FAQPage Schema

How do I build a type-safe API in Next.js?▼

To build a type-safe API in Next.js, you use tRPC v11 to establish end-to-end TypeScript inference, ensuring compile-time validated endpoints and reducing runtime errors. This approach provides automatic type safety between server and client code.

What is the best way to structure a scalable tRPC backend?▼

A scalable tRPC backend requires structured project setup guidelines that separate server and client code logically. This structure supports maintainability and scalability, allowing professional developers to manage input validation, middleware, and error handling effectively.

Can I use tRPC with Next.js for input validation and error handling?▼

Yes, you can use tRPC with Next.js for input validation and error handling. tRPC v11 supports comprehensive middleware integration, allowing you to validate user data inputs and manage application errors securely across server and client boundaries.

How does TypeScript inference work with tRPC client-server integration?▼

TypeScript inference with tRPC client-server integration automatically maps server-side API endpoint types directly to your Next.js client code. This eliminates manual type synchronization, ensuring secure data retrieval and minimal runtime errors across your web application.

Do I need TypeScript to implement end-to-end type safety with tRPC?▼

Yes, you need TypeScript to implement end-to-end type safety with tRPC, as the framework relies entirely on TypeScript inference to automatically validate API endpoints and securely link server procedures with client-side data consumption.
