Description

React is a library. It lets you put components together, but it doesn’t prescribe how to do routing and data fetching.
To build an entire app with React, we recommend a full-stack React framework like Next.js or Remix.

Command line

# create a new project (framework: React, variant: TypeScript)
npm create vite@latest

# install the packages
npm install

# run the project
npm run dev

Basic App

public/index.html 
<body>
    <!-- hosts the React application -->
    <div id="root"></div>
    <script type="module" src="/src/main.tsx"></script>
</body>
src/main.tsx 
import { StrictMode } from 'react'
import { createRoot } from 'react-dom/client'
import { CssBaseline } from '@mui/material';

import './index.css'

createRoot(document.getElementById('root')!).render(
  <StrictMode>
    <CssBaseline />
    <h1>My App</h1>
  </StrictMode>,
)
src/index.css 
body {
  display: flex;
  min-height: 100vh;
}

#root {
  margin: 0 auto;
  padding: 2rem;
  text-align: center;
}

Hooks

State

Allows to store values. 

// items is the variable used to store the items
// setItems is a function to set a new value to items
const [items, setItems] = useState<Item[]>([]);

Effect

Allows to connect a component to an external system. 

useEffect(() => {
  const fetchData = async () => {
    const result = await axios(`${API}?query=react`);
  };
  
  fetchData();
}, []);

Responding to Events

export default function Button() {
  function handleClick() {
    alert('You clicked me!');
  }

  return (
    <button onClick={handleClick}>
      Click me
    </button>
  );
}

Form

EditItemForm.tsx 
import { useState } from 'react';
import { TextField, Button, Box, Typography } from '@mui/material';
import { useParams, useNavigate } from 'react-router-dom';

import SaveIcon from '@mui/icons-material/Save';
import CancelIcon from '@mui/icons-material/Cancel';

export default function EditItemForm() {
    const { id } = useParams<{ id: string }>();
    const navigate = useNavigate();

    const initialData = {
        name: id === "1" ? 'Item 1' : 'Item X',
    };

    const [name, setName] = useState<string>(initialData.name);

    const handleSubmit = (e: React.FormEvent<HTMLFormElement>) => {
        e.preventDefault(); // Prevent the default form submission
        console.log('Updated Data:', { name });
        navigate('/');
    };

    const handleCancel = () => {
        navigate('/'); // Navigate back to the item list without saving changes
    };

    return (
        <Box component="form" onSubmit={handleSubmit} sx={{ mt: 3 }}>
            <Typography variant="h4" gutterBottom>
                Edit Item
            </Typography>
            <TextField
                label="Name"
                variant="outlined"
                fullWidth
                margin="normal"
                value={name}
                onChange={(e) => setName(e.target.value)}
                required
            />
            <Box>
                <Button variant="contained" color="primary" type="submit" startIcon={<SaveIcon />} sx={{ mr: 1 }}>
                    Save
                </Button>
                <Button variant="outlined" color="secondary" onClick={handleCancel} startIcon={<CancelIcon />}>
                    Cancel
                </Button>
            </Box>
        </Box>
    )
}
