Introduction

React is an open-source JavaScript library for building user interfaces in WEB and mobile applications. Currently, React is at version 17 and Meta (formerly Facebook) is the main maintainer of the project.

Material UI is a CSS framework with foundational and advanced components, enabling you to develop applications faster.

Prerequisites

Before you start, you need to install and configure the tools:

• git
• Node.js and npm
• IDE (e.g. Visual Studio Code or WebStorm)

Getting started

Create the React application

1. Let's create the application with the React base structure using the create-react-app tool.

npx create-react-app react-mui --template typescript

Creating a new React app in /home/rodrigokamada/Development/React/react-mui.

Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts with cra-template-typescript...

We detected TypeScript in your project (src/App.test.tsx) and created a tsconfig.json file for you.

Your tsconfig.json has been populated with default values.

To address all issues (including breaking changes), run:
  npm audit fix --force

Run `npm audit` for details.

Created git commit.

Success! Created react-mui at /home/rodrigokamada/Development/React/react-mui
Inside that directory, you can run several commands:

  npm start
    Starts the development server.

  npm run build
    Bundles the app into static files for production.

  npm test
    Starts the test runner.

  npm run eject
    Removes this tool and copies build dependencies, configuration files
    and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

  cd react-mui
  npm start

Happy hacking!

2. Install the @mui/material, @mui/icons-material, @mui/lab, @emotion/react, @emotion/styled and @types/date-fns libraries.

npm install @mui/material @mui/icons-material @mui/lab @emotion/react @emotion/styled @types/date-fns

3. Remove the contents of the src/App.tsx file. Add some components as below.

import React from 'react';
import AppBar from '@mui/material/AppBar';
import Avatar from '@mui/material/Avatar';
import Box from '@mui/material/Box';
import Button from '@mui/material/Button';
import Container from '@mui/material/Container';
import FormControlLabel from '@mui/material/FormControlLabel';
import IconButton from '@mui/material/IconButton';
import Menu from '@mui/material/Menu';
import MenuIcon from '@mui/icons-material/Menu';
import MenuItem from '@mui/material/MenuItem';
import Modal from '@mui/material/Modal';
import Switch from '@mui/material/Switch';
import TextField from '@mui/material/TextField';
import Toolbar from '@mui/material/Toolbar';
import Tooltip from '@mui/material/Tooltip';
import Typography from '@mui/material/Typography';
import AdapterDateFns from '@mui/lab/AdapterDateFns';
import DatePicker from '@mui/lab/DatePicker';
import LocalizationProvider from '@mui/lab/LocalizationProvider';
import './App.css';

const pages = ['Products', 'Pricing', 'Blog'];
const settings = ['Profile', 'Account', 'Dashboard', 'Logout'];

const modalStyle = {
  position: 'absolute' as 'absolute',
  top: '50%',
  left: '50%',
  transform: 'translate(-50%, -50%)',
  width: 400,
  bgcolor: 'background.paper',
  border: '2px solid #000',
  boxShadow: 24,
  p: 4,
};

function App() {
  const [anchorElNav, setAnchorElNav] = React.useState<null | HTMLElement>(null);
  const [anchorElUser, setAnchorElUser] = React.useState<null | HTMLElement>(null);

  const handleOpenNavMenu = (event: React.MouseEvent<HTMLElement>) => {
    setAnchorElNav(event.currentTarget);
  };
  const handleOpenUserMenu = (event: React.MouseEvent<HTMLElement>) => {
    setAnchorElUser(event.currentTarget);
  };

  const handleCloseNavMenu = () => {
    setAnchorElNav(null);
  };

  const handleCloseUserMenu = () => {
    setAnchorElUser(null);
  };

  const [value, setValue] = React.useState<Date | null>(null);

  const [open, setOpen] = React.useState(false);
  const handleOpen = () => setOpen(true);
  const handleClose = () => setOpen(false);

5. Ready! Access the URL http://localhost:300/react-mui and check if the application is working. See the application working on GitHub Pages and Stackblitz.

The application repository is available at https://github.com/rodrigokamada/react-mui.
