How does it handle events in serverless environments?

It implements captureImmediate() or explicit flush() patterns to ensure that analytics events are successfully sent before the serverless function execution terminates.

Why does it require a specific defaults date?

The '2026-01-30' setting ensures your implementation uses the latest PostHog behaviors, including improved automatic SPA page tracking and more reliable event processing.

Can I use this for server-side rendering (SSR)?

Yes, the skill includes specific patterns for posthog-node and provides guards to ensure client-side SDKs only initialize in the browser to prevent server crashes.

Does this handle feature flags?

Yes, PostHog provides both analytics and feature flags in a single SDK; this skill configures the necessary provider and clients to use both features.

Analíticas y Monitorización

Configures comprehensive product analytics and feature flag infrastructure using PostHog for both client-side and server-side applications.

This skill automates the integration of PostHog, a powerful all-in-one platform for product analytics and feature management. It provides structured guidance for setting up posthog-js with proper provider patterns and posthog-node for server-side event tracking, ensuring reliable data collection through automatic SPA tracking and serverless flush handling. Ideal for developers needing a robust, usage-based alternative to fragmented analytics tools, it enforces best practices like environment variable security, user identification flows, and optimized session tracking while preventing common pitfalls in serverless environments.
