Auction

在substrate上实现了简单的拍卖功能

https://github.com/anakornk/substrate-developer-hackathon/blob/master/substrate/README.md

Setup syloUI

cd syloUI
yarn install
cd ios && pod install && cd ..
## START SUBSTRATE NODE
NODE_OPTIONS=--max_old_space_size=8192 react-native start
react-native run-ios

我们Sylo前端实现出现了点问题，未能按时完成：

1. 无法连接在onfinality 部署的节点，报了一下错误 console.error: "2019-08-04 16:57:51", " API-WS:", "disconnected from wss://mx-hashpire-test.ap1.onfinality.io code: 'undefined' reason: 'undefined'" 可以连接本地节点以及wss://cennznet-node-0.centrality.cloud:9944
2. commit df0402391a9f238a8105dd63b38d50a66611fb1a 把 commit 2424976f7af7f5eeb7740e12c3dfa3e0d270766b 和 commit ab7222cf7a9a06a2d58e466f3bc9c91da0c5bf9a 进行了merge之后，Sylo前端跑不动，报了错误 console.error: "2019-08-04 20:57:47", " API/DECORATOR:", {}，由于时间原因，现在还没找到具体原因和解决方式。

为了使得Sylo/React Native 环境能跑@Polkadot/api , 我们做了一下操作

yarn add node-libs-react-native
yarn add vm-browserify
yarn add bs58
yarn add @polkadot/api
yarn add @polkadot/keyring

修改metro.config.js

const nodeLibs = require("node-libs-react-native");
nodeLibs.bs58 = require.resolve("bs58");
nodeLibs.vm = require.resolve("vm-browserify");

module.exports = {
  transformer: {
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false
      }
    })
  },
  resolver: {
    extraNodeModules: nodeLibs
  }
};

在index.js增加

import 'node-libs-react-native/globals';

pod install

cd ios && pod install && cd ..

Setup Substrate node

cd substrate
./restart.sh
