eslint-formatter-pretty

library7.1.0jsnpmunverified

A pretty formatter for ESLint that provides aesthetically pleasing output with syntax highlighting, clickable hyperlinks for filenames and rule IDs, and severity-sorted results. Version 7.1.0 is the latest stable release, released in 2025, with a cadence of major breaking changes tied to Node.js version bumps. It ships TypeScript types and is maintained by Sindre Sorhus. Key differentiators: stylish output with inline codeblock styling, open-in-editor support for filenames, and rule doc links. Alternatives like `eslint-formatter-codeframe` focus on code frames without the visual polish.

Verified usage

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

default

✓ import eslintFormatterPretty from 'eslint-formatter-pretty';

✗ const eslintFormatterPretty = require('eslint-formatter-pretty');

Since v6, the package is ESM-only. Use import syntax. CommonJS require will not work.

default (CommonJS)

✓ import eslintFormatterPretty from 'eslint-formatter-pretty';

For projects still on ESLint v8, avoid v6+; use v5 with require('eslint-formatter-pretty') instead.

Shows how to use ESLint programmatically with the pretty formatter, including installation and CLI usage.

// Quick start: run ESLint with the pretty formatter // Install: npm install --save-dev eslint eslint-formatter-pretty // Then run: eslint --format=pretty src/ // Example to use programmatically: import eslint from 'eslint'; import eslintFormatterPretty from 'eslint-formatter-pretty'; async function lintAndFormat() { const engine = new eslint.ESLint(); const results = await engine.lintFiles(['src/']); const formatted = eslintFormatterPretty(results); console.log(formatted); } lintAndFormat().catch(console.error);

Debug

Known issues

breakingv6 requires Node.js 18 and ESLint v9+. ESLint v8 users must stick to v5.

fix

If using ESLint <9, install eslint-formatter-pretty@5 instead.

affects: >=6.0.0

breakingv7 drops Node.js 18 support; requires Node.js 20.

fix

Upgrade Node.js to 20 or use v6 which supports Node.js 18.

affects: >=7.0.0

deprecatedv5 is deprecated; it only receives critical security fixes.

fix

Upgrade to v6+ if using ESLint 9+, else stick with v5.

affects: >=5.0.0 <6.0.0

gotchaThe package is ESM-only from v6 onwards; require() will fail.

fix

Use dynamic import() or add 'type': 'module' to package.json.

affects: >=6.0.0

gotchaClickable hyperlinks for filenames and rule IDs only work in terminals with hyperlink support (e.g., iTerm2, VSCode terminal).

fix

Use a compatible terminal or rely on standard text output.
