What is the MEAN stack, and Major Reasons to Choose it for your Next Project?

Everyone aspires to reach their goals in a single go. Even if you’re building a new application, you need to ensure everything is done right the first time. Even if it’s impossible for you to succeed, you may still give it your best go! You must have a robust backend that has been built utilizing a group of technologies that reduce development time and streamline resources to achieve this.

Developing mobile and web apps has never been easier or more efficient than it is now, thanks mainly to the proliferation of hybrid technology. An example of this is the MEAN stack built using this technology.

MEAN Stack Development: What Is Mean Stack, and How Does It Function?

What is mean stack - The development of web-based applications using the MEAN stack is a combination of Javascript-based technologies. As a result, M-MongoDB acts as the database system, E-ExpressJS serves as the backend web framework, and A-AngularJS serves as the frontend framework. To run from one client to another, Mean stack solutions use JavaScript.

The Mean Stack Architecture may be studied to learn more

AngularJS development is JavaScript’s client-side language, and it is used to build web applications. Consequently, AngularJS is the first to respond when a user sends a request.

Step two involves sending the request to Node.js. Server-side programming is a common term for this programming language.

Phase 3 (ExpressJS) is when the request performs a database request after step 2.

MongoDB receives a request from ExpressJS and responds with the data it requested. ExpressedJS gets the answer and processes it.

Similar to ExpressJS, NodeJS delivers the response to the AngularJS application through NodeJS.

What is each component of the MEAN Stack, and what do they contribute to the overall system?


An open-source and free NoSQL database, MongoDB is designed for cloud-based applications. It uses an object-oriented structure instead of a relational model.

The application’s data is stored in MongoDB, which is part of the MEAN stack. When an object is moved from the application to the database and back, it doesn’t need to be translated since both the application and database are written in JavaScript. The application can push and pull the back end and database without a hitch.

MongoDB is lauded for its ability to grow in both storage capacity and speed as a database. You don’t have to refresh the whole table using MongoDB if you want to change a single field. Additionally, MongoDB is well-known for managing massive amounts of data while retaining rapid data access. With a few clicks, you may dramatically increase the resources available to your database, making it suitable for applications that sometimes see surges in traffic.


A Node.js web application framework called Express is available for use with the Node.js platform. Easy-to-use and feature-rich, it hits the right balance.

When we talk about Mean stack solutions - as a part of the MEAN stack’s backend, Express ensures that all data exchanges between the frontend and the database are completed on time. Intended for use with Node.js, JavaScript is preserved across the stack because of its regular use of it.

Express is a lean framework, which means it’s designed to get things done quickly without adding extraneous bloat to your project. However, the phrase “minimalist” should not be confused with the term “featureless.” Express’ error handling and templating features are among the best in the business.

Express also uses the CommonJS module standard to prevent accidental overwriting of variables in the common namespace, which is a good feature. Defining and redefining a variable that you have defined is not feasible. The use of JavaScript closures may help prevent a costly and time-consuming error from happening in the first place.


AngularJS, JavaScript Google’s front-end framework, is by far the most extensively used, even though it is not the only one. For frontend JavaScript development, it is a de-facto standard. The AngularJS framework is used to create a JavaScript web application.

When developing an application’s user interface, the MEAN stack includes the AngularJS framework. Your application’s components are built using JavaScript to guarantee that information flows seamlessly between them.

It’s not by chance that AngularJS is the most widely used JavaScript frontend framework. It is the perfect front end for building cloud-native applications because of its high performance and easy-to-use templates and its ability to produce for both desktop and mobile platforms at the same time.


An asynchronous event-based JavaScript framework, Node.js handles several connections at once. It’s open-source and free. Thanks to this technology, a cloud-based application may readily expand in response to demand. Most well-known websites use Node.js as their backend technology.

The MEAN stack is built on top of Node.js. AngularJS and Node.js are a natural fit for Express, which is built to run on top of the Node.js platform. Because Node.js has a built-in web server, moving your MongoDB database and application to the cloud is a breeze.

Node.js’s greatest strength is in its capacity to scale. Rapid response to changes in demand is critical for cloud applications. Is there a benefit to having practically infinite computer resources available only after your users log off? Because of the framework’s single-thread architecture, it will be possible for the application to provide a smooth user experience over a wide variety of connections while still being able to grow its resources as needed. Up to one million connections may be supported concurrently by Node.js.

