What are different types of Router components in React Router?

React Router offers several Router components, each suited to different environments:

  1. BrowserRouter

    • Uses HTML5 history API (pushState, popState) for clean URLs like /home, /about.
    • Best for web apps served from a server that can handle dynamic URLs.

  2. HashRouter

    • Uses the hash portion of the URL (#) for routing like /#/home.
    • Good for static sites or apps hosted on servers that can't handle server-side routing.

  3. MemoryRouter

    • Stores the history of the URL in memory, not in the browser address bar.
    • Useful for testing or non-browser environments like React Native.

  4. NativeRouter

    • Specifically for React Native applications.
    • Handles routing inside mobile apps without a traditional web browser.

  5. StaticRouter

    • Used mainly for server-side rendering (SSR) in frameworks like Next.js.
    • Accepts a location prop and renders the correct component without changing the browser URL.

Tip: Choose the Router type based on your environment — web, mobile, static site, or server-side rendered app!
