Usage

ESLint

Create .eslintrc.json file:

JavaScript

{
  "root": true,
  "extends": ["ferfalk"]
}

TypeScript

{
  "root": true,
  "extends": ["ferfalk/typescript"]
}

The TypeScript configuration already extends the JavaScript configuration.

Jest

If Jest is configured, add ferfalk/jest rules:

{
  "extends": ["ferfalk/typescript", "ferfalk/jest"]
}

Works with JavaScript or TypeScript rules.

Prettier

Set your Prettier configuration, for @ferfalk/prettier-config add the prettier property on package.json:

{
  "prettier": "@ferfalk/prettier-config"
}

lint-staged

This project also publishes lint-staged configurations for JavaScript and TypeScript. Create a lint-staged.config.js file:

ESM:

import jsConfig from 'eslint-config-ferfalk/lint-staged-javascript.js';
import tsConfig from 'eslint-config-ferfalk/lint-staged-typescript.js';

export default {
  ...jsConfig,
  ...tsConfig,
};

CommonJS:

const jsConfig = require('eslint-config-ferfalk/lint-staged-javascript.js');
const tsConfig = require('eslint-config-ferfalk/lint-staged-typescript.js');

module.exports = { ...jsConfig, ...tsConfig };
