htmx Tutorial: Building Dynamic Web Apps with Hypertext Power

Htmx is a modern web framework that lets you build dynamic and interactive UIs using familiar HTML attributes. Forget heavy JavaScript frameworks; with htmx, you control server-side interactions and animations directly from your HTML, making development simpler and more intuitive.

This tutorial will take you through the core concepts of htmx, from basic AJAX requests to advanced functionalities like form validation and real-time updates.

Getting Started:

Include htmx: Add the htmx script tag to your HTML <head> section. You can use a CDN or download the library directly.

HTML

<script src="https://unpkg.com/htmx.org@1.9.10"></script>

Embrace HTML: That's all you need on the client-side! Htmx leverages HTML attributes to define interactions. No complicated JavaScript functions or frameworks.

Basic Interactions:

Sending Requests: Use hx-get, hx-post, hx-put, and hx-delete attributes on elements like buttons or links to trigger various HTTP requests.

HTML

<button hx-get="/products/123" hx-swap="#product-details">Show Details</button>

Updating the DOM: Define how the server response should be injected into the page using attributes like hx-swap (replace element), hx-append, hx-prepend, and others.

HTML

<div id="product-details"></div>

Animations: Enhance transitions with hx-target for specifying the element to update, and hx-animate for adding CSS classes for smooth animations.

Advanced Features:

Forms: Htmx seamlessly integrates with HTML forms. Use hx-include on an element to submit the form and dynamically update the page with the response.

HTML

<form id="comment-form">
  <input type="text" name="comment">
  <button hx-include="this" hx-target="#comments">Submit Comment</button>
</form>

<div id="comments"></div>

Websockets: Htmx leverages Websockets for real-time communication. Establish a connection with hx-ws and define event listeners to receive updates and dynamically render them.
Validation: Leverage the HTML5 validation API in conjunction with hx-trigger to automatically submit or trigger actions on successful form validation.
