MEAN stack is currently one of the hottest trends in the website and web application development . It is hard to find an experienced web application developer who does not know what is MEAN stack. Like other software stacks, MEAN stack also provides a set of components to simplify and accelerate custom web application development. The four core components of MEAN stack forms a platform that enables programmers to build custom web applications without requiring additional software development tools.
MongoDB: The open source and cross-platform non-relational/NoSQL database features a documents oriented data model. Unlike relational databases, MongoDB does not store data in rows and columns. Instead, it splits the data across multiple servers. Hence, it becomes easier for web developers to speed up data access, work with large volumes of data, and keep both business and user data secured.
Express.js: The fast and minimalist web framework is developed based on NodeJS. The developers can accelerate development of web applications and APIs by using Express.js as a robust server-framework for NodeJS. They even have the option to extend Expres.js by using a variety of plugins. Like MongoDB, Expres.js is a backend component of MEAN stack.
AngularJS: The frontend web application framework accelerates web application development by allowing programmers to extend HTML syntaxes. AngularJS enables developers to express various components of the web application by extending existing HTML syntaxes. It even simplifies development of large and complex websites by supporting model-view-controller (MVC) architectural pattern.
Take Advantage of MVC Architectural Pattern: As noted earlier, AngularJS supports MVC architectural pattern. Hence, MEAN stack enables programmers to simplify development and maintenance of complex web applications. The developers can leverage MVC architectural pattern to keep the application’s user interface layer separated from the business logic layer. Also, the two-way data binding facilitated by AngularJS synchronize the data between model and view components automatically. The developers can further boost the performance of the web applications by implementing a variety of caching techniques.
Deploy Web Applications in Multiple Ways: MEAN stack allows developers to deploy web applications on conventional web servers and in the cloud. Major cloud service platforms support both NodeJS and MongoDB. Unlike relational databases, MongoDB works seamlessly on popular cloud service platforms. The developers can further set up, scale, and manage databases in the cloud efficiently by taking advantage of MongoDB Atlas. At the same time, they also have the option to deploy the web applications on various web servers.
Work with Third-Party APIs: Most developers nowadays avail third-party APIs to make web application exchange requests and responses rapidly. The APIs store and exchange data efficiently by leveraging JSON syntax. MEAN stack makes it easier for programmers to work with third-party APIs by supporting JSON format. The core components of MEAN stack support JSON format fully. Hence, the developers can store all data in JSON format. They can further leverage the JSON format to speed up web development by availing an array of third-party APIs.
Boost the Website’s User Experience: The loading speed of a website nowadays directly impacts its user experience and search engine visibility. Hence, the developers have to explore ways to prevent user abandonment by making the website load faster. MEAN stack helps developers to boost the performance and speed of websites by leveraging NodeJS. A number of studies suggest that NodeJS is much faster than many widely used server-side programming languages. NodeJS features a non-blocking I/O model that distributes the incoming connections and allocate heaps to each connection. Hence, the web application loads faster and handle a sudden surge in user load.
Curtail Custom Web Application Development Cost: Both large and small enterprises nowadays opt for open source web technologies to curtail project overheads. Each of the four core components of MEAN stack is open source and free. Hence, the developers can build web applications with MEAN stack without paying any licensing fees. Also, the core components of MEAN stack provide developers with a robust web development platform. The developers can leverage the platform to build web applications without using comma ercial web frameworks and development tools.
Each Component of MEAN Stack has Its Own Shortcomings: The four components of MEAN stack simplify web application development by forming a robust platform. But each component of MEAN stack has its own pros and cons. For instance, the developers must be familiar with several complex concepts to leverage NodeJS’s scalability. Likewise, AngularJS often makes the web applications complex and Express.js is considered as a monolithic web framework. Also, many developers consider relational databases to be more stable and reliable than MongoDB.
