Unified design foundations — design system architecture, tokens, component specs, visual principles, creative vision, figma integration, plus brand design system loader (66 real brands via DESIGN.md). Absorbs design, design-system, design-systems, design-principles, design-router, creative-vision, figma, design-md.
Render, summarize, and present markdown documents and structured content in multiple output modes
Ultra UI skill - combines Google's DESIGN.md spec (machine-readable design tokens) with the ui-ux-pro-max knowledge base (91 styles, 161 palettes, 73 font pairings, 161 products, 104 UX guidelines, 25 chart types). Generates lint-clean DESIGN.md files, validates token references and WCAG contrast, exports Tailwind/DTCG tokens, and diffs design systems version-over-version.

Provide expert guidance on Vite configuration, plugin development, HMR optimization, library mode bundling, and production build tuning. Covers Vite 6.x with Rollup under the hood and ESBuild for dev transforms.
Basic vite.config.ts with TypeScript:
// vite.config.ts
import { defineConfig, loadEnv } from 'vite';
import react from '@vitejs/plugin-react';
import tsconfigPaths from 'vite-tsconfig-paths';
export default defineConfig(({ mode }) => {
const env = loadEnv(mode, process.cwd(), '');
return {
plugins: [react(), tsconfigPaths()],
server: {
port: 3000,
strictPort: true,
proxy: {
'/api': {
target: env.API_URL || 'http://localhost:8080',
changeOrigin: true,
rewrite: (path) => path.replace(/^\/api/, ''),
},
},
},
build: {
target: 'es2022',
: ,
: {
: {
: {
: [, ],
: [],
},
},
},
},
: {
: {
: ,
},
},
};
});
Vite exposes env vars prefixed with VITE_ to client code:
// Only VITE_* vars are exposed to the client
// .env
VITE_API_URL=https://api.example.com
DATABASE_URL=postgres://... // NOT exposed to client
// Usage in code
const apiUrl = import.meta.env.VITE_API_URL;
// Type augmentation
// src/vite-env.d.ts
/// <reference types="vite/client" />
interface ImportMetaEnv {
readonly VITE_API_URL: string;
readonly VITE_APP_TITLE: string;
}
interface ImportMeta {
readonly env: ImportMetaEnv;
}
Custom plugin structure:
// plugins/my-plugin.ts
import type { Plugin, ResolvedConfig } from 'vite';
interface MyPluginOptions {
include?: string[];
transform?: boolean;
}
export function myPlugin(options: MyPluginOptions = {}): Plugin {
let config: ResolvedConfig;
return {
name: 'vite-plugin-my-plugin', // must be unique, prefixed with vite-plugin-
enforce: 'pre', // 'pre' | 'post' — run before/after core plugins
// Called when config is resolved
configResolved(resolvedConfig) {
config = resolvedConfig;
},
// Transform source code
transform(code, id) {
if (!id.endsWith('.tsx')) return null;
// Return transformed code + sourcemap
return {
code: code.replace(/__DEV__/g, String(config.mode === 'development')),
map: null, // provide sourcemap if modifying positions
};
},
// Generate virtual modules
resolveId(id) {
if (id === 'virtual:my-module') return '\0virtual:my-module';
return null;
},
load(id) {
if (id === '\0virtual:my-module') {
return `export const data = ${JSON.stringify(options)};`;
}
return null;
},
// Dev-server middleware
configureServer(server) {
server.middlewares.use('/health', (_req, res) => {
res.end(JSON.stringify({ status: 'ok' }));
});
},
};
}
Plugin hooks execution order:
config — Modify config before resolutionconfigResolved — Read final resolved configconfigureServer — Add dev server middleware (dev only)transformIndexHtml — Transform index.htmlresolveId — Resolve custom module IDsload — Load custom module contenttransform — Transform individual modulesbuildStart / buildEnd — Build lifecycle (Rollup hooks)generateBundle — Modify output bundles (build only)Custom HMR handling:
// In a module that needs custom HMR
if (import.meta.hot) {
import.meta.hot.accept((newModule) => {
if (newModule) {
// Handle the updated module
updateState(newModule.default);
}
});
// Clean up side effects before HMR replacement
import.meta.hot.dispose(() => {
