eSeGeCe — Enterprise Communication Components for Delphi & .NET
FEATURED · sgcHTML

Your backend already speaks HTML

Build the whole web app in Pascal. Server-side HTML components render Bootstrap 5 markup, htmx keeps every click interactive, and WebSockets push live updates into the open page. No npm, no JavaScript build step.

Left: Object Pascal. Right: the page it serves, live in the browser. Same components in C++ Builder and C#.

sgcHTML

Server-side HTML components for Delphi, C++ Builder and .NET. Charts, grids, forms, dashboards and chat, rendered as Bootstrap 5 markup and kept live by htmx over WebSockets.

Engine, Server & Theming

TsgcHTMLEngine_Server serves the rendered pages, TsgcHTMX_Engine_Server dispatches htmx requests and pushes fragments, and PageBuilder, TemplateBootstrap, ThemeController and ThemeBuilder handle the document and light or dark themes.

View family →

Bootstrap 5.3 and htmx ship embedded, so there is no CDN call at runtime. Built-in UI text comes in 17 languages, and every component HTML, attribute, JavaScript and URL encodes its dynamic content by default.

REAL-TIME UI

The Server Renders. htmx Swaps. WebSockets Push.

There is no client-side state to keep in sync, because there is no client-side application. Your Pascal or C# code owns the page: it answers the first request with HTML, answers each interaction with a fragment, and pushes new fragments to every open browser the moment the data changes.

Browser sgcHTML server GET /dashboard 200 · full Bootstrap 5 page hx-post /orders/filter OnHTMXRequest → fragment, swapped in place WebSocket · BroadcastFragment(hx-swap-oob)
  1. Compose

    Build the page from TsgcHTMLComponent_* classes in Pascal or C#, or bind them to a dataset and let them render the rows.

  2. Serve

    TsgcHTMLEngine_Server answers the request from your own HTTP server with a complete Bootstrap 5 document and its embedded assets.

  3. Swap

    htmx sends the interaction back to OnHTMXRequest. Your handler returns only the fragment that changed, and htmx swaps it in place.

  4. Push

    BroadcastFragment sends an out-of-band fragment over the WebSocket to every connected browser. It is thread-safe, so a background timer can call it directly.

ONE COMPONENT, ONE WEBSITE

TsgcHTMLComponent_Site

Header, navigation menu, content area and footer, wrapped in a swappable layout template. Set the layout, theme and brand, add the menu and the content, then read the HTML property and serve the finished page.

sgcHTML requires sgcWebSockets Professional or Enterprise, and it is included in the All-Access bundle.

GENERATE THE API LAYER

sgcOpenAPI Writes the Back End Your UI Calls

Your sgcHTML pages need data, and that data usually comes from an API. sgcOpenAPI is one bundled product for Delphi and C++ Builder: an OpenAPI 3.x parser, a native Pascal SDK generator, an OpenAPI server component, and a library of pre-built cloud SDKs you can use straight away.

OpenAPI 3.x parser

Read any OpenAPI 3.x document, in JSON or YAML, into a strongly-typed object model you can walk from code.

The parser →

Pascal SDK generator

Turn that spec into a native Delphi or C++ Builder client, with typed request and response classes, ready to compile.

Generator features →

OpenAPI server component

Publish your own endpoints as a live openapi.json or openapi.yaml, build endpoints from a spec, and validate requests and responses against it.

The server →

Pre-built cloud SDKs

Amazon AWS 280+, Microsoft Azure 650+, Google Cloud 250+ and Microsoft Graph 15+ services, already generated for you.

Browse the APIs →
1,195+ Pre-built SDKs AWS, Azure, Google Cloud and Microsoft Graph, on a single Single, Team or Site licence. Delphi 7 to RAD Studio 13.
