Though it took some time to gain widespread use, Node.js has seen increasing adoption in recent years, particularly with a notable rise in popularity around 2017, which continues today.

Is Node.js a Framework? — No, It’s a JavaScript Runtime

Node.js is a runtime environment, meaning it’s a software platform that runs code and interacts with the operating system. Built on the V8 engine (which is also used in Chrome), Node.js allows JavaScript code to be executed on the server side using just-in-time (JIT) compilation. While some mistakenly refer to Node.js as a framework, this is not correct. Frameworks are designed to offer developers pre-built tools and components to streamline the development process.

However, developers working with Node.js can take advantage of various frameworks created specifically for it, such as Express, Meteor, and Sails, among others. There is a vast array of JavaScript frameworks available for backend development as well.

What is Node.js Used for?

Node.js has transformed JavaScript into a popular full-stack technology for web application development. It’s commonly used in building social networks, gaming apps, live chat systems, forums, stock exchange software, and ad servers where speed is critical. Node.js is particularly well-suited for real-time, data-heavy applications such as IoT devices and services that require scalability.

Thanks to its non-blocking architecture, Node.js excels at tasks like video and audio encoding, broadcasting, file uploads, and data streaming. This makes it ideal for industries such as travel, where aggregating data from multiple APIs is often required.

Recently, Node.js has seen increasing adoption in enterprise-level software. Although debates still exist about its suitability for large-scale enterprise use, companies like Capital One and NASA have already implemented it. The Node.js ecosystem continues to grow with tools like IBM API Connect, Triton by Joyent, N|Solid by NodeSource, and Red Hat OpenShift.

While Node.js has its pros and cons, it’s clear that no technology—whether Java, .NET, or PHP—is a one-size-fits-all solution. However, Node.js excels in real-time applications with high I/O demands, offering both speed and scalability.

Applications of Node.js

Now that you have the basic use of Node.js, let’s dive deeper into the applications that make Node.js an appealing choice for developers and software companies worldwide.

API Development

APIs are one of the most commonly used types of applications today. Nearly all web applications require a backend to interact with databases or external services. Thanks to a large community, developers can easily find libraries to create various types of APIs, such as REST or GraphQL. Previously, Node.js was only recommended for applications with low CPU-intensive operations, but since version 10.5.0, the addition of worker threads allows Node.js to handle more complex operations.

Streaming Web Applications

Streaming services are a daily part of our digital lives, enabling us to listen to music or watch videos without downloading the content. Node.js is a great choice for building data streaming applications. It includes a built-in streams module that allows you to process large amounts of data in chunks, sequentially. This eliminates the need to temporarily store or cache data in memory, and you can work with data chunks while streaming. For instance, video encoding won’t slow down the client’s experience while streaming.

Real-Time Web Applications

Node.js is ideal for handling numerous I/O operations, making it perfect for real-time web applications. For example, building a live chat room, a collaborative document editor, or even a video conferencing application becomes seamless with Node.js. This is thanks to its Event API and support for WebSockets, which allows multiple users to interact with each other in real time.

Microservices

Microservices have become a popular approach in application development. Due to its lightweight nature, Node.js makes it easy to scale your solution. It’s the preferred technology for building and deploying microservices, and many companies are migrating to Node.js when adopting this architecture. Our 2020 State of Microservices report highlights how widespread this shift is.

Command Line Tools

With the vast selection of packages available in Node Package Manager (NPM), developers can easily create both simple and advanced command-line tools tailored to their specific needs.

Internet of Things (IoT)

IoT ecosystems, such as sensors and beacons, require substantial real-time data transfer and processing. In these systems, data is exchanged between devices and servers, then from the servers to the application.

Moreover, many IoT systems involve multiple connected devices, which adds complexity in managing various tasks, including request handling and data streaming.

Node.js provides an ideal solution for building effective IoT systems, both for private and public applications.

Single-Page Applications (SPA)

A Single-Page Application (SPA) is a lightweight web app that loads a single page and dynamically updates the page’s content rather than loading new pages. This approach enhances the user experience, making it feel similar to a desktop app.

Major companies like Gmail and Twitter use SPAs today.

Additionally, SPAs are versatile, device-friendly, and capable of offline functionality.

SPAs typically employ JavaScript frameworks like Angular, React, or Vue.js for the front-end, while Node.js is used for the back-end.

Real-Time Collaboration Tools

Real-time collaboration tools allow multiple users to interact with the same application simultaneously. These tools provide solutions for project management, video/audio conferencing, app sharing, co-browsing, collaborative document editing, and more.

