Garden ESLint Config

:seedling: Garden is the design system by Zendesk

This package exposes a shareable ESLint config and a selection of associated plugins.

Installation

npm install eslint @babel/eslint-parser eslint-plugin-node @zendeskgarden/eslint-config

Usage

Add a .eslintrc.json to your project with an extends property like this:

{
  "extends": "@zendeskgarden"
}

Now Garden linting rules will apply to your project. See the ESLint Documentation for more details on extending shareable configuration files.

Plugins

The following shared plugins are also available.

Jest

Install the following dependency in addition to those listed above.

npm install jest eslint-plugin-jest

Extend the base configuration.

{
  "extends": ["@zendeskgarden", "@zendeskgarden/eslint-config/plugins/jest"]
}

In some cases, it may be useful to limit the scope of the Jest rules via overrides.

{
  "extends": "@zendeskgarden",
  "overrides": [
    {
      "files": ["*.spec.*"],
      "extends": "@zendeskgarden/eslint-config/plugins/jest"
    }
  ]
}

React

The React plugin bundles rules for React, React Hooks, and JSX accessibility. Install the following dependencies in addition to those listed above.

npm install eslint-plugin-react eslint-plugin-react-hooks eslint-plugin-jsx-a11y

Extend the base configuration.

{
  "extends": ["@zendeskgarden", "@zendeskgarden/eslint-config/plugins/react"]
}

TypeScript

Install the following dependencies in addition to those listed above.

npm install typescript @typescript-eslint/parser @typescript-eslint/eslint-plugin

Extend the base configuration.

{
  "extends": [
    "@zendeskgarden",
    "@zendeskgarden/eslint-config/plugins/typescript"
  ]
}

For mixed JS and TS codebases, it may be useful to limit the scope of the TypeScript rules via overrides.

{
  "extends": "@zendeskgarden",
  "overrides": [
    {
      "files": ["*.ts", "*.tsx"],
      "extends": "@zendeskgarden/eslint-config/plugins/typescript"
    }
  ]
}

The typescript plugin covers rules for syntax checking. An additional typescript-semantics plugin provides rules based on semantics. The typescript-semantics plugin requires type information in order to execute. Set parserOptions.project to a valid TSConfig for the project. See typescript-eslint documentation for details.

{
  "extends": [
    "@zendeskgarden",
    "@zendeskgarden/eslint-config/plugins/typescript",
    "@zendeskgarden/eslint-config/plugins/typescript-semantics"
  ],
  "parserOptions": {
    "project": ["./tsconfig.json"]
  }
}
