Hardhat Abigen Plugin

This repository contains a plugin for Hardhat, a popular Ethereum development environment. The Hardhat Abigen Plugin generates ABI (Application Binary Interface) files from smart contracts, making it easier to interact with contracts on the Ethereum blockchain.

Installation

To use this plugin, follow these steps:

1. Ensure you have Node.js installed on your machine.
2. Install Hardhat by running npm install --save-dev hardhat.
3. Install the Hardhat-Abigen plugin by running npm install --save-dev hardhat-abigen.

Usage

After installing the plugin, you can import it in your TypeScript or JavaScript files by adding the following line:

import "hardhat-abigen";

or

require("hardhat-abigen");

This will enable the necessary functionality provided by the plugin.

Configuration

The Hardhat-Abigen plugin supports a configuration file that allows you to customize its behavior. Create a file named hardhat.config.js or hardhat.config.ts in the root directory of your project and add the following configuration options:

JavaScript

module.exports = {
  // ...other configuration options...

  abigen: {
    outDir: "abi",            // The output directory for generated ABI files (default: "abi")
    inDir: "contracts",       // The input directory containing your contract files (default: "contracts")
    includeContracts: ["*"],  // An array of contract patterns to include in the generate ABIs (default: ["*"])
    excludeContracts: [],     // An array of contract patterns to exclude from the generate ABIs (default: [])
    space: 2,                 // The number of spaces to use for indentation in the generated ABIs (default: 2)
    autoCompile: true         // Whether to automatically compile contracts before generating ABIs (default: true)
  },
};

TypeScript

import { HardhatUserConfig } from "hardhat/config";

const config: HardhatUserConfig = {
  // ...other configuration options...

  abigen: {
    outDir: "abi",            // The output directory for generated ABI files (default: "abi")
    inDir: "contracts",       // The input directory containing your contract files (default: "contracts")
    includeContracts: ["*"],  // An array of contract patterns to include in the generate ABIs (default: ["*"])
    excludeContracts: [],     // An array of contract patterns to exclude from the generate ABIs (default: [])
    space: 2,                 // The number of spaces to use for indentation in the generated ABIs (default: 2)
    autoCompile: true         // Whether to automatically compile contracts before generating ABIs (default: true)
  },
};

export default config;

Make sure to replace the values with your desired configuration options.

Generating ABIs

To generate ABIs for your contracts, run the following command:

npx hardhat abigen

This will compile your contracts (if autoCompile is set to true) and generate the corresponding ABI files in the specified outDir directory.
