Outsource Mean Development Services

MEAN, the full-stack development quartet in JavaScript to make web applications. The JavaScript applied at client and server level allows developers to enter into full-stack projects of web application development. MongoDB, Express, AngularJS and Node.js (MEAN) form a complete development stack.

One of the latest milestones in the world of software development   is the new dimension that JavaScript has acquired. Before, all the development in this programming language came from the browser side, centered almost exclusively on the design of the front-end of web projects. But nowadays it is not like that anymore. The developers also apply their advantages to servers and databases.

And why is this aspect so revolutionary? For a simple reason. Now, a developer who knows JavaScript can program a web application from scratch and to the end only with their knowledge in this syntax, without being limited only to the development and design aspects of the front-end. It is a perfect example of the myth of full-stack or rock-star developer, technical profile by which a single developer can take charge of all web development.

A professional who masters JavaScript can put into practice the MEAN development, acronyms that allude to the magic quartet for the creation of web applications:  MongoDB  (database management service),  AngularJS  ( front-end development framework  ),  Node. js  (development environment in the server layer) and  Express  ( framework  for  back-end development ). An all in one with JavaScript .

A simple Google Trends search   shows how the technologies that make up this development package are increasingly popular in the community:

Characteristics of the MEAN quartet

1.-  MongoDB

MongoDB is one of the most used NoSQL databases on the market. Specifically, it is a multiplatform database management system oriented to documents (records or data set) and totally free scheme (it should not be predefined). That means that each document (information about products or customers, for example) may have different attributes than the rest.

Some of its most important technical characteristics are:

– Stores structured, semi-structured and unstructured data .

–  Database management system prepared to  offer scalability, performance and high availability of large volumes of data .

– Agile in both reading and writing processes , under a memory computing protocol. This allows any company to grow rapidly in the number of applications and projects without this implying an increase in development time and therefore a cost increase.

–  It has  a very simple query system , based on JavaScript (specifically in JSON documents), with all the advantages of relational database systems but with better performance.

– It has native replication and fault tolerance , a key element if the project requires high parameters of reliability and security.

– There are  drivers  in most programming languages : C #, C, C ++, PHP, Python, Ruby, Java, Perl …

–  Works on  Windows, Mac OS X and Linux operating systems .

–  It is  open source , under a GNU AGPL license v.3.0.

2 .-  AngularJS :

AngularJS is an  open  source and totally free JavaScript framework , which allows the development of web applications on the client side and uses a Model-View-Controller (MVC) pattern, although it does not do it in a traditional way: rather it is a development pattern of the Vista Model-View-Model type.

Behind its launch and maintenance is Google, so it is a pretty solid solution for the community. Its objective is to  optimize both the development and the testing of the tests in the design process .

This  framework  is designed primarily for the development of single-page web applications (SPAs), that is, the user navigates through the different views of the app without traditional URL navigation. This greatly improves the user experience in two ways: the waiting times and latency in navigation are reduced. The applications are faster and smoother.

The fundamental characteristics of AngularJS are:

– Bidirectional  data-binding system . The Model and the View are always updated in a synchronized manner with any change in the data. This makes a lot of sense for a developer because it avoids having to write code repetitively. Any change in the DOM modifies the Model and any modification in the Model transforms the DOM. That this is automatic is a relief when an application grows in volume.

– It has a pattern of Dependency Injection , which allows the creation of objects in a more useful and simple way for programmers. This pattern allows the separation of the code by responsibilities and the creation of objects in a structure independent of the rest of objects.

–  Any application developed in AngularJS is  compatible with several browsers at the same time . The JavaScript adapts to each of them.

3.-  Node.js

Node.js is a JavaScript interpreter on the server side. Its fundamental objective is that a programmer is capable of developing an application with high levels of scalability in a single machine, although the requests of users and clients do not stop increasing over time. If a company launches an app that in a period of two years grows 100% its number of users and customers, the logical thing is that it has associated a proportional growth in the number of servers. More customers, more cost. Node.js breaks that equation.

In traditional operation, each new connection to the server is associated with the consumption of 2 MB of memory. In a usual system of 8 GB of RAM, the limit for that application would be in the 4,000 simultaneous connections of users. That scenario with Node.js changes completely. Each machine could get to support over a million connections at the same time.

Where does Node.js come from? Google uses the JavaScript V8 engine for its Chrome browser. To do this, the search engine developed a JavaScript interpreter that anyone can download and integrate into an application. Node.js uses that interpreter with a totally different purpose: to  use it on the server side

Some of its fundamental characteristics:

– Asynchronous programming .

– Event-oriented programming .

– Supports the integration of third-party modules  that can extend the functionality of Node.js in the development of web applications.

4.-  Express :

Express is a  framework  on the server side for the development of web applications with Node.js. It is inspired by  Sinatra . It is a fast, flexible development framework with a large community behind, which is always important because of the volume of existing documentation for the development of projects.

Some of its characteristics are:

–  Use  Jade  as a   base framework , but the developer  can incorporate  jQuery  or  Backbone  to increase the functionalities in the development.

– Offers URL Router .

– Accessible creation of APIs .
