How to Redirect and Display Card Details Using React Router and Hooks

In the development of modern web applications, managing navigation and displaying content dynamically is crucial. In this post, we're going to tackle a common scenario in React applications: redirecting to a new page on clicking a card and rendering specific card details. We'll utilize React Router, useParams, and useLocation hooks to achieve this functionality.

The Problem: Navigating with React Router

Suppose you're building a blog-like application where each post is displayed in a card format. When a user clicks on a card, you want to redirect them to a dedicated page that shows detailed information about that specific post. In your code, you might have a structure that looks something like this:

EventList.js: Fetches data from an API and passes it down to Event.js.

Event.js: Renders individual posts as cards.

EventDetails.js: Displays the clicked card's details.

Despite the clear structure, it can be tricky to pass data between components that are not directly connected. Let's explore how to set this up correctly using React Router.

The Solution

Step 1: Updating the Link Component

The first change we need to make is in the Event.js file where we render the cards. We will update the Link component to not just point to a path but also send the card's data to the new route. Here’s how to do it:

This change creates a link that not only specifies the path but also attaches the clicked card's data (post) in the state.

Step 2: Accessing the Data in EventDetails

Next, we need to modify the EventDetails.js component to access the data we just passed via useLocation. Here’s the updated code:

Step 3: Ensure the Router is Set Up Correctly

In your main application file, App.js, make sure your routes are defined correctly to accommodate for the dynamic path:

Conclusion

By enhancing the Link to carry data and utilizing the useLocation hook, you've successfully enabled navigation that carries context with it. Now, when a user clicks a card, they are redirected to a detailed view that reflects the selected post's information.

Final Thoughts

Building responsive and dynamic web applications involves understanding how to manage state and routing effectively. By using React Router and hooks like useParams and useLocation, you can create seamless user experiences that feel intuitive and engaging.
