What is MEAN Stack?


MEAN is a collection of technologies (MongoDB, Express.js, Angular.js, and Node.js) related to JavaScript and building web applications. The MEAN stack is responsible for developing all website development components, from client/server to database processing. All of these components are based on technology, H. JavaScript. MEAN Stack is a full-stack development branch used by developers to build fast and robust web applications.
What is MEAN Stack ?

If we want to build a dynamic website, the MEAN stack is the perfect choice for us, and the reason is simple: MEAN is easy to use. Additionally, MEAN stack technology is open-source; H. Free to use; With the help of MEAN Stack, we can prototype our website very quickly and organize it easily.

What is a Mean stack?

A MEAN stack developer is someone who only knows certain areas. MEAN batch development refers to the development process that integrates into these specific technologies: MongoDB, Expressjs, AngularJs, NodeJS.

MEAN Stack is a collection of technologies that you can use to build a full-stack application.

  • M stands for MongoDB (without SQL database)
  • E stands for Express (a structure via Node)
  • Stands for Angular, a front-end structure
  • N stands for Node, a back-end structure

Two main advantages of the MEAN stack are its scalability and the fact that it only uses JavaScript. Since they are all JavaScript, a good MEAN stack developer should have extensive knowledge of JS.

The main functions of MEAN stack technologies are:

  • Angular JS: accepts requests and shows results to the end-user
  • NodeJS: manages client and server requirements
  • Express JS: send requests to the database and return a response
  • MongoDB: store and retrieve data.

As you can see, the proper name for this tech stack should be ANEM, as it captures your stacking order, but MEAN is more memorable.

A MEAN batch developer uses only a specific batch of technologies to create a complete batch application.

More and more companies have chosen MEAN Stack Developers as their preferred workforce because they can build a full-stack application, and their Mean salary is often lower than that of a full stack developer. Let’s talk about the responsibilities, requirements, and salaries of the Mean stack developer.


MEAN is an open-source web stack used primarily for building cloud-hosted applications. MEAN stack applications are flexible, scalable, and extensible, making them perfect candidates for cloud hosting. The Stack contains its web server so it can be easily deployed, and the database can be scaled, if necessary, to accommodate temporary peaks in usage. A MEAN application arrives in the optimized world to take advantage of all the cloud’s cost savings and improved performance.

JavaScript is a popular language for front-end web development – it’s flexible, dynamic, and easy to use. However, this has only been a back-end and database development option for several years, allowing developers to build applications using JavaScript from end to end. Since all parts of MEAN use the same language, you can optimize your development teams. MEAN eliminates the need to hire different specialists to develop each part of an application. Instead, you can use a single group of JavaScript developers to work adaptively when needed. JavaScript normalization also provides the ability to reuse code in the application, reducing unnecessary reinvention.

Use Case

While the MEAN battery is not perfect for all applications, it excels in many uses. Its scalability and ability to manage concurrent users make it an excellent choice for developing cloud-native applications. The AngularJS front-end framework is ideal for developing single-page applications (SPAs) that provide all information and functions on one page. Here are some examples of using MEAN:

  • Calendar
  • Cost tracking
  • News aggregation sites
  • Mapping and location search

What is MongoDB?

MongoDB is written in C ++ and is an open-source database with multiple platforms. In MongoDB, storing data (in key-value pairs) is more flexible than in other databases, and here the type of data stored is binary as in JSON.

MongoDB is a document-oriented NoSQL database, i. H. Fields may vary from document to document, and the data structure may change over time. A document in MongoDB is similar to an object in OOPS.

If we have large tables with a large amount of data (up to millions), we can easily manage them using MongoDB. Inserting new fields in MongoDB is very easy, as the entire table is not updated when new data fields are inserted. This makes MongoDB the perfect choice for a database system. Additionally, MongoDB allows us to build an entire web application using a single scripting language, JavaScript. This is the most significant advantage of all.

As mentioned above, MongoDB is an open-source database; H. It is free to use. There are many versions of MongoDB: versions released before October 16, 2018, are released under the Affero General Public License (AGPL). Subsequently, the latest versions will be released under the Public Server License (SSPL) v1. Additionally, all fixes from previous versions are also released under SSPL.

Why learn MEAN Stack?

There isn’t much we can do on the web without the MEAN stack. It is a complete package. Also, if we are familiar with JavaScript, it is straightforward to develop an entire website, and we do not need to learn different languages to develop the website. Learning the MEDIUM battery thus increases employment opportunities.

MEAN stack architecture

Now let’s take a look at the robust architecture of the MEAN stack. As we have already learned about MongoDB, Express JS, Angular JS, and Node JS, we will now see how these four elements contribute to the MEAN stack architecture.

o Angular JS: Angular is responsible for receiving clients’ requests and displaying results retrieved by Node.js to clients.

o NodeJS: manages client-side and server-side requests.

Express JS: Express sends the request to the database, which is processed by MongoDB, and after retrieving the recovered data, Express sends the response back to Node.js.

o MongoDB: MongoDB stores and retrieves data. Therefore, it is used to manage the database.

Benefits of MEAN Stack

  • MEAN is a JavaScript-based tool: as explained above, one language is used, JavaScript. This is why developers like to use MEAN because they only need to write code in one language.
  • Client-side code and server-side code can be easily exchanged:

As we know, MEAN stack uses only one language as its base language, namely JavaScript, so working with server and client-side requirements are very easy and can be switched if needed. MEAN stack developers don’t need other server-side tools like Apache or LAMP Stack because MEAN already provides Node.js, which acts as a web server.

  • MEAN is open source technology: all technologies in the MEAN stack are open source technologies, that is, they are available for free. Thus, we can easily access public repositories and libraries, making the development process more accessible and cheaper.

Since it is an open-source technology, most of our doubts can be quickly resolved. The leading application developers have already published answers to the most common questions and problems encountered while using it.

  • MEAN is cheap: if we look at it from a business perspective, the MEAN is cheap technology. Organizations don’t need to hire many specialists to perform a single task, as a single full JavaScript developer would be enough to develop a full project for any business. This means that you can save a lot of time and money in this regard.
  • MEAN supports MVC architecture: The MEAN stack can support MVC (Model-View-Controller) architecture. This gives developers the freedom to handle a wide variety of programming languages.
  • MongoDB is cloud compatible: MongoDB is the ideal solution if our application needs to implement functions in the cloud. This means that we can quickly implement cloud-related technologies ourselves.

MEAN battery components

MEAN is an abbreviation for MongoDB, ExpressJS, AngularJS, and Node.js. Each of these components has a specific use.

  • MongoDB: It is a schema-less NoSQL database system. MongoDB stores data in binary JSON format, which simplifies the transfer of data between client and server.
  • ExpressJS: is a web application framework for Node.js. It allows you to build server applications in Node.js and is a back end application that connects the front end and databases.
  • AngularJS: It’s the latest technology on the Stack. It is a JavaScript framework that controls the behavior of various elements displayed on web pages.
  • NodeJS is the JavaScript runtime environment. It is used to run JavaScript on a computer instead of a browser.
