🌟 Overview

NeoUI for Blazor brings the beautiful design system of shadcn/ui to Blazor applications. This library provides zero-config, plug-and-play UI components with full shadcn/ui compatibility, featuring pre-built CSS, styled components, and headless primitives that work across all Blazor hosting models (Server, WebAssembly, and Hybrid).

No Tailwind CSS setup required - just install the NuGet package and start building!

✨ What's New in v4

🎨 Theme v2 — The Most Sophisticated Blazor Theming System

v4 brings NeoUI in full parity with shadcn/ui's April 2026 customisation model — and surpasses it with the most comprehensive shadcn-inspired theming system available for Blazor.

Style Variant System — 3-Layer CSS Merge Pipeline

Every major component now participates in a 3-layer CSS merge that faithfully renders shadcn/ui style variants while preserving the Blazor developer experience:

Layer 1: Base component classes  (sensible, backward-compatible defaults)
    ↓
Layer 2: StyleVariant overrides  (per-variant Tailwind classes via StyleVariant.GetClasses("Component.Key"))
    ↓
Layer 3: User Class prop          (always wins — merged via tailwind-merge)

50+ components fully wired — Button, Input, Card, Dialog, Sheet, Drawer, Tabs, Select, Combobox, DropdownMenu, ContextMenu, Menubar, Calendar, Command, Sidebar, TreeView, Toast, Tooltip, RadioGroup, Slider, RangeSlider, Switch, Toggle, ToggleGroup, Progress, Avatar, Badge, Alert, DataGrid, DataView, and more.

7 Named Style Variants

Variant	Character	--radius
Default	Backward-compatible — no visual change	unchanged
Vega	Professional, balanced	0.625rem
Nova	Compact, dashboard/admin	0.375rem
Maia	Spacious, consumer-friendly	1rem
Lyra	Sharp/boxy, developer tooling	0rem
Mira	Ultra-dense, data-heavy	0.25rem
Luma	Glassmorphism, modern SaaS	0.75rem

Luma goes furthest — pill-shaped containers, frosted inputs, stronger overlay blur, per-component shadow tuning — matching shadcn's Luma style exactly.

Full Theme Dimension Expansion

Dimension	Options
Style Variant	Default, Vega, Nova, Maia, Lyra, Mira, Luma
Base Color	Zinc, Slate, Gray, Neutral, Stone + Mist, Mauve, Taupe, Olive (new)
Primary Color	17 colors
Radius Preset	None, Small, Medium, Large
Font Preset	System, Inter, Geist, CalSans, DmSans, PlusJakarta
Menu Color	Default, Inverted, DefaultTranslucent (glassmorphism), InvertedTranslucent
Menu Accent	Subtle, Bold
Dark Mode	Light / Dark

ThemeSwitcher Redesign

The ThemeSwitcher trigger now shows a two-tone color swatch reflecting the current base + primary color pair. Add ShowStyles="true" to expose the full visual picker with animated tabs:

@* Minimal — colors + dark mode *@
<ThemeSwitcher />

@* Full picker — all 8 theme dimensions with visual previews *@
<ThemeSwitcher ShowStyles="true" />

AppProvider — Required Setup

Wrap your layout with <AppProvider> to enable StyleVariant propagation and automatic theme initialization:

@* MainLayout.razor *@
<AppProvider>
    @Body
    @* Portal hosts must be inside AppProvider *@
    <ToastViewport />
    <DialogHost />
</AppProvider>

Backward Compatible

StyleVariant.Default preserves all pre-v4 radius ratios — existing apps see zero visual change after upgrading. Theme v2 is entirely opt-in.

