Stuartf303 Vandaemon Frontend Design

Frontend Design Skill

VanDaemon uses MudBlazor for Material Design components with a touch-optimized, offline-first IoT dashboard. The design emphasizes real-time data visualization through SVG van diagrams with draggable overlays, high-contrast readability for use in varying lighting conditions, and immediate visual feedback for control operations.

Quick Start

MudBlazor Component Styling

@* Touch-optimized control card *@
<MudCard Class="pa-4 my-2" Elevation="2">
    <MudCardContent>
        <MudText Typo="Typo.h6">@Control.Name</MudText>
        <MudSwitch T="bool" 
                   @bind-Value="isOn"
                   Color="Color.Primary"
                   Class="mud-switch-large" />
    </MudCardContent>
</MudCard>

SVG Diagram Overlay

<div class="van-diagram-container" style="position: relative;">
    <img src="diagrams/@settings.VanDiagram" alt="Van Diagram" class="van-image" />
    @foreach (var overlay in overlayPositions)
    {
        <div class="overlay-item" 
             style="left: @(overlay.X)%; top: @(overlay.Y)%; position: absolute;">
            <MudChip Color="@GetStatusColor(overlay)" Size="Size.Small">
                @overlay.Label: @overlay.Value%
            </MudChip>
        </div>
    }
</div>

Key Concepts

Common Patterns

Real-Time Status Display

When: Displaying tank levels, control states, or sensor readings.

<MudProgressLinear Color="@GetTankColor(tank.CurrentLevel)" 
                   Value="@tank.CurrentLevel"
                   Class="my-2"
                   Rounded="true"
                   Size="Size.Large">
    <MudText Typo="Typo.body2">@tank.Name: @tank.CurrentLevel.ToString("F0")%</MudText>
</MudProgressLinear>

@code {
    private Color GetTankColor(double level) => level switch
    {
        < 15 => Color.Error,
        < 30 => Color.Warning,
        _ => Color.Success
    };
}

Connection Status Indicator

When: Showing SignalR connection state in the app bar.

<MudBadge Color="@(isConnected ? Color.Success : Color.Error)" 
          Dot="true" 
          Overlap="true"
          Class="mx-2">
    <MudIcon Icon="@Icons.Material.Filled.Wifi" />
</MudBadge>
