Everything You Need to Know About MERN Stack.pptx
Today, the web application development process is
not the same as it was a couple of years back. Web
apps are developed using various technologies, and
one of the common technologies we all might be
aware of is 'Technology Stack.' It is often used in
modern software development. But what does it
actually mean?
Technology stack refers to the amalgamation of
programming languages, tools, and frameworks
used in software development. If you usually work
with a tech stack, you will surely have a favorite one
you always pick when developing a web application.
If it is the MERN stack, you’re also one of those
developers who find this technology stack the right
choice to win the race in 2022.
According to the HackerRank development skill
report, 30% of developers choose Angular.js while
26% stayed with React JS. The report also highlights
that 30% of the programmers show interest in
learning ReactJS, whereas 35.9% of developers
prefer to use ReactJS for development. These stats
clearly show that the MERN stack stands slightly
above MEAN when it comes to popularity. Not only
this, but MERN also stays on top of the chart in terms
of ease of understanding.
But why is the MERN stack so popular among
developers? In this blog post, we will talk about the
MERN stack development and some frequently
asked questions about this tech stack.
What Is MERN Stack Development
In today’s fast-evolving world, developers have gone far beyond
building web and mobile apps using JavaScript, HTML, or CSS.
They have jumped to more modern approaches, tools, newer
databases, development frameworks, and runtime environments.
MERN stack is also one of them that offers numerous benefits,
including faster development time and improved performance.
MERN Stack Explained
MERN stack is an open-source web development framework
and Javascript stack designed to create web and hybrid mobile
applications and make the development process more
straightforward and faster deployment.
MERN stack is layered up with the four technologies -
MongoDB, Express.js, React.js, and Node.js. This tech stack
offers an end-to-end framework to developers, providing all the
components that play a crucial role in web applications
development.
Use Cases Of MERN Stack
The bonus point of this
technology stack is that it is also
suitable for those cloud-based
applications that require an
interactive internet interface and
a lot of JSON. Well, the MERN
stack is used for a variety of
reasons that you should know
before choosing it for your next
project.
1. Interactive Forums
No matter whether you want an interactive forum for a
webpage or social networking website, choosing MERN
would be a great idea. It can create these forms that will
allow people to post messages or chat with people on the
other end or perform several actions.
2. Calendars & To-Do Lists Apps
Developing any calendar or to-do application is fun with
the MERN stack. ReactJS can be used to create a calendar
and the frontend and user dashboard of the to-do
application. MongoDB helps save, read, change and show
data or information within your to-do app.
3. Social Media Products
MERN stack also helps create products for social
networking sites. These products may include interactive
forms, for instance, a little web app integrated within the
social network page, Ads, articles, etc.
Components of MERN Stack development
The four key technologies that make up this MERN stack are MongoDB, Express.js,
ReactJS, and Node.js. Let’s take a deep look into these technologies-
1. MongoDB
● An open-sourced document-based server, MongoDB is a NoSQL as well as
Non-Standardized Query Languages) database. But what does NoSQL refer to?
● MongoDB also offers new methods for data extraction and storage.
● MongoDB employs JavaScript as just a development language that gives a
reason to say yes to this tech stack.
● No table structures are available in MongoDB that are basically found in
RDBMS (Relational Databases Management Solution).
● The data is stored in BSON (Binary JS Object Notation) format. This BSON
format specifies the length and information type that helps it process faster.
● This technology stack component is also quicker than RDBMS (Relational
Database Management Solution) because of the indexing algorithm and
effective storage quality.
● But at the same time, it is crucial to understand that MongoDB can’t handle
complex transactions because advanced join procedures aren’t accessible in this
technology stack.
● MongoDB is a most popular form of NoSQL system that scores high in terms of
scalability and is well known for providing the high-performance.
● It also provides access to a customizable document model that any developer
can generate in no time.
2. Express.js
● Express.js is a Node.js framework and one server-side
infrastructure for JavaScript that runs under js.
● This technology stack is designed to build APIs of web
apps, and cross-platform mobile applications faster.
● It is considered another great JavaScript framework
perfect for backend development.
● It provides the ease to build and manage reliable servers
and is considered a perfect tool to develop mobile
applications rapidly.
● This component of the MERN stack makes it
convenient for developers to create advanced and
complex APIs (Application Programming Interfaces)
and web servers.
● Structuring the software’s functionality can also be
accomplished with Express using routing and
middleware on powerful web servers.
● It also has useful features that enhance Node.js HTTP
(HyperText Transfer Protocol) items.
3. ReactJS
● React is a renowned and popular open-source front-end JS
library for building web applications.
● Before developers use React, it is crucial to meet some
prerequisites, such as installing the newest version of Node
modules on your machine. Not only this, but a developer
must be familiar with HTML, CSS, and JavaScript.
● React is not only a JavaScript framework. It’s a basic
JavaScript library created by Facebook that can easily
overcome difficulties other libraries are unable to handle
when developing online and smartphone apps.
● This technology is also used to take control of any view
layer for smartphones and online apps.
● ReactJS has been used to create user interfaces, particularly
for single-page web apps.
● Developers utilize the power of this technology to construct
UI (User Interface) components that can also be reused.
4. Node.js
● Node.js is not a coding language, hence it is not a
framework.
● This technology is used to build a number of
backend solutions, including web apps and mobile
apps.
● Today, several tech giants such as Uber, PayPal,
and Netflix reap the benefits of this technology.
● It is also considered a reliable open ASCII text
storage platform that everyone can use.
● It can work on various operating systems whether
it is Windows or Mac OS X, Linux, or Unix.
● Super easy to run and is suitable for agile design
and prototyping.
● Node.js gives consumers extremely fast services
necessary in the competitive online world.
