Introduction

The MEAN Stack Application is an open-source collection of JavaScript technology that has earned significant popularity. Using MEAN stack components can help in building complex full-stack web applications, thus making it an excellent option for front and backend development.

In this article, we’ll learn about four components of a MEAN Stack development, with its Use Cases. Moreover, we’ll also understand what makes MEAN the best choice for a full-stack application.

Firstly, let’s understand what MEAN Stack Development is.

What is MEAN Stack Development?

The MEAN stack is a set of tools for building websites and web apps, all based on JavaScript. It gets its name from four main technologies it uses:

• MongoDB: This is where your app's data lives. It's a kind of database that's good at flexibly storing lots of information.
• Express(.js): This works on the server (the powerful computers that run websites) to help your app talk to the internet smoothly.
• Angular(.js): This helps create the part of your app that people see and interact with within their web browsers.
• Node(.js): This is also for the server, making it possible for your app to handle many users and tasks at the same time.

People have also made variations of the MEAN stack by swapping out Angular for other tools like React (making it the MERN stack) or Vue (making it the MEVN stack).

The MEAN stack is a popular choice for developers because it uses JavaScript everywhere, making it easier to build and manage web applications.

Before moving ahead towards understanding the advantages and drawbacks of MEAN Stack, let’s first understand What activities does a MEAN Stack developer perform?

What does a MEAN stack developer do?

By using MEAN Development, a developer can build a dynamic web application and website through free and open-source technologies.

MEAN Stack developers use a set of four technologies to build up a MEAN Stack to develop varied web applications. This role isn’t different from that of a full-stack developer, i.e. they also work on both front as well as backend systems. When you Hire MEAN Stack Developers you need to focus on all the below-mentioned functions that they perform

Some of the other responsibilities and expectations from a MEAN Stack developer includes:

• Experience in working with each layer of MEAN Stack, i.e. MongoDB, Express.js, Angular.js and Node.js
• They should also be comfortable in working with jQuery, PHP and Symfony
• Thirdly, they are also responsible for testing varied web applications
• They also perform deployment activities to deploy web applications
• They are responsible towards creating various modules
• A MEAN Stack developer is also responsible for designing databases.
• Lastly, they are also responsible to integrate APIs

Now, let’s understand what are the advantages of MEAN Stack

What are the Advantages of MEAN Stack

The MEAN stacks make building full-stack, real-time web applications possible. Let’s understand a few of its advantages.

• JavaScript Simplicity

The MEAN stack lets you use just JavaScript for both server-side and client-side, making it easier to handle coding and speed up the development process.

• Easy to Grow

It's built to handle growth well. You can easily add more power by connecting more servers, especially since it's designed to manage data efficiently across several machines.

• Supportive Community

There's a big group of developers who use and improve MEAN, providing help and sharing resources. This means you have a lot of tools and help available, making it easier to add new features to your app.

• Simple to learn

Learning the MEAN Stack is easier and can save businesses time and money on training. JavaScript is widely known, and there are many resources available to help coders learn the specific technologies of Express.js, Node.js, AngularJS, and MongoDB.

• Secure

The MEAN Stack is very secure, which is important for apps dealing with private information. MongoDB makes it hard for hackers to access data due to its unique storage model. AngularJS helps keep data safe by encrypting it and checking inputs to prevent unauthorized access.

Now, let’s understand what are the drawbacks or disadvantages of MEAN Stack

What are the Disadvantages of MEAN Stack

Despite MEAN Stack being beneficial for many, it is not preferred by everyone. MEAN Stack has its own set of drawbacks. Let's understand a few of them in this section.

• SQL Database Compatibility

The MEAN stack prefers MongoDB, which doesn't use traditional tables like SQL databases. If your project needs a strict way of organizing data, MEAN might complicate things.

• Handling Heavy Tasks

Node.js in MEAN processes tasks one at a time. This is efficient for most tasks but can slow down if the work gets too heavy or complex.

• Learning Curve

Starting with Angular and MongoDB can be challenging. Angular is feature-rich and updates often, while MongoDB's flexible approach to data might be new to those used to SQL databases.

Now, finally let’s jump to the most anticipated section of the article to understand the Use Cases of MEAN Stack

What are the 3 Vital Use-cases of MEAN Stack?

Although MEAN Stack has a few minor drawbacks, it is still preferred as an ideal choice for developing a wide range of applications.

Single-Page Applications

MEAN Stack is efficient in building single page applications, such as an ecommerce application, a CMS, i.e. Content Management System and varied social networking applications.

The SPAs must offer a dynamic personalized update without requiring an end user to reload the page. MEAN Stack’s Angular component ensures the creation of this view using its component-based architecture, templating, and a two-way data binding. Moreover, it also allows you to customize your UI as per users’ preferences and updates in real time based on its interactions with the page.

Further, by combining Angular with Express.js you can enhance the user experience. Here Angular will dynamically render the UI, whereas Express.js will provide routing and middleware to handle client requests and communicate with the database or an external service.

Real-time Web Applications

A MEAN is ideal for building any real time web application, like a gaming site, chat applications  and collaboration tools. Node.js, a component of MEAN stack, helps real-time data processing using an asynchronous I/O model. Moreover, it also provides web sockets to enable a seamless data transfer between the client and the server without the need of any multiple HTTP requests.

This connection enables applications to deliver live messages and updates. When the user is sending the message in a chat application, and when the server immediately broadcasts it to an intended recipient they would experience an all-but-invisible benefit of a persistent connection.

Data-Intensive Application

MEAN is well-equipped to manage the demands of data-intensive processes which drive applications like ecommerce platforms and finance software.

Node.js is an efficient option to process and manage a larger amount of data without impacting the performance. Moreover, MongoDB is efficient in handling large and complex data sets. It can also manage complex data sets, not only this it can also read-and-write operations to the databases that are crucial functions for applications which store, update and retrieve data faster.
