HTMX: minimal response

Available since: 3.1.3

Forces the current request to return the minimal HTMX response instead of a full HTML page, by setting the "_wrapper_format" query parameter to "drupal_htmx".

Affects only the current request

This action adds the _wrapper_format=drupal_htmx query parameter to the current request, so only that request returns the minimal (main-content-only) response. To mark a route so that every request to it returns the minimal response, use the HTMX: mark route action instead. The two approaches act at different stages of the request lifecycle and are not interchangeable — see Building HTMX-powered interfaces with ECA.
