FAQPage Schema

How do I integrate PostHog JavaScript analytics into a web application?▼

You can integrate PostHog JavaScript web analytics by initializing the posthog-js SDK with your project token and host, enabling autocapture for automatic interaction tracking, and using environment variables for secure configuration management.

How does identify() link anonymous browsing sessions to known users in PostHog?▼

The PostHog identify() function links anonymous browsing sessions to authenticated users by assigning a unique user ID, which correlates captured events and user properties across different sessions and devices.

Can I use PostHog to track client-side clicks and form submissions automatically?▼

Yes, PostHog can automatically track client-side clicks and form submissions by enabling the autocapture feature during SDK initialization, which automatically records standard user interactions like page views and clicks.

What is the best way to securely configure PostHog web tracking without exposing API keys?▼

The most secure way to configure PostHog web tracking is by using environment-based configuration to inject your project token and host at build time, avoiding hardcoded API keys in your client-side code.

Does PostHog JavaScript integration require server-side instrumentation to track events?▼

No, PostHog JavaScript integration does not require server-side instrumentation because it enables client-side analytics by capturing user interactions like page views and clicks directly from the browser.

What are the limitations of using client-side PostHog JavaScript for web analytics?▼

Limitations of client-side PostHog JavaScript include potential tracking gaps from ad blockers or disabled JavaScript, requiring proper error handling and privacy considerations during frontend initialization to manage environment-based configuration failures.
