tailwind-apply is a simple combination of plugins for TailwindCSS and PostCSS. It is intended to provide a basic mechanism and structure for you to easily "apply-your-own-theme" for TailwindCSS.
It does this by extending TailwindCSS's config the same way as @tailwindcss/typography or @tailwindcss/forms, with one critical difference - you can author custom classes in CSS/SCSS/Sass/Less and even use @apply!
You could always extract classes with @apply but this doesn't integrate directly with the TailwindCSS theme, and you soon run into issues using imports and @layer directives due to the nature of the JIT engine.
This plugin is not intended to replace component partials or use of TailwindCSS classes. The same premature abstraction caveats apply 😎
require the PostCSS plugin and point it to the folder containing your custom styles. This instructs PostCSS to treat the files in the styles folder as dependencies and rebuild your CSS on any changes.
// postcss.config.js
module.exports = {
plugins: [
require('tailwind-apply/postcss'), // MUST come before the `tailwindcss` plugin
require('tailwindcss'),
require('autoprefixer'),
],
}require the TailwindCSS plugin and point it to the folder containing your custom styles. This instructs TailwindCSS to extends its theme with the files in the styles folder.
// tailwind.config.js
module.exports = {
content: ['./src/**/*.{js,ts,jsx,tsx}'],
plugins: [require('tailwind-apply')],
}styles
Default: ./styles
Set the root folder where your custom styles are located.
pattern
Default: **/*.{css,scss,sass,less}
Set the glob pattern of the files in the styles folder.
Custom styles authored in CSS files must be arranged into sub-folders named after the layer they target:
basecomponentsutilities
Files outside of these folders won't be added to your TailwindCSS theme, but could be utilised to break down your CSS modules or define CSS variables available across the rest of your theme.

TailwindCSS plugins authored in JS can be located anywhere within your project folders since how they get imported into tailwind.config.js is up to you.
// postcss.config.js
module.exports = {
plugins: [
require('tailwind-apply/postcss')({
styles: './src/theme', // Your styles are located in the `src/theme` folder
pattern: '**/*.sass', // Your styles are authored in Sass only
}),
],
}// tailwind.config.js
module.exports = {
plugins: [
require('tailwind-apply')({
styles: './src/theme', // Your styles are located in the `src/theme` folder
pattern: '**/*.sass', // Your styles are authored in Sass only
}),
],
}
