cross-platform-structured-logging

Structured logging across Node.js and Python APIs is established by configuring Pino and structlog to emit machine-readable JSON logs with a common schema. This unifies log fields like level, timestamp, message, trace_id, and service for centralized aggregation.

Trace correlation for FastAPI and Next.js requests works by propagating a trace_id across service boundaries using child loggers. This enables request-scoped context, allowing you to track a single transaction end-to-end across both Python and Node.js environments.

Yes, Firebase Functions logger can be used alongside Pino and structlog for unified logging. The system enforces a standard JSON schema across all three platforms, ensuring logs from Firebase, Node.js, and Python share identical fields for centralized querying.

The best way to redact PII in cross-platform JSON logs is to apply automatic PII redaction within your logging configuration. This securely handles sensitive fields before logs are emitted by Pino, structlog, or Firebase Functions logger, ensuring compliance.

Unified structured logging requires a standard schema encompassing level, timestamp, message, trace_id, and service. Enforcing this specific log schema across Next.js, FastAPI, and Firebase Functions guarantees machine-readable JSON output for centralized observability platforms.
