CryptoAnts-Solidity-Technical-Interview - 加密技术面试

Quick start

The first things you need to do are cloning this repository and installing its dependencies:

npm install

Once installed, let’s run Hardhat’s testing network:

npx hardhat node

Then, on a new terminal, go to the repository’s root folder and run this to deploy your contract:

npx hardhat run scripts/deploy.js --network localhost

Note: There’s an issue in ganache-core that can make the npm install step fail.

If you see npm ERR! code ENOLOCAL, try running npm ci instead of npm install.

Open http://localhost:3000/ to see your Dapp. You will need to have Metamask installed and listening to localhost 8545.

User Guide

You can find detailed instructions on using this repository and many tips in its documentation.

  • Setting up the environment
  • Testing with Hardhat, Mocha and Waffle
  • Setting up Metamask
  • Hardhat’s full documentation

For a complete introduction to Hardhat, refer to this guide.

What’s Included?

Your environment will have everything you need to build a Dapp powered by Hardhat and React.

  • Hardhat: An Ethereum development task runner and testing network.
  • Mocha: A JavaScript test runner.
  • Chai: A JavaScript assertion library.
  • ethers.js: A JavaScript library for interacting with Ethereum.
  • Waffle: To have Ethereum-specific Chai assertions/mathers.
  • A sample frontend/Dapp: A Dapp which uses Create React App.

Troubleshooting

  • Invalid nonce errors: if you are seeing this error on the npx hardhat node console, try resetting your Metamask account. This will reset the account’s transaction history and also the nonce. Open Metamask, click on your account followed by Settings > Advanced > Reset Account.

CryptoAnts Solidity技术访谈

快速入门

首先需要克隆此存储库并安装其依赖项:

npm install

安装后,让我们运行Hardhat的测试网络:

npx hardhat node

然后,在新的终端上,转到存储库的根文件夹并运行此命令以部署您的契约:

npx hardhat run scripts/deploy.js --network localhost

注意:ganache core中有一个问题这会导致npm安装步骤失败。

如果您看到npm错误!如果是本地代码,请尝试运行npm ci而不是npm install。

打开http://localhost:3000/查看您的Dapp。您需要安装元掩码并侦听localhost 8545。

用户指南

您可以在其文档中找到有关使用此存储库的详细说明和许多提示。

  • 设置环境
  • 使用Hardhat、Mocha和华夫饼进行测试
  • 设置Metamask
  • Hardhat的完整文档

有关安全帽的完整介绍,请参阅本指南。

包括哪些内容?

您的环境将拥有构建由Hardhat和React提供动力的Dapp所需的一切。

  • Hardhat:以太坊eth开发任务运行程序和测试网络。Mocha:JavaScript测试运行者。
  • Chai:JavaScript断言库。
  • 以太.js:用于与以太坊eth交互的JavaScript库。华夫饼:拥有以太坊eth特有的Chai断言/数学。
  • 示例前端/Dapp:使用Create React App的Dapp。
  • 无效的nonce错误:如果在npx hardhat节点控制台上看到此错误,请尝试重置元掩码帐户。这将重置帐户的交易历史记录,也将重置nonce。打开元掩码,单击您的帐户,然后单击“设置”>“高级”>“重置帐户”。你知道吗
  • A sample frontend/Dapp: A Dapp which uses Create React App.

故障排除

  • Invalid nonce errors: if you are seeing this error on the npx hardhat node console, try resetting your Metamask account. This will reset the account’s transaction history and also the nonce. Open Metamask, click on your account followed by Settings > Advanced > Reset Account.
