What is the MEAN stack?
What makes the MEAN stack?
The MEAN stack consists of four different technologies.
M – MongoDB
MongoDB is a document-oriented NoSQL database. It is used for high-volume data storage. It doesn’t use tables and rows like the traditional relational databases. Instead, it utilizes collections and documents to store data in binary JSON format.
MongoDB offers powerful ways, including ad hoc queries, indexing, and real-time aggregation, to easily access and analyze data efficiently. The document model maps to the objects in your application code so you can easily work with data.
MongoDB is a distributed database at its core. It supports horizontal scaling and high availability. Also, the document database is an open-source solution so you don’t have to spend a single penny to use it with your application.
E - Express.js
Express.js is an unopinionated and minimalist web framework. It provides a robust set of features for building single-page, multi-page, and hybrid web applications quickly. Express.js offers a myriad of HTTP utility methods and middleware. By utilizing them, full-stack developers can effortlessly create a robust API for their web applications.
Express.js facilitates non-blocking I/O operations. As a result, it is lightning fast at executing code. Also, Express.js is a lightweight framework, so you can leverage it to build large-scale applications conveniently.
Expess.js has an unopinionated structure. It makes the framework suitable for combining with a microservice architecture, so you can easily achieve higher scalability and improve the performance of your web application significantly.
A – Angular
Angular comes with a huge collection of libraries. By using them, you can build web applications quickly. It supports directives, which allows full-stack developers to extend the functionality of HTML components easily. You can use them to form custom HTML tags and components. Also, they can help you to manipulate the behavior and data of Document Object Model (DOM) trees.
The Angular framework employs MVC architecture. It facilitates organized and clean coding, which can save you a lot of time. Angular provides cross-platform support. So, you can use it to build progressive web apps, mobile apps, and desktop applications for Mac, Windows, and Linux operating systems. Overall, it is a complete frontend development framework.
How can I install Angular Command Line Interface?
Angular Command Line Interface (CLI) helps you to create Angular projects effortlessly. To install it, you have to open a terminal window and run this command:
npm install -g @angular/cli
Now, to check whether it’s installed correctly, simply run this command:
If everything is OK, you will see this output:
N – Node.js
Node.js is lightweight and efficient. It uses an event-driven, non-blocking I/O model for executing code quickly. As a result, it has become a perfect choice for making real-time web applications that run across distributed devices.
Node.js offers high scalability and a huge collection of open-source packages. By utilizing them, you can add new features to your web applications effortlessly. Being single-threaded, it can handle a large number of simultaneous connections efficiently.
MEAN Stack vs MERN Stack: Which one should you choose?
Both of the stacks are very powerful. However, which framework should you choose to build your next web app?
Managing and Updating Web Applications
With the MEAN stack, you can manage and update your applications easily. As explained earlier, Angular supports the MVC architecture, which facilitates organized and clean coding. As a MEAN stack developer, you will find it very easy to transfer code from one framework to another. The technology stack utilizes an intermediate layer to separate the database code from UI code, so you can manage and update your web app conveniently.
However, as a full-stack developer, you will not get the same convenience while using the MERN stack. Managing the React code requires more effort and involvement due to the third-party libraries. You cannot update it as easily as the Angular app.
So, if you want to manage and update your web application conveniently, the MEAN stack is the right tech stack for you.
Third-Party Extension Configuration
If you are working on enterprise-level apps, the extensions can make your life a lot easier. They help you to add complex features easily and quickly. Both of the technology stacks support a wide range of extensions. But as a full-stack developer, which is the better choice for you in terms of configuration?
As a MEAN stack developer, you can handle the third-party extensions easily with plug-and-play configuration. There is no extra hassle. On the other hand, the process is a bit complex for the MERN stack. You need to perform additional configurations for using the extensions.
If you want to avoid the hassle of performing extra configurations, the MEAN stack is the right stack for you.
There is no apparent difference in the learning curve of MEAN and MERN technology stacks. The documentations of Node.js, MongoDB, and Express.js are very easy to follow.
However, when it comes to Angular and React, the learning curve will change. The Angular framework utilizes templates and TypeScript. It starts from primary elements such as directives, modules, components, services, dependency injections, and more. So, as a MEAN stack developer, you will find the learning curve to be a bit steeper. On the other hand, the React framework is much easier to learn. It allows you to break down the interface into several simple components. So, you can grasp everything conveniently. Also, it has easy-to-follow documentation to help you get started quickly.
If you want to avoid a steeper learning curve, the MERN stack is the right choice for you. However, if you love to learn deeply and solve tough problems in large-scale apps, it is worth giving the MEAN stack a try.
MEAN Stack Case Study: Does it really benefit software development teams and companies?
MEAN stack has been used by big names in the tech industry, including Netflix, LinkedIn, and PayPal. But does it really benefit the software development teams? Let’s find it out.
The number of users began to increase dramatically due to the improved user experience. Netflix now has roughly 222 million subscribers, which makes it the largest streaming service on the planet.
Due to the PayPal system's enhanced performance and safe transactions, more people began to prefer PayPal over other online payment solutions. Right now, the company has around 325 million active account holders.
Wrapping Up: Should a full-stack developer use MEAN stack for building dynamic web apps?
The MEAN stack technology helps you to build dynamic applications quickly. It is highly extensible and maintainable. It enables you to boost performance significantly and its layers are composed of open-source technologies.
MEAN stack developers can save a lot of time because the framework enhances web development workflow. If you are on the fence about what technology stack to work with, consider using the MEAN stack for building dynamic web applications.
