React Router

What is React Router?

The standard routing library for React applications, enabling declarative routing and navigation in single-page applications. Provides a collection of navigational components that compose declaratively with your application. Supports nested routes, route parameters, query strings, and programmatic navigation. Features code splitting, lazy loading, and seamless integration with React's component model. Powers routing for millions of React applications worldwide.

When to use it

• Essential for any React application that requires multiple pages or views.
• Perfect for building SPAs with navigation, deep linking, and browser history support.
• Commonly used in web applications, admin dashboards, e-commerce sites, and content management systems.
• Enables SEO-friendly routing with server-side rendering support.

When NOT to use it

• Single-page applications with no navigation - unnecessary overhead
• When using Next.js or Remix - they have built-in routing
• Simple apps with one or two views - conditional rendering is simpler
• Static sites - use file-based routing with Next.js or Astro instead
