Getting Started

Hashi is open-sourced on GitHub and is available on npm.


It is recommended that you install the library as a package rather than pulling it off of a cdn.

# npm
$ npm install @devprotocol/hashi sass --save

# or yarn
$ yarn add @devprotocol/hashi sass


Here's a quick instantiation example:

@use 'node_modules/@devprotocol/hashi';
@use 'node_modules/@devprotocol/hashi/hs-button';
@use 'node_modules/@devprotocol/hashi/hs-utils';

@include hashi.init() {
// Components
@include hs-button.render();

// Utilities
@include hs-utils.layout();
@include hs-utils.color();
@include hs-utils.shape();
@include hs-utils.typography();

This setup gets the design system initialized, gets the button component styles rendered, and the utility classes ready.

To see more hashi.init() options, visit the initializer API page.


If you don't know how to set up a sass build process in your project, please refer to the project's framework documentation and search for how to use sass inside your framework. Otherwise, we recommend checking out using Gulp as your build tool, and follow this tutorial.

Purging unused CSS

We recommend using Purgecss as your CSS purger. The hashi library also provides a custom configuration for purgecss. To use it, write the following in your purgecss.config.js file.

const purgecss = require('@fullhuman/postcss-purgecss');
const hashi = require('@devprotocol/hashi/config/purgecss');

module.exports = {
plugins: [
* File extensions you want to inspect
* (e.g. .html, .jsx/tsx, .php)
