# hardhat-errors

> ⚠️ This package is an internal Hardhat component and it's not meant to be used directly.

This packages has the definition of the error classes used by Hardhat, and the list of possible errors.

This module exports:

1. The error class `HardhatError`, which has a static field `ERRORS`, with the different `ErrorDescriptors` that it accepts.
2. The error class `HardhatPluginError`, which is the recommended way to handle errors in Hardhat plugins. For convenience, it is re-exported from `@nomicfoundation/hardhat/plugins`. Plugin developers should import it from this path.
3. The interface `ErrorDescriptor`.
4. The assertion helper `assertHardhatInvariant`.
