⚡ Quick Start

npm install @adkit.so/meta-pixel

import META from '@adkit.so/meta-pixel';

// 1. Initialize
META.init({ pixelIds: 'YOUR_PIXEL_ID' });

// 2. Track events
META.track('Purchase', { value: 99.99, currency: 'USD' });

That's it! 🎉

📦 Installation

npm install @adkit.so/meta-pixel

💡 Usage

Basic Initialization

Initialize the pixel as early as possible in your application entry point (e.g., main.ts, App.jsx, index.js).

import META from '@adkit.so/meta-pixel';

META.init({
    pixelIds: '1234567890',
    autoTrackPageView: true, // default: true
});

Tracking Events

// Track standard events
META.track('AddToCart', {
    value: 29.99,
    currency: 'USD',
    content_ids: ['SKU_123'],
    content_type: 'product',
});

// Track custom events
META.trackCustom('MyCustomEvent', {
    custom_param: 'value',
});

Multiple Instances

If you need separate instances for different parts of your application (rare):

import { createMetaPixel } from '@adkit.so/meta-pixel';

const marketingPixel = createMetaPixel();
marketingPixel.init({ pixelIds: 'MARKETING_ID' });

const productPixel = createMetaPixel();
productPixel.init({ pixelIds: 'PRODUCT_ID' });

⚙️ Configuration

Configuration Options

Option	Type	Default	Description
pixelIds	string | string[]	''	Required. Single pixel ID or array of pixel IDs
autoTrackPageView	boolean	true	Automatically track PageView on initialization
debug	boolean	false	Enable styled console logs with background colors
enableLocalhost	boolean	false	Enable tracking on localhost (useful for testing)

Multiple Pixels Example

META.init({
    pixelIds: ['PIXEL_ID_1', 'PIXEL_ID_2', 'PIXEL_ID_3'],
    debug: true,
});

🚀 Advanced Usage

Event Deduplication

Prevent duplicate event tracking by using unique event IDs. This is crucial when tracking conversions from both client and server (CAPI).

const orderId = '12345';

META.track(
    'Purchase',
    {
        value: 299.99,
        currency: 'USD',
        content_ids: ['SKU_123'],
    },
    {
        eventID: `order-${orderId}`, // Unique Event ID
    },
);

Check if Pixel is Loaded

Useful if you need to conditionally run logic based on whether the pixel script has loaded.

if (META.isLoaded()) {
    META.track('Purchase', { value: 99.99, currency: 'USD' });
} else {
    console.log('Pixel not loaded yet');
}

Debug Mode

When debug: true is passed to init(), you'll see beautiful styled console logs:

• 🔵 [Meta Pixel] Info messages (blue background)
• ✅ [Meta Pixel] Success messages (green background)
• ⚠️ [Meta Pixel] Warning messages (orange background)

META.init({
    pixelIds: 'YOUR_ID',
    debug: true,
});

📝 TypeScript Support

This package is written in TypeScript and bundles type definitions.

import type { StandardEvent, EventData, MetaPixelConfig } from '@adkit.so/meta-pixel';

const config: MetaPixelConfig = {
    pixelIds: '123',
};

const eventData: EventData = {
    value: 100,
    currency: 'USD',
};

❓ Troubleshooting

Pixel not loading?

1. Check your pixel ID - Make sure it's correct in your config
2. Enable debug mode - Set debug: true in init() to see detailed logs
3. Check browser console - Look for errors or warnings
4. Check Ad Blockers - Ad blockers often block the Meta Pixel script
5. Enable on localhost - Set enableLocalhost: true if testing locally

Events not showing in Meta Events Manager?

• Wait a few minutes - Events can take 5-20 minutes to appear
• Check Test Events - Use the Test Events tool in Meta Events Manager
• Verify event names - Standard events are case-sensitive
