Introducing Router Version 6: Breaking Changes and Updates

Updating React Apps with React Router 6

Router version 6 has recently been released, bringing along several breaking changes. This means that if you have any React apps that use React Router, you’ll need to go ahead and update them. However, this update may prove to be a bit of a hassle if you have YouTube videos or courses that are based on version 5, as they would become outdated. But not to worry, I have some good news for you. I will be releasing my React Front to Back 2022 course this week, which includes three new projects that are fully updated to use React Router 6. In addition, I will even add a fourth project to make sure everything is up to date with React Router 6. In this article, I will guide you on how to update your React apps using React Router 6, and also provide you with some additional changes to be aware of.

Updating React Crash Course for Router 6

As mentioned earlier, I will now update my previous React crash course to be compatible with React Router 6. Although some of the changes may not directly relate to the specific project in the course, it will still be beneficial for you to learn about these changes. To get started, I will clone the existing project to my machine and navigate to the ‘React-Crash’ directory. From there, I will update the version of React Router which is currently at 5.2. In the terminal, I will run the command ‘npm install react-router-dom@latest’, which should install version 6.2 of React Router.

Opening the Project with VS Code

Once the installation is complete, I will open the project in VS Code by navigating to the project directory. Opening the ‘package.json’ file, you can see that the latest version of React Router is now 6.2. This means that we are ready to start updating our React app with the new changes.

Running the Project and Identifying Errors

To run the project, we need to start the back end server using JSON Server. In the terminal, I will run ‘npm run server’ to start the JSON Server. Next, in another terminal, I will run ‘npm start’ to start the front end and open the project in the browser. However, you may encounter an error message stating that a route should only be used as the child of the routes element. This indicates the first major change in Router version 6.

Understanding the Switch Element Change

One of the significant changes in React Router 6 is the removal of the ‘Switch’ component. The ‘Switch’ component was used in previous versions to render only the first route that matches the current location. However, in version 6, the ‘Switch’ component has been replaced with a new approach. Instead, we now use the ‘Route’ component inside a ‘Routes’ component to define our routes.

The New Way to Handle Routes in App.js

Routing in JavaScript applications has traditionally been handled using the switch statement. However, there have been some recent changes that have switched the approach to using routes. In this article, we will explore this change and how it affects the way we handle routes in the app.js file.

Previously, the Switch Statement

In the past, wrapping routes in a switch statement was not necessary. However, with the new changes, it is now required. Let’s take a look at an example in the app.js file:


<Route exact path=”/about” component={About} />

<Route path=”/other” render={() => } />


As you can see, we now need to wrap our routes in a <Switch> element. This ensures that only one route is rendered at a time.

Introducing the New Routes Element

To make use of the new routing mechanism, we need to add the <Routes> element in our app.js file. Let’s take a look at how to do this:


<Route path=”/about” element={} />

<Route path=”/other” element={} />


Notice the changes we made. Instead of using the component prop, we now use the element prop to specify the component to render. Additionally, we no longer need to specify the exact prop as the new routing system automatically handles exact matching.

Understanding the Changes in React Router v6

React Router is a popular library in the React ecosystem that enables developers to handle routing in their applications efficiently. With the release of React Router version 6, several significant changes have been introduced. In this article, we will explore these changes and understand how they affect our development process.

The Switch to Routes and Elements

One of the notable changes in React Router v6 is the switch from using the “Switch” component to the “Routes” component. Instead of specifying different routes inside a Switch component, we now use the Routes component. This change allows for more flexibility and better organization of routes.

Furthermore, v6 introduces a new concept called “element” instead of the familiar “component” prop. Instead of using the “component” prop to specify the JSX component to render for a particular route, we now use the “element” prop. This change enables us to render any JSX code or element, providing more freedom in designing our routes.

Limitations of Component Children

While the introduction of the “element” prop brings flexibility, it also enforces certain limitations. In React Router v6, all children of the Routes component must either be a Route or a React fragment. If we try to include any other components such as h3 or div elements directly as children, we will encounter an error.

This limitation ensures that the routing structure remains consistent and prevents any potential conflicts or rendering issues. Therefore, it is essential to ensure that all component children of the Routes element are either Routes or React fragments.

Creating Custom Routes with Parameters

In React Router v6, creating custom routes with parameters is straightforward. We can easily define routes that accept dynamic values by specifying a parameter in the route’s path. For example, if we want to create a route for displaying task details, we can define it as “/task/:id”. Here, the “:id” serves as a placeholder for the actual task ID.

To utilize this custom route, we need to import the corresponding component and include it in the Routes component. This allows us to map the dynamic URL parameters to the correct component and ensure that the desired task details are displayed.

By leveraging these custom routes with parameters, we can build more interactive and dynamic applications that cater to individual task details.

Understanding Params in React Router

React Router is a powerful tool that allows developers to handle routing in their React applications. One essential feature of React Router is the ability to pass parameters, or “params”, to routes. In this article, we will explore how to deal with params in React Router, specifically in version 6.

Passing Params in Links

To pass params in React Router version 6, we follow a simple syntax. We use a colon followed by the name we want to assign to the param. For example, if we have a param called “id”, we can create a link that hits a specific route as follows:



In the above code snippet, we are creating a link that navigates to the “task” route with the specific task ID.