Examples of this technology include Trello for project management and Google Docs for collaborative document editing.

How is Node.js Different from Web JavaScript?

JavaScript, a lightweight and object-oriented language, traditionally runs in web browsers and is commonly used to create dynamic HTML pages with interactive effects.

On the other hand, Node.js is an open-source, cross-platform runtime environment that allows JavaScript to run outside the browser. But there are several more key differences between web JavaScript and Node.js:

  • Runtime Environment: Node.js is a server-side runtime environment, while web JavaScript is a client-side scripting language that executes in web browsers.
  • Use Case: Node.js is typically used to build server-side applications like web servers, APIs, and command-line tools. Web JavaScript is designed for creating interactive elements on web pages and web applications.
  • Module System: Node.js includes a built-in module system that allows developers to write reusable code and share it easily. Web JavaScript lacks a native module system, so developers often rely on third-party libraries and frameworks for web development.
  • JavaScript Engines: JavaScript can be executed by any engine that supports it, such as V8 (Google Chrome), JavaScriptCore (Safari), or SpiderMonkey (Firefox). Node.js, however, only uses Google Chrome’s V8 engine. Despite this, JavaScript code can run in any environment, as it isn’t tied to a specific browser.
  • Operating System Interaction: Node.js excels at handling system-specific, non-blocking tasks, like accessing the file system, without any OS-specific constraints. In contrast, web JavaScript can only access OS-specific features with certain objects, such as ActiveX Control in Windows.

Advantages of Using Node.js in Web Development

Advantages of Using Node.js in Web Development

Node.js has emerged as one of the most widely used web development technologies in the 2020s. Let’s explore the reasons behind its popularity in this Node.js web development ultimate guide.

  1. Strong Technology Stack
  2. Fast Processing for Web Tasks
  3. Scalable Technology for Microservices
  4. Rich Ecosystem: Node.js Libraries and Tools
  5. Strong Corporate Support
  6. Seamless JSON Support
  7. Large Developer Community and Easy Learning Curve

1. Strong Technology Stack

JavaScript continues to lead as one of the most popular programming languages, and Node.js has carved its own place within the industry. According to W3Techs, approximately 2.1% of all websites, which is over 30 million, use Node.js.

By utilizing Node.js for backend development, you automatically benefit from the advantages of full-stack JavaScript, including:

  • Increased efficiency and overall developer productivity
  • Code reuse and sharing
  • High speed and performance
  • Easy knowledge transfer within the team
  • Access to a wide range of free tools

As a result, your team becomes more adaptable, development takes less time, and the final software is fast and dependable. Developers with experience in frontend JavaScript can quickly transition to server-side programming with minimal learning effort. With the same language used on both the frontend and backend, you can easily reuse code by organizing it into modules and creating new levels of abstraction.

Contrary to popular belief, full-stack developers are not confined to the traditional MEAN stack (MongoDB, Express.js, Angular, and Node.js). The only essential component is Node.js, as it is the go-to choice for backend development in JavaScript. The other technologies within the stack are flexible and can be substituted with alternative tools that offer similar functionality (you can explore more about Node.js frameworks in our related article).

2. Fast Processing for Web Tasks

Node.js is known for its speed, and this reputation is well-deserved. Performance tests conducted by Toptal, comparing how GO, PHP, Java, and Node.js handle concurrent requests, show impressive results for Node.js. There are a few key reasons for this:

The V8 engine, which powers Node.js, was originally designed for the Chrome browser. Written in C++, V8 compiles JavaScript functions into machine code at remarkable speeds. Thanks to Google’s continuous investment in improving the engine, V8 has seen consistent performance enhancements, and Node.js takes full advantage of these improvements.

Additionally, Node.js uses non-blocking input/output operations and asynchronous request handling, allowing it to manage multiple requests concurrently, despite JavaScript being a single-threaded language.

However, this advantage is less effective for CPU-intensive tasks, which are not typically common in web server operations. We’ll discuss this further in the limitations section.

In the context of web development, the real-world examples are telling: many major companies that adopted Node.js for their applications have reported significant performance gains. For instance, PayPal experienced a 35% reduction in response time after switching from Java to Node.js.

3. Scalable Technology for Microservices

Node.js is an excellent choice for microservices architecture due to its lightweight nature. As described by Martin Fowler and James Lewis, microservices involve developing an application as a collection of small, independent services, each running in its own process and communicating via lightweight protocols, often through HTTP APIs.

