Introduction to Mean Stack
The MEAN software stack is a popular set of technologies for creating websites. It consists of MongoDB, Express.js, AngularJS, and Node.js. Each of these items provides vital features and time-saving tools for website development. Although another popular set of technologies known as the LAMP stack maybe some developers’ preferred stack, this article will outline precisely why you will find more success with MEAN stack development.
Basic Things you will Study in this Tutorial:
•Advantages of Mean Stack
•Components Involved in Mean Stack
•Some additional Benefits
•Applications
Advantages of Mean stack
The advantages of the Mean stack were discussed below.
•Highly Flexible.
•Cost Effective. Using MEAN is cost-friendly to business.
•All kind of technologies that make use of MEAN because it is open-source and freely available for use.
•Easy switch between client and server.
•Exemplary for real-time web applications.
•Time-Saving.
Components of Mean Stack
The various components involved in Mean Stack
MongoDB:
•MongoDB might be a document-based on the open-source database. MongoDB may be a leading NoSQL database. It provides high performance, high convenience, and automatic scaling. MongoDB information is written principally in C++. It’s drivers and client libraries are generally written in their own respective languages, though some drivers use C extensions for higher performance. MongoDB differs from relative databases as a result of it’s a schema-less database. Such information bases sometimes have lower transaction safety however they are in quick accessing data and scale higher than relative databases.
•MongoDB stores valuable data as documents. Therefore it is said to be a document-based database. A document may be a data structure that stores in the form of data in field and value pairs. The format of MongoDB documents is just like JavaScript Object Notation (JSON). The values of a field could be an easier value, array, and other documents. MongoDB uses BSON format to store the information into a document.
Express.js:
Express.js plays a vital role in the MEAN stack, as it works hand-in-hand with Node.js to communicate with the server, establish routes that determine what happens at each URL and create a networked application using JavaScript. It is an easy-to-use back-end framework that allows you as a MEAN full-stack developer to follow best practices in RESTful routing or simply create a web application quickly. Using Express.js will provide you with a useful skill beyond the MEAN stack, as Express.js can work with databases other than MongoDB, as well as a wide variety of template engines including EJS and Jade.
Angular:
Angular is an open-source, JavaScript-based client-side framework that helps us to develop a web-based application. Angular is one of the best and most popular frameworks for developing any Single Page Application or SPA Applications.
The main benefits of using Angular:
•Angular modifies the page DOM directly instead of adding inner HTML code which is faster.
•The Data binding does not involve on each control or value change but at some specific points of the JavaScript code execution. It tries to improve the performance, as a single bulk Model or View of update which can replace the hundreds of cascading data change events.
•There is no need to use observable functions. Angular analyzes the page DOM and builds the bindings based on the Angular-specific element attributes.
•Extended features such as dependency injection, routing, animations, view encapsulation, and more are available.
•It is supported by Google and a great development community.
•Angular is a comprehensive solution for rapid front-end development. It does not need any other plugins or frameworks.
•Angular is unit testing ready, and that is one of its most compelling advantages.
Node.js
•As discussed earlier, Node.js is what permits the net developer to use JavaScript on the back-end of the web site. It is an event-driven runtime surrounding that contain infinite quality, Independent packages get downloadable via npm. In fact, Express.js is one in all the foremost standard packages in npm. Different standard packages will include Passport for user authentication, still as body-parser for managing kind input.
•Instead of learning a new language and adjusting to new syntax rules, using Node.js permits you to become an excellent expert in a single programming language. If you are unfamiliar with back-end development, you will have efficient time for picking up the fundamentals. Eventually, you’ll boast a high level of information and the subtle details of JavaScript because your entire software stack relies on it.
Benefits of the MEAN Stack
There are some additional benefits of Mean Stack
The MEAN Stack Is Intuitive
The MEAN stacks provide everything necessary to form a competitive net application, nonetheless, It is easier compared to the LAMP stack. though it’s doable to have confidence in strict schemas and format information specifically, as needed within the LAMP stack’s MySQL, it is not necessary within the MEAN stack. In fact, MongoDB permits the developer to simply add new information to some extend, however not all, of the things in a very JSON file. This can be in contrast to MySQL, wherever a developer merely should offer information to each item, even if their value is either “undefined”, or absent.
The LAMP Stack Is Outdated
Another common criticism of the LAMP stack is that it is taken by some. PHP has fallen beneath significant criticism for its excessively advanced practices and lack of trade specialists. In contrast, the MEAN stack has become one among the trade normal stacks for tiny startups, fast development, and productive, profitable companies. As a developer, you may possibly face all types of clients, together with some rely on older technology. Though PHP could also be employed in some cases, operating with the MEAN stack is ultimately a more robust selection for any developer.
MEAN Stack Applications
MEAN might not be good for all the applications in some kind of aspects, there are some specific applications wherever it is getting used. The cloud-native applications build it a robust selection because of its flexibility, scalability, and its ability to manage coeval users. The innovative applications by using MEAN were included below.
- Tracking location and Mapping
- Calendars
- News aggregation sites and
- Expense tracking
