Logging & Observability (Frontend Standard)

This document defines the minimum observability bar for Next.js frontends.

Minimum bar (required)

Server-side (Route Handlers, Server Components)

• Log request summaries for BFF endpoints (method, route, status, duration).
• Preserve correlation headers where applicable (e.g., X-Request-Id).
• Redact secrets/PII.

Client-side

• Avoid logging PII and secrets.
• Prefer actionable, user-safe error messaging.

Error tracking tooling (project-dependent)

We do not mandate a single vendor across projects.

Standards requirement:

• The project must choose and document an approach (vendor tool or none), and meet the minimum bar above.
