🌹 @sharyn/eslint-config

You can use this package as a standalone, but I recommend following the development setup tutorial to also install Babel, Flow, Jest, React, and their ESLint-related plugins.

🌹 Install

Minimal install:

yarn add --dev @sharyn/eslint-config eslint

Add to your package.json:

"eslintConfig": {
  "extends": "@sharyn"
},

🌹 Auto-configured Modules

The following supported modules are automatically configured for ESLint if they are detected in your package.json:

• @babel/plugin-proposal-do-expressions – To use do { } expressions
• @babel/plugin-proposal-nullish-coalescing-operator – To use isUndef ?? 'default'
• @babel/plugin-proposal-optional-chaining – To use isUndef?.property
• @babel/plugin-proposal-pipeline-operator – To use 'hello' |> console.log
• babel-eslint – Used to parse Flow and the new Babel syntax proposals
• eslint-config-airbnb – ESLint configuration by Airbnb (with React rules)
• eslint-config-airbnb-base – ESLint configuration by Airbnb (without React rules)
• eslint-config-prettier – Disables ESLint rules conflicting with Prettier
• eslint-import-resolver-babel-module@5.0.0-beta.0 – For ESLint to use babel-plugin-module-resolver
• eslint-plugin-import – Add support for import syntax to ESLint, and import rules
• eslint-plugin-jsx-a11y – ESLint rules for JSX and accessibility
• eslint-plugin-react – ESLint rules for React
• eslint-plugin-flowtype – ESLint rules for Flow annotations
• eslint-plugin-prettier – Show Prettier errors in ESLint
• flow-bin – Flow (type checker) core library and CLI
• jest – Jest (test runner) core library and CLI
• jest-puppeteer – Jest preset for Puppeteer
• react – React and JSX core
