eslint-config-babel

library9.0.0jsnpmunverified

ESLint configuration preset for Babel's own codebase. Version 9.0.0 last updated 2021. Not actively maintained; the Babel team now uses @babel/eslint-plugin. This config enforces strict formatting and is primarily intended for internal Babel projects, not general use. Requires babel-eslint and eslint-plugin-flowtype as peer dependencies. Replaced by @babel/eslint-config in Babel 7.12+.

Verified usage

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

default config

✓ module.exports = { extends: ['babel'] }

✗ module.exports = { extends: ['eslint-config-babel'] }

When using extends in .eslintrc, you can omit the 'eslint-config-' prefix.

babel (ESM)

✓ import babel from 'eslint-config-babel'; export default { extends: ['babel'] }

✗ import { babel } from 'eslint-config-babel'

This package does not export a named member; it's a default export object.

require (CommonJS)

✓ const babel = require('eslint-config-babel'); module.exports = { extends: ['babel'] }

✗ const { babel } = require('eslint-config-babel')

CommonJS usage requires default import.

Basic ESLint configuration using eslint-config-babel for a Node.js project with Flowtype support.

// .eslintrc.js module.exports = { extends: ['babel'], parserOptions: { ecmaFeatures: { jsx: true }, }, env: { es6: true, node: true, }, plugins: ['flowtype'], rules: { 'flowtype/define-flow-type': 'warn', }, };
