The creation of web applications has never been easy, especially when choosing the best frameworks. Developers and companies are constantly searching to find software, technology, or tool that helps streamline the company’s goals and requirements. As a result, developers have utilized their skills and experiences and built apps using integrated stacks. Here comes the part of mean development where agencies use it as a standard building block. They spend much of their time on apps that differentiate between businesses instead of connecting various elements together for the proper functioning of web devices.
We have previously seen companies taking help from advanced technologies, integrating them into the business models to gain from economies of scale. As a result, mobile or web app development is done around new-age technologies. These technologies include AI, AR, IoT, Blockchain, etc. However, talking about web apps, developers use full-stack or MEAN stack instead of using other tools. Many of you may be familiar with MEAN, MEVN, and MERN stacks that have taken the development industry by storm. The developers who have the knowledge and expertise in these are considered more than those with no skills.
What is MEAN Stack Development?
The term ‘MEAN Stack’ has become common in the software or development industry where companies try to build web apps. Talking about MEAN specifically, it is a JavaScript framework made from a combination of four different advanced technologies that become the stack layers when put together. Each alphabet stands for a different technology that we will be seeing shortly and has a specific purpose. However, all of them work in the direction of running smooth web apps for businesses or clients. The better the web app, the better will the ROI. Here are the following technologies:
- ‘M’ stands for MongoDB, a NoSQL document database system.
- ‘E’ stands for Express.js, a web framework to build web apps in Node.js.
- ‘A’ stands for Angular.js, a client-side JavaScript framework by Google.
- ‘N’ stands for Node.js, a server-side JavaScript web server.
A MEAN developer is only hired to build JavaScript web apps. He only has knowledge about this particular platform and works mainly on the MEAN stack. Moreover, they know how to work smoothly for both front and back-end apps.
The process starts when the client makes a request, and Angular.js accepts the request. The information is passed to Node.js, where all the client and server requests get handled easily. After this, the information moves to Express.js, where it calls MongoDB to set the database, and a response is returned. MongoDB retrieves the information or data and returns the request to Express.js. Once done, Node.js further returns the request to clients. Lastly, Angular.js displays the request.
The 4 Technologies
Now that we have understood what a MEAN stack is with its technologies, we should dive deeper into them to better understand and apply them when developing highly-responsive applications.
MongoDB:
The often asked question about MongoDB is its intricacies and the will to know what it actually does. This open-source, cross-platform database system is written in C++ to store data using binary data types in the key-value pair like JSON. It is often referred to as a document-oriented or NoSQL Database. Besides this, any document here looks similar to an Object in OOPS. Hence, it is the best choice for any database system where a company needs to manage big data easily.
Further:
Developers or companies do not need to keep updating the complete table. One can create a complete app with JavaScript. It is the first tier in the web app process.
Express.js:
The next in line is Express.js, a lightweight and flexible framework designed to build single, multi-page, or hybrid web apps. Moreover, it uses the Pug engine to support various templates. It is known as a de-facto framework or platform for Node.js too. It has robust models for URL routing and managing HTTP requests or responses. All the functions in the end-use MongoDB’s Node.js drivers through callbacks or Promises to access or update data in the database. It is known as the second tier of web app development.
Angular.js:
The third technology is Angular.js, an open-source JavaScript framework maintained by Google. It aims to introduce the MVC architecture in the browser-based app that enables efficient development and testing mechanism for web developers. Further, it supports customization that leads to more innovative web applications. It leverages developers to use HTML as a template language, extending the HTML syntax to create a dynamic web experience.
Node.js:
The last one, Node.js, leads to web service creation and the development of web apps. It is a server-side JavaScript web server that uses a non-blocking and event-driven I/O model. Since it is a lightweight technology, it easily supports data-intensive apps which smoothly run on distributed devices. Now, users can run it on Linux, MS Windows, and OS X in real-time.
Advantages of MEAN Stack
Web apps are made with the help of the MEAN stack. They are real-time, advanced apps running natively on the cloud. Depending on the client’s demand, you can even find such apps in different formats like single-page or multi-page apps. There are various advantages of creating a web application with the help of MEAN developers. Still, few include advanced workflow management tools, interactive forums, influential aggregation sites, and calendar apps. These advantages are an outcome of JavaScript, the framework that makes the integration of all technologies or components a success. Unlike other frameworks, its supports front-end and back-end development, cutting down the cost of hiring different developers to build the web app or use various tools that might increase the price. Thus, making the process faster.
Conclusion
Web applications have increased in demand in the past few decades, helping companies create an online presence in today’s world. At a time like this, when the demand is sky-rocketing and businesses are flourishing, the role of the MEAN stack comes in between the development. Companies hire a MEAN stack developer who has the knowledge and experience of building front-end and back-end with advanced tools. So instead of hiring different developers to create web apps, a single specialist takes over the task and completes it in due time with a highly-responsive and functional web app.
