What methods can be used to identify the specific Router component being rendered in React?

I am currently working with a Navbar component that I want to render with different CSS styles using styled-components based on the route of the component being rendered. How can I determine whether that component is being rendered or not?

const NavbarContainer = styled.div`
  height: 115px;
  font-family: 'Domine', serif;
  align-content: center;
  align-items: center;
  position: absolute;
  z-index: 4;
  width: 100vw;
  overflow: hidden;

  &:hover {
    background-color: white;
    color: black !important;
  }
`;

For example, let's say I want to change the CSS property from position: absolute to position: static in the Login page but keep it as position: absolute in the home page. How can I accomplish this dynamic styling?

Answer №1

Develop a customized version of the NavbarContainer specifically designed for the login route, where you will override the existing position rule. Utilize layout routes to properly display the appropriate routes with their corresponding layouts and navigational bars.

For instance:

const NavbarCustom = styled.div`
  height: 115px;
  font-family: 'Domine', serif;
  align-content: center;
  align-items: center;
  position: absolute;
  z-index: 4;
  width: 100vw;
  overflow: hidden;

  &:hover {
    background-color: white;
    color: black !important;
  }
`;

const StaticNavbarCustom = styled(NavbarCustom)`
  position: static;
`;

...

import { Outlet } from 'react-router-dom';

const NavbarLayout = ({ children }) => (
  <>
    <NavbarCustom>{children}</NavbarCustom>
    <Outlet />
  </>
);

const StaticNavbarLayout = ({ children }) => (
  <>
    <StaticNavbarCustom>{children}</StaticNavbarCustom>
    <Outlet />
  </>
);

...

<Routes>
  <Route
    element={(
      <NavbarLayout>
        // ... include links as child components
      </NavbarLayout>
    )}
  >
    <Route path="/" element={<Home />} />
    // ... define routes with navbar in absolute position
  </Route>

  <Route
    element={(
      <StaticNavbarLayout>
        // ... include links as child components
      </StaticNavbarLayout>
    )}
  >
    <Route path="/login" element={<Login />} />
    // ... other routes with navbar in static position
  </Route>

  // ... additional routes without navigation bars
</Routes>
