MERN Stack vs Full Stack Dev

MERN Stack vs Full Stack Development

Full-stack means end-to-end application Software Development, including Front-End and Back-End. In contrast, MERN Stack is a technology stack allowing more efficient, quicker, and easier learning curve development. Today, we'll clarify your doubts and show you the features of each term, helping you find the ideal option to run a smooth development process.

What is Full Stack Development?

Before diving into MERN and Full-Stack, it's necessary to understand their core. Full-Stack means end-to-end application Software Development, including Front-End and Back-End. While the Front-End encompasses all related to what the user sees and interacts with, the Back-End handles the business logic and application workflows.

For example, if you're building a retail website where users buy, add, or remove items from a shopping cart, it's vital to build good User Interfaces with HTML, CSS, and JavaScript! In the back-end, you can use programming languages such as Java and Python to handle all the processes the user normally doesn't see. On top of that, don't forget about scalability, event handling, and routing. You can use libraries and frameworks like Django and Spring Boot to work on these.

Main Types of Development

1. Front-End Development. These developers handle the UI, including visual effects, navigation, frameworks, and forms. Besides using HTML, CSS, and JavaScript, Front-End devs work with techs like Vue.js or React Native, depending on the digital product they want to create.

2. Back-End Development. They're focused on business logic, security, performance, scalability, and handling request-response of the application. Back-end developers create or use frameworks to design principal app workflows with techs like Python, ROR, and Java.

3. Full-Stack Development. They're responsible for encoding end-to-end workflows using front-end and back-end technologies such as MERN Stack, LAMP Stack, and MEAN Stack, allowing them to create end-to-end apps.

What is the MERN Stack?

The MERN Stack is an acronym for MongoDB, Express, React, and Node. These technologies combined are capable of building complex applications from scratch. Using this stack, you can control databases and server-side programming to API routing. It provides a comprehensive framework for developers who search for all the tools they need in one place. 

MERN Stack Components

1. MERN Stack Interface. Developers use React.js libraries to develop interactive front-end interfaces based on data with minimal coding. It's perfect for creating complex UIs, handling errors, and managing forms and lists using simple components.

2. MERN Stack Back-End. At this level, Express.js, which runs on the JavaScript server of Node.js, serves URL routing, HTTP requests, and response handling. In other words, it handles all the tasks of server-side development.

3. MERN Stack Database. You need an easy-to-work database with other stack technologies to store data for your MERN projects. For the MERN Stack, MongoDB comes into the scene as a valuable player with its scalability and complete security. It's the perfect solution to send, store, or retrieve data.

Full Stack vs MERN Stack

There's a lot of misinformation when talking about MERN Stack 2023 and Full-Stack Development. Full-Stack Development is an approach where developers use different development stacks (LAMP, MEAN, or MERN) to achieve a developed product without needing other technologies. No need to say this is not strictly this way; you can use other languages or frameworks if required.

On the other hand, the MERN is a full-stack JavaScript-based technology, therefore, it already belongs to the full-stack development stacks. In simple words, Full-Stack Development would be like the trunk of a tree and MERN one of the tree's many branches. So, it's up to choose the right type of approach and technologies depending on the type of project the development team works on, the difficulty level required, and the budget it entails.


Remember, there's no ideal technology; it all depends on the context in which you use it. You must consider your needs, budget, and requirements to choose the best option. In this case, we can help you determine which programming language and technologies are perfect for your application development requirements.
