TailwindCSS support can be added by installing the @roots/bud-tailwindcss extension.


yarn add @roots/bud-tailwindcss --dev --dev

Using tailwind values in JS files

bud.js can be configured to allow for you to import tailwind theme values using the (virtual) @tailwind/* alias.

An example:

import {black} from '@tailwind/colors'
import {sans} from '@tailwind/fontFamily'

export const main = () => { = black = sans

Generating the imports can be memory intensive and increase build times, so it is opt-in.


Better to generate imports only for specific keys (much less memory intensive):

bud.tailwind.generateImports([`colors`, `fontFamily`])

This is a lot better than trying to import the actual tailwind.config.js file to read these values as the values are fully resolved (merged with defaultTheme, plugins applied, etc.)

And it's a lot better than importing tailwindcss/resolveConfig and doing it in the app code because of transitive dependencies.

Lastly, it's better than pre-compiling a static json file because these values are tree-shakeable. The entire generated json for the default tailwind config is ~100kb. The above example adds ~5kb to the overall bundle (and only because tailwind has so many default colors). If you use terser (bud.minify) the difference is entirely negligible.

If you don't import from @tailwind/* nothing is added to the bundle (even if the imports are generated)
