Explore how Zod schema validation and tRPC solve the pain of REST APIs with manual types. Covers router setup, client-side type inference, error handling with Zod, migrating from REST, and when tRPC is and isn't the right tool.
Once you ship a public API, you can't change it freely. Compare four versioning strategies for evolving APIs without breaking clients, plus analysis of real-world choices by GitHub, Stripe, and Twilio.
Stop using 'any'. How to build reusable, type-safe components using Generics. Advanced patterns with extends, keyof, and infer.
Fixing the crash caused by props coming through as undefined from the parent component.
Troubleshooting absolute path import configuration issues in TypeScript/JavaScript projects. Exploring the 'Map vs Taxi Driver' analogy, CommonJS vs ESM history, and Monorepo setup.
The core value of Zod + tRPC in one line:
"Runtime validation (Zod) plus compile-time inference (tRPC) means a backend change immediately surfaces as a TypeScript error in the frontend."
This solves the root problem of "types are fine but runtime breaks" in REST + TypeScript stacks.
If you have external clients or non-TypeScript consumers, tRPC isn't the right tool. In that case, adding Zod for server-side validation in your existing REST setup already gets you most of the benefit.
For a full-stack TypeScript project where your team owns both sides? tRPC is worth a serious look.
