Introduction to React Router

What is React Router?

React Router is a declarative routing library designed specifically for React. It manages navigation and rendering of components based on the URL path.

Unlike traditional server-side routing, React Router handles routing on the client side, enabling faster transitions and a smoother user experience.

• Enables multiple views in a single-page React app.
• Uses URL paths to determine which components to render.
• Prevents full page reloads during navigation.

Core Components of React Router

React Router provides several key components that help define routes and navigation within your app.

• BrowserRouter: Wraps your app and enables HTML5 history API for clean URLs.
• Route: Defines a mapping between a URL path and a component to render.
• Link: Creates navigational links that update the URL without reloading the page.
• Switch (in v5) or Routes (in v6): Renders the first matching route among its children.

How Client-Side Routing Works

Client-side routing means the routing logic runs in the browser, not on the server. When a user clicks a link, React Router intercepts the event, updates the URL, and renders the appropriate component without reloading the page.

This approach leads to faster navigation and a more app-like experience.

• URL changes are handled internally by React Router.
• No full page reloads occur during navigation.
• State and UI remain intact between route changes.
