My simple Hardhat setup script for my Solidity projects. It downloads hardhat via npm, creates folders, and installs a few of my favourite plugins.

setup-hardhat.sh

#!/bin/bash

# Simple script to preapre a project for smart contract development with hardhat.
# author: lajosdeme
# This will create an npm project, create folders for contracts, tests and scripts, and install the following dependencies:
# · hardhat
# · @openzeppelin/contracts
# · @nomiclabs/hardhat-ethers
# · @nomiclabs/hardhat-waffle
# · chai
# · ethers
# · ethereum-waffle
# · hardhat-contract-sizer
# · hardhat-gas-reporter 
# · hardhat-spdx-license-identifier


if [ "$1" == "" ]; then
    echo "Usage: setup-hardhat <Solidity compiler version>"
    exit 1
