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 🙏

MIT License

This is a broccoli library for processing image files and creating SASS variables with Data URIs in them.

NOTES:

  1. file names must make good SASS variable names. Names like "my awesome image.gif" will not work because of the spaces.
  2. file names don't need the $ prefix.
  3. file names should be unique regardless of folder depth. This script is "dumb" and just uses the file name.
  4. Do a little dance.
  5. Make a little love.
  6. Get down tonight.

Usage

In your Brocfile.js:

var sassImageCompiler = require('broccoli-sass-image-compiler');

var imageTree = sassImageCompiler('/some_dir', {
	inputFiles: [
		'**/*.png', // all png files
		'someFile.svg' // specific svg file
	],

	// specify the output file you want created
	outputFile: '/compiled-images.scss',

	// whether or not to output an icon class
	// defaults to true
	icon: true,

	// whether or not to output width and height variables, required for icon class.
	// defaults to true
	size: true, 

	// name for parent class of icon class output (i.e "icon" in `.icon.image_name`)
	// defaults to "icon"
	iconClass: 'icon'
});

Then in your SASS

@import 'path/to/compiled-images';

.custom-class {
	background-image: url($someFile); // derived from 'someFile.svg'
}

.other-class {
	background-image: url($icon_16x16); // if you had a file named "whatever/icon_16x16.png"
}

Output from this tool includes:

  • $filename : the data URI variable with the base64 encoded image in it.
  • $filename_width : the width of the image
  • $filename_height : the height of the image
  • .icon.filename : classes that, when applied can be used as an icon for the image file. <div class="icon filename"></div>
