The MERN stack consists of four programming languages that are similar to each other and that can be used together in the same project to create web applications and services. They are MongoDB, Express, React, and Node.js, which is how it got its name (MERN).
It is a popular stack for building web applications and some popular MERN stack website examples include Airbnb, Uber, and Netflix. MERN developers are in high demand due to the popularity of the stack, and they can command high salaries.
If you're looking for a comprehensive guide to becoming a MERN developer and learning MERN stack web development, look no further. This article will help you learn more about the MERN stack and why it has become so popular among web developers over the past few years.
In this blog post, we'll introduce you to the MERN programming benefits and provide examples of how developers can use it to create amazing web applications. Plus, we'll discuss the career opportunities available for a MERN developer, how to become one through a MERN stack development course, and the skills you'll need to learn to be successful in this field.
The components of MERN stack
The elements of the MERN programming stack include:
MongoDB is a NoSQL database that stores data in the form of documents, with key-value pairs similar to JSON objects. With MongoDB, you can create databases, schemas, tables, and more.
ExpressJS is a NodeJS framework that enables and makes it easier for writing the code for the backend. It eliminates the need to create multiple node modules. To keep your code concise, ExpressJS provides a lot of middleware.
Why you should learn the MERN stack web development
If you're ready to start your journey down an exciting career path, you should consider learning about MERN. After all, according to Upwork's Skills Index, demand for MERN developers is on track to increase by nearly 85% from 2017-2021.
This software stack can be used for web development of everything from blogs and e-commerce sites to news portals and business applications. The core principles behind MERN are modularity, scalability, and high availability. The idea is that each individual part of the project can be updated independently while other modules remain unaffected.
For example, if there's a bug in one module that needs to be fixed, it doesn't affect any other modules until it's been patched up or replaced with an entirely new module with that bug fixed.
As always, practice makes perfect so try making some small projects using these technologies so that when interview time comes around you'll have something impressive to show off.
A comprehensive MERN stack development course will help you get started with the basics and set you up for building a successful career in the field.
Features of the MERN stack
MERN developers love it because it makes building websites easier than ever before. In fact, this development stack is one of the most popular ones in use today.
It is completely open source. That means you have access to all of its code, so you can tweak and customize it as needed. If you work in an organization that relies on proprietary software, then being able to modify it will help reduce your costs and make future updates easier.
The built-in functionality of these technologies allows you focus on creating new features or improving what's already there - not reinventing wheels every step of the way.
MERN stack is known for its flexibility and has been used in everything from simple landing pages to complex enterprise applications and is considered one of the fastest-growing technologies today. You can build anything you want with it, and it allows you to switch out modules as needed based on your needs.
If you are looking for something highly technical, like encrypted authentication or Active Directory support, then you can add that functionality easily while reducing development time overall. And if your application needs only basic functionality, then you won’t pay for extraneous code.
A key reason why MERN developers choose this stack over other alternatives is its focus on accessibility over everything else. It aims to be inclusive of people who may not have a strong background in programming, making it easy for anyone to get started with the basics.
It has libraries like Handlebars for templating and jQuery for DOM manipulation, meaning you don’t need any prior experience with those languages to get started.
Skills You Need to Know for MERN Stack Development
When looking to learn to build applications with the MERN stack, either on your own or through a MERN stack course, you should ensure that these skills and tools are covered:
- HTML - Hypertext Markup Language that allows developers to create and format web pages
- CSS – Cascading Style Sheets allow users styling of html elements
- SQL – Object-relational database management system (ORDBMS) that lets developers manipulate data stored in a database. In order to fully understand how MongoDB works, you should first learn SQL.
- Java – Object-oriented programming language that’s widely used for enterprise systems, apps development and Android app development
- Python – Programming language designed for code readability for more complex tasks; widely used in machine learning, natural language processing, predictive analytics, operations research and modeling.
And hiring developers with a MERN stack certification who are familiar with these technologies means that these companies don't have to waste time and money training them on how to use various frameworks - allowing them to add features and push updates faster than ever before.
The Advanced Certificate Program in Full Stack Development with MERN and Cloud Computing offered by Hero Vired, in partnership with edX and from Harvard University is a great program to get started with.
This MERN stack course helps you learn how to build applications end-to-end. Over a period of 7 months, you get access to 50+ live sessions with the industry-experienced faculty, 15+ case studies, and a capstone project.
Moreover, this MERN stack certification program will help you find a job in the field of software and web development as a MERN Developer or related roles through its Placement Assurance services.
