Fylgja Tokens

Establish a consistent design language across your projects with Fylgja Design Tokens.

This predefined set of tokens eliminates redundant variations in spacing, colors, and other design elements, ensuring a unified structure throughout your codebase.

For projects with specific requirements, Fylgja offers granular imports.

Select only the necessary token categories, such as spacing, and define your own custom color palettes.

Furthermore, Fylgja seamlessly integrates with PostCSS Jit Props, mirroring the functionality of Open Props and other design token systems, for optimized CSS output.

Installation

You can install Fylgja Tokens via npm or other Node-based package managers like pnpm or bun:

npm install @fylgja/tokens

Alternatively, you can use it directly via a CDN:

<link href="https://cdn.jsdelivr.net/npm/@fylgja/tokens/css/index.min.css" rel="stylesheet">

Usage

Once installed, you can import the full package with:

import tokens from "@fylgja/tokens";

or as CSS with:

@import "@fylgja/tokens/css";

Next to this we also offers imports for SCSS, JS and for design systems in a json format.

Each option can be import for all tokens or just the part you need.

Shadow DOM Support

For web components utilizing Shadow DOM, import the .host variants to apply tokens within the host scope:

@import "@fylgja/tokens/aspect-ratio.host";

This enables seamless integration of Fylgja Design Tokens within your custom web components.

PostCSS Jit Props Integration

Leverage PostCSS Jit Props to optimize CSS output by including only the tokens used in your project.

While Fylgja tokens are designed for minimal size, this integration further reduces file sizes, especially when combined with custom tokens.
