Track Events

This feature allows you to track events that occur in your application. The `capture` method is used to log an event with a distinct user ID and any relevant properties.

const { PostHog } = require('posthog-node');
const client = new PostHog('YOUR_API_KEY');

client.capture({
  distinctId: 'user123',
  event: 'user_signed_up',
  properties: {
    plan: 'premium'
  }
});

Identify Users

This feature allows you to identify users and associate them with specific properties. The `identify` method is used to set or update user properties.

const { PostHog } = require('posthog-node');
const client = new PostHog('YOUR_API_KEY');

client.identify({
  distinctId: 'user123',
  properties: {
    email: 'user@example.com',
    name: 'John Doe'
  }
});

Feature Flags

This feature allows you to manage feature flags, enabling or disabling features for specific users. The `isFeatureEnabled` method checks if a feature flag is enabled for a given user.

const { PostHog } = require('posthog-node');
const client = new PostHog('YOUR_API_KEY');

client.isFeatureEnabled('new-feature', 'user123').then(isEnabled => {
  if (isEnabled) {
    console.log('Feature is enabled for this user');
  } else {
    console.log('Feature is not enabled for this user');
  }
});
