What is MEAN Stack? MEAN Stack Components and Benefits


The MEAN stack is used to make web apps

A “tech stack” is a group of programming languages and other software tools used to make creating software faster. Because the IT ecosystem has been working on many different applications for so long, they know which technologies work best together to make things go quickly. It’s called the MEAN stack, and it’s one of the things web developers love to use. For your job, MEAN Stack Training in Delhi is a good choice because it will help you grow.

MongoDB, Express.js, Angularjs (or Angular), and Node.js are some of the most popular web application development tools and technologies. The MEAN stack is an acronym for this technology stack.

The components of the MEAN stack and how they help web application development:

Let’s look more closely at the parts of the MEAN stack and see what they can do for us.

For a database, MongoDB is the best choice.

It is a significant advantage of the MEAN stack that it comes with the most dynamic NoSQL database in the form of MongoDB.

It’s better than MySQL.

The first choice for most developers is MySQL. Here’s why MEAN developers prefer to use MongoDB instead:

MongoDB can be more flexible when it comes to making a schema.

MySQL would not let you make any changes unless you changed the design of your schema first. Slows down the development and deployment process a lot. It also limits your options regarding how quickly you can change things.

Thus, MongoDB has a lot more flexibility in making a schema. It doesn’t matter if you drop a few documents into MongoDB that don’t have any connection to each other. It still works. Because non-relational databases don’t have to be linked to each other, they can be mighty.

  1. Allows for more speed and better performance.

Small, structured data sets are suitable for MySQL because they are easy to work with and aren’t too big. It would be like putting out a fire with a garden hose if you had a lot of unstructured data. Too little, too late. This isn’t enough.

The magic of MongoDB is that it can handle massive, unstructured data sets at lightning-fast speeds, which is why it is so great. MongoDB is an integral part of the MEAN stack, and its benefits for an efficient database can’t be matched.

  1. Express.js is suitable for making Javascript apps.

People who make web apps do most of their work in the backend. If you have a complicated backend, your application will be just as complicated as it is now. The main thing about the MEAN stack is how Express.js is used to run the backend.

Express.js is a Node.js framework that is both flexible and efficient. Express.js is what you need if you want a good mix of ease of use and many features.

Express.js makes sure that data is sent smoothly to the end-user by taking care of the interactions between the frontend and the database.

This is a list of Express.js’s main features and benefits of Express.js for making web apps.

  • It is a simple framework that doesn’t take up a lot of space in your application.
  • Express.js is an excellent error handler that gives you simple templates to speed your development.
  • Commons in Express.js save time by ensuring that you don’t have to change a variable in a shared namespace.

There are many ways you can quickly grow your application, such as by adding more nodes and resources as you need.

  • Express.js runs on Google’s V8 engine, making it run faster and without any lags or errors.
  • Express.js has a feature called caching. Thus, you don’t have to re-run the codes often, which means your web pages load faster.
  1. In addition, AngularJS is used to build the site’s front end.

When AngularJS came out in 2010, it was the first time it was used. Since then, it has been one of the most popular JavaScript frameworks for front-end JavaScript apps and web pages. Angular 2+ (also known as Angular) has become many people’s favorite after it was made better.

So, what can Angular do for you as a frontend tool? Let’s see how Angular fits into the MEAN stack and what it can do for us:

  • Angular has a modular structure that makes it easy to break down the whole application into separate features. Thus, you can quickly find the parts of code that can be reused and save a lot of time.
  • Angular lets you load things slowly. This allows the browser to show the data users have asked for right away without downloading all of the data first.

There are a lot of components in Angular, so new developers don’t have a hard time understanding how the application code works.

  • The command-line interface (CLI) of Angular makes it easier to create apps and improves the code.

When you use the dependency injection function in Angular, you can make your application run faster and make it easier to make changes.

This is because the Ivy renderer reduces the size of the bundle, which makes excellent apps lighter.

  • Typescript makes it easier for the developers to find and fix mistakes as they work.
  • When you use the declarative view function, you can save time because it loads the components automatically based on the layout you choose.
  1. Node.js for developing the backend of your site:

MEAN stack components and their benefits are ideal for cloud-based applications that need to increase. Because it has the Node.js framework as its backend framework.

Node.js is a JavaScript framework that is free and open source. It uses asynchronous events to process multiple connections at the same time. This feature of Node.js helps the framework use a single-thread architecture, making it easier for users to have a smooth experience across many connections.

This isn’t the only thing that Node.js can do for you.

This drastically cuts down the time-to-market cycle.

  • With Node.js, you get real-time feedback from the production environment, making it easy to deploy your apps.
  • Node.js is better at scaling.
  • It eliminates the need to switch back and forth between the backend and frontend.
  • Node.js is a well-tested and mature tool with much help from other developers.
  • Node.js makes it easy and quick to make MVPs.
  • It doesn’t have a steep learning curve, so anyone who knows JavaScript and object-oriented programming basics can learn and use Node.js, too.

If you want to learn more about the MEAN Stack, then MEAN Stack Training in Delhi is a good choice.


MEAN Stack Training in Delhi has become very popular in the last few years. Like any other tech stack, MEAN isn’t the best choice for every app. However, because Angular is used, it’s great for making apps for businesses and single-page apps. Another thing that makes it a good choice for cloud-based apps is the ability to switch between client and server-side codes.
