Material UI

@lazarv/react-server is compatible with Material UI (MUI), a popular React component library implementing Google's Material Design. MUI uses Emotion for CSS-in-JS styling, which works out of the box with @lazarv/react-server.

Install Material UI and its required dependencies:

pnpm add @mui/material @emotion/react @emotion/styled

Optionally, install the Roboto font and Material Icons:

pnpm add @fontsource/roboto @mui/icons-material

Create a theme file to configure your Material UI theme:

app/theme.mjs
import { createTheme } from "@mui/material/styles"; const theme = createTheme({ palette: { mode: "light", }, typography: { fontFamily: "Roboto", }, }); export default theme;

Material UI requires a ThemeProvider and CssBaseline for proper theming and baseline styles. Create a client component that wraps your app:

app/components/Layout.jsx
"use client"; import Container from "@mui/material/Container"; import CssBaseline from "@mui/material/CssBaseline"; import { ThemeProvider } from "@mui/material/styles"; import theme from "../theme"; export default function Layout({ children }) { return ( <ThemeProvider theme={theme}> <CssBaseline /> <Container maxWidth="lg"> {children} </Container> </ThemeProvider> ); }

Then set up your root layout to import the font and use the Layout provider component:

app/layout.jsx
import "@fontsource/roboto/300.css"; import "@fontsource/roboto/400.css"; import "@fontsource/roboto/500.css"; import "@fontsource/roboto/700.css"; import Layout from "./components/Layout"; export default function RootLayout({ children }) { return ( <html lang="en" suppressHydrationWarning> <head> <meta charSet="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <title>My App</title> </head> <body suppressHydrationWarning> <Layout>{children}</Layout> </body> </html> ); }

To use MUI link and button components with @lazarv/react-server's client-side navigation, pass the runtime's Link component via the component prop:

app/page.jsx
"use client"; import { Link as ReactServerLink } from "@lazarv/react-server/navigation"; import Link from "@mui/material/Link"; export default function Home() { return ( <Link to="/about" color="secondary" component={ReactServerLink}> Go to the about page </Link> ); }

The same pattern works with MUI Button for navigation:

app/about/page.jsx
"use client"; import { Link as ReactServerLink } from "@lazarv/react-server/navigation"; import Button from "@mui/material/Button"; export default function About() { return ( <Button to="/" component={ReactServerLink}> Go to the home page </Button> ); }

Some MUI components that don't rely on browser APIs or React hooks can be used directly in server components. Components like Typography and Link (without navigation) work in server components:

app/components/Copyright.jsx
import Typography from "@mui/material/Typography"; import Link from "@mui/material/Link"; export default function Copyright() { return ( <Typography variant="body2" color="text.secondary" align="center"> {"Copyright © "} <Link color="inherit" href="https://mui.com/"> Your Website </Link>{" "} {new Date().getFullYear()}. </Typography> ); }

When using @mui/icons-material, import icons from the ESM path for proper module resolution:

import LightbulbOutlined from "@mui/icons-material/esm/LightbulbOutlined";