Accessing Params in Components

Once we have passed the params through the link, we need to access them in the component. React Router version 6 provides two ways to access params: using the `params` variable or destructuring the params object.

Using the `params` variable:


Const params = useParams();


In the code snippet above, we are using the `useParams` hook to retrieve the params object. We can then access specific params using `params.paramName`.

Destructuring params:


Const { id } = useParams();


In the code snippet above, we are destructuring the `params` object to directly access the `id` param.

Utilizing Params in API Requests

Once we have access to the params in our component, we can utilize them in API requests. In the example below, we are making a request to fetch a specific task from the backend or JSON server using the task ID passed as a param:




By utilizing the `` value in our API request, we can retrieve the relevant data for that specific task.

Changes in React Router Version 6

React Router is a popular library used in React applications to handle routing. With the release of version 6, there have been some changes that developers need to be aware of. In this article, we will discuss a few of these changes and how they affect your code.

No More Props in Match

In previous versions of React Router, you could access the URL parameters using the match object. However, in version 6, this has changed. The props in match are no longer available, so you need to use a different approach.

Instead of accessing the URL parameters through props, you can now use the useParams hook. This hook allows you to access the parameters directly from the URL. Here is an example:

Import { useParams } from ‘react-router-dom’;

Function MyComponent() {

Const { id } = useParams();

Return (


<h1>Post ID: {id}</h1>




In the above example, we are using the useParams hook to get the id parameter from the URL.

Changes in Redirect Component

In previous versions of React Router, you could use the Redirect component to navigate to a different page programmatically. However, in version 6, the Redirect component has been replaced with navigate.

Here is an example of how you could use the navigate function:

Import { useState } from ‘react’;

Import { navigate } from ‘react-router-dom’;

Function MyComponent() {

Const [error, setError] = useState(”);

Const handleRedirect = () => {

If (error) {

SetError(‘Task not found’);




Return (


<button onClick={handleRedirect}>Redirect</button>




In the above example, we use the navigate function to redirect to the ‘/error’ page if there is an error. This replaces the previous usage of Redirect component.

How to Efficiently Navigate to Different Pages in React

React is a popular JavaScript library used for building user interfaces. One common task in React applications involves navigating to different pages or components based on certain events or user actions. In this article, we will explore how to efficiently navigate to different pages using React’s built-in hooks and utilities.

The Use Navigate Hook

One useful hook provided by React is the “useNavigate” hook. This hook allows us to navigate to different pages without the need for additional setup or external libraries. To use this hook, we first need to import it from the react-router-dom package:


Import { useNavigate } from ‘react-router-dom’;


Once imported, we can initialize the `navigate` constant using the `useNavigate` hook:


Const navigate = useNavigate();


Now, instead of manually setting an error or returning the navigate function, we can simply call the `navigate` function wherever we want to go. For example, if we want to redirect the user to the home page, we can simply write:




This will navigate the user to the root path, which is the equivalent of the home page.

Implementing a “Go Back” Button

In some cases, we may want to provide a “Go Back” button on a details page or component. To do this, we can create a custom button component and use the `navigate` function to go back to the previous page. Let’s assume we have a custom button component imported as `Button`:


Import Button from ‘./Button’;


To add a “Go Back” button, we can simply use the `Button` component and specify the text prop as “Go Back”:



We can also add an onClick event handler to the button and call the `navigate` function with the parameter `-1`:


Navigate(-1)} />


This will navigate the user back to the previous page in the browser’s history.

Exploring the Changes in React Router Version 6

React Router is a powerful tool used in building single-page applications with dynamic routing capabilities. With the recent release of version 6, there have been several changes and updates that developers need to be aware of. Let’s dive into some of the key changes and understand how they affect our projects.

Switch to Routes

One of the notable changes in React Router version 6 is the replacement of the “Switch” component with “Routes”. Previously, we used “Switch” to render the first matching route exclusively. However, now we have to use “Routes” instead. This means every route declaration must be wrapped within the “Routes” element.

Component is now Element

In version 6, the “component” prop has been changed to “element”. This change gives developers more flexibility in defining and rendering their JSX code. The “element” prop allows any JSX element to be rendered, making it an exciting enhancement in terms of customization and code organization.

Redirect is now Navigate

The “Redirect” component in previous versions has been replaced with “Navigate” in React Router version 6. The functionality remains the same – redirecting users to a specific route. However, now we need to use “Navigate” instead of “Redirect” to achieve this behavior. This change simplifies the redirection process and aligns it more closely with overall routing logic.

Improved Back Navigation

Back navigation has always been a crucial aspect of user experience. With version 6, React Router introduces a more efficient and flexible way to handle back navigation. By using the “useLocation” hook, developers can access location data, including the pathname. This allows for easy tracking and manipulation of the path when needed. For example, displaying the current path in a component becomes as simple as adding the path name from the “useLocation” hook.

The Impact of Changes in a Technology Stack

In the constantly evolving world of technology, changes are inevitable. Whether it’s in programming languages, frameworks, or libraries, updates and modifications are made to improve functionality, fix bugs, and enhance user experience. However, these changes can sometimes cause inconvenience and frustration for both developers and content creators.
