@usemotif/compiler-swc

Unplugin for Vite, Rollup, Webpack, esbuild, rspack, and farm. Statically extracts motif-js style props at build time.

Install

yarn add -D @usemotif/compiler-swc

Vite

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react-swc';
import motifExtract from '@usemotif/compiler-swc';

export default defineConfig({
  plugins: [motifExtract.vite(), react()],
});

Then add one import in your entry (root layout, main.tsx, etc.) so the bundler chunks the extracted CSS into a real asset:

import 'virtual:motif-extract.css';

Without that import the JSX rewrite still happens, but the resulting CSS has no asset to land in — styles fall back to motif's runtime path. With it, Vite chunks and hashes the CSS, and frameworks like React Router / Next inject the <link rel="stylesheet"> automatically.

Rollup, Webpack, esbuild, rspack, and farm consume the same motifExtract instance — call the matching method (.rollup(), .webpack(), …) per the unplugin convention. The virtual:motif-extract.css import works in all of them.

What it does

Walks every JSX call to a motif-js primitive, resolves literal-arg style props against the active theme at build time, and rewrites the call site so the runtime resolver can short-circuit. The result: atomic CSS classes (web) or hoisted StyleSheet.create ids (React Native, via @usemotif/compiler-metro) replace the per-render resolver work.
