Package Exports

hardhat-abi-exporter

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hardhat-abi-exporter) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Hardhat ABI Exporter

Export Ethereum smart contract ABIs on compilation via Hardhat.

Versions of this plugin prior to 2.0.0 were released as buidler-abi-exporter.

Installation

yarn add --dev hardhat-abi-exporter

Usage

Load plugin in Hardhat config:

require('hardhat-abi-exporter');

Add configuration under the abiExporter key:

option	description	default
`path`	path to ABI export directory (relative to Hardhat root)	`'./abi'`
`clear`	whether to delete old files in `path` on compilation	`false`
`flat`	whether to flatten output directory (may cause name collisions)	`false`
`only`	`Array` of `String` matchers used to select included contracts, defaults to all contracts if `length` is 0	`[]`
`except`	`Array` of `String` matchers used to exclude contracts	`[]`
`spacing`	number of spaces per indentation level of formatted output	`2`

abiExporter: {
  path: './data/abi',
  clear: true,
  flat: true,
  only: [':ERC20$'],
  spacing: 2
}

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.

ABIs files are saved in the format [CONTRACT_NAME].json.
