Among the most important traits of web development is that it is adjustable to meet new circumstances that occur on the market. Well, various new tendencies will emerge over time, and you need to understand how to implement them in your web-building projects.

In this day and age, it is an absolute must to have a website that can satisfy all the needs of the customers. For you to achieve that, following the latest trends should be on the list of your priorities. Naturally, this is not something you can achieve easily. Therefore, keeping a lookout for them is an absolute must.

Of course, it means that you either hire developers who have knowledge of a certain branch, or you provide education to the staff you already have. Today, we want to discuss [MERN stack development](https://www.mongodb.com/mern-stack), what is it, and how it can benefit your project. Without further ado, let’s take a look at what is important to know about this approach.

**The Basics**

Before we can understand the benefits of this approach, we need to understand the concept fully. Well, the MERN is a string of refined methods that are used for building software applications. What needs to be understood is that this approach utilizes three main categories, data system, backend, and front-end aspects.

All of them will be done through the use of JavaScript platforms, with the addition of active web apps and pages. For that reason, it has become quite a popular approach in the last couple of years. Among the technologies you can come across in this one, you can find numerous well-known ones.

Therefore, developers need a complete understanding of all these technologies, and some others we haven’t mentioned here if they are to be successful. As you probably know, these technologies are quite versatile, and it cannot be said that you can understand all of them if you know just one. Now, let’s see what the most important segments of MERN are.

**MongoDB**

Creating a document-oriented database is another important segment for a vast majority of apps out there. Implementing these makes it possible for apps to store data by using technology such as JSON through the use of dynamic schemas. Also, adding new data is done without rewriting the existing code.

You can achieve this by [using MongoDB](https://potado.co/mongodb-development-singapore). We are talking about a technology that offers consistent reads and writes for the whole app. Also, it provides high availability by keeping a high number of copies of documents for different machines. For that reason, using MongoDB is quite widespread.

**Express.js**

Another important framework that needs to be taken into consideration when we are talking about MERN is Express.js. We are talking about a lightweight and fast framework, which makes it possible to make all the server-side to be as fast as possible, which is of the utmost importance.

At the same time, it doesn’t need too many resources to conduct these activities. The reason is quite simple, its architecture is not as complex and it doesn’t require too much time and resources to be built. An experienced developer can build it in no time, and utilize it to serve the needs of the app.

**ReactJS**

ReactJS is a UI-creation library that uses JavaScript, which was developed at Facebook. It is used for the creation of big apps, whose data tends to change over time. The best thing about [ReactJS development](https://potado.co/reactjs-development-singapore) is that you have probably used it a high number of times and that you haven’t even noticed this was the case.
We are talking about the most widely used web framework. 

Numerous studies can confirm that they are present in a high number of projects. Probably the best-known cases of implementing this approach are Yahoo Weather and Instagram. Therefore, you can see that there are many examples of them working properly.

**Node.js**

Creating network applications is significantly more challenging than some other types. If you are about to embark on a journey to create one of these, chances are you will use a JavaScript runtime environment known as Node.js. Using these makes it much simpler to conduct this sort of development.

One of the cases when using these is an absolute must is when you want to create a cross-platform app. For instance, if you want to create something that will be available for all the major operating systems and platforms, [Node.js development](https://potado.co/nodejs-development-singapore) is the way to go. That’s why it is important to use this one in projects such as these.

What are the Benefits?

Now, we want to shine a light on the benefits of MERN.

**Flexibility**

The most important benefit of MERN is that offers the possibility for the mechanisms of the technology stack to be open source. Therefore, a community that focuses on them can provide some useful solutions, without any restrictions. Naturally, you will choose which one of these solutions is useful in your case.

Another thing regarding the flexibility benefit of this approach is that it offers you a chance to make a clear distinction between business logic and data itself. Better yet, it offers the possibility to make a clear divide between different aspects of the project. We have already talked about these techs in greater detail earlier.

**Budget-Friendliness**

Projects who are to be made while the company is on a [limited budget](https://potado.co/blog/app-development-cost-singapore) should always think about working with full-stack developers, including those who are well-versed in MERN stack development. That way, they can get a professional who can take care of numerous sides of the project on its own. This is why many new [startups develop their MVP](https://potado.co/startup-app-development-singapore) using React on the frontend and Node on the backend.

Naturally, coming across these employees is not an easy thing to do in most cases. But when possible, it should become a priority for every company. The amount of costs that can be deducted in this case is exceptional, and this is why MERN stack development is so popular.

**The Bottom Line**

Before you are ready to embrace MERN, you should know all the relevant aspects of it. Here, we’ve presented you with some of the most important ones. We are sure you will find them useful in your future projects.
