Express React

React. js: React is a declarative, efficient, and flexible JavaScript library for building user interfaces. ReactJS is an open-source, component-based front-end library responsible only for the view layer of the application. It is maintained by Facebook.

High Server Load: Using Node JS with React can help in handling requests and maintaining server load balance . JSON APIs: You can easily build JSON APIs for your application using Node JS. The reusability of the code enables sharing within React JS.

A common misconception among developers is that Node. js is a backend framework and is only used for building servers. This isn’t true: Node. js can be used both on the frontend and the backend .

Thus, to connect a React frontend with a NodeJS backend, we need to utilize the useEffect hook and the async function fetch() . useEffect will allow us to only run our fetch request once (when the component gets mounted) which will avoid slowing down our app.6 Haz 2021
