⚙️ Configs

Stack	Config	Description
	javascript	Default config, suitable for any JavaScript/TypeScript project.
	typescript	Config for strict TypeScript projects.
	node	Config for Node.js projects.
	angular	Config for Angular projects.
	ngrx	Config for Angular projects using NgRx library.
	react	Config for React projects.
	graphql	Config for GraphQL servers implemented in Node.js.
	jest	Config for projects using Jest for testing.
	vitest	Config for projects using Vitest for testing.
	cypress	Config for projects using Cypress for testing.
	playwright	Config for projects using Playwright for testing.
	storybook	Config for projects using Storybook for UI components.
	react-testing-library	Config for projects using React Testing Library for testing.

Some configs extend other configs, as illustrated below. So, for example, extending angular config implicitly extends typescript and javascript configs as well.

  graph BT;
    typescript --extends--> javascript
    node --extends--> javascript
    angular --extends--> typescript
    ngrx --extends--> angular
    react --extends--> javascript
    graphql --extends--> node

🏗️ Setup

To use the default config, follow these steps:

1. You must first install all the required peer dependencies (if you haven't already):

   npm install -D eslint @eslint/js eslint-plugin-{functional,import,promise,sonarjs,unicorn} globals typescript-eslint

2. Install @code-pushup/eslint-config with:

   npm install -D @code-pushup/eslint-config

3. Include default config in your ESLint configuration file (usually eslint.config.js):

   import javascript from '@code-pushup/eslint-config/javascript.js';
   import tseslint from 'typescript-eslint';
   
   export default tseslint.config(...javascript);

Depending on your tech stack, you may wish to extend other configs as well (listed above). This will require installing additional peer dependencies. For more details, refer to setup docs for the configs you're interested in using.
