Quick Reference Example

Here’s a complete example showing the most common SDK methods: 
import Encore from '@encorekit/web-sdk';

// 1. Configure SDK
Encore.configure({
  apiKey: 'pk_your_api_key_here',
  logLevel: 'debug'
});

// 2. Identify user (optional)
Encore.identify('user-123', {
  email: 'user@example.com',
  subscriptionTier: 'free'
});

// 3. Present offer
const result = await Encore.presentOffer();

if (result.granted) {
  console.log('Entitlement granted:', result.entitlement);
}

// 4. Check entitlements
if (Encore.isActive({ type: 'freeTrial' })) {
  unlockPremiumFeatures();
}

// 5. Subscribe to changes
const unsubscribe = Encore.on('entitlementChanged', (event) => {
  console.log('Entitlement changed:', event);
  updateUI();
});

// 6. Cleanup
unsubscribe();

​
TypeScript Support

The SDK includes comprehensive TypeScript type definitions: 
import Encore, {
  type EntitlementType,
  type EntitlementScope,
  type PresentationResult,
  type UserAttributes,
  type EncoreConfig,
