t-sui Framework

t-sui is a TypeScript server-rendered UI framework.

• UI is generated as Node objects that compile to JavaScript strings (document.createElement() calls).
• Browser receives raw JS — no HTML templates, no JSON intermediate.
• Interactions call server actions via WebSocket, responses are JS strings for DOM mutations.

Feature Snapshot

• Server-rendered pages with PascalCase element constructors (ui.Div, ui.Span, ui.Button, etc.)
• Five DOM swap strategies: ToJS, ToJSReplace, ToJSAppend, ToJSPrepend, ToJSInner
• Server actions with data payloads and Collect-based field collection
• Multi-action ResponseBuilder for complex updates
• Real-time push via ctx.Push() and broadcast via app.Broadcast()
• SPA navigation via __nav(url) with layout content injection
• Route + query param APIs for dynamic pages
• FormBuilder with 20 field types and Collect-based submission
• DataTable with search, sort, pagination, column filters, export
• Collate data panel with filter/sort/search
• Dark mode with ThemeSwitcher, Tailwind CSS via CDN
• Node.js and Bun runtime support

Quick Start

import ui from "./ui";
import { MakeApp, type Context } from "./ui.server";

const app = MakeApp("en");

app.Page("/", "Home", function (_ctx: Context) {
    return ui.Div("p-6").Render(ui.Div("text-2xl").Text("Hello"));
});

app.Listen(1423);

Current API Notes

• Use PascalCase element constructors: ui.Div, ui.Span, ui.Button, ui.P, etc.
• app.Page handler returns Node (not string).
• app.Action handler returns string (JS code).
• Actions are objects: { Name, Data?, Collect? } or ui.JS("code") for inline JS.
• ui.Target() returns a random string ID, not an object.
• Route params use colon syntax: /users/:id with ctx.PathParams["id"].
• No ctx.Patch, ctx.Submit, ctx.Click, ctx.Call — use OnClick/OnSubmit with action objects.
• No lowercase HTML builders — all constructors are PascalCase.
