React Router is a standard library for routing in React. It enables the navigation among views of various components in a React Application, allows changing the browser URL, and keeps the UI in sync with the URL. Let us create a simple application to React to understand how the React Router works.

How does React Router works under the hood?

react-router does does a lot beneath the hood. It uses a history. listen() function to listen for any change in the browser history. When that change happens it triggers a callback, which in this case sets the state to the About component.

What problem does React router solve?

In React, routers help create and navigate between the different URLs that make up your web application. They allow your user to move between the components of your app while preserving user state, and can provide unique URLs for these components to make them more shareable.

How does front end routing work?

Frontend routing is handled from the browser, the framework Angular is a great example. When the browser sends a GET request to the server. In Angular urls are followed by #, and only the url is sent ignoring anything else after a # is detected. The server responses with the defaulted ‘index.

What is Dom react router?

React Router DOM enables you to implement dynamic routing in a web app. Unlike the traditional routing architecture in which the routing is handled in a configuration outside of a running app, React Router DOM facilitates component-based routing according to the needs of the app and platform.

What is routing in backend?

Each request to the backend is eventually executed by a controller. A list of routes is defined which maps a given request to a controller and an action. Routes are defined inside extensions, in file Configuration/Backend/Routes.

Is React CSR or SSR?

js (SSR) vs. Create React App (CSR) Exploring the performance differences between server-side-rendering (SSR) and client-side-rendering (CSR) through simple examples.