A considerable number of low-resource queries are better for Node.js than a small number of resource-intensive ones. One thread may be able to avoid deadlocks, but a massive process might still crash the system, affecting all users.

A key selling point of Node.JS is its capacity to handle millions of simultaneous connections.


According to the project’s website, a web stack called MEAN is mainly used for cloud-hosted applications. Applications built on the MEAN stack are well-suited to cloud computing because of their flexibility, scalability, and extensibility. In addition to the web server, the stack includes a database that can be expanded on demand to handle temporary spikes in demand. MEAN software is introduced in this scenario, which has been intended to take advantage of the cost reductions and performance benefits that the cloud provides.

Web developers have relied on JavaScript for many years because of its versatility, dynamic nature, and ease of implementation. Since just a few years ago, has it been possible for programmers to use JavaScript as a backend and database development language? It can decrease the number of development teams needed since MEAN is written in a single language. Using MEAN, you don’t need to hire a team of experts to create the different parts of an application. Using a single pool of JavaScript developers instead makes it feasible to operate flexibly, as and when necessary. The ability to reuse code throughout the whole application is another benefit of using JavaScript as the language of choice.

Examples of Typical Situations

It’s not suitable for every application, but the MEAN stack has a handful of uses where it excels. To create cloud-native applications, among other things, it is a suitable choice because of its ability to manage several concurrent users. Because of its frontend architecture, AngularJS is a good choice for building single-page apps (SPAs), which are programs that give all of their information and functionality on a single website. MEAN may be used in a variety of ways, including the following:

  • Calendars
  • Keeping a record of your spending
  • News aggregation using the Internet
  • Providers of mapping and navigational assistance

What distinguishes MEAN Stack Development from other methods of software development?

MEAN Stack Development has the following characteristics:

Straightforward and fast to grasp

A single programming language, such as JavaScript, allows for the much faster creation of online apps and web pages.

Developers that participate in the community

The MEAN Stack uses JavaScript, the most popular programming language globally, as a backend component. Thus, it also benefits from a vibrant development community, making it easier for all stakeholders to develop a workable solution.

The MEAN Stack’s Flexibility

Several web-based applications may benefit from MEAN Sack’s JavaScript programming language, including but not limited to social networking sites.

When creating with the MEAN Stack, what are the benefits?

The programming language used by MEAN is a monolithic one

Because MEAN Stack uses JavaScript, all of the technologies it incorporates are also developed on the JavaScript platform. Programming the application is made more accessible since JavaScript handles everything from database administration to frontend and backend management. There is no need to look for extra engineers with specific language or server knowledge as a consequence.

Aside from the fact that MEAN is open source and free, it’s also relatively cost-effective

JavaScript, an open-source programming language, is used by almost every technology in the MEAN Stack. Thus, the platform is free and open-source as a consequence of this. Downloading and using it are free of charge. You won’t have to pay any licensing fees for Mean stack web development companies.

On the other hand, MEAN requires fewer developers than the LAMP stack. When utilizing the LAMP framework, you’ll want JavaScript, PHP, and MySQL-savvy engineers.

MEAN has much scalability

Once a program is complete, it may be rapidly and easily tested on the cloud by the developer. MEAN is very adaptable since it enables you to. construct, b. test and c. distribute the application without any problems. In addition, MEAN makes it easy to add extra fields to a form after you’ve added the first one.

The developer may begin testing the app on a cloud platform with relative simplicity after the conclusion of mean stack application development. MEAN Stack streamlines and accelerates software development, testing, and deployment. Most other systems are not as efficient as this one, yet it still has a competitive advantage in many areas. When developing a project, JavaScript is a popular programming language due to the ease with which team members may switch roles and handle issues.

Isomorphism holds for the MEAN function

MEAN simplifies the process of writing isomorphic programming. Code may be easily transferred across different frameworks utilizing the MEAN programming language. As the name indicates, isomorphic codes may be reused in other frameworks since they are developed just once. In addition, this code runs as smoothly as if it were written in native code. When designing mobile apps utilizing the MEAN Stack, this is one of the most important benefits.

Real-time apps may let you connect with a wide range of customers. User interface (UI) and user experience (UX) are hallmarks of Angular-based internet applications (UX). Many of your favorite companies utilize Angular.JS, which is widely considered to be the best frontend technology. The framework also provides support for the Model-View-Controller architecture, which ensures that user interfaces are of high quality.

