# Mantine UI
`@lazarv/react-server` is compatible with [Mantine](https://mantine.dev/), a full-featured React component library. You can use Mantine components in your client components with server-side rendering support, PostCSS configuration for Mantine's styling system, and the `MantineProvider` for theming.
## Installation
Install Mantine and its required PostCSS dependencies:
```sh
pnpm add @mantine/core @mantine/hooks
pnpm add -D postcss postcss-preset-mantine postcss-simple-vars
```
## PostCSS configuration
Mantine requires a PostCSS configuration with the `postcss-preset-mantine` plugin and breakpoint variables:
```js filename="postcss.config.cjs"
module.exports = {
plugins: {
"postcss-preset-mantine": {},
"postcss-simple-vars": {
variables: {
"mantine-breakpoint-xs": "36em",
"mantine-breakpoint-sm": "48em",
"mantine-breakpoint-md": "62em",
"mantine-breakpoint-lg": "75em",
"mantine-breakpoint-xl": "88em",
},
},
},
};
```
## Provider setup
Import the core Mantine styles and wrap your app with `MantineProvider` in your root layout. Include the `ColorSchemeScript` in the `` to prevent a flash of unstyled content:
```tsx filename="src/pages/layout.tsx"
import "@mantine/core/styles.css";
import { ColorSchemeScript, createTheme, MantineProvider } from "@mantine/core";
const theme = createTheme({
/** Put your mantine theme override here */
});
export default function Layout({ children }: { children: React.ReactNode }) {
return (
{children}
);
}
```
## Using components
Mantine components that use React hooks or browser APIs must be used in client components. Create a client component and import the Mantine components you need:
```tsx filename="src/components/Counter.tsx"
"use client";
import { useState } from "react";
import { Button, Group, Text } from "@mantine/core";
export function Counter() {
const [count, setCount] = useState(0);
return (
{count}
);
}
```
Then use the client component from your server component page:
```tsx filename="src/pages/index.tsx"
import { Counter } from "../components/Counter";
export default function HomePage() {
return ;
}
```
## Navigation
To use Mantine's navigation components like `NavLink` with `@lazarv/react-server`'s client-side navigation, pass the runtime's `Link` component via the `component` prop:
```tsx filename="src/components/MainNavigation.tsx"
"use client";
import { NavLink } from "@mantine/core";
import { Link, usePathname } from "@lazarv/react-server/navigation";
export function MainNavigation() {
const pathname = usePathname();
return (
<>
);
}
```
## Extension packages
Mantine offers many extension packages for additional functionality. Import their styles in the pages or layouts where they are used:
```tsx filename="src/pages/dates.tsx"
import "@mantine/dates/styles.css";
import { MyDates } from "../components/MyDates";
export default function DatesPage() {
return ;
}
```
Some commonly used Mantine extensions and their style imports:
| Package | Style import |
|---------|-------------|
| `@mantine/dates` | `@mantine/dates/styles.css` |
| `@mantine/charts` | `@mantine/charts/styles.css` |
| `@mantine/notifications` | `@mantine/notifications/styles.css` |
| `@mantine/code-highlight` | `@mantine/code-highlight/styles.css` |
| `@mantine/carousel` | `@mantine/carousel/styles.css` |
| `@mantine/spotlight` | `@mantine/spotlight/styles.css` |
| `@mantine/nprogress` | `@mantine/nprogress/styles.css` |
| `@mantine/tiptap` | `@mantine/tiptap/styles.css` |
| `@mantine/dropzone` | `@mantine/dropzone/styles.css` |
## Client-only components
Some components (like charts that depend on browser APIs) cannot be server-side rendered. Use `ClientOnly` from `@lazarv/react-server/client` to render them only on the client:
```tsx filename="src/pages/charts.tsx"
import "@mantine/charts/styles.css";
import { ClientOnly } from "@lazarv/react-server/client";
import { MyAreaChart } from "../components/MyAreaChart";
export default function ChartsPage() {
return (
);
}
```
