Test-Driven React 2: eslintignore has been deprecated (page 53)

Hi again! Here’s another change that would update the book for eslint ^8.25.0 (‘flat config’): On page 53, .eslintignore files were deprecated in favor of an ‘ignores’ blob array in the config file.

Resources:

error:

❯ npm run lint

> carousel@0.0.0 lint
> eslint .

(node:13196) ESLintIgnoreWarning: The ".eslintignore" file is no longer supported. Switch to using the "ignores" property in "eslint.config.js": https://eslint.org/docs/latest/use/configure/migration-guide#ignoring-files
(Use `node --trace-warnings ...` to show where the warning was created)

And here is an example implementation, unmodified from the template except for the ignores key:

// eslint.config.js
import js from '@eslint/js'
import globals from 'globals'
import reactHooks from 'eslint-plugin-react-hooks'
import reactRefresh from 'eslint-plugin-react-refresh'
import tseslint from 'typescript-eslint'

export default tseslint.config(
	{
		extends: [js.configs.recommended, ...tseslint.configs.recommended],
		files: ['**/*.{ts,tsx}'],
		languageOptions: {
			ecmaVersion: 2020,
			globals: globals.browser,
		},
		plugins: {
			'react-hooks': reactHooks,
			'react-refresh': reactRefresh,
		},
		ignores: ['dist/'], // <-- here
		rules: {
			...reactHooks.configs.recommended.rules,
			'react-refresh/only-export-components': [
				'warn',
				{ allowConstantExport: true },
			],
		},
	},
)

Thanks again for a great book!

This would be the eslint update for page 55, in order to correctly get the ‘target=“blank”’ error:

import js from '@eslint/js'
import globals from 'globals'
import reactHooks from 'eslint-plugin-react-hooks'
import reactRefresh from 'eslint-plugin-react-refresh'
import tseslint from 'typescript-eslint'
import react from 'eslint-plugin-react'

export default tseslint.config(
	{ ignores: ['dist'] },
	{
		extends: [
			js.configs.recommended,
			...tseslint.configs.recommended,
			react.configs.flat.recommended,
			react.configs.flat["jsx-runtime"]
		],
		files: ['**/*.{ts,tsx}'],
		languageOptions: {
			ecmaVersion: 2020,
			globals: globals.browser,
		},
		plugins: {
			'react-hooks': reactHooks,
			'react-refresh': reactRefresh,
		},
		rules: {
			...reactHooks.configs.recommended.rules,
			'react-refresh/only-export-components': [
				'warn',
				{ allowConstantExport: true },
			],
		},
		ignores: ['dist/']
	},
)
