Asphalt Web Tokens

Tokens are the building block of our design system and foundation of theming. Asphalt Web Tokens acts as a bridge between components and theming by abstracting the logic of fetching & processing tokens and theme creation. It works as per the theme specification.

This package exports

• legacy tokens as default export.
• variables, theme & getTheme as named exports
  • variables: default tokens in form of CSS variables.
  • theme: default theme in compact format as per theme specification.
  • getTheme: function to get theme in any format for a set of tokens, it accepts tokens & format as parameters.

Theme has three formats -

1. default - theme object with all properties of tokens, also referred as expanded form.
2. compact - theme object with subset of token properties.
3. legacy - object with CSS custom properties and their values.

Maintainers

Extracting tokens

Token Studio uses its sync feature to save the raw tokens into the token.json file within each theme.

Generating themes

1. Open theme-generation.js script inside the scripts folder.

2. Change the import statement import asphaltWebTokens from "../packages/asphalt-web-tokens/src/lib/token.json" assert { type: "json" }; to required theme's token.json.

   For example: import asphaltWebTokens from ../packages/theme-asphalt-web-aloha/token.json { type: "json" }

3. Change the themeName parameter to a relevant name.

   For example: asphalt-web-aloha

4. Run the script using node scripts/theme-generation.js
