@reclaimprotocol/inapp-capacitor-sdk

!NPM Version

This SDK allows you to integrate Reclaim's in-app verification process into your Capacitor application.

Refer Reclaim Protocol's official documentation for Capacitor SDK

Prerequisites

- A Reclaim account where you've created an app and have the app id, app secret.
- A provider id that you've added to your app in Reclaim Devtools.

Example

- See the Reclaim Example - Capacitor for a complete example of how to use the SDK in a Capacitor application.

Install

``bash
npm install @reclaimprotocol/inapp-capacitor-sdk
npx cap sync
`

Setup

$3

Add the following to your android/app/src/main/AndroidManifest.xml file under the tag:

`xml
android:name="org.reclaimprotocol.inapp_sdk.ReclaimActivity"
android:theme="@style/Theme.ReclaimInAppSdk.LaunchTheme"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize"
/>
`

add the following to the end of settings.gradle:

`groovy
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.PREFER_SETTINGS)
String flutterStorageUrl = System.env.FLUTTER_STORAGE_BASE_URL ?: "https://storage.googleapis.com"
String reclaimStorageUrl = System.env.RECLAIM_STORAGE_BASE_URL ?: "https://reclaim-inapp-sdk.s3.ap-south-1.amazonaws.com/android/repo"
repositories {
google()
mavenCentral()
maven {
url "$reclaimStorageUrl"
}
maven {
url "$flutterStorageUrl/download.flutter.io"
}
}
}
`

(Ignore if already added in settings.gradle from above)
or alternatively add the following repositories to the relevant repositories block:

`groovy
String flutterStorageUrl = System.env.FLUTTER_STORAGE_BASE_URL ?: "https://storage.googleapis.com"
String reclaimStorageUrl = System.env.RECLAIM_STORAGE_BASE_URL ?: "https://reclaim-inapp-sdk.s3.ap-south-1.amazonaws.com/android/repo"
maven {
url "$reclaimStorageUrl"
}
maven {
url "$flutterStorageUrl/download.flutter.io"
}
`

Some projects may require you to add the repositories to the root build.gradle file or your app-level build.gradle file's allprojects section.

$3

1. Make sure to define a global platform for your project in your Podfile with version 13.0 or higher.

`
platform :ios, '13.0' # or platform :ios, min_ios_version_supported
`

Ignore if you already have this declaration in your Podfile.

2. Add the following to your Podfile to override SDK dependency:

- This step is only required when facing issues with the resolved pod dependency.
- You can override the version of dependency when you wish to use a specific version of the SDK.
- You can add a declaration in your Podfile to install the SDK from cocoapods, or from a specific git tag, head, commit, or branch.

##### From cocoapods (recommended)

`ruby


Cocoapods is the recommended way to install the SDK.


pod 'ReclaimInAppSdk', '~> 0.7.0'
`

##### From a specific tag

`ruby
pod 'ReclaimInAppSdk', :git => 'https://github.com/reclaimprotocol/reclaim-inapp-ios-sdk.git', :tag => '0.7.0'
`

##### From git HEAD

`ruby
pod 'ReclaimInAppSdk', :git => 'https://github.com/reclaimprotocol/reclaim-inapp-ios-sdk.git'
`

##### From a specific commit

`ruby
pod 'ReclaimInAppSdk', :git => 'https://github.com/reclaimprotocol/reclaim-inapp-ios-sdk.git', :commit => 'eeb5a5484a5927217065e5c988fab8201cb2db2e'
`

##### From a specific branch

`ruby
pod 'ReclaimInAppSdk', :git => 'https://github.com/reclaimprotocol/reclaim-inapp-ios-sdk.git', :branch => 'main'
`

- After adding the dependency, your podfile may look like this:

`ruby
platform :ios, '13.0'

... some podfile content (removed for brevity)

target 'App' do
capacitor_pods
# Add your Pods here
# This is the line that you may need to add in your podfile.
pod 'ReclaimInAppSdk', '~> 0.7.0'
end
# ... rest of the podfile. (removed for brevity)
`

3. Run pod install inside the ios/ directory of your project.

`sh
cd ios/
pod install
`

#### Fixing runtime routing issue on iOS

This library uses a golang static library. Use of this has raised an issue in capacitor's swift router, causing the app to crash on startup with error message: Error: The file "public" couldn't be opened.

There are open issues on both capacitor and golang's issue tracker to dicuss this problem:
* https://github.com/ionic-team/capacitor/issues/7844
* https://github.com/golang/go/issues/58225

A workaround is available to fix this issue and requires a custom view controller to be used in ios.

