Simplify Responsive Design in React with useBreakpoints
Jan 21, 2025 pm 04:06 PMWhen building modern web applications, responsive design that runs smoothly on all screen sizes is not a nice-to-have, but an essential feature. A good way to achieve this is to handle mobile and desktop views separately. This is where useBreakpoints
hooks come into play! It is a handy tool that helps developers create user-friendly experiences on various devices.
What is a useBreakpoints
hook?
The useBreakpoints
hook is a custom React hook that leverages Material-UI's useTheme
and useMediaQuery
hooks. It determines the current screen size so you can decide what to display or how to style it based on whether the user is on a phone or a computer.
Why use useBreakpoints
?
- Improving user experience: By customizing the interface for mobile and desktop users, you can ensure everyone gets the best experience. Mobile users see a simple and smooth design, while desktop users can enjoy a more detailed layout.
-
Simpler code: CSS files are no longer littered with media queries.

Hooks allow you to handle reactive logic directly in your components, making your code easier to read and maintain. - Faster performance: By displaying only the content required for a specific screen size, you can reduce unnecessary data loading and speed up your application.
-
Project Consistency: Using
useBreakpoints
hooks in your project can maintain consistency and help new team members get started quickly.
How to use useBreakpoints
hook
Here is a quick guide on how to set up and use useBreakpoints
hooks in your React application.
Step 1: Set up the hook
First, create a custom hook using Material-UI's useTheme
and useMediaQuery
to determine the screen size.
import { useMediaQuery, useTheme } from '@mui/material'; /** * 自定义钩子,根据主题获取断点的当前状态。 */ export const useBreakpoints = () => { const theme = useTheme(); const isMd = useMediaQuery(theme.breakpoints.only('md')); return { isMd, }; };
Step 2: Use Hooks
Now use the useBreakpoints
hook in a component to display different layouts for mobile and desktop users. For example, you can use the Material-UI component to display a list for mobile users and a table for desktop users.
import React from 'react'; import { useBreakpoints } from '/Users/jack/Work/SGInnovate/frontend/packages/shared/ui/utils/breakpoints'; import { Table, TableBody, TableCell, TableContainer, TableHead, TableRow, List, ListItem, Paper } from '@mui/material'; const ResponsiveComponent = () => { const { isMdDown } = useBreakpoints(); const data = [ { id: 1, name: 'Item 1', value: 'Value 1' }, { id: 2, name: 'Item 2', value: 'Value 2' }, { id: 3, name: 'Item 3', value: 'Value 3' }, ]; return ( <div> {isMdDown ? ( <List> {data.map((item) => ( <ListItem key={item.id}>{item.name}: {item.value}</ListItem> ))} </List> ) : ( <TableContainer component={Paper}> <Table> <TableHead> <TableRow> <TableCell>Name</TableCell> <TableCell>Value</TableCell> </TableRow> </TableHead> <TableBody> {data.map((item) => ( <TableRow key={item.id}> <TableCell>{item.name}</TableCell> <TableCell>{item.value}</TableCell> </TableRow> ))} </TableBody> </Table> </TableContainer> )} </div> ); }; export default ResponsiveComponent;
That’s it! Using useBreakpoints
hooks, you can easily make your application responsive and user-friendly.
