How to Programmatically Redirect in React Router v6 from a Class Component?

In React Router v6, how do I programmatically redirect to a specific route from a class component?
Problem:
When attempting to programmatically redirect to a different route from a class component in React Router v6, you may encounter the following error:
TypeError: Cannot read properties of undefined (reading 'push')
This error occurs because the navigate prop is not available on class components in v6. Instead, it is only accessible to function components.
Solution:
There are two ways to resolve this issue:
-
Convert the class component to a function component:
- Convert the AddContacts class component to a functional component using hooks (e.g., useState, useEffect, and useNavigate).
-
Create a custom withRouter HOC:
- Create a Higher Order Component (HOC) called withRouter that injects the navigate prop and other React Router hooks into the wrapped component.
- Decorate the AddContacts component with the withRouter HOC in the following way:
import withRouter from './withRouter'; // Change this to the path of your custom HOC file export default withRouter(AddContacts);
This will provide the navigate prop to the AddContacts component.
Additional Note:
In React Router v6, the navigation function is no longer an object but a function that takes in the target path as the first argument and an optional options object as the second argument.
interface NavigateFunction {
(
to: To,
options?: { replace?: boolean; state?: State }
): void;
(delta: number): void;
}
This means that the syntax for navigation has also changed. To navigate to a route using navigate, invoke the function as follows:
// Example usage
this.props.navigate("/");
By following either of the above solutions, you should be able to programmatically redirect to different routes in React Router v6.

How to work with dates and times in js?
Jul 01, 2025 am 01:27 AM
The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.

How can you reduce the payload size of a JavaScript application?
Jun 26, 2025 am 12:54 AM
If JavaScript applications load slowly and have poor performance, the problem is that the payload is too large. Solutions include: 1. Use code splitting (CodeSplitting), split the large bundle into multiple small files through React.lazy() or build tools, and load it as needed to reduce the first download; 2. Remove unused code (TreeShaking), use the ES6 module mechanism to clear "dead code" to ensure that the introduced libraries support this feature; 3. Compress and merge resource files, enable Gzip/Brotli and Terser to compress JS, reasonably merge files and optimize static resources; 4. Replace heavy-duty dependencies and choose lightweight libraries such as day.js and fetch
