A Closer Look at the MEAN Stack

The LAMP stack – which stands for Linux, Apache, MySQL, and PHP – has been standard practice for web development at many shops for nearly a decade. Since the one constant in the technology world is its rapid pace of change, it stands to reason a new standard is emerging in this software development space. The MEAN stack leverages many recent innovations in technology, including NoSQL databases in addition to some popular JavaScript libraries.

What follows is a high level overview of the MEAN stack to give you some food for thought before architecting your next web development project. Leverage these insights to make an informed decision on which development stack works best for your needs.

What is “MEAN?”

The MEAN stack is made up of MongoDB, one of the most preeminent NoSQL databases, used in combination with three popular JavaScript frameworks, ExpressJS, AngularJS, and Node.js. The fact that nearly all code for a MEAN project – from database to client – is written in JavaScript is one of the main reasons for its rapid growth. If your organization boasts a lot of JavaScript coding talent, it makes MEAN worthy of consideration on your next web project.

The Four Components of the MEAN Stack

MongoDB is a NoSQL document database widely popular for all kinds of applications. MongoDB is also available through many Cloud service providers, including Amazon AMS, Microsoft Azure, and Google Cloud. It leverages the JSON format for data transfer, making it highly appropriate as the database of choice for MEAN.

A lightweight framework for architecting web applications, ExpressJS was inspired by the popular Ruby library, Sinatra. It is a high performance framework well suited for both scalability and concurrency. It also facilitates the creation of unique APIs specifically for use in a web application.

AngularJS is a Google-developed framework for quickly building web-based user interfaces. It makes the creation of dynamic web pages a breeze; leveraging two-way data binding along with other useful features, including client-side code execution and support for the MVC model. Angular’s extensibility and flexibility enhances its compatibility with other frameworks and libraries, in addition to being a major component of the MEAN stack.

Node.js provides the server side execution environment for a MEAN application. Expect a high scalability factor even with a server farm charged with hosting multiple applications. Built upon version 8 of the Chrome JavaScript runtime engine, Node.js by itself is growing in usage among development teams.

The Advantages of the MEAN Stack

Obviously, the fact that all server and client code is written in JavaScript remains of the major advantages of the MEAN stack. Companies are able to take advantage of their staff’s familiarity with a scripting language that’s been around for two decades. Any overall learning curve is lessened by simply focusing on learning MEAN’s three libraries and MongoDB. 

The scalability features of ExpressJS and Node.js make the MEAN stack suitable for the highly concurrent web applications currently in vogue throughout the technology world. The flexibility of the libraries used in MEAN make it easy to swap out any of the components for a library (or database) more familiar to your development staff. It is definitely worthy of exploration for use in your team’s next web development project.

GitHub Analysis reveals the Changing Face of Programming Language Usage

One obvious constant in the technology industry is its rapid pace of change, and the practice of programming offers no exception to this rule. What was once a popular language at the turn of the century might hardly get used for applications today. On the other hard, new programming languages seem to appear on a monthly basis.

Data from the source code repository, GitHub, offers a window on this changing face of software development. Let’s look more closely at their analysis to check the latest trends in programming language usage. Perhaps these insights might be of use in your own team’s development efforts?

393 Different Programming Languages at GitHub – in One Year!

GitHub boasts 4.5 million users who maintain around 10 TB of source code at the repository. Incredibly, those development projects are written in 393 different programming languages. Even more impressive is that data only represents one year of GitHub usage statistics!

Those numbers have only increased since the original July publication of an article by Waren Long at the source{d} blog used as a reference for this post. Another interesting point is their analysis doesn’t even include JavaScript, one of the most widely used languages, because of GitHub users’ propensity to refer to popular libraries, like Node.js or React.js, as a project’s language instead of JavaScript.

Long’s methodology for determining programming language is quite detailed, so refer to the link in the previous paragraph for additional insights, if interested. 

The Current Most Popular Programming Languages on GitHub

There are few surprises listed among the most popular languages currently in use at GitHub. Python and Java rank at the top of the list, with a popularity percentage of 16 and 15.3 respectively. That doesn’t necessarily mean both languages have more lines of source code stored in the repository. That honor lies with PHP, even though it only ranks at #5 on the popularity scale.

Other languages in the top 10 include the venerable, like C, C++, and C#, along with relative upstarts like Ruby, Objective-C, and Go. Apple’s newer programming language for iOS applications, Swift, rounds out the top 10. A related analysis adding in Google search queries to the GitHub data notes that Go is currently the “hottest” programming language.

Moving from One Language to Another

The original source{d} blog article also looked what languages programmers are transitioning into over time. This is useful information for both individual developers as well as software development shops. For example, many Visual Basic developers eventually transition into C#, which isn’t surprising for programmers working primarily on the Microsoft technology stack.

PHP developers, on the other hand, tend to move into Java, Python, or even C#. Python’s current popularity is confirmed by the fact that 24 percent of programmers working in the five other most popular languages — Java, C, C++, PHP, and Ruby – eventually work with Python. The “walled garden” nature of Apple platforms is revealed by the high percentage of programmers switching between Swift and Objective-C for project work.

Ultimately, anyone working as a programmer or a manager of software development needs to dive into the source{d} analysis of GitHub’s data. It’s truly fascinating.
