integration-astro-view-transitions

To integrate PostHog analytics into an Astro app using view transitions, wrap your pages in a reusable layout with ClientRouter and add an inline PostHog snippet wrapped in an initialization guard to prevent duplicate loading.

PostHog initializes multiple times with Astro ClientRouter view transitions because soft navigations re-execute scripts. A guarded initialization pattern prevents this by checking if the script already exists before loading the PostHog snippet again.

To track pageviews during Astro soft navigations with PostHog, use a ClientRouter layout pattern that captures pageview events automatically when view transitions occur, ensuring accurate tracking across route changes.

Yes, you need environment variables to configure PostHog in your Astro project. You must define variables for your PostHog host and project token to correctly authenticate and route analytics data from your inline snippet.

Yes, you can identify users and track events with PostHog in an Astro view transitions app. The integration supports user identification on login, custom event tracking, error tracking, and resetting user data on logout.

Adding PostHog to Astro without an initialization guard causes duplicate script execution during ClientRouter soft navigations, leading to multiple PostHog instances, inflated analytics data, and potential memory leaks.