🚀 Getting Started

📦 Installation

Install NeoUI packages from NuGet:

# Styled components with shadcn/ui design
dotnet add package NeoUI.Blazor

# (Optional) Headless primitives for custom styling
dotnet add package NeoUI.Blazor.Primitives

# Icon libraries (choose one or more)
dotnet add package NeoUI.Icons.Lucide      # 1,640 icons - stroke-based, consistent
dotnet add package NeoUI.Icons.Heroicons   # 1,288 icons - 4 variants (outline, solid, mini, micro)
dotnet add package NeoUI.Icons.Feather     # 286 icons - minimalist, stroke-based

Quick Start

1. Add to your _Imports.razor:

@using NeoUI.Blazor

Optional icon packages — add whichever you need:

@using NeoUI.Icons.Lucide      @* 1,640+ icons *@
@using NeoUI.Icons.Heroicons   @* 1,288 icons across 4 variants *@
@using NeoUI.Icons.Feather     @* 286 minimalist icons *@

2. Wrap your layout with AppProvider:

   AppProvider initializes ThemeService and propagates the active StyleVariant to all components. Portal hosts must be placed inside it:

@inherits LayoutComponentBase

<AppProvider>
    <!-- Your layout content -->
    @Body

    <!-- Portal hosts must be inside AppProvider -->
    <ToastViewport />
    <DialogHost />
</AppProvider>

@* For overlay components to work correctly *@
<ContainerPortalHost />
<OverlayPortalHost />

3. Add CSS and scripts to your App.razor:

   NeoUI Components come with pre-built CSS and a theme script — no Tailwind setup required!

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <base href="/" />
    <!-- Your theme CSS variables -->
    <link rel="stylesheet" href="styles/theme.css" />
    <!-- Pre-built NeoUI styles -->
    <link href="@Assets["_content/NeoUI.Blazor/components.css"]" rel="stylesheet" />
    <!-- Theme script: reads localStorage and applies classes before Blazor loads (prevents FOUC) -->
    <script src="@Assets["_content/NeoUI.Blazor/js/theme.js"]"></script>
    <HeadOutlet @rendermode="InteractiveAuto" />
</head>
<body>
    <Routes @rendermode="InteractiveAuto" />
    <script src="@Assets["_framework/blazor.web.js"]"></script>
</body>
</html>

4. Start using components:

<Button Variant="ButtonVariant.Default">Click me</Button>

<Dialog>
    <DialogTrigger AsChild>
        <Button>Open Dialog</Button>
    </DialogTrigger>
    <DialogContent>
        <DialogHeader>
            <DialogTitle>Welcome to NeoUI</DialogTitle>
            <DialogDescription>
                Beautiful Blazor components inspired by shadcn/ui
            </DialogDescription>
        </DialogHeader>
        <DialogFooter>
            <DialogClose AsChild>
                <Button Variant="ButtonVariant.Outline">Close</Button>
            </DialogClose>
        </DialogFooter>
    </DialogContent>
</Dialog>

AsChild Pattern: Use AsChild on trigger components to use your own styled elements (like Button) instead of the default button. This is the industry-standard pattern from Radix UI/shadcn/ui.

Localization

NeoUI ships a built-in ILocalizer abstraction — a thin interface that decouples your app from any specific i18n framework.

Default behaviour — DefaultLocalizer is registered automatically by AddNeoUIComponents(). It returns the built-in English strings for every UI key (button labels, ARIA attributes, empty-state messages, etc.). No configuration required.

Customizing strings — implement ILocalizer and register it before calling AddNeoUIComponents():

// Option A — custom DefaultLocalizer keys (simplest)
builder.Services.AddSingleton<ILocalizer>(sp =>
    new DefaultLocalizer(keys => {
        keys["Dialog.Close"] = "Schließen";
    }));
builder.Services.AddNeoUIComponents();

// Option B — full IStringLocalizer<T> integration
builder.Services.AddScoped<ILocalizer, StringLocalizerAdapter<MyResources>>();
builder.Services.AddNeoUIComponents();

Both options work for Blazor Server, WebAssembly, and Auto mode.

🏗️ Architecture

NeoUI uses a two-layer architecture with modern .NET 10 features and Auto rendering mode:

Project Structure

• NeoUI.Blazor.Primitives - Headless components (runs on both Server and WebAssembly)
• NeoUI.Blazor - Pre-styled components (runs on both Server and WebAssembly)
• NeoUI.Demo.Shared - Shared pages, components, services, and static assets (.NET 10)
• NeoUI.Demo.Server - Server-only hosting (.NET 10)
• NeoUI.Demo.Wasm - WebAssembly-only hosting (.NET 10)
• NeoUI.Demo.Auto - Auto mode (Server+WASM) hosting (.NET 10)
• NeoUI.Demo.Auto.Client - WASM satellite for Auto mode (.NET 10)

