What Web Server Does Node Js Use?

When building a web application with Node.js, understanding the underlying web server is essential. Node.js, as a JavaScript runtime built on Chrome’s V8 engine, does not come with a built-in web server like Apache or Nginx. Instead, it provides a set of powerful modules and APIs that allow developers to create their own web servers.

Node.js Core Modules

Node.js has several core modules that can be used to create a basic web server:

  • HTTP Module: The HTTP module in Node.js allows you to create an HTTP server that listens for incoming requests and handles them.
  • HTTPS Module: Similar to the HTTP module, the HTTPS module allows you to create an HTTPS server for handling secure connections.
  • Net Module: The Net module provides low-level network functionality and can be used to create TCP or UNIX socket servers.

NPM Packages for Web Servers

In addition to the core modules, there are several third-party NPM packages available for creating web servers in Node.js. These packages often provide additional features and flexibility:

  • Express: Express is one of the most popular and widely used frameworks for building web applications in Node. It provides a simple and intuitive API for creating robust web servers with features like routing, middleware support, and template engines.
  • Koa: Koa is another popular framework that aims to be smaller, more expressive, and more modular than Express.

    It uses modern JavaScript features like async/await and generators for writing clean and readable code.

  • Hapi: Hapi is a rich framework for building web applications and services. It emphasizes configuration-driven development and provides a powerful plugin system for extending its capabilities.

Choosing the Right Web Server

When deciding which web server to use with Node.js, it’s important to consider your project’s requirements and your familiarity with the different options. If you need a lightweight and straightforward solution, the core modules might be sufficient. On the other hand, if you’re building a complex application that requires advanced routing, middleware support, or other features, using a framework like Express or Koa can save you time and effort.

In conclusion,

Node.js itself does not come with a built-in web server. Instead, it provides core modules like HTTP and HTTPS that can be used to create basic servers.

Additionally, there are popular third-party frameworks like Express, Koa, and Hapi that offer more advanced features and flexibility. Understanding these options will help you choose the right web server for your Node.js projects.
