1. Introduction to HTMX – web development with HTMX
HTMX is a lightweight JavaScript library that allows you to extend HTML with attributes to create dynamic and interactive web applications without writing extensive JavaScript code. It enhances your HTML by enabling server-driven interactions, making your web development process more straightforward and efficient.
Key Features of HTMX:
- Supports AJAX requests with simple HTML attributes
- Allows server-side rendering of partials
- Integrates seamlessly with existing HTML
- Enables real-time updates with WebSockets
- Supports history management and swapping content dynamically
2. Setting Up Your Environment – web development with HTMX
Before we dive into coding, let’s set up our development environment.
Prerequisites
- Basic understanding of HTML and CSS
- A code editor (e.g., VS Code)
- A web server (e.g., XAMPP, MAMP, or a simple Python HTTP server)
Installation
You can include HTMX in your project by adding the following CDN link to your HTML file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>HTMX Tutorial</title>
<script src="https://unpkg.com/htmx.org@1.8.4"></script>
</head>
<body>
<!-- Your content here -->
</body>
</html>
Alternatively, you can download HTMX and host it locally in your project.
3. Basic HTMX Concepts – web development with HTMX
HTMX extends HTML with several powerful attributes that make it easy to add interactivity. Let’s explore some of the core concepts:
hx-get
The hx-get attribute triggers an AJAX GET request when an event occurs (e.g., a click).
<button hx-get="/example" hx-target="#result">Load Content</button>
<div id="result"></div>
hx-post
The hx-post attribute triggers an AJAX POST request.
<form hx-post="/submit" hx-target="#result">
<input type="text" name="data" required>
<button type="submit">Submit</button>
</form>
<div id="result"></div>
hx-target
The hx-target attribute specifies the element where the response will be rendered.
hx-trigger
The hx-trigger attribute defines the event that triggers the request.
<input hx-trigger="keyup changed delay:500ms" hx-get="/suggestions" hx-target="#suggestions">
<div id="suggestions"></div>
hx-swap
The hx-swap attribute determines how the response content is swapped into the target element.
<button hx-get="/example" hx-target="#result" hx-swap="outerHTML">Replace Content</button>
<div id="result">Original Content</div>

Thank you for bringing this up! I think is worth adding that the core idea of HTMX is that it’s HTML “over-the-wire” – that is, returning the data formatted as HTML directly, rather than using JSON as an intermediary.
This offers several advantages:
So, in my opinion it’s likely that we’ll start reading more articles with exciting updates about HTMX and other dependency-free JavaScript libraries. I highly recommend this article from Facundo Corradini about his experience with HTMX and a brief comparison with other JavaScript libraries: scalablepath.com/front-end/htmx
