MEAN Stack vs MERN Stack? How to Choose the Right Tech Stack

When it comes to developing an app, you need to choose between MEAN stack and MERN stack. But what is the difference between these two? What are their key features, and which one should you choose for your business?

The challenge – choosing the right technology stack for your app development

Choosing the right technology stack for your app development is a critical decision. An app experience – mobile or web – is far from a monolithic structure. Apps are built using a set of programming languages, frameworks, libraries, plugins, tools, databases and much more. The permutations and combinations of different tools produce entirely different results.

Depending on your specific outcome needs, your business requirements and many other factors, you choose a specific combination of technologies and this selection is called your technology stack. What tech stack you use depends on factors like:

  • Your project requirements (such as whether you need to support multiple platforms or native functionality)

  • Development and maintenance cost (for example if you want to reuse existing code)

  • Scalability (how your application will perform under high load)

  • Security (how safe is it from hackers)

  • Time to market (how quickly can you build the product)

The MEAN Stack

MEAN stands for MongoDB, ExpressJS, AngularJS and NodeJS. These are all open-source technologies that can be used separately or together to create web applications. The MEAN stack was created by Valeri Karpov in 2011 as a way of combining these four technologies into one cohesive unit that can be used to build single-page web applications. It's also known as MERN: MongoDB, ExpressJS, React/React Native/AngularJS plus NodeJS (hence the confusion).

Advantages of Mean Stack

MEAN stack has many advantages over other frameworks. It offers great flexibility, scalability and reusability. This means that it will work well with both small and large projects alike.

It is also very cost-effective as it allows startups and small businesses to save money on their software development projects which are often expensive.

The best part about MEAN stack is that it can be used for both server side development as well as client side development which means that developers can switch between the two sides easily without having to learn a new language or framework each time they want to switch sides on the project. This makes it easy for them to complete their tasks quickly without any issues or delays in production time due to switching between languages or frameworks all the time!

The MERN Stack

MERN stands for MongoDB, ExpressJS, React/React Native/AngularJS plus NodeJS (hence the confusion). It's similar to MEAN but adds React or React Native into the mix. Both stacks use JavaScript as their main programming language and both can produce amazing results on their own or combined with other tools such as Electron or Cordova.

Advantages of Mern Stack 

MERN Stack is a JavaScript-based technology stack that provides developers with all the tools needed to create modern, powerful web applications. MERN has been gaining popularity as it offers various benefits to developers, such as:

• Excellent community support

• React Library

• Model-view-controller architecture

• No context switching

• Easy learning curve 

These features make MERN an ideal choice for app developers looking to build next generation apps.

MEAN or MERN: What should you choose?

There is no doubt that MEAN stack has been a popular option for developers who want to build web applications.

But with the recent rise in popularity of MERN stack, it is important to understand which one better serves your business requirements and which you should choose.

So let’s roundabout some of the key differentiators between MEAN stack and MERN stack to find out which one better serves your business requirements and which you should choose.

What’s better – MEAN stack or MERN stack?

When it comes to choosing between Angular and React, you should consider your needs and preferences.

In many ways, Angular holds the upper hand in scalability, testing, code upgrading and profitability. React on the other hand offers two major advantages – easy learning curve and closer to native experience.

So if you are old school and enjoy the unified development experience of Angular, you may invest more time in learning Angular and choose MEAN stack. If you prefer the easier learning curve and prefer the native experience of React apps, MERN is your answer.
