Mern Stack Advantages And Disadvantages

Thinking about using the MERN stack for your projects? Before you start, it’s important to know the good and not-so-good parts of this technology combo. MERN, made up of MongoDB, Express.js, React.js, and Node.js, has its perks, like smooth development and great integration. But, like anything, it has some challenges too. In this guide, we’ll explore the pros and cons of the MERN stack, helping you understand it better and make smart choices for your web development journey. Let’s break down the upsides and downsides of MERN in simple terms!

Define Mern Stack

The MERN stack brings together both proven and modern approaches to build powerful software applications for front-end, back-end, and data systems. It relies solely on JavaScript-based platforms to create dynamic web pages and apps, making it highly sought after by companies as their preferred platform. MERN Stack is a specialization for many software development companies, incorporating advanced technologies like MongoDB, Express, React JS, and Node.js.

Express JS

It’s a server-side application framework that simplifies handling HTTP requests and responses, making it easier to map URLs to specific server-side operations. This framework for Node.js streamlines the structure by removing the HTTP module, creating a more straightforward setup.

React JS

We can make HTML -based user interfaces with the help of front-end React Javascript package

Node JS

Node.js is like a playground where JavaScript can run. It uses the speedy V8 engine from Chrome, which is the same engine MERN uses for its asynchronous language.

By having a productive backend in Node.js, you can make web app development faster and also improve loading times.

Steps To Use the MERN Stack with the Three-Tier Architecture

The MERN stack is a set of strong technologies used to create scalable web applications. With JSON and JavaScript, the MERN architecture makes it easy to build 3-tier systems, covering front-end, backend, and database components.

Front-end: React JS

At the core of the MERN stack is React JS, a JavaScript framework for creating client-side HTML applications. It simplifies the creation of intricate interfaces that connect to data on a backend server and present it as HTML using straightforward elements.

React is robust and intuitive, handling data-driven interfaces with minimal code—a distinct advantage of the MERN stack. It efficiently supports forms, lists, events, and error handling, all in one place.

Server Tier: Node JS and Express JS

One great thing about the MERN stack is Express JS, the server-side framework that works on a Node JS server. Express JS is a fast, unbiased, and lightweight web framework for Node JS. It has modules that help link incoming URLs to server functions, handling HTTP requests and responses.

To make your application better, you can use XML HTTP requests or React JS front-end POSTs to connect to Express JS functions. These functions use Node.js drivers for MongoDB to read and update data in your MongoDB database.

Database Tier: MongoDB

One of the advantages of the Mern Stack is its ability to collect data for content, user profiles, uploads, events, and comments. The Most preferable situation is to work along with the Node, Express, and React.

React JS produces the JSON files on the front end and then it is sent to the Express JS server for processing and instant archival which are available in MongoDB for Recovery. Moreover, it is possible to receive more out of the MERN stack by making a web application that depends on the system’s functional requirements.

Advantages Of MERN Stack

a. MVC

MERN stack is great because it has a simple Model-View-Controller structure, making it easy for developers to build online programs. Another important thing is that MERN applications are designed to be shared using micro-services, where each service works independently and relies on just a few others. This makes MERN ideal for creating reliable programs.

b. Full-Stack

MERN Stack tools make it easier for programmers to write programs quickly and with less effort. By simplifying API calls, developers can focus more on solving problems, adding new features, and improving the product.

With the MERN stack’s micro-service architecture, it becomes possible to describe services separately. Each service in the MERN stack handles a single task. This architectural design is excellent for programs of any size and complexity, making the MERN stack a versatile choice for various applications.

c. Easy Learning

The MERN stack is a combination of a framework, a runtime system, and a programming language. MERN is a programming language that blends the online and offline worlds. This means web developers can create powerful in-browser applications even without a browser window. MERN apps can now be run using the efficient and fast JavaScript-based runtime Node. To leverage the benefits of the MERN stack while developing online applications, MERN Stack Developers need a strong understanding of JavaScript and JSON.

d. Code Maintenance

With the MERN stack, developers can build applications that are easier to handle compared to traditional web applications. The MERN architecture has multiple tiers, making it scalable for both upscaling and downscaling without compromising code integrity. This approach not only saves time but also proves to be a cost-effective solution.

e. Strong Community

The MERN stack is gaining popularity for its ability to combine the front end, back end, and database functionalities. As its popularity grows, a supportive community is emerging to assist developers in finding the best solutions.

f. Flexibility

Using the MERN architecture is great because it allows the components of the tech stack to be open source, avoiding license problems. MERN is especially good for applications that need a clear separation of reliable data and business logic. It simplifies the code for the front end, back end, and database separately, making things much easier.

Creating Web Apps using the MERN Stack Offers

Extensive Network

This technology has a vast community. However, we can get answer through various app such as Uber, instagram , spotify and snapchat

Adaptability

Another good thing about the MERN stack is that its components are free software, so there are no licensing issues. Because many people use this tech stack, you have plenty of options for creating web applications.

React JS, a part of MERN, is known for how fast it shows things on your screen. If your website is quick, your users won’t feel like they’re waiting for things to load, whether you’re making a complex or simple software.

React is considered one of the most adaptable JavaScript frameworks. Even though there are many others, React’s code is short, clear, and easy to understand. While it might take some time to fully grasp its concepts, it’s one of the friendlier JavaScript frameworks for web developers.

Also, React’s default two-way data binding makes many features easier for you.

MERN stack vs. MEAN stack

MEAN Stack Development has been around for a while, but MERN is gaining popularity now. The MEAN stack includes MongoDB, Express JS, Angular JS, and Node JS, while the MERN stack has MongoDB, Express JS, React JS, and Node JS. The primary difference between them is Angular vs React, with Angular being a complete framework and React being a library. Comparing Angular and React is not very useful.

MERN is considered great for developing small applications, while MEAN is more suitable for larger projects. The MERN stack, using MongoDB, Express JS, React JS, and Node JS, enhances the development process for various project ideas, making the user interface more dynamic. It works well for web and mobile apps and is preferred over traditional approaches. With MERN, developers no longer need to figure out how to connect client and server sides written in different languages, making it easy to work with these technologies as they all use JavaScript.

Disadvantages Of Mern Stack

While the MERN (MongoDB, Express.js, React, Node.js) stack is a popular and powerful choice for building web applications, it does have some disadvantages that developers should be aware of. Here are some potential drawbacks of the MERN stack:

a.Learning Curve:

• Learning the entire MERN stack can be challenging for beginners, especially those who are new to JavaScript and web development. Each component of the stack has its own set of concepts and practices, making it a steep learning curve for someone starting from scratch.

b.Full Stack Development Skills:

• Building a MERN stack application requires proficiency in both front-end (React) and back-end (Node.js, Express.js) development. Finding developers who are skilled in both areas can be more challenging and might limit the pool of available talent.

c.JavaScript Everywhere:

• While using a single language (JavaScript) for both front-end and back-end development can be seen as an advantage, it can also be a disadvantage. Developers who prefer to use different languages for different parts of the stack may find this limitation frustrating.

d.Scalability Challenges:

• MongoDB, being a NoSQL database, may face challenges with scalability when dealing with complex relationships between data. Developers need to carefully design the schema and structure data to ensure efficient scaling.

e.Security Concerns:

• Security is a critical aspect of web development, and improper configurations or coding practices can lead to vulnerabilities.
