A Closer Look at the MERN vs. MEAN Stack
Just like any other profession that usually has a predefined set of tools that make their jobs way easier and better, software developers do have the same predefined sets. Stacks are any software developer’s go-to when they would like to save time and effort and make their software development journey easier and more streamlined. Developers use these stacks for web, software, and app development. Among the many stacks that you can use for developing apps and websites, there are two that stood out and gained much recognition and popularity: the MERN and MEAN stacks. In this article, we will establish a great comparison of MERN vs MEAN stacks. Read this article to learn all about them: their definitions, advantages, and key differences.
What is MERN Stack?
As the name implies, a stack is a pile of things organized on top of each other. Sometimes it is clothes, books, pictures, etc. However, in this case, the stack is a pile of tools and resources organized to help software developers have an easy yet effective development experience. Each of these resources is usually used alone. However, when put together, each of these tools complements the other and fits together like a puzzle. The MERN stack is a comprehensive web and app structure and framework that includes all the libraries, tools, predefined codes, and resources needed for any development process.
MERN is an abbreviation for the main technologies and tools included in this stack, which are MongoDB, ExpressJS, React, and NodeJS. MERN stack is widely known for being easy to use and learn, as well as being a full-stack solution for developers that contains all that they would need throughout the development process.
Components of MERN Stack
To get a better glimpse of the MERN stack, let us break down each component, its role, and how it works.
Starting with the M, MongoDB is the first component. As any app, website, and software always receives input data from users, developers would definitely need somewhere to store such data. In this case, MongoDB is the one responsible for this duty. MongoDB is a great dataset tool that is responsible for storing every piece of input data. What makes MongoDB ideal and effective is that it is very reliable, secure and can process and store large sets of data.
The next component is ExpressJS. ExpressJS is responsible for building and establishing the back-end systems for websites and apps. It is the recipient of all the requests of users, and it is capable of handling them efficiently and effectively.
What is MEAN Stack?
Just like the pile of tools that are present in the MERN stack and help developers experience an easy and swift app and web development journey, the MEAN stack does the exact same, with a few differences in the tools and technologies used. The MEAN stack is more specialized, as it is used often to develop web applications, which is one of the three types of applications a developer could create.
MEAN is an abbreviation of the four components in this stack, which are MongoDB, ExpressJS, Angular, and NodeJS. And yes, the MEAN and MERN stacks share three of the four components, but do they have the same roles?
Components of MEAN Stack
MongoDB serves the same function that it does for the MERN stack. That would be functioning as a no-SQL database tool that immediately stores the input data incoming from users.
ExpressJS is also the same. It is responsible for establishing the back-end system and structure to process and handle incoming requests.
Now that we have come to the main difference that sets the MEAN vs MERN stack stacks apart. Angular also helps one establish the front-end part of web apps. The same role as ReactJS. However, through Angular, a developer could create much more dynamic and intuitive user interfaces. Unlike React, it uses HTML syntax for creating those interfaces.
NodeJS also has the same function in the MEAN stack, which is running and generating the server-side code. This is to ensure the applications and websites have robust and proper functionality and smooth operation.
Exploring the Differences Between MERN and MEAN Stack
Whether you go with the MERN or MEAN stack depends heavily on the complexity of your project. Angular is a good option to consider if the front end of your project has to be more complex and feature-rich. The powerful set of tools and functionalities provided by Angular simplifies the development of elaborate web apps. React, on the other hand, may be preferable if your project’s front end is less complex and you’d like a lighter, more adaptable solution. User interfaces can be rendered and updated quickly using React thanks to its component-based architecture.
Scalability and Flexibility
Consider the MERN and MEAN stacks’ scalability and flexibility when weighing the differences. Despite their distinct characteristics, both stacks are very scalable to meet growing demands. Through the utilization of cloud-based services, scalability is attained in the MERN stack, allowing for effortless demand-based application expansion. If your user base expands, you can quickly scale up to accommodate the influx of new visitors. The MEAN stack, on the other hand, is scalable because it uses horizontal scaling, in which additional servers are added to handle increased traffic. As a result, there is more flexibility for accommodating heavy traffic. When deciding on a stack, think about the project’s scalability needs and how easily you can fulfill those needs with each option.
The choice between MEAN vs MERN stack fully depends on you. Before deciding on either, you should consider your requirements, skills, knowledge, and features. Do comprehensive research on the technologies, tools, and resources used. This will help you make well-informed decisions and avoid starting with one of the methods that could turn out poorly. Both stacks have their distinct characteristics, pros, and cons. If you are going for a more edge, complexity, and dynamic interface, then MEAN is your ultimate choice. However, if you are looking for a more simple solution where you can achieve minimal features, functions, and interface, then MERN is your go-to. However, both will also accomplish some exceptional outcomes and help you develop robust applications. So, whether you choose the MERN or MEAN stack, you can ensure a great outcome.
