Based on InuitCSS this framework substitute SASS with plain JavaScript using modules and string literals. It is design to use in conjunction with Web Components

Installation & usage

Install npm package in your project npm i wc-jss

Once installed on your project you can star using styles inside your Web Components like above :

// app.js (web component)
import reset from 'wc-jss/generic/reset';
import {LitElement, html} from '@polymer/lit-element';
class WcApp extends LitElement {
  render() {
      return html`
        <div class="app-bar">Example App</div>

Note: Be aware that you will need a bundler in order to import NPM packages

Custom configuration object

You can customize initial settings params (or plugin settings params) by parsing an object the first time you call the singleton config object JSSConfig.

In order to add custom config , create a file , import JSSConfig, and instanciate JSSConfig with the new config object like:

// wcJssSettings.js
import JSSConfig from 'wc-jss/settings/JSSConfig';
const WCJSS = {
  fontSizeHeading: {
    h1: 180,
    h2: 80,
    h3: 40,
    h4: 20,
    h5: 10,
    h6: 8,

The new JSSConfig object will keep original parameters and will add or override parameters with the new one passed in

Because JSSConfig object is a singleton you need to assure that the first time you get the instance you are parsing the new config object. In order to do this your custom file will be the first file imported on your project, this way any further use of the library will contain the custom JSSConfig.

Now in your main index.js the first import will be this file:

import './wcJssSettings';
import './components/app';
// ...

TODO: Input in Pixels output in any

To make it easier for developers, every measure will be in pixels and the output (TODO) will be parametrize, upon config rules (px, rem, em, %)


We use TDD in our development. To run test:

 npm run test

This will run Jest with a watcher

Demo: Storybook

We use story book to make our demos.

We are keeping two packages.json , one for main app and another one only for storybook this way we are not polluting our main library with unwanted packages only needed for storybook

So the first time you start story book you will nedd to to an extra installation:

cd storybook
npm i

And then each time you want to run the server from storybook directory just do:

# To run server on port 6006 
npm run storybook
# To build the storybook  
npm run build-storybook
