Getting Started
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
Installation
BEFORE YOU INSTALL: please read the prerequisites
Start with cloning this repo on your local machine:
$ git clone https://github.com/centerprime/Node-Ethereum-SDK.git
To install and set up the library, run:
$ npm install node-ethereum-sdk
API
Create Wallet
import EthManager from "../src/centerprime.js"; var ethManager = new EthManager("Infura Url"); ethManager.createAccount("12345") .then(res => { console.log(res); });
Import Wallet by Keystore
import EthManager from "../src/centerprime.js"; var ethManager = new EthManager("Infura Url"); let keystore = {}; let password = ''; ethManager.importWalletByKeystore(keystore,password) .then(res => { console.log(res); });
Import Wallet by Private key
import EthManager from "../src/centerprimeSDK.js"; var ethManager = new EthManager("Infura Url"); let privateKey = ''; ethManager.importWalletByPrivateKey(privateKey) .then(res => { console.log(res); });
Get Ether balance
import EthManager from "../src/centerprimeSDK.js"; var ethManager = new EthManager("Infura Url"); let address = ''; ethManager.getEtherBalance(address) .then(res => { console.log(res); });
Get ERC20 token balance
import EthManager from "../src/centerprimeSDK.js"; var ethManager = new EthManager("Infura Url"); let tokenContractAddress = ''; let address = ''; ethManager.getERCTokenBalance(tokenContractAddress, address) .then(res => { console.log(res); });
Send ERC20 token
import EthManager from "../src/centerprimeSDK.js"; var ethManager = new EthManager("Infura Url"); let keystore = {}; let password = ''; let tokenContractAddress = ''; let toAddress = ''; let amount = ''; let chainId = ''; // 1 : Mainnet 3 : Ropsten ethManager.sendToken(keystore, password, tokenContractAddress , toAddress , amount , chainId) .then(res => { console.log(res); });
Send Ether
import EthManager from "../src/centerprimeSDK.js"; var ethManager = new EthManager("Infura Url"); let keystore = {}; let password = ''; let toAddress = ''; let amount = ''; let chainId = ''; // 1 : Mainnet 3 : Ropsten ethManager.sendEther(keystore, password , toAddress , amount , chainId) .then(res => { console.log(res); });
Demo
First run backend
npm install npm start
Second run frontend /frontend/
npm install npm start

先决条件
这个项目需要NodeJS（版本8或更高版本）和NPM。Node和NPM非常容易安装。要确保您的计算机上有可用的，请尝试运行以下命令。
$ npm -v && node -v 6.4.1 v8.16.0
目录
- 项目名称先决条件目录开始安装API创建钱包导入钱包密钥库私钥平衡以太平衡ERC20令牌平衡发送以太发送ERC20令牌演示
入门
这些说明将为您提供一份项目副本，并在本地计算机上运行，以供开发和测试之用。有关如何在活动系统上部署项目的说明，请参见部署。
安装
安装前：请阅读先决条件
从在本地计算机上克隆此repo开始：
$ git clone https://github.com/centerprime/Node-Ethereum-SDK.git
要安装和设置库，运行：
$ npm install node-ethereum-sdk
创建钱包
按私钥导入钱包
import EthManager from "../src/centerprime.js"; var ethManager = new EthManager("Infura Url"); ethManager.createAccount("12345") .then(res => { console.log(res); });
获取以太平衡
import EthManager from "../src/centerprime.js"; var ethManager = new EthManager("Infura Url"); let keystore = {}; let password = ''; ethManager.importWalletByKeystore(keystore,password) .then(res => { console.log(res); });
获取ERC20令牌平衡
import EthManager from "../src/centerprimeSDK.js"; var ethManager = new EthManager("Infura Url"); let privateKey = ''; ethManager.importWalletByPrivateKey(privateKey) .then(res => { console.log(res); });
发送ERC20令牌
import EthManager from "../src/centerprimeSDK.js"; var ethManager = new EthManager("Infura Url"); let address = ''; ethManager.getEtherBalance(address) .then(res => { console.log(res); });
发送以太
import EthManager from "../src/centerprimeSDK.js"; var ethManager = new EthManager("Infura Url"); let tokenContractAddress = ''; let address = ''; ethManager.getERCTokenBalance(tokenContractAddress, address) .then(res => { console.log(res); });
演示
import EthManager from "../src/centerprimeSDK.js"; var ethManager = new EthManager("Infura Url"); let keystore = {}; let password = ''; let tokenContractAddress = ''; let toAddress = ''; let amount = ''; let chainId = ''; // 1 : Mainnet 3 : Ropsten ethManager.sendToken(keystore, password, tokenContractAddress , toAddress , amount , chainId) .then(res => { console.log(res); });
Send Ether
import EthManager from "../src/centerprimeSDK.js"; var ethManager = new EthManager("Infura Url"); let keystore = {}; let password = ''; let toAddress = ''; let amount = ''; let chainId = ''; // 1 : Mainnet 3 : Ropsten ethManager.sendEther(keystore, password , toAddress , amount , chainId) .then(res => { console.log(res); });
