When it comes to tech stack, there are a plethora of options for you to choose from. Here, I will help you overcome the challenge of comparing MERN Stack VS Mean Stack VS Full Stack so you can decide the best technology for your project!

What is a Tech Stack?

A stack is a collection of technologies, tools, and programming languages. Typically, it is of two kinds:

App stacks Collection of databases, emails, word processing, etc.
Technology stacks If you ask what does stack mean in technology, I would refer to it as a collection of tech services that you need to develop and operate any project. For example, web frameworks, tools, and programming languages. You can also consider marketing tools, sales tools, or ERP & CRM tools in a technology stack.

However, this blog exclusively deals with the technology stack in the development context. Here, we will dig deeper into Mean stack, Mern stack, and full stack development and their benefits and drawbacks.

What is a Mean Stack?

It is a Javascript-based tech stack used for developing websites and web applications. It consists of the following technologies:

Mongo DB: A document database
Express.js: Backend web framework used with Node.js
Angular.js: Client side or frontend development framework
Node.js: Javascript web server

Mean Stack Development Process

Frontend

You have Angular at the top for developing an interactive frontend interface. With Angular.js, you can create intuitive experiences for your end users much more conveniently than you can by using HTML or JS alone. Right from communication and localization to form validation, you can develop more converting interactions here.

Backend

In this tier, Express.js runs on the Javascript server of Node.js. Apt for URL routing, HTTP requests/ response handling, and XML HTTP requests, it handles all the tasks of server-side development.

Database

To store data for your application, you need a database that is easy to work with other technologies of the Mean tech stack. That’s where Mongo DB comes into the picture with features like cross-cloud scalability and complete security.

Advantages of Mean Stack Development

Fast development speed: Often used for developing MVP because of its quick development pace.
Versatile development: Coding using Mean stack technology is a lot simpler and can be transitioned seamlessly between the client and server sides.
Encoding: Also known as Isomorphic coding, you can write code once and use it for multiple platforms. Thus, you can save on development time and cost.
Large community: It is open-source and is supported by a huge community of Mean stack developers.

Disadvantages of Mean Stack Development

Since Javascript wasn’t originally built for backend development, there are chances that your application might face performance issues. The fast pace development of Mean stack technologies may also lead to poor development practices, causing problems. However, with appropriate AngularJS performance optimization, you should be able to overcome these situations.

What is Mern Stack?

It is said to be a replacement of the Mean stack where Angular is replaced by React.js. It consists of the following technologies:

Mongo DB: An open-source document database
Express.js: Backend web framework used with Node.js
React.js: Frontend Javascript library apt for developing intuitive user interfaces
Node.js: Javascript web server

Mern stack development has gained popularity in quite a short time, especially because of the hugely popular library React. It has become the second most popular web framework of 2022, as per Statista report.

The same report shows Angular.js to be in the 5th position which is used for developing Mean apps. It is to note that the support for Angular.js has been discontinued, however, it is still popularly used by Mern stack developers because of its large developer community.

Subsequently, if you compare Mern stack vs Mean stack, you will see that React holds better compared to Angular as far as UI layer abstraction is concerned.

Mern Stack Development Process

Frontend

React library is used for developing an interactive web or frontend interface. With React.js, you can create stateful and data-driven UIs with minimal coding. It is great for creating complex user interfaces, error handling, and managing forms and lists, all using simple components.

Backend

In this tier, Express.js runs on the Javascript server of Node.js. Apt for URL routing, HTTP requests/ response handling, and XML HTTP requests, it handles all the tasks of server-side development.

Database

To store data for your Mern apps, you need a database that is easy to work with other technologies of the stack. That’s where Mongo DB comes into the picture. With its features like cross-cloud scalability and complete security, it is the perfect solution to send, store, or retrieve data.

Advantages of Mern Stack Development

From the backend or server side to the frontend/ client side, the entire development cycle is covered with Mern web development.
With robust GUI and command line tools, the Mern tech stack offers a flexible data model for developing web apps.
Since it involves client-side development alongside server-side, it compares with full stack development.
It’s open-source and anyone can use the technology for developing web apps without having to pay any license fee.
There’s also a plethora of testing tools like built-in React testing library, React hooks testing library, Enzyme, Jest, etc. available that work well with Mern stack technologies.

Disadvantages of Mern Stack Development

The use of third-party libraries is extensive in Mern stack development as React itself is a library and has to depend on other libraries for many functions.
It is most appropriate for single-page applications and not large projects.
If you compare Mean stack vs Mern stack, the former is better in terms of error handling with its Typescript feature for error prevention. However, no such option is available for Mern stack technologies.

What is Full Stack Development?

Full Stack Development Technologies

It refers to both types of development: Client side as well as server side. If you hire a full-stack developer, they will be proficient in multiple full stack languages and best web frameworks that can help you develop the front end and backend seamlessly.

It consists of the following technologies:

Frontend: HTML5, CSS, JS, Ajax, React, Angular, TypeScript, and others.
Backend: PHP, Python, Django, Nodejs, GO, Expressjs, Middleware, Caching, etc.
Database: MySQL, SQLite, Postgres, Clusters, MongoDB, etc.

Advantages of Full Stack Development

Switching swiftly between frontend and backend as per your need is easy with full stack development.
Minimized development cost.
The entire frontend design and development part is handled by one team. Thus, they are more in control of the project and can meet your expectations appropriately.

Disadvantages of Full Stack Development

A full stack developer might find it overwhelming to keep up with the new trends and technologies as the number of frontend, backend, and other cutting-edge technologies are growing significantly.
Working with too many technologies can get confusing for developers, thereby slowing their development speed.
