Buidler ABI Exporter

Export Solidity contract ABIs on compilation via Buidler.

Installation

yarn add --dev buidler-abi-exporter

Load plugin in Buidler config:

usePlugin('buidler-abi-exporter');

Add configuration under the abiExporter key:

option	description	default
`path`	path to ABI export directory (relative to Buidler root)	`'./abi'`
`only`	`Array` of contracts to include (case sensitive), defaults to all contracts if `length` is 0	`[]`
`except`	`Array` of contracts to exclude (case sensitive)	`[]`
`clear`	whether to delete old files in `path` on	`false`

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

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.

For TypeScript compatibility, add 'node_modules/buidler-abi-exporter/type-extensions.d.ts' to the files array in tsconfig.json.
