@code-pushup/eslint-config

Recommended ESLint presets by Code PushUp.

⚙️ Configs

Configurations are available for different tech stacks.

Stack	Config	Description
	@code-pushup	Default config, suitable for any JavaScript/TypeScript project.
	@code-pushup/eslint-config/typescript	Config for strict TypeScript projects.
	@code-pushup/eslint-config/node	Config for Node.js projects.
	@code-pushup/eslint-config/angular	Config for Angular projects.
	@code-pushup/eslint-config/angular-ngrx	Config for Angular projects using NgRx library.
	@code-pushup/eslint-config/graphql	Config for GraphQL servers implemented in Node.js.
	@code-pushup/eslint-config/jest	Config for projects using Jest for testing.
	@code-pushup/eslint-config/vitest	Config for projects using Vitest for testing.
	@code-pushup/eslint-config/cypress	Config for projects using Cypress for testing.
	@code-pushup/eslint-config/storybook	Config for projects using Storybook for UI components.

Some configs extend other configs, as illustrated below. So, for example, adding "extends": ["@code-pushup/eslint-config/angular"] implicitly includes @code-pushup/eslint-config/typescript and @code-pushup as well.

  graph BT;
    index("@code-pushup")
    typescript("@code-pushup/eslint-config/typescript")
    node("@code-pushup/eslint-config/node")
    angular("@code-pushup/eslint-config/angular")
    angular-ngrx("@code-pushup/eslint-config/angular-ngrx")
    graphql("@code-pushup/eslint-config/graphql")
    typescript --extends--> index
    node --extends--> index
    angular --extends--> typescript
    angular-ngrx --extends--> angular
    graphql --extends--> node

🏗️ Setup

To use the default config, follow these steps:

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

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

Install @code-pushup/eslint-config with:

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

Add default config to extends section in your ESLint configuration file (usually called .eslintrc.json or .eslintrc.js):
```
{
  "extends": ["@code-pushup"]
}
```

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.
