THE COMPONENTS AT A GLANCE

MongoDB: MongoDB is an open-source, cross-platform NoSql database management system. It is a document-oriented database, thus data is kept in collections and documents. MongoDB stores data in binary JSON format, allowing for rapid data interchange between client and server. It may also be used to store enormous amounts of data, making it very scalable.

Express: Express JS is a Node JS modular, lightweight framework that aids in the development of online applications. It is a server-side, back-end, JavaScript-based framework meant to help developers create simple, quick, and secure apps.

React: React JS is an open-source JavaScript library that is used to create user interfaces for single-page applications. 

NODE JS: Node JS is a JavaScript runtime environment that is open source and cross-platform. It is intended to run the JavaScript code on the server-side, away from the browser.

A CLOSER LOOK AT THE COMPONENTS

MONGODB 

It is a document database that runs on several platforms.

MongoDB is a document database that stores data as flexible documents and has a query language based on JSON (JavaScript Object Notation). The content, size, and number of fields in the documents might vary, implying that the data structure can change over time. The MongoDB framework is well recognized for its scalability and flexibility. Check out some MongoDB use examples here.

FEATURES

Here are some of MongoDB’s features:

  • MongoDB settings are extremely scalable.
  • MongoDB may be distributed over many servers. The data is replicated to keep the system up and running in the event of hardware failure.

PROS

The following benefits of MongoDB are highlighted:

In terms of data volume and output, MongoDB scales elastically. The system provides sufficient flexibility across several data centers while maintaining high consistency.

The flexible data format with changeable schema, as well as robust GUI and command-line tools, allows developers to quickly construct and modify applications. 

MongoDB stores data in JSON-like documents, making data durability and combining simple.

Costs are considerably reduced because MongoDB operates on commodity hardware. The technology provides on-demand, pay-as-you-go pricing with yearly subscriptions, as well as global assistance 24 hours a day, seven days a week.

CONS

MongoDB does not support joins in the same way that a relational database does. However, joining functionality may be used by manually scripting it. However, it may slow down execution and have an impact on performance.

For each value pair, MongoDB maintains the key name. There is also data redundancy owing to the lack of join functionality. As a result, RAM is being used inefficiently.

MongoDB foregoes transaction functionality to gain speed and scalability. This makes MongoDB incredibly easy to expand horizontally, utilizing a large amount of low-cost hardware to balance the demand. MongoDB does not support joins in the same way that a relational database does. However, joining functionality may be used by manually scripting it. However, it may slow down execution and have an impact on performance.

EXPRESS IS A WEB APPLICATION FRAMEWORK FOR THE BACK END

Express is a Node.js web application framework. The framework makes it easier to write server code. There is no need for developers to duplicate the same code that was done previously using the Node.js HTTP module.

The express framework is intended for the development of strong and scalable online applications and APIs. Express is favored by technical co-founders, CTOs, and technology professionals due to its quick speed and simple architecture.

REACT JS

React was created by Facebook engineers. The library is used to create HTML views. Instead of utilizing templates to automate the generation of repeating HTML components, React builds repetitive DOM elements with a complete programming language. This allows us to run the same code on both the server and the browser. It distinguishes MERN from MEAN.

FEATURES

The following characteristics define React as a front-end development framework:

  • The virtual DOM is a lightweight representation of the actual DOM. All of the characteristics of the actual DOM are included.
  • One-way data binding is supported, which means that data travels in just one direction throughout the program. This gives you more power over it.
  • ReactJS is a component-based framework. As component logic is done in JavaScript instead of templates, it is simple to transfer data through the app while keeping the state out of the DOM.

PROS

  • The following benefits of the React front-end framework are highlighted:
  • The usage of virtual DOM improves the user experience and speeds up developer labor.
  • It uses a virtual DOM and re-renders just what has changed, resulting in greater performance.
  • Aids in the tight binding of values or the management of local variables vs global variables.
  • A one-way data flow ensures a reliable code.

CONS

The following are some of the drawbacks of the React front-end framework:

  • Integrating with various MVC frameworks will necessitate being aware of the configuration modifications that must be made.
  • React technologies are changing and growing at such a rapid pace that there is no time to provide adequate documentation. To address this, developers create their documentation for the technologies they use in their current work.
  • It makes use of JSX. It’s a syntactic extension that allows you to combine HTML and JavaScript. Developers and designers are dissatisfied with JSX’s complexity and, as a result, the high learning curve.

NODE JS

Google Chrome provides the foundation for Node.js, which has been open-sourced by Google. The framework is based on the JavaScript engine in Chrome. It is intended for the development of scalable network applications as well as the execution of JavaScript code outside of a browser. It works wonderfully when wrapped in an HTML page rather than utilizing its module.

FEATURES

The following characteristics define Node.js as a back-end development framework:

  • Node.js is a highly fast code execution library that is built on Google Chrome’s V8 JavaScript Engine.
  • Data is never buffered in Node.js apps. These programs simply produce data in chunks.
  • All APIs in the Node.js library are asynchronous, or non-blocking. It simply implies that a Node JS-based server will never have to wait for an API to return data.
  • Node.js operates on a single-threaded architecture that employs event looping. In contrast to typical servers, which establish restricted threads to process requests, the event mechanism allows the server to reply in a non-blocking manner and makes the server extremely scalable.

PROS

The following benefits of the Node.js back-end framework are highlighted:

  • The Google V8 engine supports Node.js and can run JavaScript in the frontend at the same time.
  • It is open-source, user-friendly, and simple to use.
  • Node.js can make it easier to utilize the web app and the server. This is because you have the same code running at the server-side end as well as the same code running on the client-side end.
  • Node.js may be used to create powerful server-side applications.

CONS

The following are some of the drawbacks of the Node.js back-end framework:

  • The application programming interface (API) of Node.js is constantly evolving. It is in no way consistent.
  • Node.js requires you to write everything from the ground up. It might lead to a loss in productivity, slowing down your job.
  • Node.js currently does not allow multi-threaded programming. It can handle far more complex applications than Ruby, although it is not appropriate for long-running computations.

After MEAN, MERN is the most common stack. Here are some of the benefits of utilizing the MERN stack:

  • It encompasses the full web development life cycle, from front-end to back-end development.
  • It helps the MVC (Model View Controller) architecture, which aids in the web development process.
  • MERN is regarded as a cost-effective stack because of its open-source support, simple setup, and decreased learning time. It may also have the lowest development cost.
  • Developers using the JavaScript stack just need to be familiar with JavaScript and JSON.
  • The four robust technologies are strong enough to support the development of full-fledged software.
