Angular + Truffle = ? ÐAPPS - 角形+松露=? Ð应用程序

Angular + Truffle = ? ÐAPPS

This Trufflebox provides a base for Truffle Framework and Angular DAPP. and you can make transactions between accounts and scale you app with beautiful material design

This was generate

d with Angular CLI version 7.3.3.

Caution using node ˆ11 ??

Development server

Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Code scaffolding

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.

Build

  1. Install truffle, Angular CLI and an Ethereum client. If you don’t have a test environment
npm install -g truffle npm install -g @angular/cli npm install -g ganache-cli
  1. Download the box.
truffle unbox ng-es/angulartruffledapp
  1. Run your Ethereum client. For Ganache CLI:
ganache-cli

Note the mnemonic 12-word phrase printed on startup, you will need it later.

  1. Install the dependencies and Compile and migrate your contracts, into the directory Blockchain using :
npm install 
  1. Change the port in truffle-config.js
change the port in truffle-config.js 8545 in windows the port is 7545 but in linux the defaul port is  8545 
  1. Navigate into the Frontend Directory
npm install & ng serve , And lets Buidl 
  1. If you want to customize <===
  • First Change the contract in Blockchain/contracts or make your own contract and compile and migrate

  • Second Change the app/service/contract.service.ts with your builded contract .json and you custom directives and functions

Common errors and their solutions

Error Solution
Module not found: Error: Can't resolve '../../../../../Blockchain/build/contracts/Payment.json' during ng serve Run truffle compile
Error: the tx doesn't have the correct nonce. in MetaMask Reset MetaMask: Settings -> Reset Account //Warning only with test accounts
Error getting balance; see log. in UI, with Error: MetaCoin has not been deployed to detected network (network/artifact mismatch) in browser console Ensure you have started ganache, run truffle migrate and configured MetaMask to point to ganache

这个块菌盒为块菌框架和角状的DAPP提供了基础。您可以在账户之间进行交易,并使用漂亮的材质设计扩展您的应用程序,这是使用Angular CLI 7.3.3版生成的

Angular+Truffle=? Ð应用程序

注意使用节点ˆ11??

为dev服务器运行ng-serve。导航到http://localhost:4200/. 如果您更改任何源文件,应用程序将自动重新加载

运行ng generate component component name生成新组件。您还可以使用ng generate directive | pipe | service | class | guard | interface | enum | module

注意启动时打印的12个单词的助记符短语,稍后您将需要它

开发服务器

首先更改区块链blockchain/contracts中的contract或创建自己的contract并编译和迁移

代码脚手架

然后使用构建的contract.json更改app/service/contract.service.ts并自定义指令和函数

构建

  1. 安装truffle、Angular CLI和以太坊eth客户端。如果没有测试环境,请下载该框
npm install -g truffle npm install -g @angular/cli npm install -g ganache-cli
  1. 运行您的以太坊eth客户端。对于Ganache CLI:
truffle unbox ng-es/angulartruffledapp
  1. 安装依赖项并编译和迁移您的合同,使用:
ganache-cli

Note the mnemonic 12-word phrase printed on startup, you will need it later.

  1. 更改truffle-config.js中的端口
npm install 
  1. 导航到前端目录
change the port in truffle-config.js 8545 in windows the port is 7545 but in linux the defaul port is  8545 
  1. 如果您想自定义&lt;==
npm install & ng serve , And lets Buidl 
  1. 首先更改区块链blockchain/contracts中的契约,或者创建自己的契约并编译和迁移
  • 然后使用构建的contract.json更改app/service/contract.service.ts,然后自定义指令和函数
  • 将其分叉

常见错误及其解决方案

Error Solution
找不到模块:错误:在ng serve期间无法解析“../../../../../Blockchain/build/contracts/Payment.json” 运行truffle compile
错误:tx没有正确的nonce。在元掩码中 重置元掩码:设置-&gt;重置帐户//仅对测试帐户发出警告
获取余额时出错;见日志。在UI中,出现错误:MetaCoin尚未部署到浏览器控制台中检测到的网络(网络/工件不匹配) 请确保已启动ganache,运行truffle migrate并将MetaMask配置为指向ganache
