eslint-stats

library1.0.1jsnpmunverified

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.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

byError

✓ import { byError } from 'eslint-stats'

✗ const byError = require('eslint-stats').byError

Default export is an object; named exports are preferred. CJS require() also works.

byWarning

✓ import { byWarning } from 'eslint-stats'

✗ import { byWarning } from 'eslint-stats/byWarning'

All reporters are exported from the main entry; no need to import from subpaths.

byErrorAndWarning

✓ import { byErrorAndWarning } from 'eslint-stats'

✗ import byErrorAndWarning from 'eslint-stats'

Default import is not defined; use named import.

byFolder

✓ import { byFolder } from 'eslint-stats'

Only available as named export.

Shows how to use eslint-stats byError reporter programmatically with ESLint.

import { byError } from 'eslint-stats'; // Use with ESLint programmatic API import { ESLint } from 'eslint'; const eslint = new ESLint(); const results = await eslint.lintFiles(['src/**/*.js']); const formatter = await eslint.loadFormatter(byError); const output = formatter.format(results); console.log(output);

Debug

Known issues

breakingeslint-stats is not compatible with ESLint >= 8.0.0 due to formatter API changes.

fix

Use built-in formatter or migrate to a maintained alternative.

affects: >=8.0.0

deprecatedThe package has not been updated since 2016 and is effectively abandoned.

fix

Consider using eslint-formatter-stats or other maintained forks.

affects: all

gotchaThe reporters only display rules with errors (or warnings) and ignore others; byError will not show warnings, byWarning will not show errors.

fix

Use byErrorAndWarning if you want both.

affects: all

Errors

Common errors & fixes

Error: Cannot find module 'eslint-stats/byError.js'

Incorrect file path when using with ESLint CLI; the module is not at that path in newer Node resolutions.

fix

Use eslint --format node_modules/eslint-stats/byError.js or better: --format eslint-stats/byError (if module resolves).

TypeError: formatter is not a function

ESLint >= 8 expects formatters to be functions; eslint-stats exports objects.

fix

Use an older version of ESLint (<=7.x) or manually wrap the formatter.

Warning: Rule 'no-console' not found

The package does not include actual ESLint rules; this error occurs if you misconfigure ESLint.

fix

Ensure you have the necessary plugins and rules installed separately.
