What is MEAN Stack?

A bundle of Javascript technologies used to create web applications is known as the MEAN Stack. What exactly is Mean Stack, then? This JavaScript-based framework is used to create web apps that are hosted in the cloud. It stands for the four technologies that make up the stack and is actually an acronym. Let’s look at it. layered by layer.


M: First, there is MongoDB, which increases flexibility and accessibility by making it simple to transfer data from clients to servers.

E: E stands for Express. This is a flexible Node.js framework used to build web applications. Web applications can include multiple pages in addition to a single page. 


A: Angular is a structural javascript framework. It creates web applications quickly and efficiently. Angular is developed by Google.


N: Building network apps with Node(.js), which was influenced by Twisted in Python and Ruby’s event machine, It is an environment for server-side JavaScript execution.

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?

It is extremely scalable, light, quick, and data-intensive. It is extremely scalable, light, quick, and data-intensive.

Node Js: Take care of both client and server requests.

Js Express: Send queries to the database and receive responses back

MongoDB: 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.
