MEAN vs MERN: A Comprehensive Guide to Selecting the Right Tech Stack

When it comes to web development, the decision of which technologies to use basically defines the success of an application in terms of stability, modifiability and performance. There are mainly two commonly used full-stack JavaScript frameworks namely the MEAN stack and the MERN stack. Both of them use MongoDB, express-js and Node-js, and differ in front-end framework; MEAN uses Angular while MERN uses React.

In this resource, you will find out what is the difference between two types of stacks, which types of businesses they are fit for, and selecting the right stack for your project in MEAN vs MERN.

MEAN Stack – An Overview

As the progress in the web development field never seems to slow down it is essential to determine the appropriate tech stack for further more stable and effective application creation. Currently there is a full-Overflow Technology Solutions: Programming Overflow has four components namely MongoDB, Express.js, Angular, And, Node.js- stack name MEAN. Included in this stack is both the front end framework and the back end framework with the single language being JavaScript, thus allowing for enhanced development.

Components of MEAN Stack

It will be easier to understand what the MEAN stack is by analyzing its key components which are four as follows;

1. MongoDB: Specifically, MongoDB is a type of database system that it uses the JSON structure and which is a NoSQL document-based database that offers flexibility and the ability to grow and add more space as needed.

2. Express.js: A small library for creating API and web applications for Node.js easily and quickly.

3. Angular: It is a unique platform that has been developed by Google and its function is to assist in creating vivid and interactive front-end solutions.

4. Node.js: Node is a framework that allows running the JavaScript language on the server side while maintaining efficient coupling with the client side.

Advantages of Using MEAN

1. Complete JavaScript stack: Developed solely in one language for front end as well as for back end systems.

2. High scalability and real-time web functionality: This is a suitable tech stack for your project for those applications that require data to be updated in real-time within constructing complexes.

3. MongoDB's flexibility: It easily deals with large data storage and analysis to increase the efficiency of the algorithms.

4. Fast development time: It also makes the development and debugging process faster because the full stack is written in JavaScript.

Disadvantages of Using MEAN

1. Not ideal for small projects: It is also important to note that the use of MEAN stack could be over complicated for most ordinary websites.

2. Requires skilled developers: It suggested that candidates must know multiple frameworks and databases are required as they are mandatory.

3. NoSQL limitations: Some cases can be poorly solved with MongoDB, for example, applications working with complex relational data.

4. Performance concerns: In certain places, it may face problems with performance as compared to other types of tech stacks depending on the application type.

Real-World Examples of MEAN

The MEAN stack is widely implemented by the large companies across the world for securing incredible and reliable applications. Below are some of the readily recognizable platforms which incorporate MEAN:

• LinkedIn: An application in the field of professional networking that is based on MEAN and can effectively apply this advantage.

• PayPal: An e-Commerce that involves a payment process that is safe and real-time.

• Intel: It uses MEAN for handling a large amount of data and for processing the same.

• Accenture: A multi specialized international consultancy company using MEAN for enterprise level application.

• The Weather Channel: The weather data is real-time and the application is developed with MEAN.

MERN Stack – An Overview

The MERN stack is a group of technologies that allow the creation of web applications by utilizing JavaScript over the front, back, and the database layer. MERN stands for:

• MongoDB – A database category which stores data within documents in a JSON format.

• Express.js – They can use a lightweight and flexible Node.js backend web application framework.

• React –It can be defined as a front-end JavaScript framework that is used to construct user interfaces that can be interacted with. 

• Node.js – A system that enables the use of JavaScript on the server side to be called and run.

The use of JavaScript on all these layers makes development obsessed and therefore make MERN the best choice for scalable web applications.

Components of the MERN Stack

1. MongoDB: MongoDB is a database that is from the NoSQL family and stores a large amount of data in JSON style. This makes it suitable for use in applications such as social networks, blogs, and other services where data scalability is of essence and immediate processing is carried out.

2. Express.js: Express is a framework for Node.js that provides a structure for the Web application server-side. It offers the routing capabilities, middleware features, and RESTful API.

3. React: We also know that React is a front-end library that is commonly used in creating interfaces that are interactive. It supports component-based development and hence could be useful in factoring out the commonality and dealing with complexity of the state.

4. Node.js: Node.js can be described as a server-side cross- platform JavaScript runtime environment. It is non-synchronized and based on events which makes it appropriate for providing real-time solutions.

Advantages of Using MERN

1. Full-Stack JavaScript Solution – It may be used for both the front-end and Back-end framework which means it is easier to learn than other languages.

2. High Scalability & Real-Time Web Functionality – It is well suited for usage in applications that have a need for timely update as in chat and collaboration platforms.

3. Flexibility & Modularity – React supports modularity since its components can be compiled more than once, making it easier to maintain.

4. Active Community Support – MERN also has a strong backing of developers providing ample support along with a variety of libraries.

5. Fast Development Time – Its use in all layers of an application makes it easy to apply the rapid prototyping and application development.

Disadvantages of Using MERN

1. Steep Learning Curve – This is true, yet to work with the entire MERN stack one needs to possess the knowledge of backend programming, state management, and databases.

2. Limited Built-in Libraries – In contrast with MEAN stack in which AngularJS has native support for some functions, React lacks a framework for it.

3. High Memory Consumption – Usually Node.js applications consume much memory and for them to be efficient on a large scale, the memory should be fine tuned.

4. Security Concerns – As a JavaScript based language, precautionary measures have to be taken to avoid things such as cross-site scripting (XSS) or SQL injections.

Real-World Examples of MERN

The leading organizations apply the MERN stack to create efficient and remarkable applications:

• Airbnb – Uses React for creating UI components to give the application user interface an interactive feel.

• Uber – Occupies Node.js to manage real-time ride requests and to track the global position.

• LinkedIn – For the backend processing of the application, Express.js and Node.js frameworks are used.

• Netflix – It provides a smooth and modern User Interface to the client baked using React for the front-end web development.
