The ui.dsl module provides a server-side HTML node DSL for Goja runtimes. It exports safe tag builders, document rendering, and internal-tool components such as tables, code blocks, badges, and tabs.

The module is available through both aliases when registered with uidsl.NewRegistrar():

const ui = require("ui.dsl");
// or
const ui = require("ui");

Go setup

factory, err := engine.NewBuilder().
    WithModules(uidsl.NewRegistrar()).
    Build()

For HTTP applications, pair it with pkg/gojahttp and modules/express:

host := gojahttp.NewHost(gojahttp.HostOptions{
    Renderer: uidsl.RenderAny,
})

Core API

ui.page({ title: "Title" }, ...children)
ui.fragment(...children)
ui.text(value)
ui.raw(html)
ui.render(value)

The module exports common HTML tag helpers such as div, span, h1, p, a, form, input, table, tr, td, script, style, and SVG helpers. Tag helpers accept an optional first attribute object followed by children:

ui.div({ class: "card" },
  ui.h2("Result"),
  ui.p("Safe text")
)

Safety model

Normal text and attribute values are escaped. ui.raw(html) intentionally bypasses escaping and should only be used with trusted HTML or CSS.

ui.p("<script>")      // renders escaped text
ui.raw("<strong>ok</strong>") // renders raw HTML

Tables

ui.table.fromRows("users", [
  { id: 1, name: "Ada", active: true },
  { id: 2, name: "Grace", active: false },
])

The richer table builder supports columns, filters, sorting, pagination, money/date/tags/badge cell kinds, links, and empty states. These components are designed for server-rendered internal tools and database browsers.

Inspection components

ui.codeBlock("sql", "select * from users")
ui.sql("select * from users")
ui.js("console.log('hello')")
ui.jsonBlock({ ok: true })
ui.badge("active", { tone: "success" })
ui.tabs("details", [
  { id: "summary", label: "Summary", content: ui.p("Overview") },
  { id: "raw", label: "Raw", content: ui.jsonBlock({ ok: true }) },
])

These helpers render static HTML/CSS and do not require client-side JavaScript for their basic behavior.
