JavaScript was the bane of the web development industry during the early days of the browser-rendered Internet. It now powers hugely impactful libraries such as jQuery, and JavaScript-rendered (as opposed to server-side-rendered) content is even indexed by many search engines. What was once largely considered an annoying language used primarily to generate pop-up windows and alert boxes, has now become arguably the most popular programming language in the world.
Not only is JavaScript now more prevalent than ever in frontend architecture, but it has become a server-side language as well, thanks to the Node.js runtime. We have also seen the proliferation of document-oriented databases, such as MongoDB, which store and return JSON data. With JavaScript present throughout the development stack, the door is now open for JavaScript developers to become full-stack developers without the need to learn a traditional server-side language. Given the right tools and know-how, any JavaScript developer can create single page applications comprised entirely of the language they know best, and they can do so using an architecture like MEAN (MongoDB, Express, AngularJS, and Node.js).
Organization is key to the development of any complex Single Page Application (SPA). If you don't get organized from the beginning, you are sure to introduce an inordinate number of regressions to your app. The Node.js ecosystem will help you to do this with a full suite of indispensable and open-source tools, three of which we will discuss here.
In this chapter, you will learn about:
Node Package Manager (NPM)
Bower frontend package manager
Grunt JavaScript task runner
How these three tools can be used together to create an organized development environment that is ideal for creating an SPA and is essential to the MEAN stack architecture.
