# Pengambilan di React Native

Buka pengambilan dari aplikasi React Native dengan native module.

Back-end Anda membuat proses di Human Plugin dengan alur Journey dan `callbackUri` yang menggunakan URL scheme aplikasi Anda. Sebuah native module membuka `link` dari respons di `ASWebAuthenticationSession` pada iOS dan di Custom Tabs pada Android. Saat pengambilan berakhir, module menyelesaikan promise-nya dan aplikasi mengambil alih.

Simpan `id` Human Plugin dari respons pembuatan. Back-end Anda membaca hasilnya dengannya.

## Prasyarat

- React Native 0.71 atau lebih baru
- Xcode 14 atau lebih baru untuk iOS
- Android Studio untuk Android
- URL scheme yang unik untuk aplikasi Anda, seperti `myapp`

## 1. Buat proses dengan scheme Anda

Back-end Anda mengirim scheme sebagai `callbackUri`:

```json
{
  "flow": "humantoken",
  "clientId": "client-a",
  "correlationId": "order-1001",
  "credential": { "type": "DUI_TYPE_NG_BVN", "value": "<document number>" },
  "callbackUri": "myapp://callback"
}
```

dan mengembalikan `id` serta `link` ke aplikasi.

## 2. Buat bridge TypeScript

```typescript
// src/modules/CaptureModule.ts
import { NativeModules } from 'react-native';

const { CaptureModule } = NativeModules;

if (!CaptureModule) {
  throw new Error('CaptureModule not found. Make sure the native module is linked correctly.');
}

export const Capture = {
  openSession: (url: string): Promise<string> => CaptureModule.openSession(url),
};
```

## 3. Implementasikan module iOS

### Bridge Objective-C

```objc
// ios/CaptureModule.m
#import <React/RCTBridgeModule.h>

@interface RCT_EXTERN_MODULE(CaptureModule, NSObject)
RCT_EXTERN_METHOD(openSession:(NSString *)url
                  resolve:(RCTPromiseResolveBlock)resolve
                  reject:(RCTPromiseRejectBlock)reject)
@end
```

### Implementasi Swift

```swift
// ios/CaptureModule.swift
import AuthenticationServices

@objc(CaptureModule)
class CaptureModule: NSObject, ASWebAuthenticationPresentationContextProviding {

    private var session: ASWebAuthenticationSession?

    @objc func openSession(_ url: String,
                           resolve: @escaping RCTPromiseResolveBlock,
                           reject: @escaping RCTPromiseRejectBlock) {
        guard let sessionURL = URL(string: url) else {
            reject("INVALID_URL", "Invalid URL", nil)
            return
        }
        DispatchQueue.main.async {
            let newSession = ASWebAuthenticationSession(
                url: sessionURL,
                callbackURLScheme: "myapp"
            ) { callbackURL, error in
                self.session = nil
                if let callbackURL = callbackURL {
                    resolve(callbackURL.absoluteString)
                } else {
                    reject("SESSION_ERROR", error?.localizedDescription ?? "Session cancelled", error)
                }
            }
            newSession.presentationContextProvider = self
            newSession.prefersEphemeralWebBrowserSession = true
            newSession.start()
            self.session = newSession
        }
    }

    func presentationAnchor(for session: ASWebAuthenticationSession) -> ASPresentationAnchor {
        guard let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene,
              let window = windowScene.windows.first else {
            return ASPresentationAnchor()
        }
        return window
    }

    @objc static func requiresMainQueueSetup() -> Bool { return true }
}
```

## 4. Implementasikan module Android

Tambahkan dependensi ke `android/app/build.gradle`:

```groovy
implementation("androidx.browser:browser:1.5.0")
```

```kotlin
// android/app/src/main/java/<your.package>/CaptureModule.kt
package com.yourapp

import android.net.Uri
import androidx.browser.customtabs.CustomTabsIntent
import com.facebook.react.bridge.*

class CaptureModule(private val reactContext: ReactApplicationContext) :
    ReactContextBaseJavaModule(reactContext) {

    private var pendingPromise: Promise? = null

    override fun getName() = "CaptureModule"

    @ReactMethod
    fun openSession(url: String, promise: Promise) {
        pendingPromise = promise
        currentActivity?.runOnUiThread {
            CustomTabsIntent.Builder().build()
                .launchUrl(currentActivity!!, Uri.parse(url))
        } ?: promise.reject("NO_ACTIVITY", "No current activity")
    }

    fun handleRedirectUrl(uri: Uri) {
        if (uri.scheme == "myapp") {
            pendingPromise?.resolve(uri.toString())
            pendingPromise = null
        }
    }
}
```

```kotlin
// CapturePackage.kt
package com.yourapp

import com.facebook.react.ReactPackage
import com.facebook.react.bridge.NativeModule
import com.facebook.react.bridge.ReactApplicationContext
import com.facebook.react.uimanager.ViewManager

class CapturePackage : ReactPackage {
    override fun createNativeModules(ctx: ReactApplicationContext): List<NativeModule> =
        listOf(CaptureModule(ctx))
    override fun createViewManagers(ctx: ReactApplicationContext): List<ViewManager<*, *>> =
        emptyList()
}
```

Daftarkan di `MainApplication.kt`:

```kotlin
override fun getPackages(): List<ReactPackage> =
    PackageList(this).packages.apply {
        add(CapturePackage())
    }
```

Tangani kembalinya pengguna di `MainActivity.kt`:

```kotlin
override fun onNewIntent(intent: Intent) {
    super.onNewIntent(intent)
    intent.data?.let { uri ->
        if (uri.scheme == "myapp") {
            val module = reactInstanceManager
                .currentReactContext
                ?.getNativeModule(CaptureModule::class.java)
            module?.handleRedirectUrl(uri)
        }
    }
}
```

## 5. Daftarkan scheme Anda di Android

Di `AndroidManifest.xml`:

```xml
<uses-feature android:name="android.hardware.camera" android:required="false" />
<uses-permission android:name="android.permission.CAMERA" />

<activity android:name=".MainActivity" ...>
    <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="myapp" android:host="callback" />
    </intent-filter>
</activity>
```

## 6. Mulai pengambilan

```typescript
import { Capture } from './modules/CaptureModule';

try {
  await Capture.openSession(link);
  // Pengambilan berakhir. Minta back-end Anda membaca hasilnya
  // dengan GET /v1/processes/{id}, menggunakan id Human Plugin.
} catch {
  // Orang tersebut menutup sesi.
}
```
