eslint-stats

Custom ESLint formatters that aggregate errors by rule rather than by file. Currently at version 1.0.1 (stable, last released 2016). It helps when introducing ESLint to a large codebase by showing which rules cause the most violations. Differentiates from default formatters by providing aggregated views: byError, byWarning, byErrorAndWarning, byErrorAndWarningStacked, and byFolder. No active maintenance; works with ESLint < 8.x due to API changes.
