MUI X is an extension of the popular Material-UI (MUI) React component library. It provides advanced and complex components that are not part of the core MUI package, such as data grids, date pickers, and charts. MUI X is designed to enhance the capabilities of MUI for building sophisticated user interfaces.

Pros

• Offers advanced components that integrate seamlessly with the core MUI library
• Provides high-performance data grid component with extensive features
• Includes customizable date and time pickers with various formats and localization options
• Regularly updated and maintained by the MUI team

Cons

• Some components require a paid license for commercial use
• Learning curve can be steep for developers new to MUI ecosystem
• Limited number of advanced components compared to some other UI libraries
• Documentation can be overwhelming due to the complexity of some components

Code Examples

1. Using the Data Grid component:

import { DataGrid } from '@mui/x-data-grid';

const columns = [
  { field: 'id', headerName: 'ID', width: 90 },
  { field: 'firstName', headerName: 'First name', width: 150 },
  { field: 'lastName', headerName: 'Last name', width: 150 },
];

const rows = [
  { id: 1, lastName: 'Snow', firstName: 'Jon' },
  { id: 2, lastName: 'Lannister', firstName: 'Cersei' },
];

function MyDataGrid() {
  return (
    <div style={{ height: 400, width: '100%' }}>
      <DataGrid rows={rows} columns={columns} pageSize={5} checkboxSelection />
    </div>
  );
}

2. Using the Date Picker component:

import { DatePicker } from '@mui/x-date-pickers/DatePicker';
import { AdapterDateFns } from '@mui/x-date-pickers/AdapterDateFns';
import { LocalizationProvider } from '@mui/x-date-pickers/LocalizationProvider';

function MyDatePicker() {
  const [value, setValue] = React.useState(null);

  return (
    <LocalizationProvider dateAdapter={AdapterDateFns}>
      <DatePicker
        label="Basic example"
        value={value}
        onChange={(newValue) => {
          setValue(newValue);
        }}
        renderInput={(params) => <TextField {...params} />}
      />
    </LocalizationProvider>
  );
}

3. Using the TreeView component:

import { TreeView, TreeItem } from '@mui/x-tree-view';
import ExpandMoreIcon from '@mui/icons-material/ExpandMore';
import ChevronRightIcon from '@mui/icons-material/ChevronRight';

function MyTreeView() {
  return (
    <TreeView
      defaultCollapseIcon={<ExpandMoreIcon />}
      defaultExpandIcon={<ChevronRightIcon />}
    >
      <TreeItem nodeId="1" label="Applications">
        <TreeItem nodeId="2" label="Calendar" />
        <TreeItem nodeId="3" label="Chrome" />
        <TreeItem nodeId="4" label="Webstorm" />
      </TreeItem>
      <TreeItem nodeId="5" label="Documents">
        <TreeItem nodeId="6" label="MUI">
          <TreeItem nodeId="7" label="src">
            <TreeItem nodeId="8" label="index.js" />
            <TreeItem nodeId="9" label="tree-view.js" />
          </TreeItem>
        </TreeItem>
      </TreeItem>
    </TreeView>
  );
}