MEAN’s user interface is intuitive and well-designed

Angular is well-known in the market for its fantastic UI and UX in any web or mobile application. The fact that Angular.JS is generally recognized as the best frontend technology available means that many of the well-known companies you know and love utilize it. A high-quality user interface may be provided to its customers because of the MVC (Model-View-Controller) architecture that it supports.

  • Reusable and efficient, MEAN is an excellent tool.
  • Because MEAN uses Node.JS, its performance and reusability have been improved.
  • The design of non-blocking JS is advantageous. As a JavaScript framework, Angular.JS provides the benefits of reusability, testing, and simplicity of maintenance.
  • MEAN is a cloud-friendly programming language.

As a result of using publicly accessible repositories and libraries, the overall cost of Mean stack app development is reduced. MongoDB uses less disc space than other databases because of the app’s reliance on the cloud.

MEAN stack development may be learned by anybody, regardless of their programming experience. It is easy to learn, understand, and put into practice in the development process. Both Node.js and Angular.js apps use JSON files as a data communication standard. Mean stack development services help to make data communication inside the system both efficient and straightforward.

For programmers, MEAN streamlines the development process

Because it is built on top of JSON, the MEAN stack also lends itself well to developers. The data transfers across layers are smooth and straightforward to handle when the developers utilize MongoDB or Angular. A large amount of time is saved due to the isomorphic nature of MEAN’s features by the Mean stack developers.

The JavaScript programming language is used to finish the Mean web development process. JavaScript, a multi-paradigm high-level programming language, is frequently used in data management and recovery applications. All-in-all, it’s an excellent framework for a Mean stack developer since it allows for fast backend answers and allows the application to grow as required.

JSON may save much time when making changes to the existing MEAN stack formats. As long as JSON supports external APIs, developers may rapidly and easily create new features that benefit customers. On the other hand, JSON makes it easy for PHP developers to get their hands on it.

Continuity-free modules

Node.js allows the MEAN stack to control an almost infinite number of modules. Users may also access many JavaScript modules, which may prove to be quite beneficial to some of them. Because of the pre-defined outputs provided by these libraries, programmers are spared the time and effort of designing extended programmes to do specific tasks. In addition to being very quick, these libraries ensure that the code as a whole is structured correctly. In general, libraries save time for the programmer and speed up software development.

One of the most extensively used programming languages globally, JavaScript, aids developers throughout the world and enhances the value of development companies. A global community of people dedicated to helping other medium-stack web developers succeed can be found worldwide.

The MEAN stack development framework relies heavily on NodeJS, and it is responsible for ensuring that the framework operates at its best. An interactive web app with an intuitive user interface may be created using its high-quality output. Because it’s easier to learn and understand and because it provides better outcomes, NodeJS is a superior programming language to others. This framework is the most widely used to construct high-performance server-side solutions and tools. You may be able to find developers that can aid you in creating web applications using this framework.

MEAN stack initiatives benefit from using JS, short for Java Server Pages, by companies. The management team has no ambiguity in this case since all of the dynamic teams speak the same language.

Consistency of language

You write all of the code for the development process in JavaScript, from the client-side to the server-side, whenever you work with MEAN Stack technologies. Both frontend and backend developers will find MEAN stack development to be a simple learning process.

Developers no longer have to spend time worrying about the compatibility of their code at multiple application stack layers. As time passes, the development process becomes more streamlined and well-organized.

It’s easy to understand, assimilate, and apply throughout the mean web development process in and of itself. Developers need just know and comprehend JavaScript (ECMA-Script) to design all of the components of a website, from its display layer (Angular) to its database layer (Postgres) (MongoDB).

A vast collection of books

Node.js has an extensive library of JavaScript modules, making developing web applications using Node.js easy and uncomplicated.

A Debugger Is Quite Straightforward

You can monitor the execution thread in the MEAN stack since it uses a single programming language that can be applied to all levels. Debugging the data flow may be done using a standard set of free, open-source tools that developers can quickly identify and use.


From basic single-page applications to sophisticated advanced-complicated systems, MEAN provides developers with the appropriate basis for building dynamic apps. When it comes to developing online products and applications, MEAN is the current development strategy of choice for many leading companies.
