### PostHog Java Log Ingestion - Integrate PostHog log ingestion into Java applications using the OpenTelemetry protocol and OTLP exporters. - Use environment variables for PostHog keys and endpoints instead of hardcoding sensitive configuration data. - Implement structured logging with key-value properties and add log export alongside existing logging infrastructure.

### PostHog Integration for Angular - Create a singleton PosthogService using inject() to wrap the SDK and manage analytics across standalone components. - Store PostHog credentials in environment.ts files and avoid hardcoding keys directly into the application source code. - Identify users during authentication and pass session headers to maintain data correlation between frontend and backend services.

### PostHog Integration for React Router v7 - Follow the four-step setup workflow to integrate PostHog analytics into Data mode applications. - Use environment variables for keys and mirror the implementation patterns found in the provided example project. - Trigger analytics in event handlers, avoid useEffect for state logic, and use specific headers to maintain user identification.

### PostHog Ruby on Rails Integration - Install the posthog-rails gem and use PostHog.init in an initializer to manage the client lifecycle automatically. - Securely store API keys using environment variables or Rails credentials instead of hardcoding them in your application. - Use class-level PostHog.capture and PostHog.identify methods to track events and associate users across backend and background jobs.

### PostHog Integration for Nuxt 3.6 - Follow the four-step setup workflow to initialize PostHog analytics within your Nuxt 3.0 to 3.6 application. - Use environment variables for all PostHog keys and maintain consistency by following the provided example project patterns. - Identify users during authentication events and use specific headers to correlate client-side sessions with backend requests.

### PostHog Feature Flags for Ruby - Install the posthog-ruby gem and initialize the client using environment variables for API keys to ensure secure configuration. - Implement server-side flag evaluation to prevent UI flickering and use boolean flags as the default for simple feature toggling. - Always call client.shutdown in an ensure block for scripts and CLIs to prevent data loss and ensure proper event flushing.

### PostHog FastAPI Integration - Initialize the Posthog client within the FastAPI lifespan context manager and ensure proper shutdown to flush all pending events. - Use dependency injection for settings and user identification, ensuring PII is only sent via identify calls, never in capture events. - Follow the provided example project patterns and use environment variables for API keys to maintain secure and consistent tracking.

### PostHog Node.js Error Tracking - Initialize the SDK with enableExceptionAutocapture set to true and use environment variables for all sensitive configuration keys. - Implement captureException in global error handlers and specific catch blocks to ensure comprehensive visibility into application failures. - Upload source maps to resolve stack traces and configure flush settings to match the lifecycle of your server or serverless process.

### PostHog Log Ingestion for Other Languages - Configure OTLP exporters to send logs directly to PostHog's ingestion endpoint using the OpenTelemetry protocol. - Use environment variables for all sensitive configuration, including PostHog project keys and OTLP endpoints. - Implement structured logging with key-value pairs to enhance searchability without replacing existing application logging logic.
