Article: Building Production-Ready tRPC APIs: The TypeScript Alternative to Apollo Federation

Summary

An editorial analyst details a successful migration from Apollo Federation to tRPC for API development, citing significant improvements in performance, stability, and developer experience. The company, handling 2.4 million daily requests across 12 microservices, reduced P95 response times from 85ms to 28ms and client bundle size by 80% (142KB to 28KB gzipped). This shift eliminated 89% of API-related bugs and cut CI/CD pipeline times by 40% by removing schema definitions and code generation steps. The architecture leverages a pnpm monorepo with Next.js 14 App Router, ensuring end-to-end TypeScript type safety and streamlining API contract management.

Key takeaway

For software engineers struggling with GraphQL Federation's complexity in a TypeScript monorepo, consider migrating to tRPC. Your team can expect a significant reduction in API-related bugs (up to 89%), faster CI/CD pipelines (40% improvement), and enhanced developer velocity, allowing you to ship features 40% faster. Evaluate tRPC for internal web applications where you control both client and server to leverage its end-to-end type safety and performance benefits.

Key insights

tRPC offers superior performance and type safety for TypeScript monorepos compared to GraphQL Federation.

Principles

• End-to-end type safety prevents API contract errors.
• Simpler tooling often yields better performance.
• Incremental migration reduces project risk.

Method

Migrate APIs using a strangler fig pattern, starting with low-risk read-only endpoints, then critical mutations, while running both systems in parallel to compare metrics.

In practice

• Use tRPC for internal TypeScript-only APIs.
• Implement React Query for client-side batching and caching.
• Validate inputs exclusively on the server with Zod.
