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 🙏

style-mod

Minimal CSS module shim for generating CSS rules for sets of style -declarations and attaching such a set to a document or shadow root.

Using it would look something like this:

const {StyleModule} = require("style-mod")
const myModule = new StyleModule({
  "#main": {
    fontFamily: "Georgia, 'Nimbus Roman No9 L'",
    margin: "0"
  },
  ".callout": {
    color: "red",
    fontWeight: "bold",
    "&:hover": {color: "orange"}
  }
})
StyleModule.mount(document, myModule)

This code is open source, released under an MIT license.

Documentation

class StyleModule

Style modules encapsulate a set of CSS rules defined from JavaScript. Their definitions are only available in a given DOM root after it has been mounted there with StyleModule.mount.

Style modules should be created once and stored somewhere, as opposed to re-creating them every time you need them. The amount of CSS rules generated for a given DOM root is bounded by the amount of style modules that were used. So to avoid leaking rules, don't create these dynamically, but treat them as one-time allocations.

  • new StyleModule(spec: Object< Style >, options: ?{finish: ?fn(string) → string})
    Create a style module from the given spec.

    When finish is given, it is called on regular (non-@) selectors (after & expansion) to compute the final selector.

  • getRules() → string
    Returns a string containing the module's CSS rules.

  • static newName() → string
    Generate a new unique CSS class name.

  • static mount(root: Document | ShadowRoot, modules: [StyleModule] | StyleModule, options: ?{nonce: ?string})
    Mount the given set of modules in the given DOM root, which ensures that the CSS rules defined by the module are available in that context.

    Rules are only added to the document once per root.

    Rule order will follow the order of the modules, so that rules from modules later in the array take precedence of those from earlier modules. If you call this function multiple times for the same root in a way that changes the order of already mounted modules, the old order will be changed.

    If a Content Security Policy nonce is provided, it is added to the <style> tag generated by the library.

Where the Style type is defined as:

  • Style: Object< Style | string >
    A style is an object that, in the simple case, maps CSS property names to strings holding their values, as in {color: "red", fontWeight: "bold"}. The property names can be given in camel-case—the library will insert a dash before capital letters when converting them to CSS.

    If you include an underscore in a property name, it and everything after it will be removed from the output, which can be useful when providing a property multiple times, for browser compatibility reasons.

    A property in a style object can also be a sub-selector, which extends the current context to add a pseudo-selector or a child selector. Such a property should contain a & character, which will be replaced by the current selector. For example {"&:before": {content: '"hi"'}}. Sub-selectors and regular properties can freely be mixed in a given object. Any property containing a & is assumed to be a sub-selector.

    Finally, a property can specify an @-block to be wrapped around the styles defined inside the object that's the property's value. For example to create a media query you can do {"@media screen and (min-width: 400px)": {...}}.
