Stack development is the norm in the IT industry today. More and more companies are leaning towards full-stack development. Many outsourcing companies that provide custom website development services are integrating full-stack development into the services they offer. A full-stack developer holds a lot more value compared to a regular developer who is proficient in a single programming language.
In simple terms, a stack is a collection of software technologies that can be used in conjunction to achieve a goal, for example, software development. MERN stack is one of the most popular stacks in the market today. If you want to leverage MERN for your business, you can either hire dedicated developers or outsource your project from agencies providing web development services. These can be local agencies or offshore agencies operating from the US, Canada, the UK, or Europe.
Who is a MERN Stack Developer

MongoDB
It's an open-source NoSQL database platform along with JSON document-based schemas. MongoDB is a distributed database that enhances its scalability and availability. It allows for easy data manipulation.
To sum up, MongoDB's features include horizontal scaling, high reliability, and end-to-end protection.
Express
Express is a web application framework for backend services. It is also known as Express.js. Express is very simple to set up and personalize according to your needs. There are a lot of supporting components to help you with additional tasks. It also assists in creating HTTP and URL-based application routes. Another important benefit of Express is that serving static resources becomes much easier compared to other frameworks in a web application.
React
React is used for front-end development. React is an open-source and free JavaScript-based library. It can be used to build interactive web pages and applications as well as user interfaces. You can manage the view layer with the help of React. A major benefit of React is that components can be encapsulated. It means that they will maintain their state independently and can be integrated to create complex interfaces.
Node.js
Node.js is a cross-platform software development tool and an open-source JavaScript runtime environment for the back end. Node.js can be used to perform tasks like creating web page content, collecting data, updating the information in the database, and managing server files. Node-js only runs one process at a time instead of creating separate threads for each new request.

Frequently Asked Questions
Here's a step-wise procedure to explain the working of an application developed using the MERN stack:
- The user lands on the page in the application created using React.
- They click on a URL that is currently in the empty state as there is no data. As soon as the URL is clicked, the data is requested using an API call. The page shows a loading GIF till the data is received.
- On the backend server, which is based on Node.js, Express searches for the data.
- Services like Mongoose are right for querying the data from the database. This database is stored in MongoDB.
- The data, once retrieved from MongoDB in the form of a JSON file, is returned to React.
- React then reloads the page with updated data to replace the loading gif.
- This is how MongoDB, Express, React, and Node.js work in tandem to provide a fully functioning web application.
Avoid these hiring mistakes when hiring a MERN stack developer:
- Neglecting cultural fit assessment.
- Ignoring soft skills like communication.
- Rushing the hiring process.
- Overlooking the importance of a technical assessment.
- Not verifying references and past work.
- Offering an uncompetitive salary.
- Focusing solely on years of experience.
- Neglecting to evaluate problem-solving abilities.
- Not considering remote work capabilities.