By breaking down application logic into smaller components, or microservices, rather than building a large, monolithic core, you gain greater flexibility and scalability. This approach makes it easier to add new microservices on top of existing ones, simplifying the process of expanding functionality compared to integrating additional features into a monolithic app.

Node.js was recognized as a top technology for building and deploying microservice-based solutions, according to the 2017 Node.js User Survey Report. Nearly half of the respondents used microservice technologies, such as Docker (a leading platform for software containerization), to build Node.js web applications.

With microservices directly connecting to databases via streams, this architecture enhances both performance and speed. Two popular frameworks that support microservice architecture with Node.js are Express, used by companies like IBM and Uber, and Restify, employed by npm and Netflix.

For a real-world example, Walmart’s switch to a microservices architecture using Node.js led to immediate benefits, including:

  • A 20% overall increase in conversions and a 98% increase in mobile conversions
  • 100% uptime on Black Friday, handling over 500 million page views
  • Savings of up to 40% on hardware and 20-50% on overall operations

Another example of Node.js outperforming the competition is GoDaddy. During their Super Bowl ad campaign, the company managed to handle 10,000 requests per second without any downtime, using just 10% of their hardware capacity, thanks to Node.js.

4. Rich Ecosystem: Node.js Libraries and Tools

One key component of the Node.js ecosystem is npm, the default package manager, which also serves as a marketplace for open-source JavaScript tools. This plays a crucial role in the continued growth and advancement of Node.js. With over 1 million packages in the npm registry—42,000 of which are dedicated to Node.js alone—and more than 10,000 new packages being added every week, the Node.js ecosystem is extensive. According to recent data, 97% of modern web applications incorporate npm modules, highlighting the widespread popularity of Node.js among developers.

The availability of such a broad range of free tools with just a few clicks greatly enhances the potential applications of Node.js. Furthermore, the increasing popularity of open-source software offers significant advantages by enabling the development of new solutions while reducing both development costs and time to market.

5. Strong Corporate Support

As previously mentioned, Node.js was initially developed with the backing of Joyent. In 2015, the Node.js Foundation was established with the mission to “promote widespread adoption and accelerate the development of Node.js.” Founding members of the foundation include major companies like IBM, Microsoft, PayPal, Fidelity, and SAP.

The number of organizations using Node.js in production continues to grow. Today, it includes nearly 300 well-known companies, including PayPal, Medium, Trello, Uber, and Zendesk.

Few open-source projects have received such robust support from some of the world’s leading corporations, which signals the remarkable potential Node.js holds for the future.

6. Seamless JSON Support

While other backend technologies such as PHP and Ruby on Rails can use the JSON format for communication, Node.js handles it natively without the need to convert between binary models. It directly uses JavaScript, making it particularly useful when building RESTful APIs for NoSQL databases like MongoDB, which is part of the MEAN stack. This seamless integration with one of the most common data transfer standards is another significant advantage of the JavaScript ecosystem.

7. Large Developer Community and Easy Learning Curve

In 2024, Node.js emerged as the most widely used web development technology, with 40.8% of respondents in the 2024 Stack Overflow technology survey reporting that they either use or are learning it. The most popular Node.js framework, Express, ranks as the fifth most commonly used web technology, with 17.8% of survey participants indicating they use it.

These statistics highlight that Node.js has become the industry standard for web development. Companies seeking Node.js developers are unlikely to face a shortage of skilled professionals, as the active and growing community ensures that developers can find solutions to any challenge.

A major factor behind the popularity of Node.js is its accessibility and ease of learning. JavaScript, along with Node.js, is known for being both easy and enjoyable to learn. According to the same Stack Overflow survey, the majority of developers prefer to learn JavaScript-based frameworks. For example, 62.3% of respondents selected JavaScript as their preferred programming language.

Key Takeaways from Advantages of Using Node.js in Web Development

Node.js presents several advantages to web developers, including a JS only tech stack (for example MEAN), fast processing for web tasks, rich ecosystem, corporate support from companies like Microsoft, and large developer community with an easy learning curve.

Disadvantages of Using Node.js in Web Development

Disadvantages of Using Node.js in Web Development

Like any popular technology, Node.js has its share of criticisms. This Node.js web development ultimate guide describes some of the most common concerns raised by the developer community.

  1. Performance Issues with CPU-Intensive Tasks
  2. Callback Hell Issue
  3. Immature Tooling and Dependency Management

1. Performance Issues with CPU-Intensive Tasks

One of the primary drawbacks of Node.js is its inability to handle CPU-intensive tasks efficiently. To understand the root of this issue, it helps to first understand the nature of JavaScript itself.

