### Live Reload
In development mode (`NODE_ENV !== 'production'`), `hype` automatically injects a live reload script into pages using the default layout. When the server restarts (e.g. via `bun --hot`), the browser will automatically reload the page.
If you're using a custom layout, you can add live reload by importing and rendering the `ReloadScript` component:
```tsx
import { ReloadScript } from "hype"
export default ({ children, title }: any) => (
<html lang="en">
<head>
<title>{title ?? "hype"}</title>
</head>
<body>
<main>{children}</main>
<ReloadScript />
</body>
</html>
)
```
`ReloadScript` only renders in development mode — it's a no-op in production.
