MEAN is a user-friendly full-stack JavaScript framework ideal for building dynamic websites and applications. It is a free and open-source stack designed to supply developers with a quick and organized method for creating rapid prototypes of MEAN-based web applications. One of the main benefits of the MEAN stack is that a single language, JavaScript, runs on every level of the application, making it an efficient and modern approach to web development.

WHY LEARN MEAN?
It’s hard to accomplish much on the web without JavaScript, which is the single language that runs the entire MEAN full stack and boasts one of the most active developer communities. Because every part of MEAN programming is written in one language, it allows unique server-side and client-side execution environments. Valued for its versatility in building fast, robust and maintainable production web applications, MEAN is in high demand with numerous startups and employers.

In this world, the procedure of web development is considerably different. Open source web applications have surfaced in order to ease the task of the programmer and help them with libraries, web servers, database system and front-end frameworks. Nowadays, developers are implementing the technologies in such a way that they are more faster and operative web technologies. Over the past few years, with the development of more and more sophisticated and open sources technologies, such applications have experienced a futuristic makeover.

MEAN stack refers to a collection of JavaScript-based technologies used to develop web applications. JavaScript is a dynamic programming language for client-side and server-side web application development. It runs on every level of the application which gives an efficient and modern approach to the web development. MEAN stack does not require a software of its own, it all needs its own web browser for executing a web page or an application. It is a technology built with the best composition of technological mediums. MEAN is an acronym for Mongo DB, Express JS, Angular JS and Node.js. From client to server to database, MEAN is full stack JavaScript.

Mongo DB is a document-oriented database, which is cross-platform and has high performance. It is a schema-less NoSQL database system. Mango DB saves data in binary JSON format which makes it easier to pass data between client and server.

Express JS is lightweight framework used to build web applications in Node and supports MVC Architecture with a little bit of work. It provides many robust features for building single and multi-page web applications. Express is inspired by the popular Ruby framework, Sinatra.

Angular JS is a JavaScript framework developed by Google. It provides some awesome features like two-way data binding. It is a complete solution for rapid and awesome front-end development. This makes programming applications with MEAN stack very effective.

Node.js is a server-side JavaScript execution environment. It is fast in code execution, runs on various platforms and is a platform built on Google Chrome's V8 JavaScript runtime. It helps in building highly scalable real-time applications and concurrent applications rapidly. It can use JavaScript as both front-end and back-end languages.

MEAN Stack offers a modern and effective approach to web development. It can be installed in two ways using the mean.io website and using various Yeoman generators. It is good investment for building fast, strong and scalable applications. It is catching up with the other tech stocks in the market and has already made its mark in the development community. Many companies like PayPal, LinkedIn, Netflix use MEAN stack for their development.

A latest technology to the old-fashioned LAMP/WAMP stack for building professional websites and real-time applications is MEAN (MongoDB, Express, AngularJS, Node.js) stack, which is an open-source software.

MEAN Stack You Want to Know

MEAN is nothing but a rearrangement of code and technology upgrades switching the base platform from Linux OS to a JavaScript run-time which brings Node.js. Node.js allows to work on Windows as well as Linux. It acts as a web server which replaces Apache in LAMP stack. It allows the developer to deploy the application directly to the server instead of deploying to a stand-alone server. Deployment is easier and simpler as such the required version of the web server is clearly defined along with the rest of run-time dependencies. In short, Node.js is far more than a simple server.

Compared to traditional web-serving techniques where each connection (request) generate a new thread, taking up system RAM and eventually maxing-out at the amount of RAM available, Node.js operates on a single-thread, using non-blocking I/O calls, allowing it to support tens of thousands of concurrent connections (held in the event loop). Additionally, it is all based on the open web stack (HTML,CSS and JS) running over the standard port 80. In simple, it is really scalable.

It is very important to think that Node.js is especially suited for applications that require persistent connection from the browser back to the server such as chat programs, interactive games, real-time applications etc. If one is just building an application that does not necessarily need user/server COMMUNICATION, developing with other frameworks would be just fine and will take much less time. Node.js is well suited for applications that have a lot of concurrent connections and each request only needs very few CPU cycles, because the event loop (with all the other clients) is blocked during execution of a function.

Instead of writing more SQL commands, MongoDB gives more time writing map/reduce functions in JavaScript. MongoDB, a NoSQL which is schemaless, document oriented persistence represents a fundamental shift in steadfastness strategy. It will also reduce the complexity of transformation logic, because MongoDB release JavaScript Object Notation (JSON) natively. Consequently, writing RESTful web services is easier than ever.

