@activescott/eslint-config

This is @activescott's sharable config for ESLint. The default is optimized for TypeScript. It does prettify other files too including JavaScript, Markdown, etc.

Multiple config may be added to this package in the future as described at https://eslint.org/docs/developer-guide/shareable-configs#sharing-multiple-configs

Usage

Step 1: Add the following dependencies to your project:

npm add -D @activescott/eslint-config@3 typescript-eslint@8.19.1 eslint-plugin-prettier@5.2.1 eslint-plugin-jest@28.10.0 @stylistic/eslint-plugin@2.12.1

Step 2: Enter the following to create a eslint.config.js, .prettierrc, and .prettierignore in the root with the right content:

printf 'import config from "@activescott/eslint-config"
export default [...config]
' > eslint.config.js
printf "semi: false\n" > .prettierrc
printf "node_modules/\n/dist/\n/.next/\n.nyc_output/\ncoverage/\n" | tee .prettierignore

Step 3 (optional): Add the following scripts to package.json:

{
  "scripts": {
    "lint": "eslint",
    "lint-fix": "eslint --fix"
  }
}

See https://eslint.org/docs/user-guide/configuring for more information.

Notes

React

extends:
  - ...
  - "plugin:react/recommended"
