Learners will receive a Certificate of Completion from Uplatz, validating their expertise in tRPC and type-safe API development. This certification demonstrates readiness for roles in full-stack development, API engineering, and TypeScript-first application design.

tRPC skills prepare learners for roles such as:

• Full-Stack Developer (tRPC + Next.js)

• API Engineer (TypeScript-first)

• Frontend Developer (React + tRPC)

• Backend Developer (Node.js + tRPC)

• Software Engineer (Type-safe systems)

As companies adopt TypeScript and type-safety-first development, tRPC is gaining traction as a lightweight alternative to REST/GraphQL, making it a valuable skill.

1. What is tRPC?
   tRPC is a TypeScript library for building type-safe APIs without schemas, inferring types from server to client.

2. How is tRPC different from GraphQL?
   GraphQL requires schemas and resolvers, while tRPC infers types automatically, reducing boilerplate.

3. What are routers and procedures in tRPC?
   Routers group API endpoints, and procedures define queries (read) or mutations (write).

4. What role does Zod play in tRPC?
   Zod validates input and output data, ensuring type safety at runtime.

5. How does tRPC integrate with Next.js?
   Through an API handler that exposes routers to the Next.js frontend with type inference.

6. What are the benefits of tRPC over REST?

• Full type safety

• No manual schema sync

• Faster developer iteration

7. How does middleware work in tRPC?
   Middlewares handle authentication, logging, and validation before executing procedures.

8. Can tRPC handle real-time APIs?
   Yes, with subscriptions and WebSockets.

9. How does tRPC improve developer productivity?
   By removing the need for manual API typing, reducing bugs and increasing speed.

10. Where is tRPC commonly used?
    In full-stack TypeScript apps, especially with Next.js, Prisma, and React.