1. First, create a PatchedViewController.swift file by opening Xcode, right-clicking on the App group (under the App target), selecting New File from Template from the context menu, choosing Cocoa Touch Class in the window, set the Subclass of: to UIViewController in the next screen, and save the file.





2. Next, select the Main.storyboard file in the Project Navigator, select the Bridge View Controller in the Bridge View Controller Scene, select the Identity Inspector on the right, and change the name of the custom class to PatchedViewController.




3. Finally, select the PatchedViewController.swift file in the Project Navigator and edit it to paste the following code:

`swift
import UIKit
import Capacitor

public struct PatchedRouter: Router {
public init() {}
public var basePath: String = ""
public func route(for path: String) -> String {
// FIX: Never pass an empty string here
let pathUrl = URL(fileURLWithPath: path.isEmpty ? "/" : path)

// If there's no path extension it also means the path is empty or a SPA route
if pathUrl.pathExtension.isEmpty {
return basePath + "/index.html"
}

return basePath + path
}
}

class PatchedViewController: CAPBridgeViewController {
// Passing our own router to fix the issue about go chdir on ios init issue
override open func router() -> any Router {
PatchedRouter()
}
}
`

#### Fixing performance issues on IOS physical devices

Your app performance will be severely impacted when you run debug executable on a physical device. Fixing this requires a simple change in your Xcode project xcscheme.

#### Method 1: Update Environment Variables for XCScheme (Recommended)
1. Open your iOS project (*.xcworkspace) in Xcode.
2. Click on the project target.
3. Click on the Scheme dropdown.

4. Click on the Edit Scheme button.
5. Click on the Run tab.
6. Click on the Arguments tab and check the Environment Variables section.

7. Add the following environment variable:
- Key: GODEBUG
- Value: asyncpreemptoff=1
8. Click on the Close button in the dialog and build the project.
9. Run the app on a physical device.

#### Method 2: Disable "Debug executable"

This method is not recommended but could be useful if you don't want to add environment variables to the xcscheme.

1. Open your iOS project (*.xcworkspace) in Xcode.
2. Click on the project target.
3. Click on the Scheme dropdown.

4. Click on the Edit Scheme button.
5. Click on the Run tab.
6. Uncheck the Debug executable checkbox.

Usage

To use Reclaim InApp Sdk in your project, follow these steps:

1. Import the @reclaimprotocol/inapp-capacitor-sdk package in your project file.

`js
import { ReclaimVerification } from '@reclaimprotocol/inapp-capacitor-sdk';
`

2. Initialize the ReclaimVerification class to create an instance.

`js
const reclaimVerification = new ReclaimVerification();
`

3. Start the verification flow by providing the app id, secret and provider id.

`js
const verificationResult = await reclaimVerification.startVerification({
appId: config.RECLAIM_APP_ID ?? '',
secret: config.RECLAIM_APP_SECRET ?? '',
providerId: providerId,
});
`

The returned result is a [ReclaimVerification.Response] object. This object contains a response that has proofs, exception, and the sessionId if the verification is successful.

$3

If the verification ends with an exception, the exception is thrown as a [ReclaimVerification.ReclaimVerificationException] object.

Following is an example of how to handle the exception using [error.type]:

`js
try {
// ... start verification
} catch (error) {
if (error instanceof ReclaimVerification.ReclaimVerificationException) {
switch (error.type) {
case ReclaimVerification.ExceptionType.Cancelled:
Snackbar.show({
text: 'Verification cancelled',
duration: Snackbar.LENGTH_LONG,
});
break;
case ReclaimVerification.ExceptionType.Dismissed:
Snackbar.show({
text: 'Verification dismissed',
duration: Snackbar.LENGTH_LONG,
});
break;
case ReclaimVerification.ExceptionType.SessionExpired:
Snackbar.show({
text: 'Verification session expired',
duration: Snackbar.LENGTH_LONG,
});
break;
case ReclaimVerification.ExceptionType.Failed:
default:
Snackbar.show({
text: 'Verification failed',
duration: Snackbar.LENGTH_LONG,
});
}
} else {
Snackbar.show({
text: error instanceof Error ? error.message : 'An unknown verification error occurred',
duration: Snackbar.LENGTH_LONG,
});
}
}
`

This error also contains sessionId, reason, and innerError that can be used to get more details about the occurred error.

`js
error.sessionId
error.reason
error.innerError
`

Migration

- Migration steps for 0.7.0
- Migration steps for 0.6.0

Advanced Usage

$3

`js
// Advanced Usage: Use ReclaimVerification.setOverrides for overriding sdk
reclaimVerification.setOverrides({
appInfo: {
appName: "Overriden Example",
appImageUrl: "https://placehold.co/400x400/png"
}
// .. other overrides
})
``

Note: Overriding again will clear previous overrides
