## Quick Start

### 1. Add as submodule

```bash
git submodule add https://github.com/RaRdq/RR.Blazor.git
```

### 2. Configure your project

```xml

<Project Sdk="Microsoft.NET.Sdk.BlazorWebAssembly">
  
  
  <ItemGroup>
    <ProjectReference Include="..\RR.Blazor\RR.Blazor.csproj" />
  </ItemGroup>
  
  
  
  <Import Project="..\RR.Blazor\build\RR.Blazor.targets" />
</Project>
```

### 3. Register services

```csharp
// Program.cs
var builder = WebApplication.CreateBuilder(args);

// REQUIRED for Blazor Server: Enable static web assets
builder.WebHost.UseStaticWebAssets();

// Register RR.Blazor services (includes modal system, templates, etc.)
builder.Services.AddRRBlazor();
```

For Blazor WebAssembly projects:
```csharp
// Program.cs
builder.Services.AddRRBlazor();
```

### 3. Add CSS and JavaScript references

Choose the appropriate file based on your Blazor hosting model:

#### Blazor WebAssembly (WASM)
```html

<head>
    <link href="_content/RR.Blazor/css/main.css" rel="stylesheet" />
</head>
<body>
    <script type="module" src="_content/RR.Blazor/js/rr-blazor.js"></script>
</body>
```

#### Blazor Server
```html

<head>
    <link href="_content/RR.Blazor/css/main.css" rel="stylesheet" />
</head>
<body>
    <script type="module" src="_content/RR.Blazor/js/rr-blazor.js"></script>
</body>
```

#### Blazor Web (Interactive Server/WASM)
```razor

<head>
    <link href="_content/RR.Blazor/css/main.css" rel="stylesheet" />
</head>
<body>
    <script type="module" src="_content/RR.Blazor/js/rr-blazor.js"></script>
</body>
```

### 4. Use RAppShell (Zero Hustle)

```razor

<RAppShell>
    @Body
</RAppShell>
```

**That's it!** RAppShell includes theme provider, portal-based modal system (with ModalProvider), toast container, intelligent search system, and styles.

### Alternative: Manual Setup

```razor

@using RR.Blazor.Components
@using RR.Blazor.Enums
```

```razor

<RThemeProvider>
    <RToastContainer />
    <ModalProvider />
    @Body
</RThemeProvider>
```

## Usage Guide

### 🤖 AI Agent Integration
For AI agents (Claude, GPT-4, etc.), add a rule or manually refer to [`@RR.Blazor\_Documentation\RRAI.md`](_Documentation/RRAI.md) for comprehensive component documentation, patterns, and AI-optimized examples.

### Smart Components

```razor

<RDropdown Items="users" @bind-SelectedValue="selectedUser" />

<RForm Model="user" OnValidSubmit="SaveUser" />
```

### Data Tables & Chart Integration

**Zero-Config Tables with Built-in Chart Integration:**

```razor

<RTable Items="@salesData" 
        Title="Sales Report"
        ShowChartButton="true"
        ShowSearch="true" />

<RTableVirtualized Items="@largeDataset" 
                   Height="600px"
                   ShowChartButton="true"
                   ExportEnabled="true" />

<RChartGeneric Data="@tableRef.FilteredData" 
               Title="Dynamic Analytics" />
```

**Table-Chart Data Binding:**
- Tables automatically expose `FilteredData` property for chart binding
- Real-time chart updates as table data changes
- Built-in chart modal with one-click visualization
- Automatic chart type detection based on data structure

### Professional UI Components

```razor
<RCard Title="Dashboard" Elevation="4" Class="pa-6">
    <RButton Text="Save Changes" 
             Icon="save" 
             IconPosition="IconPosition.Start"
             OnClick="HandleSave" />
</RCard>

<RTable Items="@employees" />  @* Zero configuration - auto-generates all columns! *@
```

### Forms with Validation

```razor
<RForm Model="user" OnValidSubmit="SaveUser">
    <RTextInput @bind-value="user.Email" Type="email" Required />
    <RTextInput @bind-value="user.Password" Type="password" Required />
    <RButton Text="Register" Type="ButtonType.Submit" />
</RForm>
```

### Toast Notifications

```razor
@inject IToastService ToastService

<RButton Text="Show Success" 
         OnClick="@(() => ToastService.ShowSuccess("Operation completed!"))" />
```

