What is @unocss/vite?
@unocss/vite is a utility-first CSS framework that integrates with Vite, a build tool for modern web projects. It provides a highly customizable and performant way to handle CSS in your Vite projects, leveraging the power of utility classes and on-demand generation.
What are @unocss/vite's main functionalities?
Utility-First CSS
This feature allows you to use utility-first CSS classes in your project. The code sample shows how to integrate Unocss with a Vite project.
import { defineConfig } from 'vite';
import Unocss from '@unocss/vite';
export default defineConfig({
plugins: [
Unocss(),
],
});
On-Demand Generation
Unocss generates CSS on-demand, meaning only the styles you use in your HTML or JavaScript are included in the final build. The code sample demonstrates how to configure Unocss with a preset for on-demand generation.
import { defineConfig } from 'vite';
import Unocss from '@unocss/vite';
export default defineConfig({
plugins: [
Unocss({
presets: [
require('@unocss/preset-uno'),
],
}),
],
});
Customizable
Unocss is highly customizable, allowing you to define your own utility classes and rules. The code sample shows how to add custom rules for margin and padding.
import { defineConfig } from 'vite';
import Unocss from '@unocss/vite';
export default defineConfig({
plugins: [
Unocss({
rules: [
['m-1', { margin: '0.25rem' }],
['p-1', { padding: '0.25rem' }],
],
}),
],
});
Other packages similar to @unocss/vite
tailwindcss
Tailwind CSS is another utility-first CSS framework that provides a wide range of utility classes out of the box. Unlike Unocss, Tailwind CSS requires a configuration file and a build step to generate the final CSS.
windicss
Windi CSS is a next-generation utility-first CSS framework that is similar to Tailwind CSS but offers faster build times and on-demand generation. It is more similar to Unocss in terms of performance and on-demand capabilities.
twind
Twind is a utility-first CSS-in-JS library that provides the benefits of Tailwind CSS without the need for a build step. It generates styles at runtime, making it more flexible but potentially less performant than Unocss.
