Mostly automatic installation (pre RN 0.60)

$ react-native link react-native-klarna

For RN >= 0.60 please follow After either route step for iOS and for Android within repositories block of the dependencies block add:

```gradle
    maven { url 'https://x.klarnacdn.net/mobile-sdk/'}
```

Manual installation

iOS

CocoaPods route

1. In Podfile add pod 'RNKlarna', :path => '../node_modules/react-native-klarna'
2. Run pod install.

Manual route (only available for version < 0.2.1)

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-klarna and add RNKlarna.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNKlarna.a to your project's Build Phases ➜ Link Binary With Libraries
4. Drag and drop KlarnaCheckoutSDK.framework from node_modules/react-native-klarna/ios/Frameworks, (deselct copy resources) make sure that it appears in project's Build Phases ➜ Link Binary With Libraries
5. Check that Framework and Header search paths in Build Settings contain $(SRCROOT)/../node_modules/react-native-klarna/ios/Frameworks

After either route

Add the following key with your bundle name to your Info.plist:

    <key>ReturnURLKlarna</key>
    <string>YOUR_BUNDLE_NAME</string>

Android

1. Open android/app/src/main/java/[...]/MainActivity.java

• Add import com.rnklarna.RNKlarnaPackage; to the imports at the top of the file
• Add new RNKlarnaPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-klarna'
   project(':react-native-klarna').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-klarna/android')

3. Insert the following lines inside the android block in android/app/build.gradle:

   compileOptions {
       sourceCompatibility JavaVersion.VERSION_1_8
       targetCompatibility JavaVersion.VERSION_1_8
   }

   add the following line inside the dependencies block:

   implementation project(':react-native-klarna')

   and within repositories block of the dependencies block add:

       maven { url 'https://x.klarnacdn.net/mobile-sdk/'}

   In summary, the following changes should be made:

   android {
     ...
     compileOptions {
       sourceCompatibility JavaVersion.VERSION_1_8
       targetCompatibility JavaVersion.VERSION_1_8
     }
     ...
   }
   dependencies {
     ...
     implementation project(':react-native-klarna')
     ...
     repositories {
       ...
       maven { url 'https://x.klarnacdn.net/mobile-sdk/'}
       ...
     }
   }

4. Register an intent-filter:

   <intent-filter>
     <action android:name="android.intent.action.VIEW" />
     <category android:name="android.intent.category.DEFAULT" />
     <category android:name="android.intent.category.BROWSABLE" />
   
     <data android:scheme="<your-custom-scheme>" />
     <data android:host="<your-custom-host>" />
   </intent-filter>

5. Make sure that activity is using launchMode singleTask or singleTop:

   <activity
     android:launchMode="singleTask|singleTop">

Usage Example

Typical usage example is shown below, there is also an example app in example/basic

import RNKlarna, { NativeEvent } from 'react-native-klarna';

import React, { PureComponent } from 'react';
import { connect } from 'react-redux';
...

export class KlarnaScreen extends PureComponent {
  state {
    snippet: '' // <- or initial snippet from your backend
    loadError: false,
  }

  onComplete = async (event: NativeEvent) => {
    const { signalType } = event;
    if (signalType === 'complete') {
      const { orderId } = this.props;
      /*
      1. Perform call to the backend
      2. Retrieve the order status and confirmation snippet.
      3. Update the Klarna component with the confirmation snippet once the order status is final
      4*. If an error occurs, set snippet to 'error' to dismiss loading screen
      */
     try {
      const result = await getConfirmationSnippet(orderId);
      const { newSnippet, orderStatus, loadError } = result;
      if orderStatus {
        this.setState({ snippet: newSnippet });
      } 
     } catch (error) {
       this.setState({ loadError: true });
     }
    }
  };

  render() {
    let { snippet } = this.state;
    const { loadError } = this.state;
    if (loadError) {
      snippet = 'error';
    }
    return (
      <View>
        <RNKlarna snippet={snippet} onComplete={this.onComplete} />
        ...
      </View>
    );
  }
}
