eslint-formatter-jslint-xml

library9.0.1jsnpmunverified

Standalone ESLint formatter that outputs JSLint-compatible XML for integration with CI/CD pipelines or Jenkins. Current stable version is 9.0.1, maintained by Fregante. This package is part of a collection of standalone ESLint formatters, offering lightweight extraction without depending on ESLint's full packages. No release cadence specified; library is released alongside ESLint major versions. Differentiators: zero dependencies, ships TypeScript types, supports Node 18+. Works exclusively with ESLint >=9 (flat config only).

Verified usage

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

eslintFormatterJslintXml

✓ import eslintFormatterJslintXml from 'eslint-formatter-jslint-xml'

✗ import { eslintFormatterJslintXml } from 'eslint-formatter-jslint-xml'

The module exports a default function; named export does not exist.

eslintFormatterJslintXml

✓ const eslintFormatterJslintXml = require('eslint-formatter-jslint-xml')

CJS require is allowed but deprecated; prefer ESM imports.

type FormatterFunction

✓ import type { FormatterFunction } from 'eslint-formatter-jslint-xml'

✗ import { FormatterFunction } from 'eslint-formatter-jslint-xml'

TypeScript users: type-only export. Not available in CJS.

Demonstrates using the formatter with ESLint's flat config (ESLint >=9). Lints files and outputs JSLint XML.

import eslintFormatterJslintXml from 'eslint-formatter-jslint-xml'; import { ESLint } from 'eslint'; const eslint = new ESLint(); const results = await eslint.lintFiles(['src/**/*.js']); const xml = eslintFormatterJslintXml(results, results[0]?.filePath); console.log(xml);

Debug

Known issues

breakingESLint flat config required: ".eslintrc.*" files are ignored in ESLint 9+. Use eslint.config.js.

fix

Create eslint.config.js (or .mjs/.cjs) and ensure eslint >=9.

affects: >=9

deprecatedCommonJS require() is deprecated for this package. Prefer ESM import.

fix

Use 'import eslintFormatterJslintXml from \'eslint-formatter-jslint-xml\'' in ESM context.

affects: >=9

gotchaSecond argument to formatter is the file path, not options. Passing wrong type may produce empty <file> elements.

fix

Ensure second argument is a string (file path) or undefined. For results from multiple files, pass the results array directly and don't pass a second argument for aggregated output.

affects: >=9

gotchaOutput XML may contain fatal errors with missing 'line' or 'char' attributes. Some parsers may reject this.

fix

Handle XML parsing carefully; expect optional attributes on <issue> for fatal errors.

affects: >=9

gotchaFormatter does not escape XML special characters in reason/evidence fields. This can produce invalid XML if lint messages contain <>&.

fix

Sanitize lint messages manually if needed. The issue is present in upstream ESLint as well.

affects: >=8

Errors

Common errors & fixes

Error: Cannot find module 'eslint-formatter-jslint-xml'

Package not installed or not in node_modules path.

fix

Install package: npm install eslint-formatter-jslint-xml

TypeError: eslintFormatterJslintXml is not a function

Incorrect import: using named import instead of default import.

fix

Use: import eslintFormatterJslintXml from 'eslint-formatter-jslint-xml'

Error: This formatter requires ESLint 9+ with flat config

ESLint version <9 or using legacy config (.eslintrc).

fix

Upgrade to eslint@^9 and create eslint.config.js.

SyntaxError: Unexpected token 'export'

Trying to require() the package in a CommonJS context without transpilation.

fix

Use dynamic import: const eslintFormatterJslintXml = (await import('eslint-formatter-jslint-xml')).default; or switch to ESM.
