Estimated read time: 8 minutes

Are you interested in a comparison of the MEAN stack vs the MERN stack to decide which you should use in your next software development project?

You are at the right place! In this article, we will cover the MEAN stack vs Mern stack comparison in detail, including their key features, similarities, and differences.

Today, software development projects include a range of APIs, programming languages, frameworks, and libraries. Technology stacks help in maintaining compatibility between software modules of IT projects.

A complete software development technology stack also means developers get access and support to tools to develop, test, and deploy a complete software application, whether a desktop, mobile, or web app.

Two of the popular software development tech stacks include MEAN and Mern. Let’s discuss these in detail.

MEAN Stack

MEAN stack is popular for the development of responsive and advanced web and hybrid mobile applications. The MEAN stack consists of MongoDB, Express.js, Angular, and Node.js.

The MEAN stack is a free and open-source technology stack for building dynamic web and cross-platform mobile applications. It is based on JavaScript and provides several tools and plugins to develop and deploy scalable software applications.

MERN Stack

Another full-stack software development stack, competitive with the MEAN stack, is the MERN stack.

It is also a JavaScript-based open-source minimalist web framework for the rapid development and deployment of web and mobile applications. React JS helps in ensuring a near-native experience with mobile apps.

MEAN Stack vs MERN Stack – The Similarities

Some similarities that you will find in Mean and MERN development stacks include the following:

MongoDB Database Technology

Both MERN and MEAN stacks use the MongoDB database. It is a document-based database that stores data in JSON (JavaScript Object Notation) files.

It offers a flexible database model compared to relational databases and stores data in varying formats. This schema-free database model helps developers store and process varied data collections efficiently.

Backend Application

Both tech stacks use Express.js or just Express as their backend web application framework. It is an open-source framework that runs on a Node.js runtime environment.

Node.js is also based on JavaScript and is open-source. It helps with the asynchronous event-driven programming of scalable web applications.

Developers use Express to manage HTTP requests, develop APIs, etc. It helps develops single-page web applications, multi-page web applications, and hybrid applications.

End-to-End Development

MERN and MEAN are similar in a way that they both offer an end-to-end development environment. Developers get access to backend and frontend development technologies to create a complete software solution.

As both are based on JavaScript technology, there is support for a complete web development cycle from server-side development to client-side. Developers only have to write code in JS which also helps in easier switching between frontend and backend.

Flexibility and Scalability

Both development stacks help software developers in building scalable applications. However, MERN offers more scalability than the MEAN stack.

MERN uses React, based on a modular architecture. Developers can start small and easily add other components as software application grows.

Compared to Angular, which uses Typescript, React is based on JavaScript, which helps in swift integration with other tools and APIs.

Community Support

Both, MERN and MEAN stacks, have excellent developers’ community support. Being open-source, they are supported by a range of other open-source development utilities.

This development support helps software developers in swift application testing, development, and maintenance.

MEAN Stack vs MERN Stack – The Differences

Some of the prominent MEAN vs MERN stack differences are the following:

Angular vs React

The main difference between MEAN and MERN development stacks is they use Angular and React respectively. While both, Angular and React, are popular among developers, React is topping the charts for quite some years now.

With Google withdrawing its support from AngularJS or Angular 1, this lack of backward compatibility between Angular 1 and 2 also led to a decrease in its popularity in the developers’ circles.

Learning Curve for Developers

Seasoned software developers build advanced software projects with Angular efficiently. However, as compared to React, Angular presents a steeper learning curve.

Angular is a complete framework based on TypeScript and also offers its own templates for development. React is a JavaScript-based library and developers do not find it hard to work with it.

Both, Angular and React, provide documentation and tutorials for developers. However, React documentation takes the lead.

External Dependencies

Angular provides a complete development framework whereas React depends on multiple third-party integrations for added functionality. This can affect the developer’s productivity.

Angular removes the need for adding external libraries and tools and helps in efficient application development.

Angular also provides a command line interface. Upgrading a code base is relatively efficient with a CLI, which increases developers’ productivity.

On the other hand, upgrading a React code can be time and effort-consuming, given the presence of multiple third-party libraries.

Data Flow

Another difference between MERN and MEAN stack technology lies in the data flow. The data flow is bi-directional in Angular, where a change in user interface components reflects in the model state automatically.

With React, this data flow is unidirectional, which means developers can only change the UI after changing the model state.

This unidirectional data flow model helps in better data management with larger software projects.
Angular based on bi-directional data binding is feasible for developing and managing large applications giving developers more control with fewer chances of errors.

When to Choose Which From MEAN Stack vs MERN Stack?

Some of the factors that will help you choose between MERN and MEAN Stacks include the following:

Type of Development Project

Your choice between MERN vs MEAN development stacks will largely depend on the type of software application you are developing.

If it is a large enterprise-level application, then you may find using MEAN stack a better choice. It provides a systematic approach to deploying prototypes and managing large applications, like eCommerce software solutions.

Although both, MEAN and MERN, support an MVC architecture (model-view-controller) architecture, MEAN helps in the efficient management of the code base.

MERN technology stack has proved to help developers build dynamic mobile and web applications with changing project requirements efficiently.

Third-party Integrations

External API integrations are readily available with the MEAN stack whereas the MERN stack requires some extra configurations to provide support for similar libraries.

For example, Angular supports HTTP calls and connections with the backend by default. React offers its libraries for a similar purpose.

User Interface Requirements

If your software application has advanced layout features and you want to deploy complex websites with interactive UI elements rather easily, MERN is a good choice. It offers a seamless display of UI screens to the users.

React updates a virtual DOM (document object mode) to render UI swiftly, compared to Angular, which uses the real DOM.

DOM is a programming interface for web documents, including XML and HTML documents. It is cross-platform and programming language independent.

Code Advancements and Security

Angular offers better performance and developer productivity for large enterprise applications. However, React uses a component-based architecture that helps in the rapid coding and scaling of smaller-sized applications.

Angular framework in the MEAN stack offers better security standards than React in the MERN stack.
Angular provides robust security against vulnerabilities.

For example, the MEAN stack allows session cookies to remain with the client side instead of the server-side making the user interaction more secure with the application. Angular supports JSON Web Token (JWT) and allows the implementation of authorization protocols.

React does not focus on security primarily. It is built with the intention of rapid development. It offers authentication controls, however, does not provide robust security against CSRF attacks.

Are you Deciding Between Mean Stack vs Mern Stack?

As discussed above, MEAN and MERN stacks are popular technology stacks among software developers today. As MongoDB, Express.js, and Node.js are common with both stacks, the real difference lies in the use of Angular and React technologies.

Both, Angular and React, offer almost similar functionality, scalability, and productivity levels with minor differences.

Angular is well-suited for enterprise-level applications that require better developers’ productivity, minimum system administration, software utilities support, and robust security.

React sits well with startups engaged in rapid prototyping and development of dynamic applications catering to a wider user market. Component-based architecture helps to scale a software app efficiently.
