# Buidler ABI Exporter

Export Solidity contract ABIs on compilation via Buidler.

# Installation

yarn add --dev buidler-abi-exporter

# Usage

Load plugin in Buidler config:


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.

# TypeScript Support

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