Node.js is a runtime environment that executes JavaScript on the server side. JavaScript, originally a front-end programming language, is designed to run on a single thread because its tasks are typically lightweight and don’t require much CPU power.

In Node.js, which processes JavaScript on a single thread, this model works well for non-blocking I/O tasks. The non-blocking I/O system allows Node.js to initiate a request and handle other tasks while waiting for I/O operations to complete, using callbacks to return to the I/O tasks once the processing is done. This is facilitated by the event-loop, a core component of Node.js.

The issue arises when Node.js faces a CPU-bound task. When a heavy computational request enters the event loop, Node.js devotes all available CPU resources to handle that task before returning to process other requests in the queue. This can result in slower processing and delays, making Node.js less suitable for handling heavy computations.

However, in 2018, Node.js introduced multithreading with the release of version 10.5.0, introducing the worker threads module. This new feature allows Node.js to use additional threads from a thread pool to handle CPU-bound tasks. Worker threads enable the execution of parallel processes within the same system memory, helping offload some of the CPU-intensive tasks. While this improves Node.js’s ability to handle certain workloads, it doesn’t make the technology fully optimized for heavy computational processes.

2. Callback Hell Issue

Due to its asynchronous nature, Node.js relies heavily on callbacks, which are functions executed after a task in the queue is completed. As tasks accumulate in the background, each with its own callback, it can lead to a situation known as “callback hell.” This refers to the issue of having callbacks nested within other callbacks at multiple levels, which can make the code harder to read, understand, and maintain.

However, callback hell is often a result of poor coding practices or a lack of familiarity with JavaScript and Node.js.

To address this problem, promises were introduced as an alternative to callbacks. Promises are considered a more advanced solution and can be more difficult to implement correctly, but they offer better control and readability when handling asynchronous operations.

3. Immature Tooling and Dependency Management

While the core modules of Node.js are stable and well-established, many tools in the npm registry are of questionable quality or lack adequate documentation and testing. Additionally, the registry’s organization does not prioritize tools based on their quality or user ratings, which makes it challenging to identify the best solutions for specific needs without prior knowledge.

Since the Node.js ecosystem is predominantly open-source, this can lead to variability in the quality of tools. While the core Node.js technology is maintained by Joyent and other key contributors, many third-party tools may not meet the high coding standards expected from global organizations.

This issue is further compounded when developers are required to integrate numerous packages of varying versions, maturity levels, and support. Such challenges make dependency management particularly difficult.

In the long run, choosing to build your backend with JavaScript may result in a disorganized codebase that is hard to maintain and understand. The low barrier to entry for Node.js developers and the large pool of available talent increases the risk of hiring individuals who may not follow best practices in development.

Key Takeaways from Disadvantages of Using Node.js in Web Development

Despite its widespread popularity, Node.js comes with some drawbacks that developers should know before choosing it. 

  • CPU-intensive tasks can cause performance issues in Node.js (although multithreading in version 10.5.0 slightly solved the problem). 
  • The “Callback Hell” in Node.js is caused due to its asynchronous nature, leading to tasks accumulating in the background.
  • Despite npm being the world’s largest registry, it has many tools that are of questionable quality. As a result, developers must be extra careful to select only high-quality tools.

Node.js Web Frameworks

Node.js Web Frameworks

While extremely powerful, Node.js does not directly support some common web-development tasks. For example, if you need to handle different HTTP methods (such as GET, POST, DELETE), manage requests at specific URL paths (routes), serve static files, or use templates to dynamically generate responses, Node.js alone might not suffice. 

In such cases, you would either need to write the necessary code yourself or, more efficiently, use a web framework to simplify these tasks. With that in mind, this Node.js web development ultimate guide explores five popular Node.js web frameworks.

  1. Summary of Node.js Web Frameworks

Hello Node.js: Building Your First Node.js Application

Starting with Node.js web development can be an exciting journey for developers new to backend programming, as well as for frontend developers eager to work on full-stack applications using JavaScript. In this section, we’ll walk you through setting up Node.js, creating your first basic application, and introduce some essential tools and frameworks to get you coding confidently.

