Understanding the Challenge: React Router 6 and TypeScript

When working with React Router 6 in TypeScript, developers may encounter issues that can be confusing, particularly with how to display nested routes. One common problem arises when a developer expects child components to render inside a parent component (like AppFrame) but finds that it isn’t happening as anticipated. Instead, they only see the parent component rendered, without any children inside it. If you've faced this issue, you're not alone! In this guide, we'll explore why this happens and the correct approach to implement nested routes with React Router 6 and TypeScript.

The Problem Explained

In JavaScript, it’s typical to structure React Router as follows:

Here, the ProductView component should render within the AppFrame, where we ideally have the {children} prop.

However, when transitioning this code to TypeScript, many developers find that while the AppFrame appears, the ProductView does not, leading to frustration and confusion.

The Solution: Using Outlet in React Router 6

The solution lies in using the Outlet component that React Router 6 provides for rendering child routes. Instead of directly using {children} to represent child components, you will need to replace it with <Outlet />. This allows React Router to understand where to display the children components correctly.

Step-by-Step Implementation

Import the Outlet Component:
Begin by importing Outlet from react-router-dom in your AppFrame component. This component acts as a placeholder for rendering the matched child route.

Modify the AppFrame Component:
Update the AppFrame to include the Outlet component as follows:

Keep the ProductView Component as It Is:
Your ProductView component can remain unchanged:

Maintain Your Routing Structure:
Lastly, ensure that your routing structure stays the same as shown earlier. There’s no need to change your routes; just ensure you use the Outlet in your layout component.

Summary

By utilizing the Outlet component, you can effectively manage nested routing in React Router 6 while using TypeScript. This allows React Router to render child components correctly within their parent routes.

Conclusion

In this post, we delved into a common issue faced by many developers using React Router 6 and TypeScript, specifically regarding component rendering. Instead of relying on passing components through props, make sure to leverage the Outlet component in your parent component. This method ensures your UI displays the intended nested components seamlessly, enhancing both your development workflow and the user experience.

By following this guide, you should now have a clearer understanding of how to handle nested routes in your React applications effectively! Happy coding!
