Sentry SDK Patterns

Overview

Production patterns for @sentry/node (v8+) and sentry-sdk (Python 2.x+) covering scoped error context, breadcrumb strategies, event filtering with beforeSend, custom fingerprinting for issue grouping, and performance instrumentation with spans. All examples use real Sentry SDK APIs.

Prerequisites

• Sentry SDK v8+ installed (@sentry/node, @sentry/react, or sentry-sdk)
• SENTRY_DSN environment variable configured
• Familiarity with async/await (TypeScript) or context managers (Python)

Instructions
