@fieryeagle/eslint-config-react

Common eslint + prettier config for React that comes with most dependencies and a patch package to allow minimal setup in userland.

Why?

Initial setup of linting and formatting get repeated over and over across codebases and teams, wasting alot of time and maintenance with duplicated then diverged configs. This package brings together:

• eslint-config-react-app
• @typescript-eslint/parser
• eslint-plugin-prettier

to reduces package.json clutter from

    "@typescript-eslint/eslint-plugin": "^5",
    "@typescript-eslint/parser": "^5",
    "babel-eslint": "^10.1.0",
    "eslint": "^7.12.0",
    "eslint-config-prettier": "^8.3.0",
    "eslint-config-react-app": "^6.0.0",
    "eslint-plugin-flowtype": "^5.2.0",
    "eslint-plugin-import": "^2.24.2",
    "eslint-plugin-jsx-a11y": "^6.4.1",
    "eslint-plugin-prettier": "^4.0.0",
    "eslint-plugin-react": "^7.26.1",
    "eslint-plugin-react-hooks": "^4.2.0",
    "prettier": "^2.6.2",
    "typescript": "^4.6.4"

to

    "@fieryeagle/eslint-config-react": "^0.0.5",
    "@rushstack/eslint-patch": "^1.1.3",

and simplifies config down to few lines of code (example). This is possible thanks to the workaround provided by @rushstack/eslint-patch

This patch is a workaround for a longstanding ESLint feature request that would allow a shared ESLint config to bring along its own plugins, rather than imposing peer dependencies on every consumer of the config. In a monorepo scenario, this enables your lint setup to be consolidated in a single NPM package. Doing so greatly reduces the copy+pasting and version management for all the other projects that use your standard lint rule set, but don't want to be bothered with the details.

Usage

• add packages yarn add -D @fieryeagle/eslint-config-react @rushstack/eslint-patch
• create .eslintrc.js

require("@rushstack/eslint-patch/modern-module-resolution");
module.exports = {
  extends: ['@fieryeagle/eslint-config-react'],
  parserOptions: { tsconfigRootDir: __dirname }
};

• create .prettier.js

const prettierConfig = require('@fieryeagle/eslint-config-react/.prettierrc');
module.exports = prettierConfig;
