React Native VK authorization wrapper

Installation

yarn add rn-vk-auth

or

npm install rn-vk-auth --save

Then you should configure native parts:

Android

1. Edit android/settings.gradle

   ...
   include ':rn-vk-auth'
   project(':rn-vk-auth').projectDir = new File(settingsDir, '../node_modules/rn-vk-auth/android')
   ...

2. Edit android/app/build.gradle

   ...
   
   dependencies {
       ...
       compile project(':rn-vk-auth')
   }

3. Edit android/app/src/main/java/<...>/MainApplication.java

   ...
   
   import com.mastereugene.vkauth.VKAuthPackage; //<---- import package
   
   public class MainApplication extends Application implements ReactApplication {
   ...
     @Override
     protected List<ReactPackage> getPackages() {
       return Arrays.<ReactPackage>asList(
           new MainReactPackage(),
           ...
           new VKAuthPackage()//<---- Add package
         );
     }
   ...
   }

4. In your AndroidManifest.xml, add following line inside <application> element:

   <activity android:name="com.vk.sdk.VKServiceActivity" android:label="ServiceActivity" android:theme="@style/VK.Transparent" />

5. Add VK Application ID to resources (main/res/values/strings.xml) so the module will initialize with it at startup:

   <integer name="com_vk_sdk_AppId">VK_APP_ID</integer>

   (In this example, VK_APP_ID should be replaced with your real VK App ID you've got from VK manage panel)

iOS

1. Add rn-vk-auth to your XCode project. To do so, go to node_modules/rn-vk-auth/ios directory inside your project and drag VKAuthorization.xcodeproj into your XCode project

   Then add library libRNVkontakteLogin.a to Linked Frameworks and Libraries section.

2. Add VKSdkFramework.framework to embedded binaries. This can be done in Embedded binaries section of General Tab of your project in XCode.

3. Add following fragment to your info.plist:

   <key>LSApplicationQueriesSchemes</key>
   <array>
       <string>vk</string>
       <string>vkauthorize</string>
   </array>

4. To use authorization via VK App you need to setup a url-schema of your application. Open your application settings then select the Info tab. In the URL Types section click the plus sign. Enter vk+APP_ID to the Identifier and URL Schemes fields.

   Alternatively, you can add following to your info.plist:
   
   ```xml
   <key>CFBundleURLTypes</key>
   <array>
       <dict>
           <key>CFBundleTypeRole</key>
           <string>Editor</string>
           <key>CFBundleURLName</key>
           <string>vk1111111</string>
           <key>CFBundleURLSchemes</key>
           <array>
               <string>vk1111111</string>
           </array>
       </dict>
   </array>
   ```
   
   Here vk1111111 is your real VK App ID you've got from VK App manage panel

5. In your AppDelegate.m, you need to import VK SDK:

   #import <VKSdkFramework/VKSdkFramework.h>

   and then add following code (both methods are required):

   //iOS 9 workflow
   - (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
      [VKSdk processOpenURL:url fromApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]];
      return YES;
   }
   
   //iOS 8 and lower
   -(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
   {
      [VKSdk processOpenURL:url fromApplication:sourceApplication];
      return YES;
   }

6. (Optional) You can add your VK Application ID to info.plist so the module will initialize with it at startup:

   <key>VK_APP_ID</key>
   <integer>1111111</integer>

   If you do so, you won't need to call VKLogin.initialize(vkAppId) from your JS code.

The last step is to run pod install:

cd ios && pod install

Usage

Import module in your JS code

import VKAuth from 'rn-vk-auth';

Initialize VK with your APP ID once somewhere during your app startup(only iOS):

componentDidMount() {
  VKAuth.initialize(1111111);
}

Check if user is logged in, perform login and logout:

const isLoggedIn = await VKAuth.isLoggedIn();
const auth = await VKAuth.login(['friends', 'photos', 'email']);
console.log(auth.access_token);
await VKAuth.logout();