But the biggest shift from LAMP to MEAN is the move from traditional server-side page generation to a client-side single-page application (SPA) orientation. It runs JavaScript, so you can use the same language on server and client, and even share some code between them (e.g. for form validation, or to render views at either end.)

With Express, you can still handle server-side routing and page generation, but the emphasis is now on client-side views, courtesy of AngularJS. This change involves more than simply shifting your Model-View-Controller (MVC) artifacts from the server to the client. And perhaps most important, you'll move from a page-centric view of your application to one that is component-oriented. MEAN stack isn't mobile-centric. AngularJS runs equally well on desktops and laptops, smartphones and tablets, and even smart TVs. And as the MEAN stack is growing in adoption, a variety of testing strategies have developed and available. With world-class testing frameworks such as MochaJS, JasmineJS, and KarmaJS, you can write thorough, comprehensive test suites for your MEAN app.

The single-threaded event-driven system is fast and simple, compared to traditional Java or ROR frameworks, when handling lots of requests at once. Knowing more about MEAN helps you to play around with the technology!

Mean Stack Technologies

Like other technologies, web technologies also coexist with human race and strive continuously to upgrade themselves in new and finer forms. Surprisingly, many recently launched websites have blown out of existence and replaced by new and finer web applications known for creating everlasting and enthralling user experience. MEAN web development tool is one such technology which has earned a strong reputation for creating scalable and robust websites. The MEAN stack comprises of the following elements: MongoDB (Database), Express (webserver framework), AngularJS (web client framework) and Node.js (server platform).

Developing websites with the help of Mean Development Tools is very advantageous than other tools as it provides greater amount of flexibility than other tools. It feeds upon the JavaScript language for coding which makes integration with other applications quite easy. The vision of the Mean Stack development technology is to enable developers in creating more agile applications with uniform language at all the layers.

MongoDB database shares a remarkable similarity with other databases but it is schemaless which makes additions and deletions quite easy. This aspect and feature of the MEAN development technology eliminates complexities and redundancies while dealing with large amount of data. It is very difficult to deal with data segregated into tables and columns in SQL databases. This function also makes MEAN based development synchronized with cloud and cloud based applications. Therefore, the cloud based applications can be easily created and hosted on the cloud network.

MongoDB is also a good alternative to the JOIN Command. It is true that the JOIN command is a groundbreaking innovation for saving disk space. With the help of this command a user can delete unnecessary fields. The fields can be included whenever a necessity arises. This feature concludes a cheap and clean database. But disk space is quite cheap nowadays and comes with terabytes of memory. So JOIN can be replaced with MongoDB.

Mean web development tool uses Angular JS as web client framework which runs at supersonic jet speed. It is a good option when compared to other frameworks like Apache or Internet Information Services (IIS). Apache and IIS lack multitasking abilities as they both conceive HTTP requests using threads. If the threads are engaged in different types of work than no further requests can be generated and this slogs the server response. Having good speed serves many benefits as today's user are very restless and spend very less time.

During the development stage, the conventional web pages need to be refreshed again and again every time there is a request. So if there is huge data on an ecommerce website then the user has to click 'Next' to go to the next page. At this point, he again views the content he viewed earlier. This creates a bad user experience which can severely hamper the prospects of businesses. The advantage with Node JS in MEAN development is that it runs on only one thread for receiving incoming HTTP requests. It performs operations very instantly as it is capable of receiving threads very quickly. So it manages multiple connections at one single point of time. The PHP fan club might boast about the code libraries developed for leading platforms like WordPress or Drupal. However, Node JS is a complete package manner for which the public libraries are increasing at a flash flooding pace. In the coming days, it is possible that many more platforms will be developed using Node.js.

Another amazing option available with MEAN development stack is Express JS which renders vital resources for executing similar and identical tasks on the website. Its interface is quite simple which allows a user in creating endpoints and managing cookies. Moreover, it helps in creating REST routes; for managing HTTP Header; providing supporting to integrated middleware for effectively managing the requests and responses.

All the critical elements of MEAN web development tools (MongoDB, JS Express, AngularJS and Node.js) speak JavaScript Object Notation (JSON) for transferring data. The fluid data in JSON remains very crystal clear while moving through different layers. JSON eliminates the requirement of reformatting the data again and again for every layer. Whereas, the PHP language which reads the SQL data doesn't support the data at every layer.

The aforementioned are just some of the reasons why the MEAN web development frameworks outperform conventional technologies. It is an aggregate of MongoDB, Express, AngularJS, and Node.js. The transcendent features in this framework help in making powerful and robust websites. In the coming days, it is possible that many more businesses applications will be developed using the MEAN development stack.
