Category Archives: React router redirect keep query params

Now we need to explore how to handle route params. Route parameters are parts of the URL that will change based on the object we want to display. That last part of the URL is the parameter. With react-router-domwe designate a dynamic portion of the URL to be matched by putting a colon : before it. Let's explore this by adding a modal that will display a user's information when we click on it.

Notice how this path has a route param called userId. We will see in a little bit that we will have access to this variable in our route. Let's add the route. Add this below our other route. You should see our modal. Notice how you can also see our users table in the background. This is because technically both those routes match. So both are shown. If you try some other numbers for userIdyou will notice that the information being shown never changes.

We need to get access to the dynamic userId being passed into our route and use it to query the correct user from the API. This is easy to do using react-router-dom. The library passes in a prop called match into every route that is rendered. Inside this match object is another object called params.

This holds all matching params where the key is the name we specified when creating the route and the value is the actual value in the URL. Let's update the componentDidMount method in the UserInfo component to use our route param. Here we have pulled the params object out of the match object that is inside this. Try changing the URL to another number and see how it shows the correct information.

Let's update the handleDelete method in the same way. Now that this is working correctly, let's figure out how to remove this modal when we click the "Close" button. This is pretty simple. Try clicking on the "Close" button now. It updates the URL. Now that the URL no longer matches the route that shows the modal, the modal goes away. If you click the "Back" button in the browser, you will see that it moves the URL back to the previous one you had been viewing.

Since this one matches the modal-showing route, it pops back up again. There's one last thing we need to do. We need to make it so that when we click on a user in the table, it pops the modal up by switching to that route.

I think we all know where this is going. We do this by wrapping each user's name in a Link component. Don't forget to import it at the top!

Now try clicking on one of the users' names and notice how the modal pops up. Clicking "Close" will then get rid of it. If you were to click on the "Delete" button, you will notice that nothing seems to happen. If you close the modal and look for the user, however, you will see it has disappeared. The user is being deleted, but the modal isn't being closed.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

This causes a massive amount of re-rendering when used throughout. How can the unwanted params be ignored? I found using render on route along with passing the params myself to be the cleanest solution to not pollute containers with router logic :. Learn more. Asked 1 year, 7 months ago.

However, due to how Redirect is implemented the params aren't added to the existing params, but instead replaced, meaning the :id param is dropped. Is there a way to both pass through the dynamic :id param and add an additional static :type param? If not, would you accept a pull request changing options.

In case anyone else is struggling with this, a hack that seems to work react-router 0. I was sorta expecting this to merge my params and keep the ones already in existence. Granted I could maybe restructure all my urls to avoid this issue, but on a tight deadline and I'm porting my app from react-router-component to this router so have to find the least-change-path for migration and this not providing this functionality is a bummer.

Also, the example provided should be a little clearer in explaining what happens when you use the param. Or is this something that is not welcome? Instead, you just give us the destination URL pattern and we interpolate any existing params into it for convenience. So in your case benjieyou could use:. Skip to content.

How can I define a route in my routes. I tried with the following routes configuration, but the :redirectParam is not catching the mentioned param:. React Router already parses the location for you and passes it to your RouteComponent as props. You can access the query after? If you are looking for the path parameter values, separated with a colon : inside the router, these are accessible via.

This applies to late React Router v3 versions not sure which. Older router versions were reported to use this.

Access Route Params in React Router v4

React Router v4 does not parse the query for you any more, but you can only access it via this. For reasons see nbeuchat's answer. Another library would be query-string. See this answer for some more ideas on parsing the search string. If you do not need IE-compatibility you can also use.

For functional components you would replace this. Note, you could use window. If your non-functional component is not a direct child of a Switch you need to use withRouter to access any of the router provided props.

With React Router v3, you can get query-string from this. With React Router v4, the this. You need to use this. If React Router picked the "right" one, it would only be right for some people. Then, it would need to add a way for other users to substitute in their preferred query parsing package.

There is no internal use of the search string by React Router that requires it to parse the key-value pairs, so it doesn't have a need to pick which one of these should be "right".

The approach being taken for 4. If you need query string parsing or async loading or Redux integration or something else very specific, then you can add that in with a library specifically for your use case.

Less cruft is packed in that you don't need and you can customize things to your specific preferences and needs. You can find the full discussion on GitHub. React Router v4 no longer has the props. So the accepted answer will not work for newer projects. A solution for v4 is to use an outside library query-string to parse the props. When using React hooks there is no access to access to this.Member of Cell Two of the Accelerator Program.

We chose this approach so we could link directly to the page with specific filters selected. Adding the filter values to the query string in the URL offered a reasonable solution. Handling them in React Router is similar to other framework tooling and is simple to learn for query string first-timers. If you are new to React Router or want a refresher on how to retrieve and parse query strings, this guide is for you. Query strings are commonly used for embedding parameters into a URL.

A typical query string might look like this:. The query string follows the? These are typically key-value pairs, but it is possible to embed complex objects or arrays into the URL in the query string. The query string can contain any useful information, such as search strings, filter values, or any transient data that needs to be shared across pages.

React Router gives developers the freedom to do whatever makes sense for their application. The good news is that it is pretty straightforward. To include the search string and filter value in the URL, we want to have a query string that looks something like this:. React Router passes along a few objects in props: historymatchand location.

The one we care about is location because it contains the information about the query params. Now we know we can get the query string via props. So, the next step is parsing.

Rather than simply passing in a raw string key value, you can leverage types for added safety. The types for this route might look like this:. We can pass ProductsRoute. A simple helper function can make it much easier to correctly handle string Boolean values. React Router recommends using a library such as query-stringwhich is available on npm if you are unable to use the built-in browser implementation of the URL API. Run yarn add query-string to add and install it. Parsing query strings is then as simple as passing location.

Query strings add seamless functionality and usability to web applications by passing data between pages via the URL. Your email address will not be published.
