React Native Elastos Carrier Plugin

Elastos Carrier is a decentralized peer-to-peer platform that takes over all network traffic between virtual machines and conveys information on applications’ behalf.

This repo is the react native bridge between native carrier lib and javascript api. so developer could easy to create a elastos dapp with carrier module by javascript.

The release version for plugin is here

Getting started

npm install --save elastos-unity-carrier

react-native link elastos-unity-carrier

Next step

iOS

  • open xcode
  • add ElastosCarrier.framework to Linked Frameworks and Libraries from /node_modules/react-native-elastos-carrier/ios/Carrier folder
  • run project

Android

add following lines to project build.gradle

flatDir{
    dirs "$rootDir/../node_modules/react-native-elastos-carrier/android/libs"
}

under allprojects repositories block.

Unit test with Jest

For plugin JS side, integrate with Jest to mock and test.

npm test

ESLint to format code

npm run lint

Usage

const carrier = new Carrier('app_name', {
    // carrier callback
});
await carrier.start();
