HTMX Fragment & Router
TsgcHTMX_Fragment / TsgcHTMX_Router — build out-of-band htmx swap payloads for targeted DOM updates and route URL patterns to Delphi handler procedures.
TsgcHTMX_Fragment / TsgcHTMX_Router — build out-of-band htmx swap payloads for targeted DOM updates and route URL patterns to Delphi handler procedures.
TsgcHTMX_Fragment constructs the correctly formed out-of-band htmx swap string for a given DOM element id and swap strategy. TsgcHTMX_Router dispatches incoming HTTP requests to registered Delphi handler methods, eliminating manual URL parsing.
TsgcHTMX_Fragment, TsgcHTMX_Router
OOB swaps & request routing
Delphi, C++ Builder, .NET
Use TsgcHTMX_Fragment to construct an out-of-band htmx swap string targeting a specific DOM element id. Use TsgcHTMX_Router to dispatch incoming HTTP requests to registered handler methods without writing if/else chains.

id of the DOM element to replace; corresponds to htmx's hx-swap-oob target.
htmx swap strategy: innerHTML, outerHTML, beforebegin, afterend, etc.
The new HTML to inject into the target; can be a simple string or the output of any sgcHTML component.
Read-only; returns the fully formed OOB swap string ready to pass to BroadcastFragment or return as an HTTP response body.
Registers a URL pattern and HTTP method combination with a Delphi handler procedure or method.
Checks the incoming request against all registered routes and calls the matching handler; returns False if no route matched.
