Intellij plugin: AirBnB ESLint w/ React

JetBrains (Idea, Webstorm) settings

File > Settings > Plugins > Browse repositories... > Search: eslint > Install > Restart WebStorm

File > Settings > Languages & Frameworks > JavaScript > Code Quality Tools > ESLint

After that it should work like this:

ESLint config

ESLint doesn't come with a config. You have to create your own or use a preset:

npm install --save-dev eslint-config-airbnb eslint

Then in your .eslintrc

{  "extends": "airbnb"}

You can also selectively disable/modify some rules from preset (0 - disable rule, 1 - warning, 2 - error):

{  'extends': 'airbnb',  'rules': {    'indent': [2, 'tab', { 'SwitchCase': 1, 'VariableDeclarator': 1 }],    'react/prop-types': 0,    'react/jsx-indent-props': [2, 'tab'],  }}

Read: Turning off eslint rule for a specific line.

If you don't want to use airbnb config (most popular javascript style guide) you can create your own. Here is the instruction for react: How to config ESLint for React on Atom Editor.

To create your own preset you have to create npm package named eslint-config-myname and then use 'extends': 'myname', http://eslint.org/docs/developer-guide/shareable-configs

You can use command line to check if eslint works:

./node_modules/.bin/eslint .

You may though exclude some files from eslinting (node_modules are excluded by default) in .eslintignore:

bundle.js

There is also a --fix switch for eslint.

.editorconfig

Good companion for ESLint is editorconfig. Here is an example which works in JetBrains products:

root = true# Unix-style newlines with a newline ending every file[*]end_of_line = lfinsert_final_newline = true# Matches multiple files with brace expansion notation# Set default charset[*.{js,jsx,html,sass}]charset = utf-8indent_style = tabindent_size = 4trim_trailing_whitespace = true# don't use {} for single extension. This won't work: [*.{css}][*.css]indent_style = spaceindent_size = 2

I also have a github repository which already has these files set https://github.com/rofrol/react-starter-kit/
