ARNIMA SDK (Aries React-NatIve Mobile Agent)

ARNIMA is an open-source React Native SDK for building Aries Mobile Agents. ARNIMA attempts to meet the needs / asks of many members from the Aries community, mainly React Native developers, who are looking forward to build cross-platform Aries Mobile Agents using React Native stack.

This React-Native SDK is compatible to be used with both Android and iOS platforms. Please refer Installation section on how to set up the sdk and start running. This SDK is compliant and interoperable with the standards defined in the Aries RFCs.

What's in the name

Arnima (Hindi: अर्निमा, meaning "First ray of Sun") is a girl name in India whose zodiac sign is Aries 😉

Dependencies

• The node 10.18.1 (To check, nvm ls) is required to install mobile agent specific dependencies like realm

1. Install nvm

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash

2. Restart the terminal
3. Confirm it's been installed with the following command:

nvm --version

4. Install node 10 using nvm

nvm install 10.18.1

5. Make sure you're using the right version of node

nvm use 10.18.1

Installation

1. Clone this repository git clone *****
2. cd into the repo cd mobile-sdk
3. Create the ARNIMA mobile agent package by using the following command npm pack
4. This will create a *.tgzfile inside current directory.
5. Copy the *.tgzfile and paste it inside the root of your mobile wallet project.
6. Inside your project of mobile app wallet's package.json, add this to the dependencies block:

"react-native-arnima-sdk": "./<MOBILE_AGENT_PACKAGE>.tgz"

7. After this, run npm install, and the sdk will automatically unpack and install inside node_modules.
8. Install the following SDK dependencies in your wallet application:

• Realm

npm install realm

• buffer

npm install buffer

• Socket Client

npm install socket.io-client

• Base64Url

npm install base64url

• EventListener

npm i react-native-event-listeners

Android: Link Mobile Agent SDK

1. Execute react-native link
2. Edit the android/ level build.gradle file and add a repositories section:

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

iOS: Link Mobile Agent SDK

1. Include below lines on top of your project's Podfile.

source 'https://github.com/CocoaPods/Specs.git'
source 'https://github.com/hyperledger/indy-sdk.git'

2. Change platform :ios, '9.0' to platform :ios, '13.0'
3. Add following line to include sdk pod to your project.

pod 'ArnimaSdk', :path => '../node_modules/react-native-arnima-sdk'

4. Do pod install.
5. You need to download and replace the file Indy.framework from Pods folder inside your Mobile app project from the following link (base on your xcode & swift version) Download from - https://drive.google.com/drive/folders/1_WJ3mEHqk5GHH9p5SI4bRKRXPwy5w_0e?usp=sharing, Replace at - <Your_Project>/ios/Pods/libindy/

Using the SDK

1. Import the library

import ArnimaSDK from 'react-native-arnima-sdk'

2. Use the following methods

Methods

createWallet(config, credential, label) -> Array

This method is called after the user has set up their wallet name & passcode for the first time.

config: JSON - Wallet configuration that takes in the wallet name as an id (e.g. Proof)

{
  id: <WALLET_NAME>
}

credential: JSON - Wallet credentials json that takes in the passcode the user has setup during onboarding

{
    key: <PASSCODE>
}

label : String - Your label to show to the counter party during connection

Example:

import ArnimaSDK from 'react-native-arnima-sdk'

const wallet = await ArnimaSDK.createWallet(
  { id: 'John' },
  { key: '354016' },
  'John'
)

Returns:

Success: Array[<public_did>, , ] Sample Output: ["K7P6Xoe31NBYn7md8qBm4F", "AsVcY4GUvJyeP2k78vJK2mTuPHT1sSdZjQBXbCUyXEbz", "John"]

Error: Below is a list of anticipated errors

1. Storage permissions error. Sample: {"code":"114","message":"org.hyperledger.indy.sdk.IOException: An IO error occurred."}]
2. Wallet already error. Sample: {"code":"203","message":"Wallet already exists."}].

ConnectWithMediator(url, apiType, apiBody, poolConfig) -> Boolean

This method connects to an instantiated service of a mediator agent that is in charge of holding messages if the application is offline and to push messages to this sdk the moment mobile app is active.

url: String - endpoint url of the instantiated mediator agent

"http://10.10.10.10:8001/discover/"

apiType: String - Describes the way by which we are accessing the endpoint (in this case, we are using POST)

"POST"

apiBody: String - Stringified JSON that contains the wallet information needed to attach to the mediator agent

JSON.stringify({
    myDid: "<WALLET_PUBLIC_DID>",
    verkey: "<WALLET_VERIFIED_KEY>",
    label: "<WALLET_LABEL>",
    firebaseToken: "<FIREBASE_TOKEN> OR '' "
})

poolConfig: String - A genesis transaction string received in response of /register-device endpoint.

Socket Methods

We are using socket for communication between app and mediator agent.

socketInit() -> void

Example:

import ArnimaSDK from 'react-native-arnima-sdk'

indy.socketInit()

socketEmit() -> void

Example:

import ArnimaSDK from 'react-native-arnima-sdk'

indy.socketEmit()

socketListener() -> void

Example:

import ArnimaSDK from 'react-native-arnima-sdk'

indy.socketListener()

Receive an event on your mobile app

You can receive event in mobile application when connection is established. Receive the credentials and proof request.

import { EventRegister } from 'react-native-event-listeners';

componentDidMount() {
        this.listener = EventRegister.addEventListener('SDKEvent', (data) => {
            // write your code here...
        });
    }

    componentWillUnmount() {
        EventRegister.removeEventListener(this.listener);
    }
