Also, the route for /books is replaced with a Route component that has no path prop, but instead has an index prop. All this is saying is that the path of the index Route is the same as the parent Route. So that when we click on any particular link, it can be easily identified which Link is active. To do this react router provides a new trick NavLink instead of Link. Now, in the index.js file, replace Link from Navlink and add properties activeStyle. The activeStyle properties mean when we click on the Link, it should have a specific style so that we can differentiate which one is currently active.

And as the router has no cache, it will hit the server again, unless we do something about it. React Router is a massive library with tons of amazing features which is the reason it is the go-to routing library for most people. I really love how they handle things like nesting since it makes creating intuitive and clean routes so much easier.
The loader needs access to the QueryClient.
Finally, we have successfully implemented navigation in our React application using React Router. In other words, data mutations with HTML forms are routing events. The NativeRouter is essentially the equivalent of the BrowserRouter, but for React Native. If you are using React Native then this is the router you will want to use.
Code of conduct
React Router is the most popular routing library in React, but it can be a bit complicated to wrap your head around some of the more complex features. That is why in this article I will be breaking down everything you need to know about React Router so you can use even the most advanced features with ease. GetQueryData does the trick for returning any data we have in the cache, even if it’s stale. This ensures that recurring visits to a page will show data immediately. Only if getQueryData returns undefined , we’ll actually do the fetch.
How do I add a router to React?
Normally in an application you would navigate with anchor tags, but React Router uses its own custom Link component to handle navigation. You’ll also need to provide the matchPath function exported from the react-router-dom or react-router packages. Because of how React Router works, you need to have your components wrapped in a router otherwise all your routing code will throw errors and break.

This bit of code will create two routes, /contact and /about, which both are rendered inside the OtherLayout component. The useNavigation hook on the other hand is a hook I use all the time. This hook is a really simple hook that takes no parameters and returns a single navigate function which you can use to redirect a user to specific pages. The first parameter is the to location you want to redirect the user to and the second parameter is an object that can have keys for replace, and state. The final router is the StaticRouter and this router again has a very specific use case. This router is specifically meant for server rendering your React applications since it takes in a single location prop and renders out your application using that location prop as the URL. The simplest and most common advanced feature in React Router is handling dynamic routes.
We want the loader to wait for our data to be ready and return it to get a good experience on the first loads. We also want errors to be thrown to the errorElement, so fetchQuery is the best option. Note that prefetchQuery doesn’t return anything and catches errors internally . Please use ide.geeksforgeeks.org, generate link and share the link here. The web is a wonderful place where highly dynamic shopping experiences, creative productivity software, and super basic but excellent classified ads are all possible on the same platform.
If you are fine with stale data not being shown in the component, this is a good alternative. The big drawback of not having a cache shows when you go to Contact 2 and then back to Contact 1 again.
- This component works exactly the same as the Link component, but it is specifically for showing active states on links, for example in nav bars.
- Now that covers 95% of what you need to know about React Router, but the library has a bit more depth still.
- There is a lot of cool stuff you can do with routing to make more complex routes, easier to read, and overall much more functional.
- If you find yourself adding Router components to your tests a lot, you may want to create a helper function that wraps around render.
- It is not possible to install react-router directly in your application.
- All this is saying is that the path of the index Route is the same as the parent Route.
- It enables the navigation among views of various components in a React Application, allows changing the browser URL, and keeps the UI in sync with the URL.
If you do decide you want to use the useRoutes hook all the props that you would normally pass to your Route components are instead just passed as key/value pairs of an object. If you want to render two different sections of content that both depend on the URL of the application then you need multiple Routes components. This is very common if for example you have a sidebar you want to render certain content in for certain URLs and also a main page that should show specific content based on the URL. Now the final way you can share layouts with React Router is by wrapping child Route components in a parent Route that only defines an element prop and no path prop. The React router instrumentation uses the React router library to create pageload/navigation transactions and paramaterize transaction names.
Please see Getting Started with React Performance for more details on how to set up and install the SDK. If multiple invalidations are involved, you can also mix and match the two approaches to wait for important refetches, but let less important ones be done in the background. Is it important to avoid potential layout shifts when showing stale data, or do you want to keep the action pending until you have all new data? With this, it is guaranteed that calling useQuery in the component will have some data available, just like calling useLoaderData would. However, TypeScript has no way of knowing this – the data returned is of type Contact | undefined. Setting the staleTime to two minutes tells fetchQuery to resolve data immediately if it’s available and not older than two minutes, otherwise, it will go and fetch it.
