What is MEAN stack Developer?

MEAN stack developers using the four technologies that comprise the MEAN stack create web applications. Someone who is an expert just in a few specific fields is known as a Mean Stack Developer. They must create front- and back-end systems, create new modules and features, carry out unit testing, and collaborate with the web app team. Mean Stack Developer jobs include designing and maintaining large, complicated databases, setting up and integrating development environments, and identifying production and non-production application issues as part of the deployment.

Qualifications like B-tech, M-tech, MCA from reputed colleges are required to get Mean stack developer jobs with a good salary package. You can find various online sites which provide Mean stack developer courses but there are only some prominent institutions like 3RI Technologies, which gives placement assistance with MEAN Stack Online Training.

What is MongoDB?

The C++-based open-source document database MongoDB offers high performance, high availability, and scaling. The simplest way to quickly deploy, run and scale MongoDB in the cloud. To manage huge tables with millions of data, MongoDB is necessary. MongoDB is necessary to manage Large-sized tables with millions of records that can be stored in MongoDB, making it simpler to update an entire application using just one program, such as Javascript.

What is Express.JS?

A Node Js web application framework called Express offers a variety of features for creating web and mobile applications. It is used to create web applications that are a single page, multipage, and hybrid. Because it is quick, inexpensive, simple to understand, and fast, the Express framework for Node.js was developed. Some companies that are using Express Js are Netflix, IBM, eBay, uber, etc. This framework to support templates uses the Pug engine.

What is Angular JS?

An extremely potent Javascript framework is AngularJs. Projects involving single-page applications use it. AngularJs is an open-source, cost-free online application that is utilized by tens of thousands of developers worldwide.

Google maintains AngularJs. A simple HTML language has been taken into consideration for template design in AngularJs, and the application’s syntax is still HTML. This framework’s primary objective is to introduce Model View Controller (MVC). MVC makes the development and testing process easier.

What is Node JS?

Developers may build web servers and web applications using Node JS. Written in C, C++, and Javascript, Node Js. It serves as a backend service for applications that use javascript on the server. The Chrome v8 engine in Node Js transforms Javascript code into machine code. It is swift, light, extremely scalable, and data-intensive. It is swift, light, extremely scalable, and data-intensive.

MEAN stack components

Angular.js front end

On top of the MEAN stack is Angular.js, the self-described “JavaScript MVW Framework” (MVW stands for “Model View and Whatever”).You can create dynamic, interactive online experiences far more quickly and efficiently using Angular.js than if you were to construct them from scratch with static HTML and JavaScript (or jQuery). This is so that you may add metadata to your HTML tags using Angular.js. All the features you would anticipate from a front-end JavaScript framework, such as form validation, localization, and back-end service interaction, are included in Angular.

Express.js and Node.js server tier

The tier below that runs on a Node.js server is called Express.js. As a “simplistic, unprejudiced, and quick web framework for Node.js,” Express.js claims to be, and it does just that. Strong models for handling HTTP requests, responses, and URL routing (the process of matching an incoming URL with a server function) are provided by Express.js. Your application’s Express.js services can receive GET, POST, and XML HTTP requests (XHRs) from your Angular.js front end. Then, these functions employ promises or callbacks to read and update information stored in your MongoDB database utilizing the Node.js drivers for MongoDB.

MongoDB database tier

Database layer MongoDB Similar to Angular, Express, and Node.js, your application should have an intuitive database if it maintains any type of data, such as user profiles, comments, content, events, uploads, etc. MongoDB can be used to tackle this problem.. You can send JSON documents created by your Angular.js front end to the Express.js server, where it will process them and store them in MongoDB for later retrieval if it is determined that they are legitimate. Once more, if you want to swiftly maximise the benefits of MongoDB, you should check at MongoDB Atlas. You will have access to full database security and integrated cross-cloud scalability with just one click. More about that later on this page.

MEAN Stack Architecture?

The goal of MEAN.js is to create a strong framework that supports daily development needs, helps developers work with popular JavaScript components more effectively, and resolves common problems when connecting to MongoDB, Express.js, Node.js, and AngularJS frameworks. When it comes to front-end and back-end development, the MEAN stack is extremely simple and easy to utilize.On the server and client sides, some systems use multiple languages. We only use one language for client-side and server-side development with MEAN technology.

The four building components that make up the MEAN stack for creating an application are as follows:

AngularJS : AngularJS is a JavaScript-based front-end framework. AngularJS allows us to construct both single-page and dynamic apps in the MVC (Model View Controller) style. It is extremely scalable, light, quick, and data-intensive. It is extremely scalable, light, quick, and data-intensive

Node Js: One server-side framework for creating web applications, like single-page apps and websites that stream videos, is Node.js. It provides us with a rich library of JavaScript modules. Take care of both client and server requests.

Js Express: Express.js is a Node.js web application framework. Express.js is a versatile Node.js web application framework that simplifies the development process. Send queries to the database and receive responses back

MongoDB: A document database called MongoDB stores data in adaptable documents that resemble JSON. Store and retrieve data.

  1. Angular Js is the initial application that processes a request made by the client. A client-side language in javascript is called AngularJs.
  2. After that, the request enters phase 2 which is Node Js. A server-side language in Java script is called Node Js.
  3. ExpressJs makes a database request in the phase that follows.
  4. ExpressJs receives the response from MongoDB when the data has been retrieved.
  5. After that, ExpressJs sends a reply to NodeJs, which then passes it on to AngularJs for display.

When can the MEAN stack be used?