This Node.js Web Development Ultimate Guide will help you Build Your First Node.js Application in 4 Simple Steps:

  1. Step 1: Setting Up the Node.js Development Environment
  2. Step 2: Creating Your First Node.js Application
  3. Step 3: Setting Up Essential Node.js Tools and Libraries
  4. Step 4: Creating a Basic RESTful API with Express

Step 1: Setting Up the Node.js Development Environment

To begin working with Node.js, you’ll need to install both Node.js and npm (Node Package Manager) on your computer. npm is bundled with Node.js and is used to manage dependencies, libraries, and packages in your applications. Here’s a quick guide to getting set up:

  1. Download and Install Node.js
    Visit the official Node.js website and download the installer for your operating system (Windows, macOS, or Linux). It’s generally recommended to download the LTS (Long-Term Support) version for stability.
  2. Verify the Installation
    Once installed, open a terminal or command prompt and type the following commands to confirm that Node.js and npm are installed successfully:
node -v

npm -v

These commands should return version numbers, confirming the installation.

3. Setting Up a Project Directory

Create a new directory for your Node.js project. Navigate into it using your terminal:

mkdir my-nodejs-app

cd my-nodejs-app

4. Initialize a New Node.js Project

Run npm init to set up a new package.json file, which will store information about your project and its dependencies:

npm init -y

This command will create a package.json file with default settings, allowing you to start adding packages and dependencies right away.

Step 2: Creating Your First Node.js Application

Now that the environment is set up, it’s time to create a simple Node.js application. Let’s start with a “Hello World” example to understand the basics:

  1. Create the Main Application File
    In your project directory, create a file named app.js:
touch app.js

2. Write Basic Code for Your First Application

Open app.js in a code editor and paste the following code:

const http = require('http');

const server = http.createServer((req, res) => {

  res.statusCode = 200;

  res.setHeader('Content-Type', 'text/plain');

  res.end('Hello, World!');

});

server.listen(3000, () => {

  console.log('Server running at http://localhost:3000/');

});

This code creates a simple HTTP server that listens on port 3000 and responds with “Hello, World!” to any incoming request.

3. Run Your Application

In the terminal, start your server by running:

node app.js

You should see a message: Server running at http://localhost:3000/. Open your web browser and navigate to http://localhost:3000/ to see the “Hello, World!” message.

Step 3: Setting Up Essential Node.js Tools and Libraries

Node.js offers a vast ecosystem of tools and libraries to enhance development efficiency and streamline application creation. Here are a few essentials to consider as you build out your application:

  • Express.js
    Express is a minimal and flexible Node.js framework that provides a strong foundation for building web applications and APIs. It simplifies routing, request handling, and middleware integration. To install Express, use:
npm install express
  • Node Package Manager (npm) and Yarn

npm is included with Node.js and allows you to install and manage project dependencies. Yarn, an alternative package manager, is often used for larger projects where dependency management is complex. To install Yarn, run:

npm install -g yarn
  • Nodemon

Nodemon is a helpful tool that automatically restarts your Node.js application whenever files are changed. This saves time during development. Install Nodemon globally with:

npm install -g nodemon

Run your application with Nodemon by using:

nodemon app.js
  • MongoDB and Mongoose

For applications requiring data storage, MongoDB is a popular choice, and Mongoose is a library that makes working with MongoDB in Node.js easier. To install Mongoose, use:

npm install mongoose

Step 4: Creating a Basic RESTful API with Express

One of the primary uses of Node.js is to build RESTful APIs. Here’s a quick example of how to create a simple API with Express.js:

  1. Install Express
    Make sure Express is installed in your project as shown above.
  2. Set Up Routes
    Modify your app.js file to include API routes:
const express = require('express');

const app = express();

const PORT = 3000;

app.get('/', (req, res) => {

  res.send('Welcome to the Node.js API!');

});

app.get('/api', (req, res) => {

  res.json({ message: 'Hello from the API!' });

});

app.listen(PORT, () => {

  console.log(`Server running on http://localhost:${PORT}`);

});

3. Run the Application

Start the server by running:

node app.js

You now have a basic API that responds with JSON data. Access http://localhost:3000/api to see the API message.

Node.js Server Architecture

Node.js Server Architecture

The core principle behind Node.js is to enable applications to continue working even when an operation isn’t finished due to input/output bottlenecks. This technique is known as non-blocking input/output (I/O) operations. Explore the key parts of Node.js Server Architecture as part of this Node.js web development ultimate guide.

Non-blocking I/O and Asynchronous Request Handling

Consider a scenario where a function needs to retrieve data from a network, process it, and return the result. In a synchronous environment, this would cause the application to halt, waiting for the function to complete before moving on. Alternatively, other threads could be used to execute different tasks while waiting for the data.

