hardhat-prettier

Hardhat plugin integrating Prettier Solidity for automatic code formatting and style checking. Current stable version 0.0.1 (pre-release) with no regular release cadence — it's experimental. Key differentiators: adds a format task and overrides the check task for Solidity files, leveraging prettier-plugin-solidity's Solidity-specific formatting rules. Minimal configuration via .prettierrc. Requires Hardhat ^2.0.0, Prettier ^2.1.0, and prettier-plugin-solidity 1.0.0-beta.1. Alternatives like solhint focus on linting; this plugin focuses solely on formatting. Active development on GitHub by a single maintainer.
