material-ui Drawer – findDOMNode is deprecated in StrictMode
findDOMNode
is deprecated in StrictMode. This warning is related to the use of findDOMNode
in the Drawer
component of material-ui.
The findDOMNode
method is used to access the underlying DOM node of a React component. However, it is considered an anti-pattern and is discouraged in React’s StrictMode. The reason behind this deprecation is that findDOMNode
can lead to performance issues and can also interfere with the new async rendering capabilities introduced in React 16.
Fortunately, there are alternative solutions to this problem that you can implement in your code. Let’s explore two possible solutions:
Solution 1: Refs
One way to avoid using findDOMNode
is by using the ref
attribute in React. By creating a ref for the Drawer
component, you can directly access its underlying DOM node without relying on findDOMNode
.
{`import React, { useRef } from 'react';
import Drawer from '@material-ui/core/Drawer';
const MyDrawer = () => {
const drawerRef = useRef(null);
const handleButtonClick = () => {
const drawerNode = drawerRef.current;
// Access the drawerNode directly
// Perform necessary operations
};
return (
{/* Drawer content */}
);
};
export default MyDrawer;`}
Solution 2: Use the provided API
Another solution is to utilize the provided API of the Drawer
component. material-ui provides a set of APIs that can be used to control the behavior of the Drawer
component without directly accessing the DOM node.
{`import React, { useState } from 'react';
import Drawer from '@material-ui/core/Drawer';
const MyDrawer = () => {
const [open, setOpen] = useState(false);
const handleButtonClick = () => {
setOpen(true);
// Perform necessary operations
};
const handleClose = () => {
setOpen(false);
// Perform necessary operations
};
return (
<>
{/* Drawer content */}
>
);
};
export default MyDrawer;`}
By utilizing the open
and onClose
props of the Drawer
component, you can control the visibility of the drawer and perform necessary operations when it is opened or closed.
With these alternative solutions, you can avoid using findDOMNode
and ensure that your code is compatible with React’s StrictMode. Make sure to choose the solution that best fits your specific use case.
Remember, it’s important to keep your code up to date and follow best practices to ensure a smooth and efficient development process.
