Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

gulp-xo

v0.26.0

Published

Validate files with XO

Readme

Deprecated. Just use the XO CLI directly.


gulp-xo

Validate files with XO

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

Install

$ npm install --save-dev gulp-xo

Usage

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

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

API

xo(options?)

options

Type: object

Any additional options to the below are passed directly to XO. However, you should prefer setting your XO config in package.json so editors and other tools can also read it. Only pass them here if you want to use options different from those of your current project. You might want to do this if your Gulp task lints or builds files that are/will be part of a separate project.

fix

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.

quiet

Type: boolean
Default: false

Report errors only.

xo.format(formatter, output)

xo.failAfterError()

xo.failOnError()

xo.formatEach(formatter, output)

xo.result(action)

xo.results(action)
