MEAN vs. MERN – What’s the Difference?

Gone are the days when CSS, HTML, and basic JavaScript were used to develop web solutions. These are no longer suitable as they fail to deliver applications with swift enhancements. End users demand a richer experience with smooth performance and a multitude of functionalities. The only way to successfully meet these ever-increasing demands is through a web stack.

What Is A Stack?

A stack is a fundamental data structure. It is linear and pursues a specific sequence in performing the operations. In a stack, deletion and insertion of items can occur only at one end, and that is top of the stack. Think of it as a pile of bricks where you can only take the topmost brick off in order to remove things from it. Similarly, the addition of brick also occurs on the top. Programming uses this stack structure throughout. The term stack gained popularity through the LAMP stack.

  • L – Linux (the Operating System)
  • A – Apache (providing server)
  • M – MySQL (relational database)
  • P – PHP (programming language)

MERN** AND MEAN – Its Elements**

Today’s web solutions are complex and need to be constantly altered and upgraded to meet user demands. Hence, the stack has also evolved to accommodate the same. MERN and MEAN are the two popular stacks used by web developers all over the world. These stand for –

**MERN: **MongoDB, ExpressJS, ReactJS, NodeJS

**MEAN: **MongoDB, ExpressJS, AngularJS, NodeJS

  • MongoDB is a Not-only-SQL (NoSQL) class platform. It is a database program which is document-oriented and used by back-end apps to store data in the form of JavaScript Object Notation (JSON) documents.
  • ExpressJS / Express is an open source software which is free. It is the de facto back-end web application framework for NodeJS.
  • ReactJS / React, developed by Facebook, is a JavaScript front-end library for constructing user interfaces.
  • AngularJS / Angular, developed by Google, is a front-end web application framework. It runs the JavaScript code in the user’s browser, letting the applications User Interface to be dynamic.
  • NodeJS is a JavaScript runtime background that permits the developer to implement the application in JavaScript at the back-end.

Benefits Of MERN

Created to develop the best in class web apps, the MERN stack is a combination of technologies. It is a JavaScript stack consisting of various open-source components which provide end-to-end framework support to application developers.

The main benefits of MEARN are:

  • The very edifice of React is a piece that preserves its form and renders itself. It’s used to build parts which the developers put together to make yet another part that shows the complete picture. By splitting the big picture into smaller components, the application developers can focus on one thing at a time. It also makes writing and reasoning about the whole application simpler. These components or parts communicate with each other by sharing data in the form of read-only properties.
  • Covers the complete web development cycle both front end (client side), and back end (server side) using JavaScript.
  • Supports the Model View Controller (MVC) architecture to allow a smooth development process flow.
  • Since the JavaScript stack is used, the developers need to have proficiency in JavaScript and JSON only.
  • Uses four of the most viable technologies, i.e., MongoDB, ExpressJS, React, and NodeJS.
  • Has a wide range of pre-built testing tools.
  • Is an open source framework, and supported by a dedicated community.
  • React allows the same code to run on the browser and server both. This is possible only because of its isomorphic nature. It means when the occasion arises, you can create pages on the server.
  • React is a library and not a framework. A framework has set parameters and allows the developer to create an app as guided by them. However, a library gives complete freedom to the developer to design the app as they deem fit picking and choosing from the multitude of library’s functions.

Benefits Of MEAN

MEAN is one of the fastest growing combinations of technologies. Equipped with responsive tools and plugins, MEAN reduces the time spent on managing the systems. Some of the most complex websites and application built today use it for faster deployment.

The main benefits of MEAN are:

  • Transferring code written in one framework to another is usually very difficult. MEAN makes it easy.
  • MEAN is so flexible that it allows easy testing of applications on the cloud platform. Applications can not only be designed and tested but also introduced on the cloud. By adding a field to the form, the developer can also add more information.
  • Covers the complete web development cycle both front end (client side), and back end (server side) using JavaScript.
  • Supports the Model View Controller (MVC) architecture to allow a smooth development process flow.
  • Web application development is more fluid and organized by doing away with all the needless grunt work.
  • Uses four of the finest technologies, which includes MongoDB, Express.JS, Angular.JS, and Node.JS.
  • Has a wide range of pre-built testing tools.
  • Is an open source in framework, and is supported by a dedicated community.
  • MEAN is cost-efficient because it just requires proficiency in JavaScript.
  • MEAN allows easy switching between client and server. It also permits the launching of an application directly on the server minus any deployment to a stand-alone server.

MERN Vs. MEAN – The Difference

The main difference between MERN and MEAN boils down to the choice between React or Angular. React framework is lightweight and specifically designed for seamless development of web user interfaces which are either single or multi-page and hybrid. As against this, Angular is mostly used in Single Page Applications (SPA) to deliver unbroken and smooth user experience as it sanctions rendering the complete page without the need to refresh it.

Final Thoughts

MEAN has been in the market far longer than MERN but MERN is slowly picking up in popularity. Both MERN and MEAN are sound and viable options. However, the final choice should depend upon the demands of the project and the application developer’s familiarity with the technologies involved. Since both are open source and use almost the same technology combination, it is a matter of deciding between React and Angular.

Authentication In MEAN Stack - A Quick Guide

I consider myself an active StackOverflow user, despite my activity tends to vary depending on my daily workload. I enjoy answering questions with angular tag and I always try to create some working example to prove correctness of my answers.

To create angular demo I usually use either plunker or stackblitz or even jsfiddle. I like all of them but when I run into some errors I want to have a little bit more usable tool to undestand what’s going on.

Many people who ask questions on stackoverflow don’t want to isolate the problem and prepare minimal reproduction so they usually post all code to their questions on SO. They also tend to be not accurate and make a lot of mistakes in template syntax. To not waste a lot of time investigating where the error comes from I tried to create a tool that will help me to quickly find what causes the problem.

Angular demo runner
Online angular editor for building demo.

Let me show what I mean…

Template parser errors#

There are template parser errors that can be easy catched by stackblitz

It gives me some information but I want the error to be highlighted

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

AWS v/s Google v/s Azure: Who will win the Cloud War?

In the midst of this pandemic, what is allowing us unprecedented flexibility in making faster technological advancements is the availability of various competent cloud computing systems. From delivering on-demand computing services for applications, processing and storage, now is the time to make the best use of public cloud providers. What’s more, with easy scalability there are no geographical restrictions either.

Machine Learning systems can be indefinitely supported by them as they are open-sourced and within reach now more than ever with increased affordability for businesses. In fact, public cloud providers are increasingly helpful in building Machine Learning models. So, the question that arises for us is – what are the possibilities for using them for deployment as well?

What do we mean by deployment?

Model building is very much like the process of designing any product. From ideation and data preparation to prototyping and testing. Deployment basically is the actionable point of the whole process, which means that we use the already trained model and make its predictions available to users or other systems in an automated, reproducible and auditable manner.