In contrast, Node.js processes JavaScript in a single thread and handles tasks asynchronously. Rather than waiting for a function to complete after fetching data, Node.js continues processing other requests while I/O operations, like data retrieval, happen in the background. This is made possible through the use of callbacks and promises.

Callbacks and Promises

Callbacks are functions that are executed when an I/O operation finishes. Once complete, these callbacks are placed in the event queue and processed by the main thread when it’s free. While effective, nesting multiple callbacks within one another can lead to what is known as “callback hell,” making the code harder to manage. To address this, an improved method of handling asynchronous code is the use of promises. Promises allow functions to indicate that a result will be returned later, allowing other tasks to proceed without waiting for the final output.

The Event Loop

To keep the system running smoothly, Node.js utilizes an event loop. This loop constantly checks for new callbacks and incoming requests from the event queue. Once other tasks are finished, the loop processes the queued callbacks and repeats the cycle to handle new operations.

Node.js applications follow a “Single Threaded Event Loop Model” architecture, which efficiently handles multiple clients simultaneously. Its processing model relies on JavaScript’s event-driven structure, combined with the use of callbacks to manage asynchronous tasks.

What is Single Threaded Event Loop Architecture?

As mentioned earlier, Node.js operates on a “Single Threaded Event Loop Model” architecture.

In software development, many web technologies such as HTML, Ajax, jQuery, MVC, and ASP.NET follow a “Multi-Threaded Request-Response” architecture to handle multiple client requests simultaneously.

Given the prevalence of the “Multi-Threaded Request-Response” model in various web frameworks, you might wonder why Node.js takes a different approach for web application development.

How Does the Single-Threaded Event Loop Model Differ from the Multi-Threaded Approach?

In the single-threaded event loop model, one main thread is responsible for handling all client requests. The key component of this architecture is the event loop, which allows Node.js to manage blocking I/O operations in a non-blocking way. It continuously monitors the progress of asynchronous tasks and reintroduces them into the execution queue once they are completed, all within the same thread.

A developer with a basic understanding can easily implement Node.js in applications. However, a deeper insight into how Node.js works is essential for effectively designing and developing Node.js applications.

Let’s take a closer look at the components of the Node.js architecture and how a web server operates.

Components of the Node.js Architecture

  • Requests: These are incoming requests based on user actions within a web application. Requests can be either blocking (complex) or non-blocking (simple).
  • Node.js Server: The Node.js server handles incoming requests from users, processes them, and sends back responses. It serves as the server-side platform for managing these tasks.
  • Event Queue: This queue, located within the Node.js server, stores all incoming user requests. The requests are forwarded to the Event Loop, one at a time, for processing.
  • Thread Pool: This component contains available threads that perform the necessary tasks to handle client requests efficiently.
  • Event Loop: The Event Loop receives requests from clients, processes them, and sends the appropriate responses back to the users.
  • External Resources: External resources, which can include computation or data storage, may block client requests as they are utilized to complete various tasks.

Node.js Architecture Workflow

In this architecture, users or clients send requests to the server through the web application. These requests can be either blocking or non-blocking, such as:

  • Querying data
  • Deleting data
  • Updating data

Node.js receives these incoming requests and places them in the Event Queue. The Event Loop then processes the requests sequentially, determining whether they are simple enough to handle without external resources.

For simple, non-blocking requests, like I/O operations, the Event Loop processes them and sends the responses back to the respective clients.

For more complex, blocking requests, a single thread is assigned to handle the specific task using external resources. Once the task is completed, the response is sent back to the Event Loop, which then forwards the result to the client.

Key Takeaways from Node.js Server Architecture

  1. Non-Blocking I/O: Node.js uses non-blocking I/O to keep applications responsive. This means Node.js doesn’t pause when waiting for data but instead continues processing other requests.
  2. Asynchronous Processing: Node.js manages tasks asynchronously through callbacks and promises, allowing other processes to continue while I/O operations occur in the background.
  3. Event Loop: The heart of Node.js’s efficiency is its event loop, which continuously checks for completed I/O tasks and processes them when the main thread is free, enabling smooth handling of multiple requests.
  4. Single-Threaded Event Loop Model: Unlike multi-threaded architectures, Node.js uses a single-threaded model to manage client requests. It efficiently uses the event loop to handle tasks asynchronously, allowing it to serve multiple clients simultaneously.
  5. Avoiding Callback Hell: While callbacks are useful, excessive nesting can lead to “callback hell,” complicating code. Node.js introduced promises to make asynchronous coding more manageable and readable.
