object-curly-newline counts default export in minProperties #10101

accepted archived due to age bug rule

Tell us about your environment

Ubuntu 17.10

  • ESLint Version: 4.19.0
  • Node Version: 9.6.1
  • npm Version: 5.7.1

(Also validated on OSX, Node 7.10.0, npm 4.2.0)

What parser (default, Babel-ESLint, etc.) are you using?

Default, I believe(?), with sourceType: module. Full configuration:



	"root": true,
	"env": { "es6": true },
	"extends": [
	"parserOptions": {
		"sourceType": "module"
	"rules": {
		"object-curly-newline": [ "error", {
			"minProperties": 2,
			"consistent": true
		} ]

What did you do? Please include the actual source code causing the issue, as well as the command that you used to run ESLint.

This gist contains a reduced test case with the package.json, .eslintrc and test.js as described here; downloading that gist, running npm install and then npm test replicates the issue on every environment I can access.


import DefaultExport, { NamedExport } from 'some-module';
import { NamedExportWithoutDefaultImport } from 'some-other-module';

export default {


  "name": "test-object-curly-newline",
  "scripts": {
    "test": "eslint ./test.js"
  "devDependencies": {
    "eslint": "^4.19.0"
npm test # runs `eslint ./test.js`

What did you expect to happen?

I expected no object-curly-newline issue to be reported for either of these imports, as they both have only a single named export within curly brackets:

import DefaultExport, { NamedExport } from 'some-module';
import { NamedExportWithoutDefaultImport } from 'some-other-module';

however the default export on the first line is being counted as an object property, meaning that the rule matches the minProperties and I get errors for each curly bracket on Line 1, but not Line 2

What actually happened? Please include the actual, raw output from ESLint.

$ npm test

> test-object-curly-newline@ test /hm/gh/coding-standards/packages/eslint-config-humanmade/test
> eslint ./test.js

  1:23  error  Expected a line break after this opening brace   object-curly-newline
  1:37  error  Expected a line break before this closing brace  object-curly-newline

I've confirmed this in our online demo. Setting minProperties: 3 makes the example pass linting, so the proposed explanation is very likely to be correct.

I'll work on this.
