Have you ever thought about how these modern web applications are made? What is the process of making these applications? What technologies are used to build this full-stack web application? Well, you will get all your answers in this blog, where you will know what is MERN Stack, what MERN Stack technologies are, what its pros and cons are, and how to become a MERN Stack developer.
What is MERN Stack?
MERN Stack is a web development technology that developers use. It is a collection of JavaScript-based technologies used for building efficient and scalable web applications. This makes it easy for developers because they have to use a single language across the entire stack, streamlining the development process. MERN Stack consists of four key technologies;
- M – MongoDB (Database)
- E – Express (Backend Framework)
- R – React.JS (Frontend Framework)
- N – Node.JS (Runtime Environment)
What are MERN Stack Technologies?
MERN Stack is the best choice for beginners as it uses only JavaScript across all layers and simplifies the learning process for them. The MERN Stack includes four technologies, and each plays a crucial role in the development process. Let’s explain it in detail:
1. MongoDB
MongoDB is a NoSQL database product that is used to store application data. It saves information in a flexible way, which helps combine data quickly and easily. MongoDB is great for handling large volumes of data and complex structures, which are often found in web applications. It is highly scalable and flexible, and best for large amounts of information.
2. Express
Express uses Node.JS web application framework that simplifies the backend process. It is used for building APIs and makes it easy to handle server-side applications easily. Express has a user-friendly interface, which makes it easy to create web applications efficiently and it is best for beginners.
3. React.JS
React.JS is a free and open-source JavaScript library designed by Facebook, which is used for building user interfaces, particularly used to make single page applications (SPAs). It enables developers to build fast, reliable, and scalable web applications. React.js is used to create interactive frontend components for websites.
4. Node.JS
Node.js is a tool that lets you run JavaScript code outside of a web browser, usually on a server. Its event-driven model allows servers to process requests without waiting for data to be returned. Node.JS is used to develop fast, non-blocking systems.
Pro And Cons of Using MERN Stack
The MERN Stack is highly popular among developers, as it offers various advantages, but not every developer uses it. There are some disadvantages to using it also. In this section, let’s look at the pros and cons of using MERN Stack in detail:
Pros
- Easy to Learn: MERN Stack is easy to learn if the developers have detailed knowledge of JavaScript. Its development, freedom, and simplicity make it a great choice for building robust applications. Developers can benefit greatly from learning the MERN Stack.
- Scalability and Performance: The MERN Stack is suitable for building applications that can handle large databases and high traffic. MongoDB, Express and React.JS are known for their scalability and high performance, making them the best for modern web applications.
- Quick Development: With the MERN Stack, developers can use JavaScript for both frontend and backend development, which speeds up the development process. This reduces context switching between different programming languages and helps prevent potential errors.
Cons
- Learning Curve: Even though JavaScript is used everywhere each part of MERN Stack works differently and it might be tricky for beginners to learn it. Mastering all these components can be time-consuming.
- Poor Scalability: Even though MongoDB is highly scalable, poor database design can slow it down. The MERN Stack can have trouble handling a lot of data, and some developers may find it difficult to scale web applications.
- Lack of JavaScript Coding Guidelines: The MERN Stack does not have a set of coding guidelines in written. If there are not fixed guidelines, it can be hard to maintain readability, and quality of code.
Roadmap to Become a MERN Stack Developer
Web development is a top career these days. If you are passionate about becoming a MERN Stack developer, you can look at the following MERN Stack roadmap to begin your career in this field:
- Learn Foundational Languages: Begin by learning the fundamental web development languages like HTML, CSS, and JavaScript, then dive deep into the MERN Stack technologies. The main language that is used in MERN Stack is JavaScript, so you need to have a detailed knowledge of this language.
- Enroll in an Online Course: There are various options available to begin learning. Read online tutorials, enroll in online courses, and stay updated on the latest news in web development.
- Become Experts in MERN Stack Technologies: Before you start coding, install Node.js and MongoDB on your system. Learn each part of the MERN Stack one at a time. Start with one, understand how it works, and then move to the next. Study the features and workings of each technology and become an expert.
- Practice Building Projects: You must practice a lot by working on various projects. Start by building simple applications and gradually move to more complex ones.
Conclusion
The MERN Stack is a full stack JavaScript solution used for building high performing and efficient applications. By using MERN Stack technologies developers can streamline their development process and create modern web applications.
