# `@trpc/server` > Create tRPC routers and connect them to a server. ## Documentation Full documentation for `@trpc/server` can be found [here](https://trpc.io/docs/router) ## Installation ```bash # npm npm install @trpc/server # Yarn yarn add @trpc/server # pnpm pnpm add @trpc/server # Bun bun add @trpc/server ``` We also recommend installing `zod` to validate procedure inputs. ## AI Agents If you use an AI coding agent, install tRPC skills for better code generation: ```bash npx @tanstack/intent@latest install ``` ## Basic Example ```ts import { initTRPC } from '@trpc/server'; import { CreateHTTPContextOptions, createHTTPServer, } from '@trpc/server/adapters/standalone'; import { z } from 'zod'; // Initialize a context for the server function createContext(opts: CreateHTTPContextOptions) { return {}; } // Get the context type type Context = Awaited>; // Initialize tRPC const t = initTRPC.context().create(); // Create main router const appRouter = t.router({ // Greeting procedure greeting: t.procedure .input( z.object({ name: z.string(), }), ) .query(({ input }) => `Hello, ${input.name}!`), }); // Export the app router type to be imported on the client side export type AppRouter = typeof appRouter; // Create HTTP server const { listen } = createHTTPServer({ router: appRouter, createContext, }); // Listen on port 2022 listen(2022); ```
