ESLint

Set Up

Install ESLint globally
```
$ npm install -g [email protected]
```
Verify ESLint is available globally
```
$ eslint -v
```
The terminal should output version info.
Ensure .eslintrc.json and .eslintignore exist at the root of the local repo holding your code:

When the files are missing, get them from the corresponding Github repo.

Before R3.2, find the files from below branches. Afterwards they should be avaliable and up-to-date on master branch.
Enable ESLint in WebStorm
- Go to Perference > Languages & Frameworks > JavaScript > Code Quality Tools > ESLint
- Select the Enable checkbox
- Set ESLint package to /usr/local/lib/node_modules/eslint/
- Click OK to save

Basic usage

To run ESLint on specific file/directory:

$ eslint <relative/absolute path to the file/directory>

To let ESLint automatically fix some safe-to-fix errors:
```
$ eslint --fix <relative/absolute path to the file/directory>
```
A list of fixable errors can be found here(marked by wrench icon).

To disable some ESLint rule for certain code block/statement, find details from here

/* eslint-disable */
{
  foo();
  bar();
  baz();
}
/* eslint-enable */

alert('foo'); // eslint-disable-line
