In this scenario Express is used to spin up a server and serve these files. They're typically used to send and receive JSON payloads, usually to and from a database or other service. This was the default way of creating apps in the pre-JavaScript hype era. What're the main types the web supports? There are applications with server rendered HTML pages, which will be familiar to some of you old school programmers. Now you're wondering what kind of apps can you even build with Express? Let's have a second to talk it through. So easy in fact that many other frameworks are based on Express! It makes is easy to create both web apps, and REST APIs with little to no hassle. It only provides a thin layer of fundamental abstraction without changing the core features Node is famous for. Express is today the de-facto primary framework for use with Node.js. One of these modules is Express.js, a super popular, minimalist web framework for quickly building Node.js applications.

Node Package Manager, duh? Here you can find various code modules to use in your applications, or publish your own if you so wish. NPM is the main meeting place for all Node packages, hence its name. The real reason Node.js blew up and became as popular as it is today is the package manager that comes along for the ride. This is why Node is blazingly fast, because it can handle connections concurrently. It handles events without blocking the main thread of execution. JavaScript is single-threaded, so Node's strength lies in its asynchronous nature. It’s designed to build scalable network applications. Node is an asynchronous event driven JavaScript runtime built on Chrome’s V8 JavaScript engine. Today we'll create four different types of apps using Express.js, the most popular Node.js framework.īefore we jump in there are a couple of things we need to go over regarding Node.js and Express, just to get our bearings straight.
If you haven't tried it yet, you'll love it, I'm sure!

But, let's get on the hype train and check out how to build cool stuff with Node.js.
It's like every day a new framework pops up. With the rise of Node.js and npm, JavaScript has become the de-facto most used programming language in the world. Web development has come a long way since the The sheer versatility we have is mind-blowing.
