React Native Indy SDK

React Native Indy SDK wrapper.

Installation

with npm: $ npm install rn-indy-sdk --save

with Yarn: $ yarn add rn-indy-sdk

Link (for React Native lower than 0.60)

$ react-native link rn-indy-sdk

Android

Make sure there is a min. SDK version setup:

buildscript {
    ext {
        ...
        minSdkVersion = 21
        ...
    }
}

Add Sovrin Maven repository into android/build.gradle:

allprojects {
    repositories {
        ...
        maven {
            url 'https://repo.sovrin.org/repository/maven-public'
        }
        ...
    }
}

Download Android libindy binaries and copy them into android/app/src/main/jniLibs.

iOS

Add Indy.framework as dependency into your project. Beware that the library needs to be compiled with the same version of Swift as your project.

React Native wrapper for iOS is written in Swift so you need to Create briding header. In Xcode app menu go to File -> New -> File... Select Swift File from dialog window and click Next and Finish. Xcode shoud ask you "Would you like to configure an Objective-C briding header?" then select Create Bridinging Header.

Usage

import indy from 'rn-indy-sdk';

await indy.createWallet({ id: 'wallet-123' }, { key: 'key' });

You can see example project here https://github.com/jakubkoci/UseReactNativeIndySdk/. It currently shows only usage on Android.

Known Errors

Add setup of external storage permissions (Android)

I found an error with permission while calling createWallet when I was testing this package:

2020-01-27 16:25:02.300 9955-10044/com.usereactnativeindysdk E/log_panics: thread 'unnamed' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 13, kind: PermissionDenied, message: "Permission denied" }': libcore/result.rs:945

Modify onCreate method in MainActivity of your project where you want to use this library in a following way:

public class MainActivity extends ReactActivity {
  ...
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    ...
    File externalFilesDir = getExternalFilesDir(null);
    String path = externalFilesDir.getAbsolutePath();
    System.out.println("externalFilesDir=" + path);

    try {
      Os.setenv("EXTERNAL_STORAGE", path, true);
    } catch (ErrnoException e) {
      e.printStackTrace();
    }
    ...
  }
  ...
}

This should resolve the issue with permissions.
