How to Implement a Nested Route with a Dynamic Route in React Router

Navigating a web app can often involve dealing with multiple layers of pages, especially when building a modern application using React. One common challenge developers face is how to implement a nested route alongside a dynamic route with React Router. In this post, we will address this problem, providing a clear solution to help you add nested routes to your application effectively.

Understanding the Problem

Imagine you are building a character information web application. You have cards displaying character details, which, when clicked, lead to a detailed view. The URL structure would appear as follows:

localhost/info/:id for character details (where :id is a dynamic parameter).

However, within this details page, you also want to provide a link that navigates to localhost/info/:id/episodes to show character episodes. The main challenge here is how to correctly render these nested routes while ensuring the appropriate components display together.

Solution Overview

The key to implementing nested routes with dynamic parameters is to use the Outlet component from React Router. This component allows you to designate where nested route components will be rendered inside their parent route component. Below we will break down the steps required to properly set this up in your application.

1. Setting Up the Routes

You need to organize your routing configuration correctly. Here’s how you can structure your AllRoutes component:

Explanation:

The nested route for the Episodes component is added as a child of the CharacterInfo route. This means it is associated with the specific character ID.

2. Updating the CharacterInfo Component

Next, you'll want to update the CharacterInfo component to utilize the Outlet for rendering nested components. Here’s what your updated component would look like:

3. Concluding the Setup

With the Outlet component included in CharacterInfo, when the Episodes link is clicked, the Episodes component will render in place of the Outlet. This ensures that your application can handle nested routing while maintaining the context of the displayed character information.

Example of the Episodes Component

Here's a simple implementation of the Episodes component, just for clarity:

Final Thoughts

By following this guide, you will have equipped your React application with the ability to handle nested routes effectively using dynamic parameters. Implementing nested routing opens up a wealth of navigational capabilities for your app, allowing for more complex and organized pathways.

This structure not only makes your application user-friendly but also improves code organization and maintainability. Keep experimenting with routes and pushing the limits of what you can build with React Router!