Rendering Mode

All components support .NET 10's Auto rendering mode, which automatically switches between Server and WebAssembly based on availability:

<!-- App.razor -->
<HeadOutlet @rendermode="InteractiveAuto" />
<Routes @rendermode="InteractiveAuto" />

This provides:

• Fast initial load (Server-side rendering)
• Rich interactivity (WebAssembly after download)
• Seamless transition between modes
• Optimal performance for all scenarios

Styled Components Layer (NeoUI.Blazor)

• Pre-styled components matching shadcn/ui design system
• Pre-built CSS included - no Tailwind configuration needed
• Built on top of primitives for consistency
• Ready to use out of the box
• Full theme support via CSS variables

Primitives Layer (NeoUI.Blazor.Primitives)

• Headless, unstyled components
• Complete accessibility implementation
• Keyboard navigation and ARIA support
• Maximum flexibility for custom styling

Key Principles

• Feature-based organization - Each component in its own folder with all related files
• Code-behind pattern - Clean separation of markup (.razor) and logic (.razor.cs)
• CSS Variables theming - Runtime theme switching with light/dark mode support
• Accessibility first - WCAG 2.1 AA compliance with comprehensive keyboard navigation
• Composition over inheritance - Components designed to be composed together
• Progressive enhancement - Works without JavaScript where possible

🎨 Theming

NeoUI is 100% compatible with shadcn/ui themes, making it easy to customize your application's appearance.

Using Themes from shadcn/ui and tweakcn

You can use any theme from:

• shadcn/ui themes - Official shadcn/ui theme gallery
• tweakcn.com - Advanced theme customization tool with live preview

Simply copy the CSS variables from these tools and paste them into your wwwroot/styles/theme.css file.

Customizing Your Theme

1. Create wwwroot/styles/theme.css in your Blazor project

2. Add your theme variables inside the :root (light mode) and .dark (dark mode) selectors:

@layer base {
  :root {
    --background: oklch(1 0 0);
    --foreground: oklch(0.1450 0 0);
    --primary: oklch(0.2050 0 0);
    --primary-foreground: oklch(0.9850 0 0);
    /* ... other variables */
  }

  .dark {
    --background: oklch(0.1450 0 0);
    --foreground: oklch(0.9850 0 0);
    --primary: oklch(0.9220 0 0);
    --primary-foreground: oklch(0.2050 0 0);
    /* ... other variables */
  }
}

3. Reference it in your App.razor before the NeoUI CSS:

<link rel="stylesheet" href="styles/theme.css" />
<link href="@Assets["_content/NeoUI.Blazor/components.css"]" rel="stylesheet" />

That's it! NeoUI will automatically use your theme variables.

Available Theme Variables

NeoUI supports all standard shadcn/ui CSS variables:

• Colors: --background, --foreground, --primary, --secondary, --accent, --destructive, --muted, etc.
• Typography: --font-sans, --font-serif, --font-mono
• Layout: --radius (border radius), --shadow-* (shadows)
• Charts: --chart-1 through --chart-5
• Sidebar: --sidebar, --sidebar-primary, --sidebar-accent, etc.

Dark Mode

NeoUI automatically supports dark mode by applying the .dark class to the <html> element. All components will automatically switch to dark mode colors when this class is present.

🎨 Theme v2 — Dynamic Multi-Dimensional Theming

NeoUI includes a complete runtime theme system with 8 independently-configurable dimensions:

ThemeService — inject anywhere to read or change the theme programmatically:

// Apply a built-in preset
await ThemeService.ApplyPresetAsync(ThemePreset.Luma);

// Or set individual dimensions
await ThemeService.SetStyleVariantAsync(StyleVariant.Nova);
await ThemeService.SetBaseColorAsync(BaseColor.Mauve);
await ThemeService.SetMenuColorAsync(MenuColor.DefaultTranslucent);

ThemeSwitcher component — expose the full visual picker to your users:

@* Colors + dark mode only (default) *@
<ThemeSwitcher />

@* Full picker with style, radius, font, and menu controls *@
<ThemeSwitcher ShowStyles="true" />

Setup: theme.js (included automatically) applies saved theme classes before Blazor loads — no FOUC. Wrap your layout in <AppProvider> so components receive the active StyleVariant cascade. See THEMING.md for the full guide.

