Technology evolves every day, and the demand for effective web applications is increasing with it. Developers now aim to create these applications better to benefit users in their desired way. This is why mobile and web app developers use new frameworks and platforms to create highly interactive applications. The development stack has indeed made the work for developers pretty simple. What is a stack? It is a combination of the latest technologies, which includes frameworks, databases, libraries, etc., to provide full structural development. One of the numerous utilized stacks today is MERN. It is a MEAN stack variation, a more modern and full-stack used by MERN stack app developers. Using this technology stack, app developers can create highly functional and efficient applications to fulfill users’ needs. The increase of dynamic requirements from users can be catered to quite easily now.

It is an open-source development stack that comprises back-end, front-end, and database components. This stack is backed up by Javascript, making it user-friendly and used by many startups. The three-tier architectural construction becomes easy to use. Let us now break it down to understand what the name MERN itself means. This acronym is used for four technologies. They are the following;

  1. MongoDB- A Document Database
  2. Express JS- Node.js Web Framework
  3. React JS- Client-side JS Framework
  4. Node JS- A JS Web Server

Let us move forward and learn more about each component in detail that makes up the MERN stack.

  1. MongoDB- A Document Database

MongoDB is a non-relational (NoSQL) document-oriented database storing data in BSON form. Name-value pairs are stored here the same as JSON documents. It can easily store a vast amount of data quite easily; it is a cross-platform database, which makes it even more effective. It is mainly known for its flexibility and scalability.

Why Use MongoDB?

  • The primary reason to use MongoDB is the freedom to store any kind of data in various documents easily.
  • With the process used here, called sharding, it becomes possible to store vast amounts of data. The data is distributed across many servers, making it easy to store it effectively.
  • This database is admiringly scalable, with data not being kept in rows and columns.
  • Because of the indexing feature, developers do not need to search the full document, which increases overall speed.
  • Environment setup is much easier than RDBMS; also, because the community is broad, you can always get help.
  • It becomes easier to use by developers because it is based on Javascript.

MongoDB does not support complex joins, but code can be written for the same. LinkedIn, McAfee and Adobe are using MongoDB, which indicates its importance.

  1. Express JS- Node.js Web Framework

It is a middle and application tier/backend Node.js framework. This saves the MERN stack app an extra mile to write the webserver code. Here, you do not have to repeat the Node.js HTTP module. Using it, you can easily create web-based applications and APIs. The explanation for its vogue is that it is short and quite fast.

Why Use Express JS

  • js support is fortunate, and the NPM containers cause the development strategy to be easy.
  • Because the debugging is quite fast, the developers can easily find all the errors and get them fixed.
  • It is asynchronous.
  • The process of developing and testing becomes more manageable because it is single-threaded.
  • It also has a broad and widespread community available to provide assistance.
  • Build-in routers ib this framework make the code reusability quite effective.
  • The robust APIs make the work go faster.
  1. React JS- Client-side JS Framework

This change is the reason for the variation of the MERN stack from the MEAN stack app technology. Now, developers use ReactJS instead of the old-fashioned AngularJS. Facebook introduced this framework used for the front-end development in the market. People use this library to build creative user interfaces and single-page applications. JSX or Javascript XML is an HTML extension used to React so that components can be easily written.

Why

Should You Be Using It?

  • The outpour of the date in a single direction makes the code fully stable.
  • It has such a high-performing rate, making it a top choice for MERN stack app developers.
  • It contributes to both mobile and app development user interfaces because of the code reusability.
  • User experience is enhanced, and developers can work faster because of Virtual DOM.

The large community support makes Reach the most loved framework. It being open-sourced is another cause for its vogue in the market. According to a survey, 74.5% of developers prefer to use React.

  1. Node JS- A JS Web Server

A beneficial cross-platform JS runtime environment that is open-source. Developers can choose from a multitude of available modules. This subsequently increases the efficiency of web applications. Developers can create a scalable network with quite ease.

Why Use Node JS

  • The code execution is quick because Node JS is assembled on Chrome’s V8 javascript engine.
  • The server based on Node.js never waits for APIs to return data because they are asynchronous.
  • This is highly scalable, just like other components of the MERN stack.
  • It is very uncomplicated to utilize because it is single-threaded.

Conclusion

Every cross-platform app developer understands that each line written in JavaScript on both the server and client-side makes it convenient and provides a significant advantage to the developers. The learning time is reduced and becomes cost-effective because it is open-source. If you want to build a loaded, scalable, and competent web and mobile application, the MERN technology stack is the best option you have.
