tRPC provides end-to-end type safety for full-stack TypeScript projects, while Express with OpenAPI suits backends serving external clients. This Skill routes you to the right choice based on your architecture needs, client types, and integration constraints.

Authentication strategy selection depends on your API layer, user model, and deployment context. This Skill provides a decision framework covering session-based, token, and provider-specific approaches tailored to tRPC, Express, and Prisma setups.

This Skill provides unified project scaffolding with folder structures, example setup commands, and integration notes for combining Prisma data modeling, Zod validation, and your chosen API layer into a cohesive backend.

Zod enables runtime schema validation while Prisma handles type-safe database access. This Skill shows how to integrate both across data modeling, validation layers, and API responses for consistent type safety end-to-end.

This Skill covers observability with Pino logging, testing with Vitest, and containerization with Docker. It provides decision trees and integration guidance for deploying fully instrumented TypeScript backends across environments.

Yes. This Skill supports both tRPC (full-stack TypeScript) and Express with OpenAPI for external-facing REST APIs, with separate decision paths and scaffolding for each architectural approach.
