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
| Concept | Usage | Example |
|---|---|---|
| Touch targets | Minimum 48px for IoT controls | Class="mud-switch-large" |
| Status colors | Semantic feedback for tank/control states | Color.Success, Color.Warning, Color.Error |
| Elevation | Visual hierarchy in dashboard cards | Elevation="2" for cards, Elevation="4" for dialogs |
| Dense mode | Compact displays for small screens | Dense="true" on tables and lists |
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>
