# Practical Sample With Hardhat + Solidity
|
|
|
|
A fully functional Smart Contract wrriten with ```solidity```, ```node.js``` and using ```Hardhat``` to show usage of all kinds of standard development features, including:
|
|
* running blockchain node in localhost - ```hardhat``` & ```ganache```
|
|
* solidity prettier code beautifier setup
|
|
* standard of developing Smart Contract with ```solidity```
|
|
* standard of developing ```node.js``` script to use ```hardhat``` library efficiently
|
|
* auto verify contract in Etherscan.io
|
|
* creating automate test cases
|
|
* creating tasks etc.
|
|
* gitea version control
|
|
|
|
This project mainly to keep as a reference for future Web 3.0 Developments.

|
|
## 1. Git Version Control
|
|
First time initialize:
|
|
```
|
|
git config --global user.name "hoelee"
|
|
git config --global user.email "[email protected]"
|
|
git init .
|
|
git add .
|
|
git checkout -b main
|
|
git commit -m "Initial Commit"
|
|
git remote set-url origin https://username:[email protected]/hoelee/ethers-simple-storage.git
|
|
git credential-cache exit // Fix Credential Error
|
|
```
|
|
|
|
Standard Update:
|
|
```
|
|
git add .
|
|
git commit -m "Describe what changes"
|
|
git push -u origin main
|
|
```
|
|
|
|
Development need exlude file can create root file with name .gitignore
|
|
```
|
|
.env
|
|
node_modules
|
|
.encryptedkey.json
|
|
```
|
|
|
|
## 2. Setup Visual Studio Code Development Environment
|
|
|
|
Windows need to download install WSL
|
|
```
|
|
wsl --set-default Ubuntu-22.04
|
|
mkdir theProjectFolderName
|
|
cd theProjectFolderName
|
|
code .
|
|
// Install nvm
|
|
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
|
|
nvm install 16.14.2
|
|
nvm install node.js
|
|
nvm install 18 // Update node JS to v18
|
|
```
|
|
Visual Studio need to update code setting
|
|
```
|
|
"[solidity]": {
|
|
"editor.defaultFormatter":"NomicFoundation.hardhat-solidity"
|
|
}
|
|
```
|
|
Preparing of solidity development environment:
|
|
```
|
|
corepack enable // Enable yarn
|
|
yarn install solc
|
|
yarn add [email protected]
|
|
yarn solcjs --bin --abi --include-path node_modules/ --base-path . -o . SimpleStorage.sol
|
|
yarn add ethers // Compiler Error, Downgraded to v5.7.2
|
|
yarn add fs-extra
|
|
yarn add dotenv
|
|
yarn add prettier
|
|
yarn add prettier-plugin-solidity
|
|
```
|
|
Preparing of Hardhat Development Environment
|
|
```
|
|
yarn init
|
|
// Manual delete main: index.js in package.json
|
|
yarn add --dev hardhat // Production no need --dev
|
|
nvm install 18
|
|
nvm use 18
|
|
nvm alias default 18
|
|
corepack enable // Enable yarn
|
|
yarn hardhat
|
|
yarn add --dev prettier prettier-plugin-solidity
|
|
yarn add --dev dotenv
|
|
yarn add --dev @nomiclabs/hardhat-etherscan // Auto verify Etherscan Samrt Contract
|
|
```
|
|
Other Terminal Useful Command
|
|
```
|
|
// For Debuging Hardhat
|
|
npx hardhat --versose
|
|
|
|
// For Recompile
|
|
yarn hardhat clean // Or manual delete artifacts & cache folder
|
|
npm install
|
|
|
|
// For Listing Hardhat Local Blockchain node
|
|
yarn hardhat accounts
|
|
yarn hardhat node // Run in Dedicated Terminal, Getting Blockchain server
|
|
yarn hardhat console --network localhost // Short Life To Test Solidity Code In Terminal
|
|
yarn hardhat compile
|
|
yarn hardhat run scripts/deploy.js --network localhost
|
|
yarn hardhat custom-task-name
|
|
// Need create file in /tasks/custom-task-name.js
|
|
// Add import in hardhat.config.js -> requir("/tasks/custom-task-name");
|
|
yarn hardhat test
|
|
yarn hardhat test --grep customKeyword
|
|
// Only will run the test with describe test that contain "customKeyword"
|
|
```
|
|
|
|
|
|
## 3. Known Issue
|
|
* Cannot use ```expect``` in test, most probably due to the dependencies mismatched. Future will upgrade and test newer version dependencies.
