Of all the tech stacks, MERN Tech Stack is one of the best app development frameworks out there. In fact, it’s the choice of framework for most startups and small businesses. But why is it so popular? What makes MERN better than other tech stacks? Let’s find out!
That being said, we are here to dive into the world of technology and understand which tech stack is best for your next software development project. Let’s get it started!
A Closer Look at MERN Tech Stack
With the surge in the number of web and app projects, the underlying technologies are constantly evolving to keep up with the ever-increasing competition. Consequently, the development world has gone through tremendous changes over the past decade, resulting in cutting-edge tools, technologies, and stacks.
One of these tech stacks is called MERN Stack development, which is quite popular among startup businesses that want to build robust applications without any hassle. As a JavaScript stack, it encompasses four main components:

1. MongoDB
MongoDB is a document-oriented database, which uses a JSON-based language to build innovative web applications. The database comprises various sizes, fields, and content, making it a No-SQL database. This is what makes MongoDB flexible, scalable, and easy to use.
Top features of MongoDB include:
- MongoDB has built-in scalable environments.
- It can run over multiple servers.
- It comes with Master-Slave replication.
- It stores data in flexible JSON-like documents.
- It uses native apps to maintain multiple copies of data.
- It duplicates data for any potential hardware failure.
- Costs are low as MongoDB runs on commodity hardware.
2. Express.js
It is an open-source web framework, which builds scalable and fast applications. These apps are generally written in Java and you can install them in Node.js. In other words, they will be in the browser or middleware.
Top features of Express.js include:
- It is super-fast and highly scalable.
- It is an asynchronous and single-threaded.
- It helps with code reusability by using a built-in router.
- Express.js comes with a robust API.
3. React.js
Developed by Facebook to build larger applications, React.js is the most used web framework out there, with 40% of worldwide developers. Furthermore, it is a view layer in MVC that can build repetitive DOM elements with JavaScript.
Top features of React include:
- React provides a stable code.
- The code is written in templates.
- It has all the properties of the real DOM.
- The framework supports one-way data-binding.
4. Node.js
The fourth component of MERN Tech Stack is Node.js, which is a JavaScript runtime environment. It can build network applications and contains an event-driven architecture.
Also, Node.js uses non-blocking I/O operations that can ably minimize overhead and enable access to multiple requests at the same time.
Top features of Node.js include:
- Node.js is built on Google Chrome’s V8 JavaScript Engine.
- It makes use of a single-threaded model with event looping.
- Node.js apps never buffer any data.
- All APIs of the library are asynchronous.
Why Startups Opt for MERN Stack Development?
Let’s face this: 9 out of 10 startup businesses usually fail. In fact, 2 out of 10 businesses fail in the first year. Here, tech problems are one of the biggest killers. For instance, not having the right tech stack and lacking a creative team of Full Stack developers would ruin your start-up business. This is where MERN Tech Stack can save your day.
Here are a few good reasons why MERN Stack is made for startups.
Reason 1: MERN is Open-Source
All four MERN Tech Stack components are open-source, so you do not have to worry about licensing problems. These components are kept up-to-date with the help of experts. Plus, the underlying benefit of using MERN lies in no vendor lock-in. This means startups can easily change or move to another vendor without incurring expenses or dealing with a tedious process.
Reason 2: It is a Type of Full Stack
Yes, MERN leads to end-to-end development by offering a full-stack development environment. This means startups do not have to worry about other technologies or tools. They get everything in the MERN Tech Stack itself. Cool, isn’t it?
Reason 3: It has its Own Testing Tools
MERN is available with its own testing tools suite, allowing full stack developers to test the application with the testing tools provided within the framework. Also, MERN supports Model View Controller architecture, which makes it easier to develop workflow.
Reason 4: It is backed by a Great Community
MERN has a huge community of full stack developers. This is simply because it’s a JavaScript framework with tons of resources available online. Each one of these resources is well-documented and provides answers to the queries people raise.
Reason 5: It is Flexible and Easy to Maintain
Since all four components of the MERN Stack development are open-source, you can build applications without worrying about the dispute regarding licensing. Furthermore, the stack provides an amazing opportunity to startups regarding code maintenance. With an abundance of powerful testing tools, you can test and maintain your apps in a cost-efficient way.
Reason 6: It is Quite Easy to Learn
What else makes MERN Stack development special is the fact that it’s easy to learn and implement. The learning curve becomes simpler when you are already familiar with JavaScript. On top of that, the availability of tutorials, documents, and community support helps new learners in the pursuit of expertise.
Reason 7: It Gives a Native Experience
Native apps are considered more secure and robust, so MERN Tech Stack gives a native experience to users. It uses native features to ensure streamlined data sync between offline and online applications. Hence, startups can easily monetize with native apps as they have to invest time in creating them rather than fixing them.
Reason 8: It is faster than Other Frameworks
According to PayPal, an app built with Node.js took half the time to respond. It required 33% fewer lines of code than a Java app. In other words, Node.js has an event-driven architecture that allows for various concurrent requests with less slowdown. This makes the MERN Tech Stack faster compared to its competitors like LAMP and Ruby on Rails.
Reason 9: It Uses Isomorphic Code
JavaScript is the most widely used programming language with around 64.96% of respondents. In MERN Stack development, you can go for isomorphic coding with the help of JavaScript. You can transfer the code written in one specific framework to another. This is because JavaScript is a common language for both the client-side and server-side, which makes it easier to understand the data flow through the components.
Reason 10: It Offers Next-level Security
As the number of cyberattacks are rising, keeping your web app safe and secure should be the paramount priority while choosing a web stack. And when it comes to security, MERN Tech Stack is the framework to rely on. It has MongoDB’s non-relational database, which is not prone to SQL injection. Additionally, Node.js maintains a variety of channels to address the security of the development project.
The Bottom Line: You Can’t Go Wrong With MERN Tech Stack
This leads us to the end of this blog post, where we briefly explained why MERN is great for startup apps. We hope all these reasons are more than enough to prove that MERN is a viable tech stack for any startup. Have a question or project to discuss?
