Configuring ESLint and Prettier in Atom

Install eslint and optional plugins:

npm install -g eslint eslint-plugin-react

Install atom plugins:


Create .eslintrc either in the root of your application (or your root path if you want it to be global)

Add simple configuration rules:

    "plugins": [
    "parserOptions": {
        "ecmaVersion": 6,
        "sourceType": "module",
        "ecmaFeatures": {
            "jsx": true
    "env": {
        "es6":     true,
        "browser": true,
        "node":    true,
        "mocha":   true
    "extends": [
    "rules": {

Optionally, update atom prettier-atom to format on save (in plugin settings)
