Hardhat ABI Generator

Export Solidity smart contract ABIs and generate javascript objects on compilation via Hardhat.

yarn add --dev @symblox/hardhat-abi-gen

Load plugin in Hardhat config:

require('@symblox/hardhat-abi-gen');

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.
