Navigating Seamlessly in React: Fixing React Router NavLink

When building a React application, smooth navigation between different components is crucial for a good user experience. However, sometimes developers encounter issues where clicking on a NavLink does not reroute them to the intended component, despite the URL appearing to change. This can be frustrating and confusing, especially for newcomers to React.

In this post, we’ll take a look at a common problem where the NavLink does not change the displayed component, and we’ll provide a simple, effective solution.

The Problem

Imagine you have a React application with a navigation bar featuring a NavLink to your projects page. You click the NavLink to navigate, and while the URL changes to localhost:3000/projects, nothing happens on the page; you still see the home component. You have to manually refresh the browser or hit Enter in the address bar to see the new component.

This can happen due to the structure of your application, particularly how and where you define your BrowserRouter component.

Example Code

Here’s a simplified version of what your application might look like:

App.js

The Solution: Proper Usage of BrowserRouter

One of the most common mistakes that lead to this issue is wrapping the NavLink in another BrowserRouter. You should only have one BrowserRouter in your application, which should wrap your navigation and routing components.

Step-by-Step Fix

Remove Nested BrowserRouter:

Eliminate the BrowserRouter wrapping the NavLink in NavBar.js. This is unnecessary and can cause confusion in routing.

Correct Placement:

Ensure that your NavBar component is placed within your main BrowserRouter in App.js, but outside of the Switch. This way, the navigation links are aware of the routing context and will function correctly.

Here’s how your updated components should look:

Conclusion

By properly structuring your routing with a single BrowserRouter, you will solve the problem of the NavLink not changing components. It's a small change that makes a significant impact. Your application will now navigate smoothly from one component to another, providing a better user experience without the need for manual refreshes.

If you encounter similar issues in the future, remember to check your router structure first. Happy coding!
