In this Node.js tutorial for 2025, you’ll learn how to send HTML responses using the Node.js HTTP module. Whether you’re building a simple server from scratch or experimenting with how HTTP works under the hood, mastering HTML responses is a key skill for backend development.

While frameworks like Express.js simplify sending responses, understanding how to manually serve HTML content with Node.js’ built-in HTTP module gives you more control, flexibility, and insight into how web servers really work. This tutorial covers both static HTML responses and serving HTML files dynamically.

What You’ll Learn in This Tutorial:

How to set up a Node.js HTTP server without external dependencies

Using http.createServer() to handle incoming requests

Setting proper HTTP response headers for HTML (Content-Type: text/html)

Writing HTML directly into the response stream with res.write()

Ending the response with res.end()

Serving multi-line HTML templates without breaking formatting

Reading and sending HTML files from your filesystem using the fs module

Handling 404 and other custom HTML error pages

Sending HTML responses with dynamic content inserted via template literals

Difference between sending plain text and HTML in Node.js HTTP module

Real-World Examples Covered:
Sending a simple "Hello World" HTML page from Node.js
Serving a static index.html file for a landing page
Sending a dynamic HTML page showing server time or user data
Building a basic portfolio site without frameworks
Creating a minimal HTML-based API documentation page

Best Practices You’ll Learn:

Always set the correct Content-Type header for browsers to interpret HTML correctly

Keep HTML templates separate from server logic for maintainability

Use streams for large HTML files to improve performance

Implement basic routing logic to serve different HTML pages

Handle missing files gracefully with custom error HTML pages

Avoid blocking operations when reading files for responses

By the end of this tutorial, you will:

Know exactly how to send HTML responses in Node.js without relying on external libraries

Understand how to set correct headers, read HTML files, and manage response streams

Be ready to build small, framework-free web servers in Node.js
