MERN Stack is fast becoming a populate choice for applications built in web3, but what is it, what are the alternatives and how does it compare? We go in to detail in this Ultimate Guide for businesses looking at how the MERN components could be the right framework for your next project.
What is MERN Stack?
MERN Stack is an acronym representing four pivotal technologies: MongoDB, Express.js, React.js, and Node.js. Together, these technologies provide a full-fledged framework to build sophisticated web applications. Here’s a brief on what each component brings to the table:
MongoDB: A NoSQL database that ensures flexibility and scalability in managing data.
Express.js: A minimal and flexible Node.js web application framework that simplifies the creation of robust APIs.
React.js: A JavaScript library renowned for its efficiency in building interactive user interfaces.
Node.js: A JavaScript runtime environment that facilitates building scalable network applications.
Why This Guide?
The objective of this guide is to provide a comprehensive insight into MERN Stack development for businesses exploring viable solutions for their development requirements. Whether you are looking to revamp your existing web application or embarking on a new project, understanding the capabilities of the MERN Stack is crucial in making an informed decision. Moreover, with the advent of web3 technologies, the MERN Stack’s compatibility with blockchain technologies and smart contracts further amplifies its appeal.
In the following sections, we will delve deeper into the intricacies of MERN Stack, its alignment with web3 technologies, and how it can be the catalyst in fulfilling your business’s development aspirations.
How do MongoDB, Express.js, React.js, and Node.js work together to create full stack web applications?
Here’s a breakdown of how these technologies collaborate to create a full-stack web application:
MongoDB:
MongoDB is a NoSQL database that stores data in a flexible, JSON-like format. It’s designed to handle large amounts of unstructured data, making it a good fit for modern web applications that require a flexible schema for efficient operation.
Role: Data Storage and Management.
Operation: Stores data for the application, handles CRUD (Create, Read, Update, Delete) operations, and ensures data integrity and availability.
Express.js:
Express.js is a minimal and flexible Node.js web application framework that provides a robust set of features to develop web and mobile applications. It facilitates the rapid development of robust APIs.
Role: Back-end Application Framework.
Operation: Manages server-side logic, interacts with the database, processes client requests, and sends appropriate responses back to the client.
React.js:
React.js is a JavaScript library used for building user interfaces, particularly single-page applications where you need a fast, interactive user experience.
Role: Front-end Library.
Operation: Renders the user interface, manages user interaction, and displays data from the server in a visually intuitive manner.
Node.js:
Node.js is a JavaScript runtime environment that allows developers to execute JavaScript code server-side. It’s built on Chrome’s V8 JavaScript engine and helps in building scalable network applications.
Role: Server Environment.
Operation: Hosts the server and manages the communication between the front-end and back-end, enabling the execution of JavaScript code on the server-side.
How Do These Components Work Together?
Request Handling:
A user interacts with the React.js front-end of the application, triggering requests to the server.
These requests are sent to the Express.js layer hosted on Node.js, which processes these requests based on the defined routes and logic.
Data Processing:
If the request requires data retrieval or manipulation, Express.js interacts with MongoDB to execute the necessary CRUD operations.
Once the data is retrieved or manipulated as needed, Express.js receives the results and processes them as required.
Response Sending:
Express.js then sends the appropriate response back to the React.js front-end.
React.js processes the response and updates the user interface accordingly, providing a dynamic and interactive user experience.
Continuous Interaction:
This cycle of request-response continues as the user interacts with the application, ensuring a seamless and interactive user experience.
The synergy between MongoDB, Express.js, React.js, and Node.js in the MERN stack provides a streamlined development process, making it easier to build, maintain, and scale full-stack web applications.
