Hardhat

Getting setup with Hardhat

Setting up your environment

Create a new directory and navigate to it, and create a new project with npm init.

$ mkdir create-pharo-hardhat
$ cd create-pharo-hardhat
$ npm init -y

For this example, we'll use HardHat to compile our contracts.

$ npm i --save-dev hardhat

Now we can install the v1 Core contracts, so that we can inherit what we need to create a new Pharo.

$ npm i @pharo/contracts

Now we can create a new Hardhat config file in our environment, which can help us configure the compilation and testing processes for our contracts.

$ npx hardhat

Setting up Hardhat solidity version

For this example, we'll need to change ./hardhat.config.js to include the appropriate solidity version for compilling the Pharo core v1 contracts.

/**
*    @type import('hardhat/config').HardhatUserConfig
*/
module.exports = {
    solidity: "0.8.19",
};

Compiling Your Contract

We can compile our contracts with npx hardhat compile
