If you’re not completely new to the development game, you know that most modern applications are created with the help of a “stack” of various technological solutions. A “stack” refers to any combination of coding languages, tools, and frameworks developers use to create software products for their clients.
A stack contains different layers of components that play a vital role in the process of software product creation. All stacks are divided between the:
Back-end is focused on the internal hardware that the makes product run, while front-end is focused on the components that allow the user to interact with the software.
There are many “stacks” to choose from, and if you’re not 100% sure what you need - you will probably get lost in all the options. Most developers tend to opt-in for the newest and easiest option on the market. They either go for the freshest stacks or those that have the lightest learning curve.
Unfortunately, that isn’t always the right criteria for choosing the best type of “stack”. Many factors come into play here, like:
As you can see, you need to have a foolproof plan in mind if you don’t want to make the wrong choice because selecting the “stack” can have a negative impact across multiple verticals of the client’s business, like human resource, finance, marketing, and management.
Since this is such an important decision, we at Share IT are going to dedicate this blog post to MERN, a full tech stack that we use for most of our projects.
Every single one of these components plays a crucial role in the web app development process. All of these provide an end-to-end framework for developers to work in. For instance, Mongo DB is a database system, Node JS is a back-end runtime environment, Express JS is a back-end web framework and React is a front-end framework.
So, let’s take a bit closer look at every single one of these components:
In case you’re not familiar with Mongo DB, this is a free open-source, cross-platform document-oriented database program. It is classified as a No SQL database program, which means that data is stored in flexible documents with JSON-based query language. This also means that the size of the content number of fields in the documents tends to vary. The whole data is structured in a way to be prone to change over time.
MongoDB is known as a flexible solution that is always easy to scale. This specific database system is developed by Mongo DB Inc., and is published under a combination of the GNU Affero General Public License and the Apache License.
This is also a free, open-source software. It is released under the MIT licence, and it can be classified as a web application framework for Node.js. To be more precise, Express JS is made for developing web apps and APIs.
Instead of manually writing full web server code in Node.js, developers use this MERN component to simplify the coding process. The best feature of this framework is that devs don’t repeat the same code over and over, as they would with writing Node.js code in the HTTP module.
Many developers often refer to it as the “de facto standard server framework for Node.js”.
This specific library is often used for creating views rendered in HTML. The views that you create in Reach declarative, which means that you don’t have to deploy additional time on managing the changes and effects they have on the data.
With React, the same code can run on both the server and the browser. Because of these, most devs call React the “heart and soul of the MERN stack”.
Node JS was designed with an idea of allowing devs to build scalable network applications.
So, now that you have learned more about what MERN is and what its components are, it’s time to look at this stack from a different angle and discuss its benefits.
There are many online courses about MERN that will have you building your own dynamic web applications in no time. All you really have to do is pick the one that seems best to you and get started right away!
