This architecture is highly efficient, and increased functionality can be achieved with minimal lines of code. Also, the MEAN stack provides the much-required scalability and speed when creating an MVP, which is one of the main reasons for its increasing adoption among startups. Finally, its relatively small learning curve is an added bonus.
What Is the MEAN Stack?
These technologies work synergistically to deliver regular website pages, innovative IOT solutions, and facets in between. For developers, it is likely that the key attraction is using a single language for both frontend and backend development.
Technologies Composing the MEAN Stack
1. M – MongoDB:
MongoDB is a schema-less NoSQL database that is used for application data-storage in the MEAN stack. Unlike typical relational databases, it does not require a schema design before creating the database.
Instead of tables, MongoDB is document-oriented and uses ‘Binary JSON’ to store data, offering greater flexibility. Further, fields can be modified in the document, and the data structure can be changed, as well. One of the most essential benefits is horizontal scaling and high availability.
2. E – Express.js:
Express.js is a minimalist, back-end framework for Node.js that is well-accepted because it simplifies routing, supports the Connect module, and offers useful features and extensions. Also, Express.js accomplishes these tasks without overriding Node.js features that are popular amongst developers.
Further, it enables faster web application development and allows developers to code smartly through code reuse with the help of its built-in router. Getting the server up and running becomes a breeze with Express.js, which might be why Express.js has the largest community in comparison to other frameworks available for Node.js.
In the MEAN stack, Express.js takes care of the backend by managing the two-way data transfers between the front end and the database. It ensures that data reaches the end-users quickly, without glitching. Despite its minimalism, Express.js manages efficient handling of all backend events.
3. A – Angular.js:
From handling initial wireframes to animations and transitions for complex websites and applications, Angular.js is packed with features suitable for different scenarios. Using Angular.js, developers can take advantage of features like two-way data binding, modularizations, RESTful API handling, and AJAX handling.
Other features like filters allow data manipulations at the view level without having to implement any changes in the controller. In short, it’s perfect for writing less code that would be redundant without Angular.js.
4. N – Node.js:
Node.js allows two-way connections, meaning that both server and the client can initiate communication; unlike the past where only the client could initiate the data exchange. It also allows simultaneous connections which result in fast, scalable applications.
In the MEAN stack, Node.js is essentially a backbone that connects all the other technologies. For example, Express.js is a framework specific to Node.js, and deploying MongoDB with the built-in Node.js server simplifies many facets.
Further, Angular.js also works well with Node.js to allow fast data transfers. However, Node.js is mostly geared towards handling multiple low-resource requests simultaneously rather than high-resource requests.
The Popularity of MEAN Stack Technologies
The technologies that form the MEAN stack are approved by several high-profile companies. Just to give you an idea of its immense popularity, giants like Linkedin, PayPal, Trello, Uber, and NASA are using Node.js for their main applications.
Advantages of MEAN Stack Development
Here are some of the pros that contribute towards the increasing acceptance of MEAN stack development:
1. Isomorphic Code:
MEAN stack development facilitates isomorphic coding, which is code that can run on the server and the client side. Code that can be rendered on the browser as well as Node.js effectively solves the problem of search engine indexing since search engines crawlers do not support client-side rendering.
2. Open Source Components:
All components of the MEAN stack are open source, which has several benefits. Opens source facilitates a shared community approach to development.
Specifically, the open source community is often dedicated to updating and improving the code, adding new features, and fixing existing bugs. This ensures that the MEAN stack components are always up-to-date. MEAN stack developers get to enjoy being on the cutting-edge of technologies and customizability of the open source code to suit their unique requirements better.
3. Schema-less NoSQL Database:
The MEAN stack uses MongoDB for storing data, which is a NoSQL database. NoSQL effectively overcomes the limitations of relational databases. It allows for greater flexibility and seamless data model changes.
MongoDB is the obvious choice for handling large volumes of structured, unstructured, and semi-structured data. In the absence of a pre-designed schema, any change in the data model can be introduced in the same document collection without having to disturb older data. This flexible JSON document structure is critical for large applications dealing with Big Data and frequent code changes.
4. MVC Architecture:
Angular.js supports MVC architecture, allowing for the separation of application logic from the user interface. This facilitates rapid development since multiple developers can work on different parts of the code simultaneously.
Separation of concerns also means a better overall end-user experience. MVC is excellent for developing large-sized applications because it offers multiple views, asynchronous programming, and data returns without formatting.
6. Cost-Effectiveness and Cloud Compatibility:
MongoDB makes use of the cloud for application functionality, resulting in a low disc space requirement. Deployment cost is also low for MEAN stack applications since the open source technologies are free, and the application can run on a Linux server.
7. High Speed and Cloud Compatibility:
8. A Helpful, Resourceful Community:
Last but not least, the open source community for all the technologies composing the MEAN stack is impressive. Since tech giants and other high-profile companies are already working with the MEAN stack, the community is resourceful and supportive.
Drawbacks of MEAN Stack Development
The MEAN stack does have some drawbacks of its own. For example, MongoDB is not as stable and reliable as the traditional, relational databases. Similarly, Angular.js can be a little tricky and complicated for more straightforward web applications.
Angular.js also does not support older Safari, Internet Explorer, and Firefox versions. Besides, it isn’t the best option for SEO; although, this is a problem well taken care of by Node.js.
The above discussion indicates that the MEAN stack is continually evolving, improving, and will remain everlasting. It’s well-adopted by tech-giants like Google and Amazon but is also equally popular among start-ups.
Developing innovative websites and web applications are simplified using the MEAN stack because of how the comprising technologies work with each other. Partnering with someone with skills, expertise, and experience in developing MEAN stack applications is the key to making the best out of these technologies.