cleanup();
});
// Persist data across HMR updates
import.meta.hot.data.count = (import.meta.hot.data.count ?? 0) + 1;
}
HMR performance tips:
// vite.config.ts
export default defineConfig({
server: {
// Watch specific directories to reduce file system overhead
watch: {
ignored: ['**/node_modules/**', '**/.git/**', '**/dist/**'],
},
// Pre-transform frequently imported deps
warmup: {
clientFiles: ['./src/main.tsx', './src/App.tsx'],
},
},
// Optimize deps pre-bundling
optimizeDeps: {
include: ['react', 'react-dom', 'react-router'],
exclude: ['@my/local-package'], // skip pre-bundling for linked packages
},
});
Build a library for npm distribution:
// vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import dts from 'vite-plugin-dts';
import { resolve } from 'path';
export default defineConfig({
plugins: [
react(),
dts({
insertTypesEntry: true,
rollupTypes: true, // bundle .d.ts files
}),
],
build: {
lib: {
entry: resolve(__dirname, 'src/index.ts'),
name: 'MyLib',
formats: ['es', 'cjs'],
fileName: (format) => `my-lib.${format === 'es' ? 'mjs' : 'cjs'}`,
},
rollupOptions: {
// Externalize deps that shouldn't be bundled
external: ['react', 'react-dom', 'react/jsx-runtime'],
output: {
globals: {
react: 'React',
'react-dom': 'ReactDOM',
},
},
},
sourcemap: true,
minify: false, // let consumers minify
},
});
Corresponding package.json:
{
"name": "my-lib",
"version": "1.0.0",
"type": "module",
"main": "./dist/my-lib.cjs",
"module": "./dist/my-lib.mjs",
"types": "./dist/index.d.ts",
"exports": {
".": {
"import": "./dist/my-lib.mjs",
"require": "./dist/my-lib.cjs",
"types": "./dist/index.d.ts"
}
},
"files": ["dist"],
"peerDependencies": {
"react": "^18.0.0 || ^19.0.0",
"react-dom": "^18.0.0 || ^19.0.0"
}
}
Chunk splitting strategies:
// vite.config.ts
export default defineConfig({
build: {
target: 'es2022',
cssMinify: 'lightningcss',
rollupOptions: {
output: {
manualChunks(id) {
// Group large vendor libraries
if (id.includes('node_modules')) {
if (id.includes('react') || id.includes('react-dom')) return 'vendor-react';
if (id.includes('@tanstack')) return 'vendor-tanstack';
if (id.includes('date-fns')) return 'vendor-date';
return 'vendor'; // catch-all for smaller deps
}
},
},
},
// Report compressed sizes
reportCompressedSize: true,
// Increase warning threshold
chunkSizeWarningLimit: 500,
},
});
CSS optimization:
export default defineConfig({
css: {
modules: {
localsConvention: 'camelCaseOnly',
},
preprocessorOptions: {
scss: {
additionalData: `@use "@/styles/variables" as *;`,
},
},
devSourcemap: true,
},
});
// vite.config.ts
import { resolve } from 'path';
export default defineConfig({
build: {
rollupOptions: {
input: {
main: resolve(__dirname, 'index.html'),
admin: resolve(__dirname, 'admin/index.html'),
embed: resolve(__dirname, 'embed/index.html'),
},
},
},
});
defineConfig — Enables type inference without explicit typing.build.target — Match your browser support matrix (default modules).manualChunks for large apps — Split vendor code by update frequency.optimizeDeps.include for faster cold starts.vite-plugin-dts for libraries — Generate proper .d.ts files.server.proxy.loadEnv() in config — Not process.env directly (Vite config runs before env injection).sourcemap in production — Critical for error monitoring (Sentry, etc.).vite preview to test production build before deploying.| Pitfall | Problem | Fix |
|---|---|---|
| CJS dependencies in dev | Slow pre-bundling, warnings | Add to optimizeDeps.include |
process.env in client code | Undefined — Vite uses import.meta.env | Use import.meta.env.VITE_* or define in define config |
| Large vendor bundle | Single chunk for all node_modules | Use manualChunks to split vendors |
Missing type: "module" in package.json | ESM/CJS confusion | Set "type": "module" for ESM projects |
| Plugin order issues | Transforms run in wrong order | Use enforce: 'pre' or 'post' on plugins |
| HMR not working for non-React | Custom modules not hot-reloaded | Implement import.meta.hot.accept() |
