eslint-output

library4.0.2jsnpmunverified

A wrapper around ESLint that exports multiple report formats (e.g., stylish, junit, gitlab) in a single run. v4.0.2 supports ESLint >=9 with Flat Config only. Configure via eslintoutput.config.js and CLI overrides. Releases are infrequent, with major version bumps tied to ESLint peer dep changes. Differentiator: eliminates need for multiple lint runs to get different formatters.

Verified usage

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

default (no named export)

✓ npm install --save-dev eslint-output

✗ import eslintOutput from 'eslint-output'

eslint-output is a CLI tool, not a library. Do not import it in code.

eslint-output (CLI command)

✓ npx eslint-output

✗ require('eslint-output')

Use as a script in package.json, not required programmatically.

ESLint config

✓ const config = require('./eslintoutput.config.js')

✗ import config from './eslintoutput.config.js'

Config file uses CommonJS (module.exports). ESLint config itself may be ESM.

Basic configuration with two formatters: console output and file output.

// eslintoutput.config.js module.exports = { files: ['.'], formats: [ { name: 'stylish', output: 'console' }, { name: 'junit', output: 'file', path: 'tmp/junit.xml' } ] }; // package.json "scripts": { "lint": "eslint-output" } // Run npm run lint

eslint-output --version