💅 Styling

NeoUI.Blazor (Pre-styled)

No Tailwind CSS setup required! NeoUI Components include pre-built, production-ready CSS that ships with the NuGet package.

Add the following to your App.razor:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <base href="/" />

    <!-- 1. Your custom theme (defines CSS variables) -->
    <link rel="stylesheet" href="styles/theme.css" />

    <!-- 2. Pre-built NeoUI styles -->
    <link href="@Assets["_content/NeoUI.Blazor/components.css"]" rel="stylesheet" />

    <!-- 3. Theme script: reads localStorage and applies classes before Blazor loads (prevents FOUC) -->
    <script src="@Assets["_content/NeoUI.Blazor/js/theme.js"]"></script>

    <HeadOutlet @rendermode="InteractiveAuto" />
</head>
<body>
    <Routes @rendermode="InteractiveAuto" />
    <script src="@Assets["_framework/blazor.web.js"]"></script>
</body>
</html>

Important: Load your theme CSS before components.css so the CSS variables are defined when NeoUI references them.

Note: The pre-built CSS is already minified and optimized. You don't need to install Tailwind CSS, configure build processes, or set up any additional tooling.

NeoUI.Blazor.Primitives (Headless)

Primitives are completely headless - they provide behavior and accessibility without any styling. You have complete freedom to style them however you want:

Option 1: Tailwind CSS (requires your own Tailwind setup)

<NeoUI.Blazor.Primitives.Accordion.Accordion class="space-y-4">
    <NeoUI.Blazor.Primitives.Accordion.AccordionItem class="border rounded-lg">
        <!-- Your custom Tailwind classes -->
    </NeoUI.Blazor.Primitives.Accordion.AccordionItem>
</NeoUI.Blazor.Primitives.Accordion.Accordion>

Option 2: CSS Modules / Vanilla CSS

<NeoUI.Blazor.Primitives.Accordion.Accordion class="my-accordion">
    <!-- Style with your own CSS -->
</NeoUI.Blazor.Primitives.Accordion.Accordion>

Option 3: Inline Styles

<NeoUI.Blazor.Primitives.Accordion.Accordion style="margin: 1rem;">
    <!-- Direct inline styling -->
</NeoUI.Blazor.Primitives.Accordion.Accordion>

Primitives give you complete control over styling while handling all the complex behavior, accessibility, and keyboard navigation for you. Unlike NeoUI.Blazor, primitives don't include any CSS - you bring your own styling approach.

• ScreenTransition - Screen-level animated transition wrapper for shell-based navigation. Supports Tab (fade), Push (slide from right), and Pop (slide from left) directions. Pair with Tabs for tab-switch fades and a push/pop navigation stack.

📱 Mobile

Five dedicated mobile-first components for .NET MAUI Blazor Hybrid, PWA, and mobile-first web apps. All live in NeoUI.Blazor — no separate package or @using required.

• AppBar - Mobile-style top application bar with centered title, optional back-chevron (OnBack), transparent hero-overlay mode, and a RightContent slot
• BottomNav + BottomNavItem - Persistent bottom tab bar (iOS/Android/MAUI style). Supports 2–5 icon+label items, per-item notification badge, Fixed mode toggle for MAUI Hybrid containers, and safe-area inset padding
• NotificationBadge - Wraps any element and overlays a count badge (numeric, dot mode, three colour variants, max-count truncation with N+)
• QuantityStepper - Circular +/− buttons for quantity input. DestructiveAtMin swaps the minus button for a trash icon at the minimum value (cart UX)
• SectionHeader - Title row with optional "view all" chevron and separator line; eliminates repetitive header boilerplate in content-heavy screens

MAUI Hybrid note: BottomNav defaults to Fixed="true" (viewport-fixed) but can be set to Fixed="false" for in-flow layout inside a BlazorWebView container. Safe-area padding is applied via env(safe-area-inset-bottom) for iOS home indicator clearance.
