In action

@* Button with loading and toast *@
<SgButton Variant="SgButtonVariant.Primary" 
          IsLoading="@_saving"
          ProgressType="SgButtonProgressType.Ring"
          OnClick="Save">Save</SgButton>

<SgButton Variant="SgButtonVariant.Danger" 
          Type="SgButtonType.Link"
          Href="https://example.com">Delete</SgButton>

@inject SgToastService Toast

<button @onclick="() => Toast.Success('Done!')">Notify me</button>

@* Data grid with sorting, filtering, paging *@
<SgDataGrid TItem="Employee" Items="@employees"
            ShowSearch="true" PageSize="20">
    <SgDataGridColumn TItem="Employee" Title="Name" Value="@(e => e.Name)" Sortable="true" />
    <SgDataGridColumn TItem="Employee" Title="Department" Value="@(e => e.Dept)" Filterable="true" />
    <SgDataGridColumn TItem="Employee" Title="Salary" Value="@(e => e.Salary)" Format="C0" />
</SgDataGrid>

@* Confirm dialog *@
@inject SgConfirmService Confirm

@if (await Confirm.ConfirmAsync("Delete this record?", variant: SgAlertVariant.Danger))
{
    // user confirmed
}

@* Theming — light/dark toggle, 43 built-in themes *@
<SgThemeSwitcher />

43 built-in themes included: Natura UI, Solaris, Royal, Graphite, Forest, Neon, Glass, Chrono, Calyx, Apex, Zen, Neo, Oasis, Flux, Prism, Cosmos, Fractalis, Wave, Aurea, Sylvan, Medici, Aether, Clarity, Element, Radius, Muse, Forge, Gordian, Inclus, Reader, Signature, Cantus, Aether, Biofilia, Calyx, Cantus, Chrono, Circadian, Clarity, Clarity Clinical, Element, Ergo, Fractalis, Gordian, Inclus, Lumina, Muse, Oasis, Prism, Reader, Signature, Sylvan, Veiled, Wave, Window. Switch via SgThemeService.SetThemeAsync("theme-id"). Themes are JSON-defined (see docs/MIGRATION-2.0.md) and the runtime swaps a single <link> element — no per-click CSS push, browser cache does the work.

Build & test

dotnet restore
dotnet build -c Release
dotnet test
dotnet run --project SuperUI.Demo

Requires .NET 10 SDK. Tests use bUnit + xUnit.

To regenerate the per-theme static CSS files (after adding a JSON theme or changing SgThemeGenerator):

dotnet run --project tools/ThemeCssExporter/ThemeCssExporter.csproj -- "SuperUI/wwwroot/themes/css"

What's new in 2.0

  • JSON-defined themes (43 in alpha.1) — every theme is a JSON file in Themes/json/, validated against Themes/schemas/theme.schema.json. Adding a new theme no longer requires recompiling SuperUI.
  • New token layers — motion, state, elevation, a11y — published as _content/SuperUI/themes/sg-tokens-{motion,state,elevation,a11y}.css and bundled together by sg-theme-bundle.css.
  • color-mix() everywhere — 302 rgba() calls in superui-components.css are now color-mix(in srgb, ...) so tints track the active theme.
  • Link-swap runtime — the theme switcher now mutates a single <link rel="stylesheet"> in <head> instead of regenerating and re-injecting a 15-33 KB CSS string. Pre-built .css files ship with Cache-Control: max-age=31536000, immutable.
  • Debounced, batched, idempotent SgThemeService — 150 ms debounce, single applyThemeState({...}) JS round-trip, race-safe DisposeAsync, single matchMedia subscription that only mounts while the user is in auto mode.
  • SgThemeGenerator.GenerateFullThemeCss(IThemeDefinition) is now public — used by the build-time exporter and by anyone who needs to ship a pre-built CSS for a custom theme.
