When to Use

Use this skill whenever you need to:

• Build or modify Property Inspector UIs using sdpi-components
• Select appropriate components for different input types
• Implement data sources for dynamic content (selects, checkboxes, radios)
• Use Stream Deck Client API for plugin communication
• Handle settings persistence (action-specific or global)
• Debug Property Inspector issues related to sdpi-components
• Review Property Inspector code for best practices with sdpi-components

---

High‑Level Concepts

Before using sdpi-components, keep these core concepts in mind:

• sdpi-components

  • The official UI library for Stream Deck Property Inspectors.
  • Built with Lit.js and compiled to standard web components.
  • Provides consistent, accessible UI components that handle settings persistence automatically.
  • No build setup required — just include a single JavaScript file.

• Component structure

  • All components are prefixed with sdpi- (e.g., <sdpi-textfield>, <sdpi-checkbox>).
  • Components are typically wrapped in <sdpi-item> with a label attribute for consistent layout.
  • Components support the setting attribute to bind to settings paths (supports nested paths like foo.bar.prop).

• Settings persistence

  • Components automatically persist values to action-specific settings via the setting attribute.
  • Use the global attribute to persist to global settings (shared across all action instances).
  • Settings are automatically synced between Property Inspector and plugin.

• Communication

  • Components handle basic settings communication automatically.
  • Use SDPIComponents.streamDeckClient for advanced communication patterns.
  • Supports bidirectional communication: Property Inspector ↔ Plugin.

• Data sources

  • Some components (<sdpi-select>, <sdpi-checkbox-list>, <sdpi-radio>) support dynamic data sources.
  • Data sources fetch items from the plugin at runtime.
  • Supports hot-reload for real-time updates.

---

Prerequisites Checklist

Before using sdpi-components, verify all of the following:

1. Property Inspector setup

   • You have a Property Inspector HTML file in your plugin's ui/ directory.
   • The PropertyInspectorPath is configured in manifest.json (action or plugin level).

2. Library inclusion

   • Decide whether to use local (recommended) or remote (development) reference.
   • If using locally, download sdpi-components.js from releases.
   • Place sdpi-components.js in the ui/ directory alongside your HTML file.

3. Technical decisions

   • Determine which components you need for your settings UI.
   • Plan your settings data structure (what properties need to be configured).
   • Consider whether you need data sources for dynamic content.

Repository & File Structure

Property Inspector files using sdpi-components should be organized as follows:

my-streamdeck-plugin/
  *.sdPlugin/
    ├── bin/
    ├── imgs/
    ├── ui/                    # Property Inspector files
    │   ├── my-action.html
    │   └── sdpi-components.js  # Local library (recommended)
    └── manifest.json
  src/
    ├── actions/
    └── plugin.ts

The ui/ directory contains all Property Inspector HTML files and the sdpi-components.js library.

---

Step‑by‑Step: Getting Started with sdpi-components

Follow these steps to use sdpi-components in your Property Inspector:

1. Include the library

Local (recommended for distribution):

1. Download sdpi-components.js from the releases page.
2. Place it in your ui/ directory.
3. Reference it in your HTML:

<script src="sdpi-components.js"></script>

Remote (development/prototyping only):

<script src="https://sdpi-components.dev/releases/v4/sdpi-components.js"></script>

⚠️ Important: Always use local references when distributing your plugin to ensure it works offline and provides a consistent experience.

2. Basic HTML structure

Create your Property Inspector HTML file:

<!doctype html>
<html>
<head lang="en">
    <meta charset="utf-8" />
    <script src="sdpi-components.js"></script>
</head>
<body>
    <sdpi-item label="Name">
        <sdpi-textfield setting="name" placeholder="Enter name"></sdpi-textfield>
    </sdpi-item>
    
    <sdpi-item label="Enabled">
        <sdpi-checkbox setting="enabled"></sdpi-checkbox>
    </sdpi-item>
</body>
</html>

3. Configure components with settings

Use the setting attribute to bind components to your settings:

<sdpi-item label="Favorite Color">
    <sdpi-color setting="favColor"></sdpi-color>
</sdpi-item>

<sdpi-item label="Timeout (seconds)">
    <sdpi-range setting="timeout" min="1" max="60" step="1" showlabels></sdpi-range>
</sdpi-item>

4. Use global settings (optional)

To persist settings globally (shared across all action instances):

<sdpi-item label="API Key">
    <sdpi-textfield setting="apiKey" global></sdpi-textfield>
</sdpi-item>

5. Access Stream Deck Client (optional)

For advanced communication patterns:

<script>
    const { streamDeckClient } = SDPIComponents;
    
    // Get current settings
    streamDeckClient.getSettings().then(payload => {
        console.log('Current settings:', payload.settings);
    });
    
    // Listen for settings updates
    streamDeckClient.didReceiveSettings.subscribe(ev => {
        console.log('Settings updated:', ev.payload.settings);
    });
    
    // Set settings programmatically
    streamDeckClient.setSettings({
        name: "John Doe",
        enabled: true
    });
</script>

Data Sources

Data sources allow components to dynamically populate their options from the plugin at runtime.

