What primary tech stack does this skill support?

This skill is optimized for Next.js 14, tRPC, Express, TypeScript, Prisma (PostgreSQL), ClickHouse, and BullMQ/Redis.

How does it handle multi-tenant security?

It enforces strict tenant isolation by requiring projectId filtering on all database queries and utilizing specialized authentication middleware.

Does it provide guidance for background tasks?

Yes, it includes comprehensive checklists and architecture patterns for creating BullMQ queue processors and managing job life cycles in a worker package.

Why does it emphasize a layered architecture?

By delegating tRPC procedures and queue jobs to dedicated services, it ensures business logic is reusable, testable, and decoupled from the transport layer.

API Development

Standardizes backend development patterns for Next.js, tRPC, and BullMQ microservices using a layered architecture.

This skill provides a comprehensive framework for building robust, scalable backend systems within a Next.js 14 and tRPC ecosystem. It establishes best practices for layered architecture, separating tRPC procedures and queue processors from core business logic through dedicated services. Users benefit from standardized patterns for database access via Prisma and ClickHouse, multi-tenant isolation using projectId filtering, Redis-backed task queues with BullMQ, and integrated observability using OpenTelemetry. It is specifically designed to maintain high code quality and consistency across monorepo environments, ensuring type safety and reliable error handling throughout the application lifecycle.
