MERN stack is a package of four technologies for quicker and more efficient web application development. It is used across the globe by developers who want to access tools via JavaScript only during the web application development process. Since a full stack developer operates both the front and the back end, the MERN stack is all the more helpful. For instance, the back-end development uses a database, while the front-end processing requires a framework. Therefore, creating a web application using MERN is helpful because it includes a database and a library with frameworks for front and back-end development. Furthermore, it is beneficial for beginners as they only have to learn JavaScript (or JSON) to navigate through all the tools in the MERN stack.
What Does MERN Stack Do?
MERN stack makes web application development easier and more efficient. It consists of four open-source programs with community backing, all based on JavaScript. MERN is an acronym which makes up the names of the programs it consists of.
These are as follows:
MongoDB
MongoDB is described as a modern database on its official website. It is scalable and fast and offers easy database management irrespective of the project size. Express.js Express.js is based on Node.js and provides optimum performance for web application development. However, it is primarily used for single-page web applications.
React
React is used at the front end and helps create interactive web applications. In addition, it helps create projects that are unique and require new source code rather than relying on existing frameworks.
Node.js
Node.js is a fast back-end development tool which is used for complex web applications. A runtime environment enables a developer to create a website that will run across platforms.
Why Is MERN Stack Important?
While there is no shortage of databases or frameworks in the industry, there is a reason why the MERN stack is highly preferred by developers worldwide. MERN stack and MEAN stack have similar compositions with one marked difference. While the MEAN stack employs the Angular framework, the MERN stack uses the React library. React library is preferable because it allows developers to be creative with their programs and create something unique without necessarily following a predefined framework.
MERN stack is an essential addition to the full-stack web development community because of the following reasons: It Saves Time And Money It is helpful for developers to save time while developing a web application if they use the MERN stack and are well-versed in all the features of the programs. Since all programs are based on JavaScript, it is helpful to create a web application without switching languages or creating different codes for the front and back ends. From the point of view of an employer, the MERN stack would save money as they would need to hire developers familiar with JavaScript. Since all programs use JavaScript, the necessary expertise must be in related programs that the MERN stack offers.
Open Source Tech All the programs in the MERN stack are open-source technologies. It is extremely convenient for developers to use open-source technologies during the processing stage. Whether it is MongoDB or React, the programs are supported by large communities with members around the world. One key benefit of strong community backing is the ease with which you can seek solutions for an existing problem. Chances are, someone went through something similar and fixed it earlier. In addition, numerous portals for communicating and sharing code among developers exist.
