Steps to Set Up
Setting Up the Development Environment
1. Initialize the Project
Create a new directory for your project and initialize it with npm
:
This will generate a package.json
file for managing dependencies and scripts.
2. Install Solidity and Hardhat Dependencies
Hardhat is a powerful development environment for compiling, deploying, and testing Ethereum smart contracts. Install Hardhat along with ethers.js
for interacting with Ethereum, and the necessary plugins:
This command installs:
Hardhat: For development, testing, and deployment.
ethers.js: A library for interacting with Ethereum.
@nomiclabs/hardhat-ethers: A plugin that integrates Hardhat with
ethers.js
.
3. Create the Hardhat Configuration
Run Hardhat’s initialization command to generate the basic configuration and project files:
You will be prompted to select a task. Choose Create a basic sample project
or Create an advanced project
, depending on your needs. This will generate:
hardhat.config.js
: Your Hardhat configuration file.Sample contract, test, and script files.
4. Set Up the Folder Structure
5. Creating a Sample Solidity Contract
Inside the contracts/
folder, create a simple Solidity contract, e.g., MyContract.sol
:
6. Creating a Deployment Script
In the scripts/
folder, create a deployment script (deploy.js
):
7. Running the Deployment
To compile and deploy your contract locally:
Start a local Ethereum node using Hardhat:
Deploy your contract:
This will deploy your contract to a local test network.
8. Setting Up a Test File
In the test/
folder, create a test script (test.js
) using Hardhat's testing framework and ethers.js
:
9. Running the Tests
To run your tests:
10. Hardhat Network Configuration (Optional for Testnets)
To deploy on a real test network , configure your hardhat.config.js
