Ignore global vars

in dir

.eslintrc

{
  "globals": {
    "React": false,
    "ReactDOM": false
  }
}

in file

/* global $ */

To specify globals using a comment inside of your JavaScript file, use the following format:

/* global var1, var2 */

This defines two global variables, var1 and var2. If you want to optionally specify that these global variables should never be written to (only read), then you can set each with a false flag:

/* global var1:false, var2:false */

Disable rules

in current line

disable special rules in current line

import { AppContainer } from 'react-hot-loader'; // eslint-disable-line import/no-extraneous-dependencies

disable special rules in next line

// eslint-disable-next-line import/no-extraneous-dependencies
import { AppContainer } from 'react-hot-loader';

in current file

To disable rule warnings in an entire file, put a /* eslint-disable */ block comment at the top of the file:

/* eslint-disable no-alert, on-console */

alert('foo');

Disable all rules in current file:

/* eslint-disable */

in dir

.eslintrc

{
  "rules": {
    "no-alert": 0,
    "no-console": 0
  }
}

‘react-hot-loader’ should be listed in the project’s dependencies, not devDependencies. (import/no-extraneous-dependencies)