Supported Components

Data sources are supported in:

• <sdpi-select>
• <sdpi-checkbox-list>
• <sdpi-radio>

Property Inspector Setup

HTML:

<sdpi-item label="Device">
    <sdpi-select
        setting="device"
        datasource="getDevices"
        loading="Fetching devices..."
        hot-reload>
    </sdpi-select>
</sdpi-item>

Configuration attributes:

• datasource (string): Event name that will be sent to the plugin
• loading (string): Optional text shown while loading
• hot-reload (boolean): Monitor sendToPropertyInspector for real-time updates

Manual refresh:

const selectElement = document.querySelector('[setting="device"]');
selectElement.refresh(); // Manually refresh the data source

Plugin Implementation

When a component with a datasource is initialized, the plugin receives a sendToPlugin event:

Request payload:

{
    "action": "com.example.myaction",
    "event": "sendToPlugin",
    "context": "unique-context-id",
    "payload": {
        "event": "getDevices",
        "isRefresh": undefined | true
    }
}

Plugin response (via sendToPropertyInspector):

{
    "action": "com.example.myaction",
    "event": "sendToPropertyInspector",
    "context": "unique-context-id",
    "payload": {
        "event": "getDevices",
        "items": [
            {
                "label": "Device Group",
                "children": [
                    {
                        "label": "Device 1",
                        "value": "device1"
                    },
                    {
                        "label": "Device 2",
                        "value": "device2"
                    }
                ]
            },
            {
                "label": "Device 3",
                "value": "device3"
            }
        ]
    }
}

TypeScript type definitions:

type DataSourcePayload = {
    event: string;
    items: DataSourceResult;
};

type DataSourceResult = DataSourceResultItem[];

type DataSourceResultItem = Item | ItemGroup;

type Item = {
    disabled?: boolean;
    label?: string;
    value: string;
};

type ItemGroup = {
    label?: string;
    children: Item[];
};

Example plugin implementation (Node.js/TypeScript):

import streamDeck, { action, type SendToPluginEvent } from "@elgato/streamdeck";

@action({ UUID: "com.example.myaction" })
class MyAction {
    override onSendToPlugin(ev: SendToPluginEvent): void {
        if (ev.payload.event === "getDevices") {
            // Fetch devices from your source
            const devices = [
                { label: "Device 1", value: "device1" },
                { label: "Device 2", value: "device2" }
            ];
            
            // Send response to Property Inspector
            streamDeck.actions.sendToPropertyInspector(ev.context, {
                event: "getDevices",
                items: devices
            });
        }
    }
}

Localization

Manifest Localization

Stream Deck supports localization via JSON files in your plugin directory:

File structure:

*.sdPlugin/
  ├── manifest.json
  ├── en.json      # English (default)
  ├── fr.json      # French
  ├── de.json      # German
  ├── es.json      # Spanish
  ├── ja.json      # Japanese
  ├── ko.json      # Korean
  └── zh_CN.json   # Chinese (Simplified)

Example en.json:

{
    "Name": "My Plugin",
    "Description": "A great plugin",
    "Actions": {
        "MyAction": {
            "Name": "My Action",
            "Tooltip": "Does something"
        }
    }
}

Example fr.json:

{
    "Name": "Mon Plugin",
    "Description": "Un super plugin",
    "Actions": {
        "MyAction": {
            "Name": "Mon Action",
            "Tooltip": "Fait quelque chose"
        }
    }
}

Property Inspector Localization

sdpi-components does not provide built-in localization for Property Inspector UI labels. To localize your Property Inspector:

1. Get language from connection info:

const { streamDeckClient } = SDPIComponents;

streamDeckClient.getConnectionInfo().then(info => {
    const language = info.applicationInfo.language; // e.g., "en", "fr", "de"
    updateUILabels(language);
});

2. Implement your own translation system:

const translations = {
    en: {
        name: "Name",
        enabled: "Enabled"
    },
    fr: {
        name: "Nom",
        enabled: "Activé"
    }
};

function updateUILabels(language) {
    const t = translations[language] || translations.en;
    document.querySelector('[setting="name"]').parentElement
        .querySelector('sdpi-item').setAttribute('label', t.name);
}

Best Practices

Use this checklist when building Property Inspectors with sdpi-components:

• Component selection

  • Use appropriate components for each input type (don't use textfield for booleans).
  • Leverage <sdpi-item> with label for consistent layout.
  • Use placeholder attributes to guide users.

