We performed the conditional rendering in the useEffect so that the condition will be evaluated in the initial render and before fetching all the data needed in the component. The useNavigate hook is useful for protecting routes and redirecting to a new route within a function as demonstrated in the useEffect function in this section. The explanation above is demonstrated as shown below: Import from "react-router-dom" Ĭonst = useState(false) įrom the above code, we’re checking the login state of the user, if they are not logged in, we want to redirect them to the home component and then redirect them to the login page when they’ve logged in by clicking the “log me in” button. The good news is that React Router v5 is compatible with React > 15, so if youre on v5 (or v4) you should be able to upgrade React without touching any of your router code. Or use the following command to create a new react application: React Router v6 makes heavy use of React hooks, so youll need to be on React 16.8 or greater before attempting the upgrade to React Router v6. The code you've shared in the snippet is from a class component though, so you'll need to create a Higher Order Component to use the useNavigate hook and inject the navigate function as a prop. Skip this section if you have an existing React application playground. React Router v6 ships with a useNavigate hook, which returns us a function that we can call to navigate around our apps with. In react-router-dom6 the way to issue imperative navigation actions is to use the navigate function returned from the useNavigate hook. To achieve navigation in our React application, we’ll make use of the React Router library. You can check out the difference between Next.js and React.js in this blog. React does not include a routing feature out of the box in fact, this is one of the reasons react is not a framework in the first place, but rather a UI library that we can combine with other libraries to achieve our goals.įrontend frameworks like Next.js use a built-in file-based routing system which does not require any setup. React is a single-page application and an un-opinionated JavaScript UI library that does not impose any architecture or principles on you as a developer, instead giving you the flexibility to set up your project as you see fit, including the use of any other library. In this article, we’ll look at using the React Router v6 to implement a redirect in a React application. Thankfully, there's an easy way around it.Redirecting is a vital feature in a frontend application, such as a React app, because it allows us to programmatically redirect from one URL to another without using an anchor link or a React Router component. One of the major blockers when it comes to switching to React Router v6 is that the new version fully embraces React hooks - meaning that the withRouter HOC (higher-order component) is no longer part of the library.Īs a consequence, if withRouter is used extensively in our application, especially with class components that cannot be immediately switched to React hooks, we are in for a major refactor. But, as with every major upgrade, inevitably there are breaking changes. Among other improvements, React Router v6 has been built from the ground up using React hooks, making it more compatible with future versions of React and reducing its bundle size significantly. React developers who are still using older versions of the library are probably aching to upgrade. React Router v6 has been around for a while now.
