+## Frontend
+
+Use HTML imports with `Bun.serve()`. Don't use `vite`. HTML imports fully support React, CSS, Tailwind.
+
+Server:
+
+```ts#index.ts
+import index from "./index.html"
+
+Bun.serve({
+  routes: {
+    "/": index,
+    "/api/users/:id": {
+      GET: (req) => {
+        return new Response(JSON.stringify({ id: req.params.id }));
+      },
+    },
+  },
+  // optional websocket support
+  websocket: {
+    open: (ws) => {
+      ws.send("Hello, world!");
+    },
+    message: (ws, message) => {
+      ws.send(message);
+    },
+    close: (ws) => {
+      // handle close
+    }
+  },
+  development: {
+    hmr: true,
+    console: true,
+  }
+})
+```
+
+HTML files can import .tsx, .jsx or .js files directly and Bun's bundler will transpile & bundle automatically. `<link>` tags can point to stylesheets and Bun's CSS bundler will bundle.
+
+```html#index.html
+<html>
+  <body>
+    <h1>Hello, world!</h1>
+    <script type="module" src="./frontend.tsx"></script>
+  </body>
+</html>
+```
+
+With the following `frontend.tsx`:
+
+```tsx#frontend.tsx
+import React from "react";
+import { createRoot } from "react-dom/client";
+
+// import .css files directly and it works
+import './index.css';
+
+const root = createRoot(document.body);
+
+export default function Frontend() {
+  return <h1>Hello, world!</h1>;
+}
+
+root.render(<Frontend />);
+```
+
+Then, run index.ts
+
+```sh
+bun --hot ./index.ts
+```