• Settings management

  • Use the setting attribute on components for automatic binding.
  • Use nested paths (e.g., "user.name") for organized settings.
  • Use global attribute only when settings should be shared across actions.
  • Provide sensible default values so actions work immediately.

• Data sources

  • Use data sources for dynamic content (devices, API results, etc.).
  • Implement proper error handling in plugin data source handlers.
  • Use hot-reload for real-time updates when appropriate.
  • Provide meaningful loading text for better UX.

• Performance

  • Keep Property Inspector HTML/CSS/JavaScript files small.
  • Avoid blocking operations in Property Inspector code.
  • Use data sources efficiently (cache when appropriate).

• Distribution

  • Always use local references to sdpi-components.js in distributed plugins.
  • Test Property Inspector without an internet connection.
  • Ensure all referenced assets are included in the plugin bundle.

• User experience

  • Keep interfaces simple and intuitive.
  • Use clear labels and helpful tooltips (info attribute on <sdpi-item>).
  • Group related settings logically.
  • Validate user input where appropriate (use pattern on textfield, min/max on range).

• Communication

  • Use streamDeckClient for advanced communication patterns.
  • Handle cases where the plugin might not be ready.
  • Implement proper error handling for communication failures.

</html>

Pattern 2: Dynamic Select with Data Source

<!doctype html>
<html>
<head lang="en">
    <meta charset="utf-8" />
    <script src="sdpi-components.js"></script>
</head>
<body>
    <sdpi-item label="Device">
        <sdpi-select
            setting="device"
            datasource="getDevices"
            loading="Loading devices..."
            placeholder="Select a device">
        </sdpi-select>
    </sdpi-item>

    <script>
        const { streamDeckClient } = SDPIComponents;
        
        // Listen for device updates
        streamDeckClient.sendToPropertyInspector.subscribe(ev => {
            if (ev.payload.event === "deviceListUpdated") {
                // Refresh the select
                document.querySelector('[setting="device"]').refresh();
            }
        });
    </script>
</body>
</html>

Pattern 3: Conditional UI Updates

<!doctype html>
<html>
<head lang="en">
    <meta charset="utf-8" />
    <script src="sdpi-components.js"></script>
</head>
<body>
    <sdpi-item label="Mode">
        <sdpi-select setting="mode">
            <option value="simple">Simple</option>
            <option value="advanced">Advanced</option>
        </sdpi-select>
    </sdpi-item>
    
    <div id="advanced-settings" style="display: none;">
        <sdpi-item label="Advanced Option">
            <sdpi-textfield setting="advancedOption"></sdpi-textfield>
        </sdpi-item>
    </div>

    <script>
        const { streamDeckClient } = SDPIComponents;
        const modeSelect = document.querySelector('[setting="mode"]');
        const advancedDiv = document.getElementById('advanced-settings');
        
        // Listen for settings changes
        streamDeckClient.didReceiveSettings.subscribe(ev => {
            const mode = ev.payload.settings?.mode;
            if (mode === 'advanced') {
                advancedDiv.style.display = 'block';
            } else {
                advancedDiv.style.display = 'none';
            }
        });
        
        // Also handle local changes
        modeSelect.addEventListener('change', (e) => {
            if (e.target.value === 'advanced') {
                advancedDiv.style.display = 'block';
            } else {
                advancedDiv.style.display = 'none';
            }
        });
    </script>
</body>
</html>

Pattern 4: Global Settings with Action Settings

<!doctype html>
<html>
<head lang="en">
    <meta charset="utf-8" />
    <script src="sdpi-components.js"></script>
</head>
<body>
    <!-- Global settings (shared across all actions) -->
    <sdpi-item label="API Key">
        <sdpi-textfield setting="apiKey" global></sdpi-textfield>
    </sdpi-item>
    
    <!-- Action-specific settings -->
    <sdpi-item label="Action Name">
        <sdpi-textfield setting="actionName"></sdpi-textfield>
    </sdpi-item>
    
    <sdpi-item label="Enabled">
        <sdpi-checkbox setting="enabled"></sdpi-checkbox>
    </sdpi-item>
</body>
</html>

How to Use This Skill with an Agent

When you invoke a coding agent to work with sdpi-components:

1. State clearly that you are working on a Property Inspector using sdpi-components for an Elgato Stream Deck plugin.
2. Ask the agent to follow this skill for:
   • Selecting appropriate sdpi-components for different input types.
   • Configuring components with setting attributes.
   • Implementing data sources for dynamic content.
   • Using Stream Deck Client API for advanced communication.
   • Handling settings persistence (action-specific or global).
   • Debugging Property Inspector issues related to sdpi-components.
3. Provide any existing code or manifest files so the agent can:
   • Avoid duplicating components or settings.
   • Reuse existing settings structures.
   • Maintain consistency with current plugin implementation.

This ensures a consistent, robust Property Inspector development workflow using the official sdpi-components library.