### Responsive Images with Lazy Loading

```razor

<RImage Src="/api/products/123/image" 
        Alt="Product thumbnail"
        LazyLoading="true"
        ShowSkeleton="true" />

<RImage Src="/images/hero.jpg"
        Alt="Hero banner"
        Srcset="/images/hero-sm.jpg 640w, /images/hero-md.jpg 1024w, /images/hero-lg.jpg 1920w"
        Sizes="(max-width: 640px) 100vw, (max-width: 1024px) 50vw, 33vw"
        AspectRatio="16/9"
        ObjectFit="ObjectFit.Cover"
        Priority="true" />

<RImage Src="@user.AvatarUrl"
        Alt="@user.Name"
        Variant="ImageVariant.Circle"
        Width="64"
        Height="64"
        ErrorSrc="/images/default-avatar.png" />
```

### Modal System

RR.Blazor provides a unified modal system with 4 distinct usage patterns. All patterns use the same portal-based rendering, backdrop management, and z-index stacking.

#### **Case 1: Raw Content Components** (WITHOUT internal RModal)
Components without RModal wrapper - Provider auto-wraps them. Use `ShowRawAsync<T>()` for strongly-typed results.
```razor
// Component without internal RModal - gets wrapped automatically
var result = await ModalService.ShowRawAsync<UserData>(
    typeof(UserFormContent),
    parameters: new() { { "UserId", userId } },
    options: new() { Title = "Edit User", Size = SizeType.Large }
);
if (result.ResultType == ModalResult.Ok)
{
    var userData = result.Data; // Strongly typed!
}
```

#### **Case 2: Self-Contained Components** (WITH internal RModal)
Components with their own `<RModal>` wrapper - Provider renders directly without double-wrapping.
```razor
// Component has <RModal> inside - no double wrap
await ModalService.ShowAsync(new ModalOptions {
    ComponentType = typeof(SettingsModalWithWrapper),
    Parameters = new() { { "Settings", currentSettings } }
});
```

#### **Case 3: Direct RModal Usage** (@bind-Visible)
Standalone modals with two-way binding - integrates with JS modal system for portals/backdrops.
```razor
<RModal @bind-Visible="showModal"
        Title="My Modal"
        CloseOnBackdrop="true"
        Size="SizeType.Large">
    <ChildContent>
        Your content here
    </ChildContent>
    <FooterContent>
        <RButton @onclick="() => showModal = false">Close</RButton>
    </FooterContent>
</RModal>
```

#### **Case 4: Service-Based Utility Modals**
Quick confirmations and info dialogs via ModalService convenience methods.
```razor
// Confirmation dialog
bool confirmed = await ModalService.ShowConfirmationAsync(
    "Are you sure you want to delete?",
    "Delete Item",
    "Delete", "Cancel",
    VariantType.Error
);

// Info dialog
await ModalService.ShowInfoAsync(
    "Operation completed successfully",
    "Success"
);
```

#### Modal Features
- ✅ Unified portal-based rendering for all 4 cases
- ✅ Automatic z-index stacking for nested modals
- ✅ Individual backdrop per modal with proper click handling
- ✅ Escape key closes topmost modal only
- ✅ Parent closing cascades to child modals/dropdowns
- ✅ Strongly-typed results with `ShowRawAsync<T>()`
- ✅ Loading states, progress indicators, multi-step support
- ✅ Memory-safe cleanup with proper disposal

### Intelligent Search System

RAppShell includes a built-in, role-aware search system with collapsible interface:

```razor

<RAppShell SearchCollapsible="true">
    
    @Body
</RAppShell>
```

**Search Features:**
- **Universal Search**: Searches across all registered data providers
- **Role-Based Filtering**: Results filtered by user permissions
- **Lightning Fast**: Sub-2-second response times with intelligent caching
- **Collapsible Interface**: Expands on click, auto-collapses when empty
- **Smart Suggestions**: Contextual results with relevance scoring

**Search Provider Registration:**

```csharp
// Register custom search providers
public class MySearchProvider : ISearchProvider
{
    public string Name => "MyData";
    public int Priority => 10;
    
    public async Task<List<AppSearchResult>> SearchAsync(string query, CancellationToken cancellationToken = default)
    {
        // Your search implementation
        return await MyDataService.SearchAsync(query);
    }
}

// In your layout
@inject IAppSearchService AppSearchService

@code {
    protected override void OnInitialized()
    {
        AppSearchService.RegisterSearchProvider(new MySearchProvider());
    }
}
```
