MERN Stack vs Full Stack: Understanding the Concepts
In this world of rapidly evolving web development, the terms MERN stack and Full Stack are most frequently used. These tech stacks offer different types of advanced technologies employed to create stunning web applications. Knowing the difference between Full stack and MERN stack is essential for business agencies and web developers to pick the most suitable one for their requirements.
MERN stack is referred to as a Java-script-based framework that builds different and user-intuitive web applications. The four major components or elements of the MERN stack are MongoDB, Express.js, React, and Node.js.
The function of MongoDB is to maintain the database smoothly, while React is responsible for creating robust user experiences. Express.js helps in managing the backend, while Node.js is responsible for managing the server side of the application.
If you are interested in building highly interactive, scalable, and fast web applications, then you must make use of the MERN stack instead.
The term Full Stack is referred to as the complete set of advanced technologies and tools that are highly recommended for building stunning web applications. The major elements of Full-stack include Frontend, Backend, and Database.
The major function of Front-end is to interact easily with users by using advanced tools such as CSS, HTML and JavaScript. The backend helps in managing data processing, server communication, and logical integrations using advanced tools such as Python, Node, and PHP.
The database helps to collect data like content or the details of users using MongoDB and MySQL.
Key Differences Between MERN Stack vs Full Stack
I have tried to illustrate the difference between Full stack and MERN stack in the below section stating their key features and where they distinguish themselves. I have highlighted the major elements of both tech stacks to make your development journey easier on which to choose for the betterment of your development project.
Let’s start by grasping the vital elements of each one below;
The MERN stack is comprised of four different elements, including Node.js as the runtime environment, React for the frontend management, Express.js for the backend management, and MongoDB for the database management. This JavaScript-based tech stack has a fixed stack.
On the contrary, Full Stack does not belong to any particular tools or technologies. There are huge amounts of options available to web developers for each layer, such as PostgreSQL or MySQL for databases, Vue or Angular for the front end, and Laravel or Django for the backend. MERN stack is less expensive than Full Stack due to its lower flexibility.
Developers of the MERN Stack should be professional or skilled in JavaScript as it is frequently employed by all of its elements. Web developers should have expertise in MongoDB for the database, Node.js for the backend, and React for the front end. However, a wide range of skills or expertise is highly essential for developers of Full Stack.
They must be familiar with different types of popular programming languages like Ruby, PHP, or Python, based on the tech stack they choose. Their expertise and skills often cover a range of advanced frameworks, databases, and deployment tools, making them more flexible than MERN developers.
The MERN Stack is specially crafted to scale in environments that use JavaScript. It is highly recommended for medium-sized development projects and single-page web applications that require to be created fast and seamlessly.. Although, for business-level web applications, its scalability can be limited.
On the contrary, Full Stack offers higher scalability based on selected technologies. It is highly suitable for a range of web applications, including large business systems, and allows modification. Full Stack has a benefit in handling different types of scaling needs due to its higher flexibility.
MongoDB, React, Node.js, and Express are the four essential JavaScript-based technologies employed by the MERN Stack. These web development technologies offer a continuous environment and are closely linked.
On the contrary, Full Stack covers a huge range of advanced technologies. Based on the demands of the web development project, full stack developers can pick any particular database, such as MySQL or PostgreSQL, Django or Angular for the front end, and Laravel or Flask for the back end. The versatility of Full Stack makes it more challenging but also more dynamic than MERN stack.
MERN stack web applications need hosting solutions that are highly compatible with Node.js. Excellent choices are Heroku, AWS, and Vercel, which fit best with JavaScript environments.
On the other hand, Full-stack hosting highly depends upon the selected tech stack. The projects in full stack developments should use shared hosting services such as cloud solutions, such as AWS or VPS, based on advanced technologies. The full Stack provides higher hosting opportunities than the MERN stack. In contrast, the predetermined environment of the MERN stack makes it easier for the application in platforms that are highly dependent on JavaScript.
A MERN Stack developer excels expertise in developing front-end, back-end, and database web applications integrating the popular single programming language, JavaScript. Their responsibilities are limited to the advanced technologies used in the Stack.
On the other hand, the scope of Full Stack developers is broader than the MERN stack. They integrate with a range of advanced tools, frameworks, and databases, often integrating different technologies into a single web development project. Due to this, full-stack job roles are highly complex and demand familiarity with scalability and deployment, often in DevOps techniques.
Both of the tech stacks have different architectures. MERN stack follows a single-language architecture, which is more streamlined than other tech stacks. This specific architecture helps in easier inter-layer communication.
On the other hand, there are different types of architecture are there in Full-stack development, and they include, Three-tier Architecture or Model View Controller (MVC) model. These excellent architectures help full-stack developers manage complex web applications demanding incompatible structural features.
It is easier for web developers to perform tasks over all components of the MERN Stack without changing programming languages as it is fully JavaScript-based. Based on the tech stack, Full Stack, however, can cover multiple programming languages.
For the database, web developers can use SQL, MySQL, Python for the back end, and JavaScript for the front end. In contrast to MERN Stack’s uniformity, full-stack developers should learn and make use of different types of programming languages due to their higher flexibility.
The MERN Stack integrates React to make fluid, fast-loading single-page web applications with a focus on engaging and dynamic user experiences. It fits well for user-focused layouts due to its built-in advanced tools or technologies.
On the other hand, Full Stack offers you more flexibility when it comes to building better user experiences. Any frontend framework must be chosen by web developers to meet specific demands. Though it can take additional planning to achieve similar flexibility, Full Stack’s adaptability makes it highly recommended for a wider range of web applications.
Modern JavaScript-based web applications with features such as real-time updates and fast rendering are made possible with the use of the MERN Stack. It is the best fit for functions that require stunning content and responsive designs.
On the other hand, Full Stack offers web developers the necessary skills to use a variety of tools for a diverse range of web development project demands, which leads to a broader feature set. As compared to the MERN stack, it is highly flexible and suitable for web development projects that require a range of features, from complex backend tasks to highly engaging user interfaces.
JavaScript-based advanced security features are employed in the MERN Stack to protect the major elements of React, such as MongoDB databases and Node.js servers. Cross-site scripting (XSS) issues are required to be addressed actively by web developers. The tools and technologies employed highlight the security strategies for the Full Stack.
Multiple layers of security can be employed, like backend frameworks with inbuilt security features such as Laravel or Django. For more complex web applications, Full Stack can often be highly secure due to its multi-layered security layouts.
There is an active and growing community for the MERN Stack, especially among the developers of JavaScript. A large amount of resources and support are available for React with Node.js.
On the other hand, the flexibility of Full Stack enables it to have a broad and more diverse community of developers. Full Stack makes it very easy by offering assistance for developers who employ any combination of advanced stack technologies. In contrast to the MERN stack, the toolkit of Full Stack ensures a wider range of informational resources and continuous support.
MERN Stack vs Full Stack: Which Is Better?
However, both Full Stack and MERN Stack are strongly recommended to you if you are aiming to develop a stunning website or web application. The demands of the development project will figure out which is most suitable.
As JavaScript is employed more frequently in all tiers, the MERN Stack is right for development projects that require a single language. It is highly recommended for stunning, single-page web applications, making programming simpler while ensuring accuracy. It works well for newly launched businesses and fast development due to its predefined technologies.
Although Full Stack performs better for intricate, different development projects, it allows web developers to choose the right technologies based on certain parameters. It is suitable for business-level web applications due to its higher scalability and flexibility. Both the tech stacks offer excellent employment opportunities and strong community support.
