The Databuddy script automatically respects consent preferences by toggling tracking on and off based on the user's consent state.
## Script Implementation
1. **Adding the Databuddy script to c15t**
import \{ configureConsentManager } from 'c15t';
import \{ databuddy } from '@c15t/scripts/databuddy';
configureConsentManager(\{
// ...
scripts: \[
databuddy(\{
clientId: 'your-client-id',
scriptUrl: 'https\://cdn.databuddy.cc/databuddy.js',
apiUrl: 'https\://basket.databuddy.cc',
options: \{
trackScreenViews: true,
trackOutgoingLinks: true,
}
}),
],
});import \{ databuddy } from '@c15t/scripts/databuddy';
import \{ ConsentManagerProvider } from '@c15t/react';
export function App(\{ children }: \{ children: React.ReactNode }) \{
return (
\
\{children}
\
);
}'use client';
import \{ databuddy } from '@c15t/scripts/databuddy';
import \{ ClientSideOptionsProvider } from '@c15t/nextjs/client';
export function ConsentManagerClient(\{ children }: \{ children: React.ReactNode }) \{
return (
\
\{children}
\
);
}import \{ databuddy } from '@c15t/scripts/databuddy';
import \{ ConsentManagerProvider } from '@c15t/nextjs';
export function App(\{ children }: \{ children: React.ReactNode }) \{
return (
\
\{children}
\
);
}
2. **Using Databuddy in your application** Once initialized, Databuddy is available globally via window\.databuddy or window\.db:
```ts
// Track a custom event
window.databuddy?.trackCustomEvent('button_clicked', {
button_id: 'signup',
page: '/landing'
});
// Or use the shorthand
window.db?.track('purchase_completed', {
amount: 99.99,
currency: 'USD'
});
// Track a screen view manually
window.databuddy?.screenView('/dashboard', {
user_role: 'admin'
});
// Set global properties for all events
window.databuddy?.setGlobalProperties({
app_version: '1.2.3',
environment: 'production'
});
```
## How Consent Management Works
The Databuddy integration automatically handles consent management:
1. **Before Script Load**: Sets `window.databuddyConfig.disabled` based on initial consent state
2. **On Consent Grant**: Enables tracking by setting `window.databuddy.options.disabled = false`
3. **On Consent Revoke**: Disables tracking by setting `window.databuddy.options.disabled = true`
This ensures that no tracking occurs without user consent, keeping your analytics privacy-compliant.
## Configuration Options
The `options` parameter allows you to customize Databuddy's behavior:
```ts
databuddy({
clientId: 'your-client-id',
scriptUrl: 'https://cdn.databuddy.cc/databuddy.js',
apiUrl: 'https://basket.databuddy.cc', // Optional, defaults to basket.databuddy.cc, change if self-hosting
options: {
// Tracking options
trackScreenViews: true, // Automatically track page views
trackOutgoingLinks: true, // Track clicks on external links
trackAttributes: false, // Track data-track attributes on elements
trackErrors: false, // Track JavaScript errors
trackPerformance: true, // Track performance metrics
trackWebVitals: false, // Track Core Web Vitals
// Network options
enableBatching: false, // Batch events before sending
batchSize: 10, // Events per batch
batchTimeout: 2000, // Batch timeout in ms
samplingRate: 1.0, // Sample rate (0.0-1.0)
}
})
```
## Types
### DatabuddyConsentOptions
| Property | Type | Description | Default | Required |
| :-------- | :------------------------------------ | :--------------------------------------------------------------------------------------------------------------------------------- | :--------------------------------------- | :--------: |
| clientId | string | Your Databuddy client ID. | - | ✅ Required |
| apiUrl | string \| undefined | Your Databuddy API URL. | 'https\://basket.databuddy.cc' | Optional |
| scriptUrl | string \| undefined | The Databuddy script URL. | 'https\://cdn.databuddy.cc/databuddy.js' | Optional |
| options | Record\ \| undefined | Additional configuration options for Databuddy. | - | Optional |
| script | any | Override or extend the default script values.
Default values:
- \`id\`: 'databuddy'
- \`category\`: 'measurement' | - | Optional |
### Script
| Property | Type | Description | Default | Required |
| :------------------------- | :------------------------------------------------ | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :------ | :--------: |
| id | string | Unique identifier for the script | - | ✅ Required |
| src | string \| undefined | URL of the script to load | - | Optional |
| textContent | string \| undefined | Inline JavaScript code to execute | - | Optional |
| category | HasCondition\ | Consent category or condition required to load this script | - | ✅ Required |
| callbackOnly | boolean \| undefined | Whether this is a callback-only script that doesn't need to load an external resource.
When true, no script tag will be added to the DOM, only callbacks will be executed.
This is useful for:
- Managing consent for libraries already loaded on the page
- Enabling/disabling tracking features based on consent changes
- Running custom code when consent status changes without loading external scripts
Example use cases:
- Enabling/disabling Posthog tracking
- Configuring Google Analytics consent mode
- Managing cookie consent for embedded content | false | Optional |
| persistAfterConsentRevoked | boolean \| undefined | Whether the script should persist after consent is revoked. | false | Optional |
| alwaysLoad | boolean \| undefined | Whether the script should always load regardless of consent state.
This is useful for scripts like Google Tag Manager or PostHog that manage
their own consent state internally. The script will load immediately and
never be unloaded based on consent changes.
Note: When using this option, you are responsible for ensuring the script
itself respects user consent preferences through its own consent management. | false | Optional |
| fetchPriority | "high" \| "low" \| "auto" \| undefined | Priority hint for browser resource loading | - | Optional |
| attributes | Record\ \| undefined | Additional attributes to add to the script element | - | Optional |
| async | boolean \| undefined | Whether to use async loading | - | Optional |
| defer | boolean \| undefined | Whether to defer script loading | - | Optional |
| nonce | string \| undefined | Content Security Policy nonce | - | Optional |
| anonymizeId | boolean \| undefined | Whether to use an anonymized ID for the script element, this helps ensure the script is not blocked by ad blockers | true | Optional |
| target | "head" \| "body" \| undefined | Where to inject the script element in the DOM.
- \`'head'\`: Scripts are appended to \`\\` (default)
- \`'body'\`: Scripts are appended to \`\\`
Use \`'body'\` for scripts that:
- Need to manipulate DOM elements that don't exist until body loads
- Should load after page content for performance reasons
- Are required by third-party services to be in the body
Use \`'head'\` (default) for scripts that:
- Need to track early page events (analytics)
- Should be available before page render
- Most tracking/analytics scripts | 'head' | Optional |
| onBeforeLoad | ((info: ScriptCallbackInfo) => void) \| undefined | Callback executed before the script is loaded | - | Optional |
| onLoad | ((info: ScriptCallbackInfo) => void) \| undefined | Callback executed when the script loads successfully | - | Optional |
| onDelete | ((info: ScriptCallbackInfo) => void) \| undefined | Callback executed when the script is being unloaded/removed | - | Optional |
| onError | ((info: ScriptCallbackInfo) => void) \| undefined | Callback executed if the script fails to load | - | Optional |
| onConsentChange | ((info: ScriptCallbackInfo) => void) \| undefined | Callback executed whenever the consent store is changed.
This callback only applies to scripts already loaded. | - | Optional |
