Posthog Analytics

Solid setup for PostHog integration with opinionated patterns for event tracking and feature flags. Covers Next.js, React, Python, and Node with actual code for user identification, pageview tracking, and the provider setup you need. The event naming convention (object_action, snake_case, past tense) is prescriptive in a good way, and the breakdown of core events by category (auth, onboarding, feature usage) gives you a template instead of making you figure it out from scratch. Emphasizes tracking what informs decisions rather than everything, which is the right philosophy but harder to follow than it sounds.
