Update the component with the current route and state synchronization with react router dom

Question

Update the component with the current route and state synchronization with react router dom

Is there a method to synchronize the active route in the browser with the component state?

When I click on "Route 2" in the navigation bar, it gets highlighted as the active route and the browser URL shows "/route2". However, upon refreshing the page, "Route 1" is highlighted even though the browser URL still displays "/route2". Is there a way to keep these two in sync?

To replicate this project, start a new app using vite with react-ts, and then include the following files:

App.tsx

index.css

Finally, delete the contents of App.css.

Don't rely on manually calculating the active route/link when you can use the NavLink component in React Router. The NavLink component automatically handles this functionality for you. You can utilize the children prop of the NavLink to pass a render function prop value that includes an isActive prop which can be used to conditionally apply UI logic within the child components.

<NavLink to="/tasks">
  {({ isActive, isPending, isTransitioning }) => (
    <span className={isActive ? "active" : ""}>Tasks</span>
  )}
</NavLink>

For example:

...
import {
  Routes,
  Route,
  Navigate,
  NavLink,
  Outlet
} from "react-router-dom";
...

const Navbar = () => {
  return (
    <div className="flex justify-between items-center sticky top-0 border-b bg-background px-4 h-12 z-10">
      <h1>App Name</h1>
      <div className="flex gap-4 h-8 items-center">
        <NavLink to="/route1">
          {({ isActive }) => (
            <h2
              className={cn(
                "hover:underline hover:text-blue-500",
                isActive ? "text-blue-500" : null
              )}
            >
              Route 1
            </h2>
          )}
        </NavLink>
        <NavLink to="route2">
          {({ isActive }) => (
            <h2
              className={cn(
                "hover:underline hover:text-blue-500",
                isActive ? "text-blue-500" : null
              )}
            >
              Route 2
            </h2>
          )}
        </NavLink>
      </div>
    </div>
  );
};
