Tutor:React applications are Single Page Applications (SPAs). This means the browser doesn't load a new HTML page when navigating. Instead, React swaps out components to simulate changing pages. We use React Router to handle this.

Concept: Setup

To enable routing in React, you must wrap your app's component tree in a Router provider.

React Router & Navigation

Author

Pascual Vila

Frontend Instructor // Code Syllabus

React turns your site into a Single Page Application (SPA). Instead of requesting new HTML from the server for every page, React Router intercepts clicks and dynamically swaps out components based on the URL.

The Router Hierarchy

Everything starts with the <BrowserRouter>. It provides routing context to the rest of the application. Inside, we use <Routes> to group our individual <Route> definitions.

Navigating Without Reloading

If you use a standard HTML <a href="/..."> tag, the browser will reload the entire application, destroying your React state. Instead, we use the <Link to="/..."> component to cleanly update the URL and change views.

Dynamic Routes & Parameters

Sometimes you need a route like `/users/1` or `/users/2`. We define this as path="/users/:id". Inside the rendered component, we can access this dynamic ID using the useParams() hook provided by React Router.

This section contains the full detailed transcript covering routing basics in React. We covered the shift from MPA (Multi-Page Applications) to SPA architecture. We looked at how to install `react-router-dom`, configure the `BrowserRouter`, define `Routes`, create navigation `Links`, and extract URL segments using `useParams`.

React Router Glossary

BrowserRouter

The main context provider component that keeps your UI in sync with the browser's URL.

Routes

A container that looks through all its child <Route> elements to find the best match for the current URL.

snippet.jsx

Route

Defines a mapping between a URL path and a React component to render.

snippet.jsx

Link

Used in place of standard <a> tags to allow client-side routing without triggering a full page refresh.

snippet.jsx

Dynamic Segments

URL segments preceded by a colon (:). They allow you to match patterns instead of exact paths.

useParams

A hook that returns an object of key/value pairs of dynamic params from the current URL.
