Comprehensive backend development guidelines for Langfuse's Next.js 14/tRPC/Express/TypeScript monorepo. Use when building tRPC routers, public API endpoints, BullMQ queue processors, or services, and when working with tRPC procedures, Next.js API routes, Prisma database access, ClickHouse analytics queries, Redis queues, OpenTelemetry instrumentation, Zod v4 validation, env.mjs configuration, tenant isolation patterns, or async patterns. Covers layered architecture, dual database system (PostgreSQL + ClickHouse), projectId filtering, traceException error handling, observability patterns, and testing strategies (Jest for web, vitest for worker).