The software tier (Express.js and Node.js), database tier (MongoDB), and display tier (Angular.js) comprise the standard three-tier stack pattern that MEAN adheres to.

When developing a JavaScript application, especially with Node.js, you ought to take a close look at MEAN.

MongoDB uses a JSON-like format for storing data (BSON, a binary JSON extension), defines its query language (MQL) in JSON, and uses an interpreter for JavaScript as its command line interface (CLI). In addition to being simply a JavaScript/JSON data store, MongoDB boasts a ton of sophisticated features including horizontal scale-out support, strong native Node.js drivers, and the ability to index and query deep into JSON documents. With MongoDB Atlas, the cloud-native database as a service from MongoDB’s designers, developing apps for the cloud is even simpler.

Mean is the best stack for Node.js applications, whether of whether you’re creating a microservice, a high-throughput API, or a straightforward web application.

How secure is the MEAN stack?

When utilizing the MEAN stack with Atlas, its embedded firewall, end-to-end encryption, and credentials provide the finest foundation for protecting your MongoDB. Furthermore, the MEAN stack features a clear three-tier separation that should keep your end users from reaching your database layer and business logic when combined with best practices and appropriate network isolation. Because of this, your programme is designed to guard against malicious user behaviour (including port spoofing, query injection, and code manipulation) by default.

Advantages of MEAN Stack

Using a standardized software stack is essential when creating an application from the start. Utilizing a set of compatible tools for building your back end shortens development time and maximizes resource use.

But there’s growing competition in the stack field. There are several possibilities, ranging from LAMP to Ruby on Rails. Every stack has advantages and disadvantages and is appropriate for various projects. There isn’t a single development stack that works for everyone.

The primary purpose of the open-source web stack MEAN is to develop cloud-hosted apps. Because MEAN stack apps are flexible, scalable, and extendable, they are perfect for cloud hosting.

The database can be scaled on demand to handle brief consumption spikes, and the stack has its own web server for easy deployment. An optimized MEAN application hits the market to benefit from all of the cloud’s cost reductions and performance enhancements.

JavaScript is a widely used programming language for front-end web development due to its ease of use, flexibility, and dynamic nature. However, it has only been available for back-end and database development for the past few years, enabling programmers to create end-to-end JavaScript applications. You can optimize your development teams because MEAN is all in one language.

MEAN eliminates the need to employ various experts to develop every component of an application. Alternatively, you can work adaptively, where and when needed, by utilizing a single pool of JavaScript developers. Reusing code throughout the entire application is another benefit of standardizing JavaScript, which helps to cut down on needless innovation.

Here are some reason for using Mean stack technology

  1. It can easily switch between client and server. You don’t need a third party like Apache. The developer can launch the application on the server thanks to NodeJs. Because of this, most people describe Mean Stack as quick and simple.
  2. Mean Stack gives us the ability to accomplish more than just serve as a framework for creating web applications. It is quite adaptable.
  3.  Keep your stack’s language consistent. maintains your application tidy and helps you avoid doing unnecessary background research.
  4. Stack’s technologies are open source, making them accessible and cost-free. This makes it simpler for you to access public repositories and libraries, which makes the development process simple and less expensive. 
  5. You can save documents in the JSON format because MongoDB is a relational database based on components ( Javascript object Notation). However, this is only applicable to small to mid-sized businesses.
  6. It supports MVC design, allowing them to avoid having to deal with a wide range of programming languages.
  7. MEAN creates isomorphic code.

Disadvantages of MEAN Stack

  • First main disadvantage of Man Stack is that you may lose records. You run the risk of losing records that MongoDB has successfully written when network partitioning happens, especially in instances with high load.
  • Inadequate separation of the server’s business logic.
  • Why The MEAN stack is not an effective solution for complex applications.
  • There aren’t any set standards for coding Javascript.
  • Lack of widespread agreement.
  • Relational databases remain unbeatable

Use Cases for MEAN stack    

    The MEAN stack provides superior scalability and user management, making it the ideal choice for developing cloud-native applications. The front-end framework AngularJS is also perfect for developing single-page applications (SPAs), which display all features and information on a single page.

    You can use MEAN to create the following websites:

    ●  Single-Page Applications

    MEAN is an excellent tool for developing single-page applications (SPAs), including social networking, content management, and e-commerce apps.

    SPAs must provide dynamic, frequently tailored changes without users reloading the page. Angular’s component-based architecture, templating, and two-way data binding make creating dynamic views easier. Based on how visitors interact with the website, you may adjust your user interface (UI) in real time to suit their tastes.

    Moreover, you may improve the user experience by combining Angular with Express.js. Express.js offers the middleware and routing to manage client requests and facilitate database or external service communication, while Angular dynamically generates the user interface (UI).

    ●  Real-Time Web Applications

    Building real-time web apps, including gaming websites, chat programs, and teamwork tools, is another great use case for the MEAN stack. Node.js’s asynchronous I/O paradigm makes real-time data processing possible. It also provides web sockets to simplify data transfer between the client and server and eliminate the need for repetitive HTTP queries.

    Apps can send real-time updates and messages thanks to this constant connection. When a user sends a message in a chat program, the server instantaneously broadcasts it to the designated recipient, providing an all-but-invisible benefit of the persistent connection.

    ●   Data-Intensive Applications

    MEAN is also well-suited to the needs of data-intensive processes, which power applications such as e-commerce platforms and financial software.

    Node.js is a good choice for processing and handling huge volumes of data while maintaining performance. Meanwhile, MongoDB excels at processing massive, complex datasets. Additionally, it can read and write to the database, which is essential for applications that need to save, update, and retrieve data fast.
