HTML element with hx-get
Frontend / Knowledge library
htmx
server-driven html updates through attributes
Why learn htmx?
Useful for progressively enhanced, server-rendered interfaces. Server responses, authentication, and request validation still need normal web security controls.
Where it came from
htmx extends HTML with attributes for issuing requests and swapping returned content into the page. It supports server-driven interaction without requiring a full client application framework.

Real World Example
Dynamic Inventory Stock Updates
Retail warehouse managers needing real-time visibility into stock levels without complex frontend state management.
The business problem
Traditional page reloads for stock checks are slow, while building a full JavaScript SPA to handle partial updates introduces significant maintenance overhead and complexity.
How this topic solves it
htmx allows the server to push HTML fragments directly to specific DOM elements, enabling reactive UI updates through standard HTML attributes without writing custom JavaScript.
- Identify the container element in the HTML that displays the current stock count.
- Add the hx-get attribute to a refresh button pointing to the server endpoint that returns the updated stock HTML fragment.
- Set the hx-target attribute to the ID of the stock display container.
- Configure the hx-swap attribute to replace the innerHTML of the target element with the new server response.
Shows how a user action triggers a server request and updates the DOM.
Intercepts event and issues AJAX
Processes request and returns HTML
Element updated via hx-swap
- User Interface → triggers event → htmx Library
- htmx Library → issues HTTP request → Server
- Server → returns HTML fragment → DOM Target
Implementation example
The button triggers a GET request to the server, which returns the new stock count as an HTML fragment, which is then injected into the div.
<button hx-get="/stock/check" hx-target="#stock-level" hx-swap="innerHTML">Refresh Stock</button>
<div id="stock-level">100</div>Expected business outcome
The inventory dashboard remains responsive and displays current data with minimal code, maintaining a clean separation between server-side logic and client-side presentation.
Limitations and checks
Because htmx relies on server-side HTML generation, high-frequency updates can increase server load; verify this by monitoring the frequency of requests and the size of the returned HTML fragments.
