWrapper: ProviderWrapperProtocol {

    private var completionHandler: (_ jsonData: [String: Any]?, _ error: String?) -> Void = { _, _  in }

    var clientID: String?

    private let defaultReadPermissions = ["email"]

    lazy var fbLogin: LoginManager = {
        return LoginManager()
    }()

    required init() {

    }

    func login(params: [String: Any]?, viewController: UIViewController?,
              completion: @escaping (_ jsonData: [String: Any]?, _ error: String?) -> Void) {
        completionHandler = completion
        
        fbLogin.logIn(permissions: defaultReadPermissions, from: viewController) { (result, error) in
            if result?.isCancelled != false {
                completion(nil, "sign in cancelled")
                return
            }

            if let error = error {
                completion(nil, error.localizedDescription)
            }

            let jsonData: [String: Any] = ["accessToken": result?.token?.tokenString ?? "", "tokenExpiration": result?.token?.expirationDate.timeIntervalSince1970 ?? 0]

            completion(jsonData, nil)
        }
    }

    func logout() {
        fbLogin.logOut()
    }
}

Same if you want Apple Sign In, search for the "Apple" section and follow the full documentation here and create a AppleSignInWrapper.swift file in the same manner as explained above. The file could look like so:

    func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {
        return self.viewController!.view.window!

Android

See steps

Add the desired Gigya SDK version to your android/build.gradle:

buildscript {
    ext {
      gigyaCoreSdkVersion = "core-v5.0.1"
    }
}

If you're planing on providing Facebook login, search for the "Facebook" section and follow the full documentation to install and set up the Facebook SDK.

💻 Usage

You can now initialize the SDK with your apiKey, dataCenter, application lang, storage solution & desired storageKey.

❗ Please make sure your storage library exposes getItem() and setItem() functions.

import GigyaSdk from 'react-native-gigya-sdk'
import EncryptedStorage from 'react-native-encrypted-storage'

// Before anything we initialize the SDK.
GigyaSdk.init({
  lang: 'en',
  apiKey: 'INSERT_GIGYA_API_KEY',
  dataCenter: 'eu1.gigya.com',
  storage: EncryptedStorage,
  storageKey: 'RANDOM_STRING'
})

// Now we can use it.
const myAccount = await GigyaSdk.login(email, password)
