Routing: Routing plays an important role.

• Search engines trace your pages because of Routes.
• Don't change your URL frequently. Routes directly impact your SEO.
• If your website is deployed with some Routes. In future, if you change some Routes, it directly impacts the SEO because Google crawlers are already indexing your website based on the routes.
• A lot of people will try to use the old URL, but this URL has broken, and some users bookmarked the old URL.
• Don't complicate your Routing.
• Keep it as simple as possible.

Protected Routes: Bad :

<Route path="/dashboard" element={ isAuthenticated ? <Dashboard / > : <Login />}>

Note: it displays the Login screen but the URL path is Dashboard and repeats the same process for all pages. Suppose you have 30 pages then you need to write for every page.

Good: Extract the authentication logic into a wrapper.

const ProtectedRoutes({children})=>{
	//write auth logic here...
	let isAuthenticated=false;
	return isAuthenticated? <Outlet /> : <navigate to="/login" />
}

Note: Outlet is the children.

Routes : Single protected Route:

<Route  element={<ProtectedRoute />} >
		<Route path="/about" element={<Dashboard />} />
<Route>
