Introduction

This tool helps to create Web3.js based Hardhat project for contracts develpoment, testing and deployment. It includes a sample contract, some tests for that contract, and a script that deploys the contract.

The project utilizes:

• Hardhat as the development environment
• Chai for assertions
• web3.js for interacting with Ethereum

Web3.js Hardhat JS Template

Contains template using: Web3.js, Hardhat and JavaScript

Web3.js Hardhat TS Template

Contains template using: Web3.js, Hardhat and TypeScript

Prerequisites

• Node.js and npm (latest version)
• Basic understanding of JavaScript and Ethereum smart contracts

Getting Started

Follow these steps to set up and run the project locally.

Installation

1. Make a new directory:

   mkdir newproj

Note: If you install create-hardhat-web3 globally in your local computer using npm install -g create-hardhat-web3, step 2 and step 3 can be skipped and directly project can be created using step 4.

2. Create Node.js project using NPM or Yarn:

   npm init -y or yarn init -y

3. Install create-hardhat-web3 .

   npm i create-hardhat-web3 or yarn add create-hardhat-web3

4. Use required template for initilization of your project.

For Hardhat, Web3.js, Javascript project : npx create-hardhat-web3 init js

For Hardhat, Web3.js Typescript project :

npx create-hardhat-web3 init ts

Install dependencies

Once project is created using template install dependencies using: npm i or yarn

Compiling the Contract

After installing dependencies compile the smart contract with:

npx hardhat compile

This compiles contracts in the contracts/ directory and generates artifacts.

Running Tests

Execute tests with:

npx hardhat test

This runs all test files in the test/ directory.
