In the previous part of the article on MERN Stack Development Complete Guide Part 2, we talked about how using the MERN stack for your development projects offers numerous benefits, including versatility, cost-effectiveness, and access to a large community of developers. Whether you're looking to enhance your existing team's capabilities or streamline your development process, understanding the cost dynamics, strategic hiring, and potential of outsourcing is crucial.
Now, moving further in this final part we’ll cover the role and responsibilities of a MERN stack developer, essential skills for a MERN stack developer, how to find them and what are the essential tools used to develop a MERN stack web application.
So, let’s begin the discussion, first let us briefly understand what MERN Stack development is to set a little base.
The MERN stack stands out for its flexibility, efficiency, and comprehensive JavaScript environment for developing online applications. It enables developers to use JavaScript throughout the stack, promoting code reuse and simplifying the development process. Here's a brief overview of each component in the stack:
MongoDB provides a flexible and scalable database management solution.
Express.js streamlines the coding and implementation of back-end components, making server-side programming easier.
React is known for its component-based architecture and quick updates, allowing developers to create dynamic and engaging user experiences.
Node.js: Allows for quick, event-driven server-side programming, providing smooth interaction between the front and back ends of applications.
The MERN stack provides a consistent and comprehensive framework for developing full-stack JavaScript applications, allowing developers to create modern, responsive, and high-performing web experiences. The combination of these components takes advantage of their distinct capabilities to provide complicated functionalities and provide improved performance.

Now, let us understand what are the roles and responsibilities of a MERN stack developer?
We at Acquaint Softtech can help you find the MERN stack developer with the right skills.
A MERN Stack developer is responsible for a number of tasks, one of the main out of all is developing a web application’s front end as well back end developments. They ensure everything works as per plan as it should and there should be no bug, if incase any bugs are present it can be fixed quickly.
Below we’ve covered a few primary responsibilities of a MERN Stack developer:
The first responsibility is to work as a frontend as well as a backend development partner.
They should develop features and fix the bugs.
They are responsible to add new features to any existing application, thus removing old ones, as and when required by business needs.
Moreover, they should also look to implement standards, technologies and frameworks.
The task of creating mockups and new features is also driven by a MERN stack developer.
Nexty, they are responsible for testing the finished product for bugs before the final release.
They also write cross-platform and cross-device compatible code
Completing understanding of Rest APIs.
Now, further let us understand what are some technical skills required to become a proficient MERN Stack developer.
A developer who is well-versed with this MERN stack can easily find the job and build web application products. Therefore, every MERN Stack developer requires some essential technical skills.
Below are some essential set of technical skills any MERN stack developer should learn:
Programming languages skills are JavaScript, HTML5 and CSS3
Database management skills are MongoDB, MySQL or PostgreSQL
Frontend framework development skills are ReactJS, VueJS, AngularJS, EmberJS, NodeJS, BackboneJS and ExpressJS for any backend development
They also should have knowledge about Object-oriented programming.
Now, from an organization’s perspective let us understand how you should run the screening and interviewing process to follow before you hire MERN stack developer.
Firstly, you’ll have to determine the skills and experience required for the MERN stack developer. Moreover, you can use a questionnaire for screening or interviewing questions to identify candidates that meet your minimum requirements.
Moreover, you can ask the developers for an initial phone interview, however it should be just considered as a formality and not a major factor for decision making in the hiring process.
If any candidate passes the initial screening, they will move to the next round which is an interviewing round. This interview round will focus on determining if the candidate is a good fit for your company and if you are a good fit for them.
You can question them about their experience with MERN stack technologies and any other necessary abilities (such frontend development) during the interview.
Make sure you enquire about any initiatives they have worked on and the outcome of those endeavors. Additionally, you want to search for proof that they have developed code in the past (such as personal GitHub accounts).
Try, if you can, to provide questions that need action (creating some code, for example).
Now, further let us learn what are the 5 best tools to use if you are a MERN stack developer
Having the appropriate tools is crucial for improving development experience, efficiency, and productivity. We will discuss the five most crucial tools that any MERN developer needs to have in this post. Because of its efficiency, scalability, and flexibility, the MERN stack is one of the most often used in full-stack web development.
So let us begin by knowing the 5 best tools every MERN Stack developer should have. The first one in the list is
Visual Studio code is the best code editor tool across a number of domains, and every MERN stack developer should use. It has a few powerful sets, including syntax highlighting, code completion and an integrated terminal. Moreover, it has an extensive library full of extensions, specifically for MERN Stack developers that provides debugging, version control with Git and a seamless integration with Node.js and React.js projects.
One of the best tools for API development is Postman, and it is a crucial component of MERN stack projects. Postman makes testing, debugging, and documenting APIs easier, whether you're using Express.js to create RESTful APIs or communicating with other APIs. You may submit queries, check replies, and automate testing procedures with its easy-to-use UI.
For any MERN stack app, a MongoDB compass is the most considered database in storing and managing the data. The combination of a MongoDB Compass and a GUI tool provides a visual interface to interact with different databases and collections.
You may interact with your MongoDB database with different graphical user interfaces. Moreover this easy-to-use interface, you can execute queries, examine and analyze your data to improve performance. A MongoDB Compass is an efficient database management tool for developers of all skill levels.
The foundation of the MERN stack is React, and for debugging React apps, React DevTools is an essential component. The browser plugin for Chrome and Firefox facilitates the development of React applications. It lets you track real-time component updates, observe component state and properties, and examine React component hierarchies. It's an essential tool for building well-structured and functional React apps.
In Node.js projects, npm is a crucial tool for managing packages and dependencies. Installing, managing, and updating third-party libraries and modules is made easy with npm. In addition, you can write your own programs and packages. Package.json files can be used to specify project dependencies, and npm can take care of the rest. Making sure the MERN stack project you're working on is built on reputable, up-to-date packages is crucial.
In the area of MERN stack development, having the right tools can significantly boost output and enhance the development process's satisfaction. The following five tools are essential for any developer working with the MERN stack: Visual Studio Code, Postman, MongoDB Compass, React DevTools, and npm. You'll be able to produce dependable and efficient web apps faster by incorporating these technologies into your workflow.
