合并路由

将代码中的所有 API 代码写入同一个文件中并不是一个好主意。将路由与其他路由合并很容易。

¥Writing all API-code in your code in the same file is not a great idea. It's easy to merge routers with other routers.

与子路由合并

¥Merging with child routers

与 t.mergeRouters 合并

¥Merging with t.mergeRouters

如果你希望将所有过程放在一个名称空间中，则可以使用 t.mergeRouters

¥If you prefer having all procedures flat in one single namespace, you can instead use t.mergeRouters

ts
// @filename: trpc.ts
import { initTRPC } from '@trpc/server';
const t = initTRPC.create();
 
 
export const router = t.router;
export const publicProcedure = t.procedure;
export const mergeRouters = t.mergeRouters;
 
// @filename: routers/_app.ts
import { router, publicProcedure, mergeRouters } from '../trpc';
import { z } from 'zod';
 
import { userRouter } from './user';
import { postRouter } from './post';
 
const appRouter = mergeRouters(userRouter, postRouter)
 
export type AppRouter = typeof appRouter;
 
// @filename: routers/post.ts
import { router, publicProcedure } from '../trpc';
import { z } from 'zod';
export const postRouter = router({
  postCreate: publicProcedure
    .input(
      z.object({
