npm install @reveldigital/client-sdk
Copy

Quick Start

import { createPlayerClient, EventType } from "@reveldigital/client-sdk";

const client = createPlayerClient();

// Listen for player events
client.on(EventType.START, () => {
  console.log('Player started');
});

// Get device information
const deviceTime = await client.getDeviceTime();
const deviceKey = await client.getDeviceKey();

// Send a callback to the player
client.callback('hello', 'world');

Framework Integration

React Integration

Basic Setup

// hooks/usePlayerClient.ts
import { useEffect, useState, useCallback } from 'react';
import { createPlayerClient, EventType, PlayerClient } from '@reveldigital/client-sdk';

export const usePlayerClient = () => {
  const [client] = useState<PlayerClient>(() => createPlayerClient());
  const [isPlayerActive, setIsPlayerActive] = useState(false);
  const [deviceInfo, setDeviceInfo] = useState<{
    key?: string;
    timezone?: string;
    language?: string;
  }>({});

  useEffect(() => {
    // Set up event listeners
    client.on(EventType.START, () => {
      setIsPlayerActive(true);
    });

    client.on(EventType.STOP, () => {
      setIsPlayerActive(false);
    });

    client.on(EventType.COMMAND, (data) => {
      console.log('Received command:', data);
    });

    // Load device information
    const loadDeviceInfo = async () => {
      try {
        const [key, timezone, language] = await Promise.all([
          client.getDeviceKey(),
          client.getDeviceTimeZoneName(),
          client.getLanguageCode()
        ]);

          timezone: timezone || undefined,
          language: language || undefined
        });
      } catch (error) {
        console.error('Failed to load device info:', error);
      }
    };

}
Copy

Best Practices

Error Handling

import { createPlayerClient } from "@reveldigital/client-sdk";

const client = createPlayerClient();

try {
  const deviceKey = await client.getDeviceKey();
  if (deviceKey) {
    // Handle success
    console.log('Device key:', deviceKey);
  } else {
    // Handle null response
    console.warn('Device key not available');
  }
} catch (error) {
  // Handle errors
  console.error('Failed to get device key:', error);
}
Copy

Performance Considerations

• Create the client instance once and reuse it
• Clean up event listeners when components unmount
• Use debouncing for frequent callback calls
• Cache device information when possible

Security Notes

• Device information should be treated as sensitive
• Validate all data received from player events
• Use HTTPS for any external API calls from your content

Deployment with GitHub Actions

There are two deployment options available depending on your project type:

For Webapps

The Revel Digital Webapp Deploy Action makes it easy to automatically deploy your web applications to your Revel Digital account whenever you push code to your repository.

Setting up the GitHub Action for Webapps

1. Get your API Key: First, obtain your Revel Digital API key from your account settings.

2. Add API Key to GitHub Secrets:

   • Go to your repository settings
   • Navigate to "Secrets and variables" → "Actions"
   • Create a new secret named REVEL_API_KEY with your API key as the value

3. Create the workflow file: Add .github/workflows/deploy.yml to your repository:

For Gadgets

Gadgets are deployed to GitHub Pages and use the Gadgetizer tool for packaging. This approach doesn't require a Revel Digital API key and leverages GitHub's built-in Pages hosting.

Setting up the GitHub Action for Gadgets

1. Enable GitHub Pages:

   • Go to your repository settings
   • Navigate to "Pages"
   • Set the source to "GitHub Actions"

2. Create the workflow file: Add .github/workflows/deploy.yml to your repository:

Action Inputs (For Webapps)

Input	Required	Description	Default
api-key	✅	Your Revel Digital API key (use GitHub secrets)	-
name	❌	Name for the webapp	From package.json
version	❌	Version of the webapp	From package.json
environment	❌	Deployment environment	Production
distribution-location	❌	Folder containing built assets	From package.json
tags	❌	Extra tags for smart scheduling (comma-delimited)	-
group-name	❌	Group name as regex pattern	-

Gadget Deployment Notes

For gadgets, the deployment process is simpler as it uses GitHub Pages:

• No API Key Required: Gadgets don't need a Revel Digital API key
• GitHub Pages Hosting: Content is automatically hosted on GitHub Pages
• Gadgetizer Processing: The @reveldigital/gadgetizer tool processes your content for optimal display
• Output Directory: Ensure your publish_dir matches your build output (commonly ./dist, ./build, or ./public)
• Branch Protection: Consider protecting your main branch to prevent accidental deployments

Environment Management

You can deploy to different environments based on your branch strategy:

# Deploy to Development for feature branches
# Deploy to Production for main branch
environment: ${{ github.ref_name == 'main' && 'Production' || 'Development' }}

# Or use custom logic
environment: ${{ 
  github.ref_name == 'main' && 'Production' || 
  github.ref_name == 'staging' && 'Staging' || 
  'Development' 
}}

Best Practices

For Webapps

1. Use Semantic Versioning: Let the action pull version from package.json or use Git tags
2. Environment Separation: Use different environments for different branches
3. Tag Management: Use meaningful tags for content organization and smart scheduling
4. Build Optimization: Ensure your build process creates optimized, production-ready assets
5. Security: Always use GitHub Secrets for API keys, never commit them to your repository

For Gadgets

1. GitHub Pages Setup: Ensure GitHub Pages is properly configured in your repository settings
2. Build Output: Verify your build process outputs to the correct directory specified in publish_dir
3. Gadgetizer Compatibility: Test that your content works correctly with the Gadgetizer tool
4. Branch Strategy: Use branch protection rules to control when deployments occur
5. Asset Optimization: Optimize images and other assets for signage display performance

Troubleshooting

Webapp Issues

Webapp Issues

• Build Failures: Ensure your build command works locally before deploying
• Permission Issues: Verify your API key has the necessary permissions in Revel Digital
• Path Issues: Check that distribution-location points to the correct build output folder
• Environment Issues: Confirm the environment name exists in your Revel Digital account
