Open source programming and JavaScript, in particular, might appear to be a place where blast and bust is the rule of thumb. However, Node.js is a one-of-a-kind programming language. But the question arises as to why node.js should be used. And the rationale behind it is that Node.js now thrives in real-time online applications that use web rockets and push technologies. Even though it is not new and its progress has not been spectacular, it has managed to establish itself as one of the most widely used JavaScript tools in the last few years. It is now also used in database applications due to which nodejs MySQL has become one of the most popular ones.

This post is for you if you want to learn how to connect node.js to MySQL or have a better knowledge of what is node.js. Let’s dive in to learn more about it.

What is Node.js?

Node.js is a cross-platform, open-source JavaScript runtime environment that allows JavaScript code to be executed outside of the browser. It is an excellent web framework for novices since it is well-suited to data-intensive applications such as streaming and real-time apps, and makes it simple to begin developing the back-end.

Users can utilize JavaScript everywhere and on any browser like Linux, macOS, Windows while using Node.js. And to mean everywhere, it refers to the front-end, middleware, and even the back-end. As a result, Node.js is included in several major web development frameworks, including MEAN, MERN, and MEVN stacks.

Features of Node.js

In the process of learning about what is node js, features are the main aspects that need to be understood. These include:

  • Google Chrome V8 JavaScript Engine

This is a runtime engine that is used to create a runtime environment. The Chrome V8 JavaScript engine transforms JavaScript into readable code in the same manner as a Java Virtual Machine does.

  • Event-driven & Asynchronous

APIs present in the node.js library is completely in the non-blocking form or asynchronous. A server is written in node.js never has to wait for data from an API. The server goes on to the next API after visiting one.

  • Single-Threaded

Node.js is scalable because it uses a single-treaded design with event looping. Unlike traditional servers that establish restricted threads to handle requests, the event mechanism allows the node.js server to respond in a scalable manner.

  • Quick execution of Code

The V8 JavaScript Runtime motor, which is also utilized by Google Chrome, is used by Node.js. The Hub offers a wrapper for the motor, allowing the runtime to execute more quickly. As a consequence, the preparation of requests in Node.js becomes more efficient.

  • Fast Streaming

When data is sent in several streams, it takes time to process. Node.js is a rapid data processing framework. It concurrently processes and uploads a file, which saves a lot of time. As a result, Node.js boosts data and video streaming performance.

  • No Buffering

Data in the Node.js application do not buffer.

Functions of Node.js

While learning what is node.js, it is critical to comprehend its functionalities. Node.js thus can perform:

  • Data collection is from forms.
  • The data in the database is updated, destroyed, and added.
  • For websites, it generates dynamic content.
  • Files here are generated, read, written, removed, and closed on the server.

Fundamentals of Node.js

Now that we have known, what is node.js, let’s explore its fundamentals:

  • Console
  • Buffer
  • File system
  • Event Loop
  • Globals

Use of Node.js

The domains where Node.js is proven to be an excellent technological partner are as follows:

  • Applications that are I/O bound
  • Streaming Data Applications
  • Applications based on JSON APIs
  • Single Page Applications

Reasons to Learn Node.js

If you are following along, the main question is whether you should learn Node.js. To help you decide whether now is the right time to start learning JavaScript, here is a list of the most convincing reasons:

  1. Demand in the Market
  2. Very easy to Learn
  3. Utilized for Full Stack Development
  4. Easier to compass JavaScript on both server and client-side
  5. Versatility
  6. Develop applications without complex code
  7. Appropriate to building Microservices

Connect Node.js to MySQL

While learning about what is node.js, another area that draws much attention is the way to connect node.js with MySQL. 


  1. To begin, create a node.js project in the appropriate location on the computer.
  2. In the project, the folder downloads the MySQL module.
  3. After that, use the MySQL module’s creating connection function to create a database connection.

Why connect node.js with MySQL?

There are several reasons why using node.js with MySQL for data storage is a good idea:

  • Being an open-source database, users do not have to contribute anything to use MySQL.
  • MySQL is a strong database. It can do things that the most costly and powerful solutions can do.
  • MySQL is compatible with several operating systems and languages, including Java, PHP, and others.
  • MySQL is fast, even with enormous data volumes.

What to learn next?

It would have been unthinkable just a few years ago to conceive of being able to connect with a database from a client-side environment based on JavaScript. Such functionalities were only available through server-side technology. This tiny revolution that happened is only due to Node.js.

Now that you’ve mastered the fundamentals of Node.js, including its essential tools, functions, purposes, and motivations to study it, you’ll need to understand the HTTP modules, Node.js modules, file system, and NPM dependencies.

A good next step towards learning can help you gain a deep insight into node.js and the related aspects. Following the concepts of node.js REPL, publishing a package, node.js, and OS, Node.js MySQL, building a functioning app and packages will thus help you to become a node.js expert.
