Package Exports

@sealsc/polkadot-wrapper

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@sealsc/polkadot-wrapper) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

polkadot-wrapper

概述

polkadot-wrapper库是一系列模块的集合，服务于波卡生态系统的各个功能,可帮助您编写可与多个区块链一起使用的代码, 使用插件模型和统一接口来完成区块链交易的构建、签名、发送等常见的区块链功能

api-actions 用来与波卡区块链交互
api-connector 用来与polkadot钱包进行交互
api-contract 用来与波卡区块链合约交互

actions模块的示例代码

获取最新区块高度

  // 初始化Actions
  let Action = await new Actions()
  // 调用getBlockNumber方法,获取最新区块高度
  let BlockNumber = await Action.actions.getBlockNumber()

connector模块的示例代码

连接钱包

  // 初始化Actions
  let Action = await new Actions()
  // 调用link方法,连接钱包
  await Action.connector.link()

contract模块的示例代码

创建新的合约实例,调用合约name方法

  // 初始化Actions
  let Action = await new Actions()
  // 调用loadContract方法,创建新的合约实例
  let Contract = await Action.contract.loadContract(ERC20,'0xxxxxxxxxx')
  let name =  await Action.contract.offChainCall(Contract.data,'name',[],'','')

如何开始？

只需安装polkadot-wrapper库即可开始

$ yarn add @sealsc/polkadot-wrapper

然后你需要创建一个 Action 的实例,设置provider

let Action = await new Actions()    
Action.init('wss://rpc.polkadot.io')

运行ts文件和示例

$ yarn test
