🍑MUI Theme

MUI offers a comprehensive suite of UI tools to help you ship new features faster.

Overview

MUI (short for Material-UI) is a popular open-source library of React components that follows the principles and design guidelines of Google's Material Design system. MUI provides a set of pre-built, customizable UI components such as buttons, forms, cards, and more, that help developers quickly build high-quality, responsive user interfaces for web applications.

How to use

Here we use MUI. The installation method is as follows below.

The official MUI documentation

Step 1: Install MUI dependencies

To use MUI in your app, you need to install the following dependencies:

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

@mui/material: This is the main MUI package that contains all the components and styles.
@emotion/react and @emotion/styled: These are Emotion libraries that are used by MUI for styling.

Step 2: Create a `_document.tsx` file

The _document.tsx file is used to customize the HTML document that is served to the client. To use MUI in your app, you need to add the MUI CSS baseline to the document. Here's how you can create a _document.tsx file:

Create a new file called _document.tsx in the pages directory.
Add the following code to the file:

import Document, { Html, Head, Main, NextScript } from 'next/document';
import { ServerStyleSheets } from '@mui/styles';

export default class MyDocument extends Document {
  render() {
    return (
      <Html lang="en">
        <Head>
          {/* Import the MUI CSS baseline */}
          <link
            rel="stylesheet"
            href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700&display=swap"
          />
        </Head>
        <body>
          <Main />
          <NextScript />
        </body>
      </Html>
    );
  }
}

MyDocument.getInitialProps = async (ctx) => {
  // Render the app and get the context of the page with collected side effects.
  const sheets = new ServerStyleSheets();
  const originalRenderPage = ctx.renderPage;

  ctx.renderPage = () =>
    originalRenderPage({
      enhanceApp: (App) => (props) =>
        sheets.collect(<App {...props} />),
    });

  const initialProps = await Document.getInitialProps(ctx);

  return {
    ...initialProps,
    // Styles fragment is rendered after the app and page rendering finish.
    styles: [...React.Children.toArray(initialProps.styles), sheets.getStyleElement()],
  };
};

This code does the following:

Imports the necessary modules for creating a custom document.
Defines a MyDocument class that extends Document.
Overrides the render method of the MyDocument class to customize the HTML document.
Adds the MUI CSS baseline to the Head section of the document.
Sets up server-side rendering of MUI styles using ServerStyleSheets and getInitialProps.

Step 3: Use the `ThemeProvider` component in `_app.tsx`

You'll need to import and use the ThemeProvider component from MUI in your _app.tsx file.

To do this, open up your _app.tsx file in the pages directory and add the following code:

import { ThemeProvider } from '@mui/material/styles';
import { CssBaseline } from '@mui/material';

function MyApp({ Component, pageProps }: AppProps) {
  return (
    <ThemeProvider theme={/* your MUI theme */}>
      <CssBaseline />
      <Component {...pageProps} />
    </ThemeProvider>
  );
}

export default MyApp;

This code imports the ThemeProvider component and the CssBaseline component from MUI and uses them to wrap your app component. The ThemeProvider component is used to apply your MUI theme to your app, and the CssBaseline component is used to apply a baseline CSS style to your app.

Note: In order to use the ThemeProvider component, you'll need to define and create your own MUI theme. You can create your theme in a separate file and import it into your _app.tsx file.

Step 4: Import MUI components and start using them in your app

With MUI installed and your ThemeProvider set up, you can start using MUI components in your app.

To use MUI components, simply import them from the @mui/material package and use them in your app. For example:

import { Button } from '@mui/material';

function Home() {
  return (
    <div>
      <Button variant="contained" color="primary">
        Hello World
      </Button>
    </div>
  );
}

export default Home;

This code imports the Button component from MUI and uses it in a Home component.
