What is the MEAN Stack?15 June 2020
So what is the MEAN Stack then?
The Four Different Components of the MEAN Stack
MongoDB is particularly lauded for its ability to handle large amounts of data while still allowing for efficient data access. Fields can be added to the database without reloading the entire table, and with just a few clicks, the resources available to your database can be expanded. This is essential in cloud-based environments with unpredictable spikes in user activity and server load.
Express is a web application framework for Node.js, operating as the back-end of the MEAN stack. This means Express manages all interactions between the front-end and the database, providing smooth access and transfer of data to the end user. Since the framework was built with Node functionality in mind, it likewise ensures uniformity in the stack and easier work between the tools.
Express is designed to be both efficient and practical - while it is meant to operate more behind the scenes, Express also offers a variety of helpful tools that can prevent user error and avoid unwanted complications. For example, it uses the CommonJS module standard to prevent inadvertent overwriting of variables within the shared namespace. This can prevent accidental redefining of previous variables, and the subsequent costly errors that ensue.
Node.js is the spine that brings the entire MEAN Stack together. Since Express is literally designed to operate on top of Node.js, and AngularJS integrates seamlessly to Node.js for optimal data processing, Node provides the final piece of the puzzle - an integrated web server, that allows you to easily connect and deploy your MongoDB-powered application to the cloud.
Node.js can support as many as a million simultaneous connections, making it the lynchpin that ensures your processing power and other operations function to their maximum potential. Any owner or host of a cloud application can tell you the stress of usage surges and the potential of major damage to a business or brand from outages, which is why Node is so widely used - it’s been proven by major companies and apps to be up to the task of handling those surges.
So why should I learn the MEAN Stack?
Aside from the benefits of the different MEAN stack technologies, there are some practical reasons for developers new and experienced to become familiar with the MEAN stack for their own professional and personal goals:
Cloud-Based Applications are the Norm
Since cloud-based applications offer startup and business owners significant benefits over traditional hosting, and the growing number of cloud providers have cut costs to very reasonable levels, the demand for cloud app developers has risen in conjunction. Companies are now tailoring their business model specifically to cloud-based platforms, and the shortage of skilled developers has only expanded over the past few years.
But how do I get started?
As with any programming tool or language, the best thing to do is to find a high-quality online coding class to hone your skills. Coding classes like the ones at SoloLearn offer not only comprehensive breakdowns of different languages and tools, but also the chance to unlock achievements, compete against fellow students, and learn at your own pace.
