Tokens are a single source of truth to name and store Atlassian design decisions.
yarn add @atlaskit/tokensA babel plugin to optimise performance and support fallbacks for Design System tokens.
It replaces any calls to the @atlaskit/tokens token() function with the CSS value the function would return (i.e. var(--token-name) or
variations with fallbacks).
If there’s no fallback, the plugin (optionally) finds the token’s value from the default Atlassian theme, and sets it as the fallback.
If there is a fallback defined in code, it’s inserted into the style (expressions are inserted using template strings).
Add the plugin to your babel configuration:
{
"plugins": ["@atlaskit/tokens/babel-plugin"]
}
Currently the plugin supports one option, shouldUseAutoFallback. When enabled, the plugin will fetch the token's value in the default
Atlassian theme (currently atlassian-light) and use it as the fallback value.
This is useful for cases where tokens are in use, but token definitions aren't present in the top-level page CSS.
