Validate files with XO

Issues regarding rules should be reported on the ESLint issue tracker as it's the actual linter.

$ npm install --save-dev gulp-xo

const gulp = require('gulp');
const xo = require('gulp-xo');

exports.default = () => (
	gulp.src('src/app.js')
		.pipe(xo())
		.pipe(xo.format())
		.pipe(xo.failAfterError())
);

Type: object

Type: boolean

This option instructs ESLint to try to fix as many issues as possible. The fixes are applied to the gulp stream. The fixed content can be saved to file using gulp.dest (See example/fix.js). Rules that are fixable can be found in ESLint's rules list.

When fixes are applied, a "fixed" property is set to true on the fixed file's ESLint result.

Type: boolean
Default: false

Report errors only.
