@pikacss/unplugin-pikacss

PikaCSS bundler integration for the Rollup and Webpack families. Officially supported hosts are Vite, Rollup, Rolldown, Webpack, and Rspack.

PikaCSS requires Node.js >=22.19.0 (package engine range: >=22.19.0). The Vite entry supports Vite 7 and 8 only.

Installation

pnpm add -D @pikacss/unplugin-pikacss

When using the @pikacss/unplugin-pikacss/vite entry, install Vite 7 or 8.

Usage

Vite

// vite.config.ts
import pikacss from '@pikacss/unplugin-pikacss/vite'
import { defineConfig } from 'vite'

export default defineConfig({
  plugins: [pikacss()],
})

Supported bundlers

Use the explicit entry point matching your bundler:

Family	Bundler	Entry point
Rollup	Vite	@pikacss/unplugin-pikacss/vite
Rollup	Rollup	@pikacss/unplugin-pikacss/rollup
Rollup	Rolldown	@pikacss/unplugin-pikacss/rolldown
Webpack	Webpack	@pikacss/unplugin-pikacss/webpack
Webpack	Rspack	@pikacss/unplugin-pikacss/rspack

Other Unplugin hosts, including esbuild, are not supported. No public adapter entry point is shipped for unsupported hosts. The package root exposes shared types and factory primitives; use one of the supported bundler subpaths above for an executable plugin.

For example:

// rollup.config.ts
import pikacss from '@pikacss/unplugin-pikacss/rollup'

export default {
  plugins: [pikacss()],
}

See the integration guide for bundler-specific configuration details.

CLI

Installing this package also provides the pikacss binary:

pikacss init --cwd .
pikacss prepare --cwd .
pikacss prepare --cwd . --config ./config/pika.config.ts

init conservatively creates a canonical config only when one does not already exist. prepare publishes PikaCSS generated authoring state only; it does not scan application sources, build runtime CSS, or emit production reports.
