SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @trpc/server, @trpc/client, superjson, next-auth.js, prisma, drizzle-orm, tailwindcss, trpc, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill simplifies and enhances the development of Next.js applications using tRPC, ensuring robust, type-safe APIs with minimal boilerplate.

Core Features & Use Cases

Type-safe APIs: Build and consume APIs without schemas, code generation, or runtime errors.
Project Structure: Offers a detailed project structure for efficient Next.js app development.
Server-Side Setup: Provides instructions for setting up a tRPC backend, including router creation and procedure handling.
Client-Side Setup: Guides on configuring tRPC clients and integrating with React Query.
Best Practices: Outlines key best practices for input validation, router organization, middleware implementation, and more.
Use Case: Develop a Next.js app with tRPC and React Query to handle user authentication, manage session state, and provide real-time data fetching.

Quick Start

Run the command to initialize a tRPC backend in your Next.js project.

FAQPage Schema

How do I build type-safe APIs in Next.js without code generation?▼

You can build type-safe APIs in Next.js without code generation by using tRPC to define router procedures that automatically infer TypeScript types on the client, eliminating runtime errors and schema synchronization boilerplate.

What is the best way to structure a Next.js project using tRPC?▼

The best way to structure a Next.js project using tRPC is to follow a dedicated project layout that separates server-side router creation and procedure handling from client-side React Query integration.

How do I set up tRPC client and server integration with React Query?▼

You set up tRPC client and server integration with React Query by configuring the tRPC backend router and initializing the tRPC client on the frontend to handle data fetching and session state management seamlessly.

Can I use tRPC with Prisma and next-auth for authentication?▼

Yes, you can use tRPC with Prisma and next-auth for authentication by implementing middleware procedures that manage session state and validate user inputs during real-time data fetching operations.

What are the limitations of using tRPC for API development?▼

A key limitation of using tRPC for API development is its tight coupling to the TypeScript ecosystem, meaning your API endpoints are not easily consumable by external clients written in other programming languages.
