How do React & NodeJS work together?

Node and React can be used together.

There is even the MERN stack that helps with that:

MERN is a scaffolding tool which makes it easy to build universal apps using Mongo, Express, React and NodeJS. It minimises the setup time and gets you up to speed using proven technologies.

See: http://mernjs.org/

But you can use React with any other Node framework, not only with Express. React can work with any REST API so whatever you use to build a REST API can be consumed by the frontend written in React.

Some other options include: Hapi, Restify, LoopBack. For more see:

from the official React Documentation React is "a JavaScript library for build user interfaces". In very watered down terms (and I mean watered down) React could be thought of as a templating library (please don't shoot me for that).

What I've learned about React is it is more like the "V"iew in MVC. It provides you a way to present the user interface using JavaScript and JSX. With the little I know about from various tutorials, I really like working with React.
