Build a CRUD App in React with Tanstack Query and Material UI

In order to follow along with this tutorial, you'll need a basic knowledge of HTML, CSS, and JavaScript/ES6. You should also know the fundamentals of React, which you can learn by reading Quick Start with React.

In this tutorial we will make a simple CRUD app. We will fetch users from the remote API and you will be able to add, update or delete them.

While implementing this app we will use:

• React Material UI
• TanStack Query
• custom hooks
• React Context API

Here is a diagram of what we will implement.

As you can see, here are two sections each with its own responsibility. One for create and edit user data and another for visualize the list of users.

First, let's a component responsible for all users data on the page.

components/users.js

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

export const Users = () => {
  return (
    <Container 
      maxWidth="md" 
      sx={{ margin: '20px auto' }}>
    </Container>
  );
}

The Container component is used to center your content horizontally.

• maxWidth="md": This sets the maximum width of the container. The md value means that the maximum width is set to the value defined for medium-sized screens in Material-UI's theme. This is a way to make the component responsive.
• sx={{ margin: '20px auto' }}: This is a shorthand for inline styles. sx is a special property provided by Material-UI for customizing styles.

Then, let's implement a component to render list of users.

components/users-table.js

import { 
  Paper, 
  Table, 
  TableBody, 
  TableCell, 
  TableContainer, 
  TableHead, 
  TableRow 
} from "@mui/material"

export const UsersTable = () => {
  return (
    <TableContainer component={Paper}>
      <Table>
        <TableHead>
          <TableRow>
            <TableCell>Name</TableCell>
            <TableCell>Email</TableCell>
          </TableRow>
        </TableHead>
        <TableBody></TableBody>
      </Table>
    </TableContainer>
  );
}

Let's explain the code above.

• <TableContainer component={Paper}>: The TableContainer component is used as a container for the Table. It uses the Paper component as its base, which gives it a Material design look with a shadow and background.
• Table, TableHead, TableBody, TableRow and TableCell are just wrappers for native elements of the table.

Now, import UsersTable inside Users.

components/users.js

import { Container } from '@mui/material';
import { UsersTable } from './users-table';

export const Users = () => {
  return (
    <Container 
      maxWidth="md" 
      sx={{ margin: '20px auto' }}>
      <UsersTable />
    </Container>
  );
}

And Users inside App.

App.js

import { Users } from './components/users';

export default function App() {
  return <Users />;
}

At this moment you should see three table head sections without any data inside the table. It is an expected behaviour.
