Hardhat Docgen

Generate a static documentation site from NatSpec comments automatically on compilation with Hardhat.

Installation

yarn add --dev hardhat-docgen

Usage

Load plugin in Hardhat config:

require('hardhat-docgen');

Add configuration under the docgen key:

option	description	default
path	path to HTML export directory (relative to Hardhat root)	'./docgen'
clear	whether to delete old files in path on documentation generation	false
runOnCompile	whether to automatically generate documentation during compilation	false
only	Array of String matchers used to select included contracts, defaults to all contracts if length is 0	['^contracts/'] (dependent on Hardhat paths configuration)
except	Array of String matchers used to exclude contracts	[]

docgen: {
  path: './docs',
  clear: true,
  runOnCompile: true,
}

The included Hardhat task may be run manually:

yarn run hardhat docgen

By default, the hardhat compile task is run before generating documentation. This behavior can be disabled with the --no-compile flag:

yarn run hardhat docgen --no-compile

The path directory will be created if it does not exist.

The clear option is set to false by default because it represents a destructive action, but should be set to true in most cases.
