MEAN Stack Architecture Explanation
1. When any client makes any request, it is firstly processed by the AngularJS. AngularJS is a client-side language in JavaScript.
2. After that, the Request enters in phase 2 which is NodeJS. NodeJS is a server-side language in JavaScript.
3. After that Request enters in phase 3 which is ExpressJS it makes the request to the database.
4. After that MongoDB redeem the data and return the response to the ExpressJs.
5. Then ExpressJs return response to the NodeJS and then NodeJS return it to the AngularJS to display the result.
Mean stack is combination of technologies which are the collection of JavaScript used to develop web applications. Mean Stack is given us a modern approach to web development which runs on every tier of your application. Mean is a combination of a group of the technologies that synergize well together. The Node.js saves us from learning a separate language as it allows us to use JavaScript on the frontend as well as the backend. In a mean stack with NoSQL, nature of MongoDB you can build a product with clear attributes, and without worrying about migrations you can change and alter the data layers.
Mean is a simple rearrangement of initial letters of a group of technology. Upgrading the technology and switch the bottom platform from an OS (Linux) to JavaScript runtime has helped accomplished OS independence. AngularJS runs on smartphones, tablets, laptops, desktop and even smart TVs; thus, it's not only focused towards mobiles and doesn't treat mobile devices as an inferior national. The MEAN stack is essentially a group of languages and technologies accustomed to develop sites or applications by the developers. You can simply write comprehensive test suites for your Mean app with best texting frameworks like JasmineJS, KarmaJS, and MochaJS. Mean is an application that fully written on JavaScript technologies.
Introduction to Means (MongoDB, Express.js, AngularJS, Node.js):
MongoDB
It makes it easier to pass. data between consumer and server by saving information in binary JSON format. The idea that it works is assortment and documentation. MongoDB provides high performance, high convenience, and straightforward measurability because it's a cross-platform, document-oriented database. To adopt JSON-like documents which have BSON (dynamic schemes) MongoDB shuns the relational database’s table-based structure, which makes data integration for certain types of applications faster and easier.
EXPRESS.JS
It provides options for single and multi-page web applications and is inspired by the popular Ruby framework, Sinatra. It provides a strong set of options for internet and mobile applications; it's a negligible and versatile Node.js web application framework. Express.js allowed developers to create software package with JavaScript on the server side for the primary time by giving JavaScript new back-end practicality.
ANGULARJS
AngularsJS helps in eliminating many the unwanted code unless we'd have written with its feature of data merging and dependency injection. To express your application’s components clearly can use HTML as your template language and extend HTML syntax. It is additionally a structural framework for dynamic net apps. It provides features like two-way data binding.
NODE.JS
Node.JS is light-weight and economical because it uses an event-driven, on-blocking I/O model. Chrome V8 JavaScript engine is used to build JavaScript runtime. It has the most important ecosystem of open-source libraries within the world called npm. It may also run JavaScript applications outside the browser. It is a cross-platform runtime environment. It is free to use his open source.
APPLICATIONS OF MEAN STACK DEVELOPMENT:
• Mean stack gets updated often because it has open source components.
• It is easy to develop web applications using Node.js because it provides a good variety of JavaScript modules from its humongous library.
• Mean stack allows the developers to write code in only one language which is JavaScript for both client and server side which makes it a simple and fast language.
• The data flows precisely among the layers of JSON and does not require rewriting or reformatting because Mean uses common JSON format of data everywhere.
• Mean stack has become a leading end technology because transferring of code from a particular framework to another framework is easy from Mean.
• Mean is highly flexible. You can easily test your application on the cloud platform after the successful completion of its development process, and even add extra information by just adding an extra field to your form.
• Development of apps using mean stack is less costly because it just requires developers who are proficient at JavaScript.
• Mean helps in the current period to develop real-time demonstration applications which are trending. There is no need to perpetually update websites for every server request as a result of it utilizes single-page applications (SPAs).
• Developing applications using Mean saves your lot of time and this it does because it has an infinite set of module libraries for Node.js that are ready for use and you don’t need to waste some time in making modules from scratch.
• It not only saves some time but additionally creates quality best applications.
• MVC (Model View Controller) architecture is also supported by Mean.
• Mean Stack application is very flexible to understand which helps the developers to customize it as per their needs.
• Front-end development: in front-end developing the developers makes the website interactive by working on its appearances. Mean stack provides us with this feature.
• Back-end development: in the back-end development the developers make the website more functional by adding new features, making it faster etc. this feature is also provided to us by the mean stack.
Conclusion
Mean stack technology is rising day by day and is additionally simple to use. The leading mobile app development firms use Mean Stack for developing prime mobile apps as Mean Stack is listed because of the best technology for developing mobile apps. For most innovative and cut-edged web applications this is the foremost appropriate technology.
