// uno.config.js
import { defineConfig } from 'unocss'
import transformerCompileClass from '@unocss/transformer-compile-class'

export default defineConfig({
  // ...
  transformers: [
    transformerCompileClass(),
  ],
})

Usage

At the begin of your class strings, add :uno: at the begin of the strings to mark them for compilation. For example:

<div class=":uno: text-center sm:text-left">
  <div class=":uno: text-sm font-bold hover:text-red"/>
</div>

Will be compiled to:

<div class="uno-qlmcrp">
  <div class="uno-0qw2gr"/>
</div>

.uno-qlmcrp {
  text-align: center;
}
.uno-0qw2gr {
  font-size: 0.875rem;
  line-height: 1.25rem;
  font-weight: 700;
}
.uno-0qw2gr:hover {
  --un-text-opacity: 1;
  color: rgba(248, 113, 113, var(--un-text-opacity));
}
@media (min-width: 640px) {
  .uno-qlmcrp {
    text-align: left;
  }
}

You can config the trigger string and prefix for compile class with the options. Refers to the types for details.
