library9.0.1jsnpmunverified

Standalone ESLint compact formatter package republishing ESLint's built-in compact output format. Version 9.0.1 requires Node.js ^18.18.0 || ^20.9.0 || >=21.1.0. Ships TypeScript declarations. Released infrequently, mirrors ESLint's own formatter. No extra features vs. ESLint's built-in; useful for programmatic usage or when the built-in formatter is not available.

Use the package name when the formatter is from an npm package, not the built-in alias.

Shows how to use the formatter programmatically with ESLint's API, including loading the formatter from the package.

import eslintFormatterCompact from 'eslint-formatter-compact'; import { ESLint } from 'eslint'; const engine = new ESLint(); const results = await engine.lintFiles(['src/']); const formatter = await engine.loadFormatter(eslintFormatterCompact); console.log(formatter.format(results));

Debug

Known issues

breakingThe package now requires Node.js 18+ as of v9.0.0.

fix

Upgrade Node.js to ^18.18.0 || ^20.9.0 || >=21.1.0.

affects: >=9.0.0

breakingRemoved support for CommonJS require() via index.js in v9.0.0; package is now ESM-only.

fix

Use import or dynamic import(). For CommonJS projects, use dynamic import e.g. const formatter = await import('eslint-formatter-compact').then(m => m.default);

affects: >=9.0.0

gotchaThis formatter does not output color/ANSI codes; output is plain text.

fix

For colored output, use the `stylish` formatter instead.

affects: all

gotchaThe formatter expects ESLint's LintResult[] format; using with older ESLint versions may cause errors.

fix

Ensure ESLint version matches the formatter's ESLint peer dependency (check package.json).

affects: >=9.0.0
