@noaignite-dk/eslint-config

Provides extensible base eslint configuration. There are 4 variants;

• JavaScript
• TypeScript
• React + TypeScript
• Next.js
• Import

Installation

npm install @noaignite-dk/eslint-config --save-dev

or

yarn add @noaignite-dk/eslint-config --dev

@noaignite-dk/eslint-config

Use this configuration if your project uses JavaScript.

Usage

In your project's .eslintrc.js, add the following:

/** @type {import('eslint').Linter.Config} */
module.exports = {
	extends: ['@noaignite-dk/eslint-config'],
};

@noaignite-dk/eslint-config/typescript

Use this configuration if your project uses TypeScript.

Usage

Create an eslint specific tsconfig file (tsconfig.eslint.json) with the following contents:

{
	"extends": "./tsconfig.json",
	"compilerOptions": {
		"allowJs": true,
		"checkJs": false,
	},
	"include": [
		"**/*.ts",
		"**/*.tsx",
		"**/*.js",
		"**/.*.js",
	],
	"exclude": ["node_modules"]
}

Then, in your project's .eslintrc.js, add the following:

/** @type {import('eslint').Linter.Config} */
module.exports = {
	extends: ['@noaignite-dk/eslint-config/typescript'],
	parserOptions: {
		project: require.resolve('./tsconfig.eslint.json'),
	},
};

@noaignite-dk/eslint-config/react

Use this configuration if your project uses React + Typescript.

Usage

Create an eslint specific tsconfig file (tsconfig.eslint.json) with the following contents:

{
	"extends": "./tsconfig.json",
	"compilerOptions": {
		"allowJs": true,
		"checkJs": false,
	},
	"include": [
		"**/*.ts",
		"**/*.tsx",
		"**/*.js",
		"**/.*.js",
	],
	"exclude": ["node_modules"]
}

Then, in your project's .eslintrc.js, add the following:

/** @type {import('eslint').Linter.Config} */
module.exports = {
	extends: ['@noaignite-dk/eslint-config/react'],
	parserOptions: {
		project: require.resolve('./tsconfig.eslint.json'),
	},
};

@noaignite-dk/eslint-config/next

Use this configuration if your project uses Next.js + Typescript.

Usage

Create an eslint specific tsconfig file (tsconfig.eslint.json) with the following contents:

{
	"extends": "./tsconfig.json",
	"compilerOptions": {
		"allowJs": true,
		"checkJs": false,
	},
	"include": [
		"next-env.d.ts",
		"**/*.ts",
		"**/*.tsx",
		"**/*.js",
		"**/.*.js",
	],
	"exclude": ["node_modules"]
}

Then, in your project's .eslintrc.js, add the following:

/** @type {import('eslint').Linter.Config} */
module.exports = {
	extends: ['@noaignite-dk/eslint-config/next'],
	parserOptions: {
		project: require.resolve('./tsconfig.eslint.json'),
	},
};

If Next.js isn't installed in your root directory (such as a monorepo) rootDir must be configured in .eslintrc.js:

/** @type {import('eslint').Linter.Config} */
module.exports = {
	extends: ['@noaignite-dk/eslint-config/next'],
	settings: {
		next: {
			rootDir: "packages/my-app/"
		},
		'import/resolver': {
			typescript: {
				project: require.resolve('./tsconfig.eslint.json'),
			},
		},
	},
	parserOptions: {
		project: require.resolve('./tsconfig.eslint.json'),
	},
};

@noaignite-dk/eslint-config/import

Use this configuration to add sorting for your project.

Usage

Create an eslint specific tsconfig file (tsconfig.eslint.json) with the following contents:

{
	"extends": "./tsconfig.json",
	"compilerOptions": {
		"allowJs": true,
		"checkJs": false,
	},
	"include": [
		"**/*.ts",
		"**/*.tsx",
		"**/*.js",
		"**/.*.js",
	],
	"exclude": ["node_modules"]
}

Then, in your project's .eslintrc.js, add the following:

/** @type {import('eslint').Linter.Config} */
module.exports = {
	extends: ['@noaignite-dk/eslint-config/import'],
};

Common errors

1. Unable to resolve path to module '@alias/file'. eslint(import/no-unresolved)

This error typically occurs when eslint-import-resolver-typescript cannot resolve the correct tsconfig.json or a baseUrl is missing.

Resolutions:

1. Make sure a baseUrl is set:

(tsconfig.eslint.json)

{
  "compilerOptions": {
    "baseUrl": "."
  }
}

2. Try explicitly passing the tsconfig to the resolver:

(.eslintrc.js)

module.exports = {
	// [...]
	settings: {
		'import/resolver': {
			typescript: {
				project: require.resolve('./tsconfig.eslint.json'),
			},
		},
	},
	parserOptions: {
		project: require.resolve('./tsconfig.eslint.json'),
	},
};
