PostHog integration for Astro with ClientRouter view transitions
— the description by PostHog

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a structured approach to integrating PostHog analytics into Astro projects that utilize the ClientRouter for view transitions. It addresses common challenges such as preventing initialization stack overflows during soft navigation and ensuring accurate pageview tracking. The guide includes best practices for component-based initialization, environment variable management, and user identification patterns.

What it does

  • Provides a reusable PostHog initialization component for Astro
  • Implements an initialization guard to prevent stack overflow errors during soft navigation
  • Configures automatic pageview tracking for SPA-like transitions
  • Outlines patterns for identifying users and tracking custom events
  • Demonstrates how to capture exceptions and errors within the application
  • Guides the setup of environment variables for secure API key management

When to use it

  • When adding PostHog analytics to an Astro project using ClientRouter
  • When you need to ensure analytics persist correctly across soft page transitions
  • When you need to track user behavior, custom events, or errors in an Astro app
  • When you want to follow established patterns for Astro and PostHog integration

Advantages

  • Prevents common initialization errors associated with Astro's view transitions
  • Ensures consistent analytics data collection across client-side navigation
  • Promotes clean, modular code through component-based integration
  • Follows security best practices by using environment variables

Usage examples

“How do I initialize PostHog in my Astro project with View Transitions?”
The agent will guide you to create a posthog.astro component with an initialization guard and import it into your layout.
“How can I track pageviews automatically during soft navigation in Astro?”
The agent will instruct you to set the capture_pageview option to 'history_change' within your PostHog initialization script.

PostHog integration for Astro (View Transitions)

This skill helps you add PostHog analytics to Astro (View Transitions) applications.

Workflow

Follow these steps in order to complete the integration:

  1. basic-integration-1.0-begin.md - PostHog Setup - Begin ← Start here

  2. basic-integration-1.1-edit.md - PostHog Setup - Edit

  3. basic-integration-1.2-revise.md - PostHog Setup - Revise

  4. basic-integration-1.3-conclude.md - PostHog Setup - Conclusion

Reference files

  • references/EXAMPLE.md - Astro (View Transitions) example project code

  • references/astro.md - Astro - docs

  • references/identify-users.md - Identify users - docs

  • references/basic-integration-1.0-begin.md - PostHog setup - begin

  • references/basic-integration-1.1-edit.md - PostHog setup - edit

  • references/basic-integration-1.2-revise.md - PostHog setup - revise

  • references/basic-integration-1.3-conclude.md - PostHog setup - conclusion

The example project shows the target implementation pattern. Consult the documentation for API details.

Key principles

  • Environment variables: Always use environment variables for PostHog keys. Never hardcode them.

  • Minimal changes: Add PostHog code alongside existing integrations. Don't replace or restructure existing code.

  • Match the example: Your implementation should follow the example project's patterns as closely as possible.

Framework guidelines

  • Always use the is:inline directive on PostHog script tags to prevent Astro from processing them and causing TypeScript errors

  • Use PUBLIC_ prefix for client-side environment variables in Astro (e.g., PUBLIC_POSTHOG_PROJECT_TOKEN)

  • Create a posthog.astro component in src/components/ for reusable initialization across pages

  • Import the PostHog component in a Layout and wrap all pages with that layout

  • Wrap PostHog initialization with a window.__posthog_initialized guard to prevent stack overflow during soft navigation

  • Set capture_pageview option to 'history_change' for automatic pageview tracking during soft navigation

  • Use the astro page-load event instead of just DOMContentLoaded to re-run scripts after soft navigation

Identifying users

Identify users during login and signup events. Refer to the example code and documentation for the correct identify pattern for this framework. If both frontend and backend code exist, pass the client-side session and distinct ID using X-POSTHOG-DISTINCT-ID and X-POSTHOG-SESSION-ID headers to maintain correlation.

Error tracking

Add PostHog error tracking to relevant files, particularly around critical user flows and API boundaries.

PostHog Astro View Transitions Example

This is an Astro example demonstrating PostHog integration with View Transitions (ClientRouter) for SPA-like navigation.

It uses the PostHog web snippet with special handling to prevent stack overflow errors during soft navigation, and shows how to:

  • Initialize PostHog with an initialization guard for View Transitions

  • Track pageviews automatically during soft navigation

  • Identify users after login

  • Track custom events from pages

  • Capture errors via posthog.captureException()

  • Reset PostHog state on logout

Features

  • View Transitions: Smooth client-side navigation with <ClientRouter />

  • Product analytics: Track login and burrito consideration events

  • Automatic pageview tracking: Uses capture_pageview: 'history_change' for soft navigation

  • Session replay: Enabled via PostHog snippet configuration

  • Error tracking: Manual error capture sent to PostHog

  • Simple auth flow: Demo login using localStorage

Getting started

1. Install dependencies
npm install
# or
pnpm install
2. Configure environment variables

Create a .env file in the project root:

PUBLIC_POSTHOG_PROJECT_TOKEN=your_posthog_project_token
PUBLIC_POSTHOG_HOST=https://us.i.posthog.com

Get your PostHog project token from your project settings in PostHog.

3. Run the development server
npm run dev
# or
pnpm dev

Open http://localhost:4321 in your browser.

Key integration points

PostHog initialization with View Transitions (src/components/posthog.astro)

When using Astro's View Transitions (ClientRouter), you must wrap the PostHog initialization with a guard to prevent stack overflow errors:

<script is:inline>
  // IMPORTANT: Guard against multiple initializations during view transitions
  if (!window.__posthog_initialized) {
    window.__posthog_initialized = true;
    !function(t,e){...}(document,window.posthog||[]);
    posthog.init('<ph_project_token>', {
      api_host: 'https://us.i.posthog.com',
      defaults: '2026-01-30',
      // IMPORTANT: Use 'history_change' for automatic pageview tracking during soft navigation
      capture_pageview: 'history_change'
    })
  }
</script>

Without this guard, ClientRouter's soft navigation can re-execute the inline script during page transitions, causing a stack overflow error.

The capture_pageview: 'history_change' option ensures pageviews are tracked automatically as users navigate between pages.

Layout with ClientRouter (src/layouts/PostHogLayout.astro)

The layout includes Astro's ClientRouter for smooth page transitions:

---
import { ClientRouter } from 'astro:transitions';
import PostHog from '../components/posthog.astro';
---
<html>
  <head>
    <ClientRouter />
    <PostHog />
  </head>
  ...
</html>
Handling View Transitions in scripts

When using View Transitions, you need to set up event listeners after each page navigation:

function setupPage() {
  // Your setup code here
}

// Run on initial page load
document.addEventListener("DOMContentLoaded", setupPage);

// Run after view transitions complete (for soft navigation)
document.addEventListener("astro:page-load", setupPage);
User identification (src/pages/index.astro)

After a successful "login", the app identifies the user and captures a login event:

window.posthog?.identify(username);
window.posthog?.capture("user_logged_in");
Event tracking (src/pages/burrito.astro)

The burrito page tracks a custom event when a user "considers" the burrito:

window.posthog?.capture("burrito_considered", {
  total_considerations: newCount,
  username: currentUser,
});
Logout and session reset (src/components/Header.astro)

On logout, both the local auth state and PostHog state are cleared:

window.posthog?.capture("user_logged_out");
localStorage.removeItem("currentUser");
window.posthog?.reset();
