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 🙏

JavaScript Semifour-Standard Style

![npm][npm-image] ![downloads][downloads-image]

One Semicolon for the Dark Lord on his dark throne

All the goodness of feross/standard with semicolons and four-space indent

Install

npm install semifour-standard

Rules

Importantly:

  • semicolons
  • four-space indent
  • Check feross/standard for the rest of the rules.

Usage

The easiest way to use JavaScript Semifour-Standard Style to check your code is to install it globally as a Node command line program. To do so, simply run the following command in your terminal (flag -g installs semifour-standard globally on your system, omit it if you want to install in the current working directory):

npm install semifour-standard -g

After you've done that you should be able to use the semifour-standard program. The simplest use case would be checking the style of all JavaScript files in the current working directory:

$ semifour-standard
Error: Use JavaScript Semifour-Standard Style
  lib/torrent.js:950:11: Expected '===' and instead saw '=='.

What you might do if you're clever

  1. Add it to package.json
{
  "name": "my-cool-package",
  "devDependencies": {
    "semifour-standard": "*"
  },
  "scripts": {
    "test": "semifour-standard && node my-normal-tests-littered-with-semicolons.js"
  }
}
  1. Check style automatically when you run npm test
$ npm test
Error: Code style check failed:
  lib/torrent.js:950:11: Expected '===' and instead saw '=='.
  1. Never give style feedback on a pull request again! (unless it's about semicolons)

Custom Parser

To use a custom parser, install it from npm (example: npm install babel-eslint) and add this to your package.json:

{
  "semifour-standard": {
    "parser": "babel-eslint"
  }
}

Vim

Install Syntastic and add these lines to .vimrc:

let g:syntastic_javascript_checkers=['standard']
let g:syntastic_javascript_standard_exec = 'semifour-standard'

For automatic formatting on save, add these two lines to .vimrc:

autocmd bufwritepost *.js silent !semifour-standard % --fix
set autoread

Ignoring files

Just like in standard, The paths node_modules/**, *.min.js, bundle.js, coverage/**, hidden files/folders (beginning with .), and all patterns in a project's root .gitignore file are automatically excluded when looking for .js files to check.

Sometimes you need to ignore additional folders or specific minfied files. To do that, add a semifour-standard.ignore property to package.json:

"semifour-standard": {
  "ignore": [
    "**/out/",
    "/lib/select2/",
    "/lib/ckeditor/",
    "tmp.js"
  ]
}

Make it look snazzy

If you want prettier output, just install the snazzy package and pipe semifour-standard to it:

$ semifour-standard --verbose | snazzy

See feross/standard for more information.
