All about HTMX, a JavaScript library that allows you to build web applications with modern, dynamic user interfaces.

HTMX is a JavaScript library that allows you to build web applications with modern, dynamic user interfaces while keeping the server-side rendering and simplicity of traditional web development. It's often used in conjunction with HTML, Python, and other server-side technologies.

What IS HTMX - Tutorial provided by AppSeed.

Here's a basic overview of HTMX and how to get started:


You can include HTMX in your project by adding the HTMX script to your HTML file. You can either download it and host it locally or include it from a CDN (Content Delivery Network). Here's an example of including HTMX from a CDN:

<script src=""></script>

Adding HTMX Attributes

HTMX is primarily used by adding attributes to your HTML elements. These attributes tell HTMX how to handle interactions with the server.

The most commonly used attributes are:

  • hx-get: Fetch data from the server using a GET request.
  • hx-post: Send data to the server using a POST request.
  • hx-trigger: Define the event that triggers the request (e.g., click, input).
  • hx-target: Specify where the response from the server should be inserted.

Here's an example of a button that makes an HTMX request when clicked:

<button hx-get="/endpoint" hx-trigger="click">Fetch Data</button>
<div hx-target="#result"></div>

Server-Side Handling

On the server-side, you need to create endpoints that HTMX will interact with. These endpoints can be implemented using your preferred server-side language (e.g., Python, Node.js, PHP).

When an HTMX request is made, the server should respond with the necessary data or HTML.

Handling Responses

HTMX allows you to specify where the server's response should be placed in the HTML document. You can use the hx-target attribute to identify the target element. For example:

<div hx-target="#result"></div>

The server's response will be inserted into the element with the id="result".

Additional Features

HTMX offers many other features like handling form submissions, dynamic updating of content, animations, and more. You can explore these features in the HTMX documentation.

Sample Project

To help you get started, you might want to create a simple project or experiment with HTMX. Start with a small project, and gradually explore more advanced features as you become more comfortable with the library.


  • HTMX Documentation: The official documentation is a great resource for learning more about HTMX and its capabilities.
  • HTMX GitHub Repository: You can find the source code and examples in the HTMX GitHub repository.

Remember that HTMX is a flexible library, and its usage may vary depending on your specific project requirements. Feel free to ask more specific questions or seek guidance on particular aspects of HTMX as you explore it further.

✅ HTMX vs. React

HTMX and React are both JavaScript libraries/frameworks, but they serve different purposes and have distinct characteristics.

Here's a detailed comparison between the two:

Purpose and Use Cases

  • HTMX:

    • Server-Side Rendering (SSR): HTMX is designed to enhance traditional server-side rendering (SSR) web applications. It allows you to add dynamic behavior to your existing server-rendered HTML pages without completely overhauling your architecture.
    • Progressive Enhancement: HTMX focuses on progressive enhancement, which means you start with a basic HTML page and then progressively add interactivity and dynamic behavior as needed.
  • React:

    • Single-Page Applications (SPAs): React is often used to build single-page applications (SPAs) where most of the application logic is handled on the client side. It's especially popular for building complex, highly interactive web applications.
    • Virtual DOM: React uses a virtual DOM to efficiently update and render components, making it well-suited for applications with frequent UI updates.

Learning Curve:

  • HTMX:

    • HTMX has a relatively low learning curve, especially if you're already familiar with HTML, CSS, and traditional web development.
    • It doesn't require you to learn a new component-based architecture like React.
  • React:

    • React has a steeper learning curve, particularly if you're new to component-based UI development and concepts like JSX.
    • It may take some time to become proficient in React's ecosystem, including libraries like Redux for state management.


  • HTMX:

    • HTMX relies on the browser's built-in capabilities and server-side rendering, which can lead to good initial load performance.
    • It may be less performant for highly dynamic SPAs compared to React due to frequent server requests.
  • React:

    • React's virtual DOM and efficient updates can lead to excellent runtime performance for SPAs with complex UIs.
    • However, React apps may have a heavier initial load because they require downloading JavaScript bundles.

Data Flow and State Management:

  • HTMX:

    • HTMX doesn't provide built-in state management. It relies on the server for data.
    • You can use traditional server-side techniques for managing application state.
  • React:

    • React has a built-in state management system and can work with various state management libraries (e.g., Redux, Mobx) for more complex applications.
    • It offers a unidirectional data flow, making it easier to manage and update component state.

Ecosystem and Community:

  • HTMX:

    • HTMX has a smaller ecosystem and community compared to React.
    • There are fewer third-party libraries and tools available for HTMX.
  • React:

    • React has a large and active community with a vast ecosystem of third-party libraries, tools, and resources.
    • This strong community support makes it easier to find solutions to common problems and integrate with other technologies.


  • HTMX:

    • HTMX can be integrated into existing server-rendered applications with relative ease.
    • It can work with various server-side languages and frameworks.
  • React:

    • React often requires a more significant overhaul of your application architecture if you're transitioning from a non-SPA to an SPA model.
    • It's commonly used with Node.js on the server side for server rendering (Next.js, for example).

Project Type:

  • HTMX:

    • Suitable for projects where SEO and initial load performance are critical.
    • Great for enhancing traditional websites with small amounts of interactivity.
  • React:

    • Ideal for building complex, interactive SPAs or web applications where real-time updates and interactivity are central.

✅ In Summary

In summary, the choice between HTMX and React depends on your project requirements and familiarity with each technology. HTMX is well-suited for enhancing traditional server-rendered websites with progressive interactivity, while React is a robust choice for building modern SPAs with complex user interfaces.
