A Brief Overview of Node.js and Express.js

If you’ve worked with JavaScript frameworks and libraries, chances are that you’ve heard of Node.js and Express.js. So for those who are unfamiliar to these terms – what exactly are they?

Node.js

Node.js is an open-source JavaScript runtime environment, that uses Google’s V8 JavaScript engine, where you can build server applications.┬áNode.js is not a framework, although it has many modules that are written in JavaScript. It has event-driven architecture that is capable of asynchronous I/O, otherwise none as a form of input/output processing that allows other processing to continue before the transfer of data has finished.

Express.js

Express.js is a web application framework for Node.js, that’s used for building APIs. It is also known for being a┬ábackend component of the MEAN stack.

I’ve worked with Node.js and Express.js to create APIs, so I feel like I can never think about one of them without having the other one come to mind.
