Quoted from htmx.org:
htmx gives you access to
AJAX, CSS Transitions, WebSockets and Server Sent Events directly in
HTML, using attributes, so you can build modern user interfaces with the
simplicity and power of hypertext
The idea behind htmx is to allow adding attributes to any HTML
element that cause an HTTP request. The HTTP response is typically a
(short) HTML fragment that extends or replaces an element on the page.
This allows us to program a most functionality interactive seen in
modern web applications using the powerful SWI-Prolog HTML generation
framework rather than having to write a JSON backend and accompanying
JavaScript frontend that runs in the browser.
Below is a minimal, yet fully functional application
:- use_module(library(http/http_server)).
:- use_module(library(http/htmx)).
:- use_module(library(main)).
:- initialization(main, main).
main(_Argv) :-
http_server([port(8080)]),
thread_get_message(quit).
http:location(htmx, root(htmx), []).
:- http_handler(root(.), home, []).
home(_Request) :-
reply_html_page(
[ title('HTMX demo'),
script(src('https://unpkg.com/htmx.org'), [])
],
[ button([ 'hx-post'('/htmx/clicked'),
'hx-swap'('outerHTML')
],
'Click me')
]).
:- http_handler(htmx(clicked), reply_htmx(\clicked), []).
clicked -->
html('Thanks for clicking me!').
HTMX requires no dedicated support from the server. This library
provides reply_htmx/1,2 to
reply with a single HTML element rather than an entire page. Future
versions of this library may provide some additional utility predicates.
- [det]reply_htmx(+HTML)
- [det]reply_htmx(+HTML,
+Request)
- Reply a plain HTML element as opposed to a complete HTML
page as created using reply_html_page/2,3.
While reply_htmx/1 is to be
used in a normal HTTP handler (route), reply_htmx/2
may be registered directly in the http_handler/3
declaration to deal with simple cases where we do not need the Request
data.
- [det]htmx_oob(++Target,
:HTML)
// - Emit an htmx out-of-band element. HTML is used to swap the
content of the DOM element with id Target.
