It contains four technologies:
MongoDB – open source NoSQL cross-platform database written in C ++. It stores data in a key-value pair using the binary data type. This is an excellent choice for a database system in which you need to manage high-volume tables.
Express.js – web framework for developing applications on Node.js. Many people call it a standalone development environment, but de-facto it is a tool for Node.js, since in almost all cases they are used in pairs.
Angular.js is front-end framework
from Google, which today is considered one of the best in its field. It allows you to use HTML as a template language. Thus, you can extend the HTML syntax to express the main components of the application and optimize its functionality.
MEAN stack concept
When one or even several unrelated technologies are used for development, the concept of work is initially understood. But when it comes to an approved set of tools, many for some reason start to get confused, although they clearly know the functionality of each component.
The concept is as follows:
1. Angular creates a query.
2. Node handles it.
3. Express receives data using Mongo and sends it to the Node.
4. Node creates the response to the request.
5. Angular displays the desired user result.
There is nothing difficult in the work of this stack: each tool is solely responsible for the actions for which it is intended by default.
Why choose MEAN
In a world of advanced technology, web application development is more than just modernity. Combining several tools into a single unit for easier development of first-class products is a common phenomenon. One of these stacks is LAMP (Linux, Apache, MySQL, PHP language
Previously, this stack was the best, but today not only a high-quality server part is needed, but also a useful user experience, as well as a dynamic design. MEAN is much better at this task thanks to more advanced technology.
MEAN is endowed with simplicity and great structure flexibility, which greatly simplifies the development process. Its components are enough to provide all the main components of any application - from the database to the server part. It forms a holistic mechanism for creating competitive products.
• compatible with all operating systems;
• allows you to develop applications in real time;
• quickly executes requests;
• it is enough to know one language;
• contains ready-made effective modules;
• supports MVC structure;
Types of applications that will be better thanks to MEAN
None technology can be ideal for all cases, because it is a utopia. Therefore, to maximize the benefits of the money spent on development, you need to understand which programs will be successful with MEAN.
These are the applications that transmit information between the server and the user instantly. So the client is in constant contact with the company and receives services without delay, which greatly enhances the reputation of the business.
Among such decisions can be identified:
• applications for online games;
• chat applications;
• video conferencing applications;
• payment applications;
• social networking platforms.
After writing the application, you will need a server to host it. It will process requests and deliver data through network connections. Setting up such a system with hardware will require a significant budget.
Placing an application on the cloud will eliminate such costs and increase your ROI. How does MEAN fit into this concept?
This stack allows you to create easily scalable and flexible applications, which makes them ideal for cloud storage, since they do not contain much unnecessary information. In addition, MongoDB supports cloud storage.
Most useful areas for using MEAN
The above types of applications are found in any area throughout the market. However, MEAN is not the best solution for all business areas at the same time. Its direction is current trends, namely:
• IoT applications;
Each user has certain expectations from the product. Yes, and the entrepreneur has special needs that must be met with respect to the final product, and its development. Why is the MEAN stack so fond of modern companies?
User experience is a separate parameter for assessing the success of an application. It can make the product the most popular or in a second to destroy his reputation. Products developed by MEAN provide:
• fast response time;
• lack of automatic page reload;
• smooth navigation.
In addition, there are other benefits that depend on the requirements of the business. But these four factors are present in any application. Excellent user experience is exactly what attracts the most attention of the client to the business.
Again about the satisfaction of the whims of users. The plenty of smartphones on the market has made the need for responsive website design almost the first in the list of requirements. MEAN is good because it allows you to develop high-quality single-page applications that are easier to resize the screen.
Business is planned for a long period, accordingly, applications must be prepared for the future. Scalability plays a major role in this plan.
Scalability refers to the ability of an application to process more data without losing performance. The more successful the business, the more data the application receives daily.
The M and N components help you create applications that will last for years. MongoDB is a database that has cloud storage. Thus, even if the amount of information increases significantly, data management will remain just as effective. Node.js makes applications
more flexible by providing the ability to tune in to new user requirements in a few simple steps.
One language eliminates the need to delve into additional development tools, which allows you to quickly get started and create an application framework.
All components support JSON. This means that the developer does not need to rewrite or format the data so that the user has constant access to the information.
Isomorphic coding.This means that, if necessary, a developer can safely transfer already written code from one framework to another without major changes. Reuse does not affect the functionality of the application. Budget development
Open source.This means that the technology is free, and also have many ready-made solutions on the network. Thus, the developer will spend less of his own money on writing code, and therefore the cost of the application will be less.
Reusing code means that the developer does not need to rewrite every code. Accordingly, it is possible to pay less money, since payment occurs in proportion to the work done.
