This repository includes configs for popular linting and styling tools, extended from @vercel/style-guide. See Vercel's style guide.

The following configs are available:

• ESLint
• TypeScript
• Prettier
• Stylelint

Installation

All configs are contained in one package, @glasshouse/style-guide. To install:

# If you use npm
npm i --save-dev @glasshouse/style-guide

# If you use pnpm
pnpm i --save-dev @glasshouse/style-guide

# If you use Yarn
yarn add --dev @glasshouse/style-guide

Prettier

Note: Prettier is a peer-dependency of this package, and should be installed at the root of your project. See: Install · Prettier

To use the shared Prettier config, set the following in package.json:

{
  "prettier": "@glasshouse/style-guide/prettier"
}

ESLint

:information_source: ESLint is a peer-dependency of this package, and should be installed at the root of your project.

See: Getting Started with ESLint - ESLint - Pluggable JavaScript Linter

Configuration (new: eslint.config.js)

:warning: BREAKING CHANGE:

• ESLint minimum version is now 9.0.0.
• Refactored configs using new flat config format.
• Moved all configs into a single object default export. You can now import new flat configs by the example below.

import gvseslint from '@glasshouse/style-guide/eslint

export default [
	...gvseslint.configs.flat.node,
]

:information_source: These ESLint configs are based from @vercel/style-guide/eslint

The following configs are available:

• browser
• node
• next (requires @next/eslint-plugin-next to be installed at the same version as next)
• react
• typescript (requires typescript to be installed and additional configuration)

For example, use the shared ESLint config(s) in a Next.js project, set the following in eslint.config.js (or any other ESLint configuration file format):

import gvseslint from '@glasshouse/style-guide/eslint';

/** @type {import('eslint').Linter.Config[]} */
export default [
	...gvseslint.configs.flat.browser,
	...gvseslint.configs.flat.react,
	...gvseslint.configs.flat.typescript,
	...gvseslint.configs.flat.next,
	// ...
];

Configuration (legacy: .eslintrc*)

:warning: This is compatible only with version 0.3.1 or earlier of the package. The latest version (1.0.0) introduces breaking changes, which are not supported.

All configs require typescript to be installed and additional configuration.

The following configs are available:

• @glasshouse/style-guide/eslint/base
• @glasshouse/style-guide/eslint/library
• @glasshouse/style-guide/eslint/react
• @glasshouse/style-guide/eslint/next (requires @next/eslint-plugin-next to be installed at the same version as next)

:information_source: You'll need to use require.resolve to provide ESLint with absolute paths, due to an issue around ESLint config resolution (see eslint/eslint#9188).

For example, use the @glasshouse/style-guide/eslint/next in a Next.js project, set the following in .eslintrc.js (or any other ESLint config file format):

/** @type {import('eslint').Linter.Config} */
module.exports = {
	extends: [require.resolve('@glasshouse/style-guide/eslint/next')],
};

Configuring ESLint (new: eslint.config.js) for TypeScript

Some of the rules enabled in the TypeScript config require additional type information, you'll need to provide the path to your tsconfig.json.

For more information, see: https://typescript-eslint.io/getting-started/typed-linting

export default [
	//...,
	...gvseslint.configs.flat.typescript,
	{
		languageOptions: {
			parserOptions: {
				projectService: true,
				tsconfigRootDir: import.meta.dirname,
			},
		},
	},
];

Configuring ESLint (legacy: .eslintrc*) for TypeScript

const { resolve } = require('node:path');

const project = resolve(__dirname, 'tsconfig.json');

module.exports = {
	root: true,
	extends: [require.resolve('glasshouse/style-guide/eslint/next')],
	parserOptions: {
		project,
	},
	settings: {
		'import/resolver': {
			typescript: {
				project,
			},
		},
	},
};

TypeScript

This style guide provides multiple TypeScript configs for different project types.

To use the shared TypeScript config, set the following in tsconfig.json.

{
	"extends": "@glasshouse/style-guide/typescript/react-library"
}

The base TypeScript config is also available as @glasshouse/style-guide/typescript which only specifies a set of general rules:

{
	"extends": "@glasshouse/style-guide/typescript"
}

Stylelint

:information_source: Stylelint is a peer-dependency of this package, and should be installed at the root of your project.

See: Stylelint

This style guide provides a shared Stylelint config with extended SCSS/SASS linting rules support.

To use this config, set the following in stylelint.config.mjs (or any other Stylelint config file format):

/** @type {import('stylelint').Config} */
export default {
	extends: ['@glasshouse/style-guide/stylelint'],
};
