合併路由器

在程式碼中將所有 API 程式碼寫在同一個檔案中並非好主意。合併路由器與其他路由器很簡單。

定義內嵌子路由器

定義內嵌子路由器時，您可以將路由器表示為一般物件。

在下例中，nested1 和 nested2 相等

server/_app.ts
ts
import * as trpc from '@trpc/server';
import { publicProcedure, router } from './trpc';
 
const appRouter = router({
  // Shorthand plain object for creating a sub-router
  nested1: {
    proc: publicProcedure.query(() => '...'),
  },
  // Equivalent of:
  nested2: router({
    proc : publicProcedure.query(() => '...'),
  }),
});

server/_app.ts
ts
import * as trpc from '@trpc/server';
import { publicProcedure, router } from './trpc';
 
const appRouter = router({
  // Shorthand plain object for creating a sub-router
  nested1: {
    proc: publicProcedure.query(() => '...'),
  },
  // Equivalent of:
  nested2: router({
    proc : publicProcedure.query(() => '...'),
  }),
});

與子路由器合併

server.ts
ts
// @filename: trpc.ts
import { initTRPC } from '@trpc/server';
const t = initTRPC.create();
 
 
 
export const router = t.router;
export const publicProcedure = t.procedure;
 
// @filename: routers/_app.ts
import { router } from '../trpc';
import { z } from 'zod';
 
import { userRouter } from './user';
import { postRouter } from './post';
 
const appRouter = router({
  user: userRouter, // put procedures under "user" namespace
  post: postRouter, // put procedures under "post" namespace
});
 
// You can then access the merged route with
// http://localhost:3000/trpc/<NAMESPACE>.<PROCEDURE>
 
export type AppRouter = typeof appRouter;
 
 
// @filename: routers/post.ts
import { router, publicProcedure } from '../trpc';
import { z } from 'zod';
export const postRouter = router({
  create: publicProcedure
    .input(
      z.object({
        title: z.string(),
      }),
    )
    .mutation((opts) => {
      const { input } = opts;
               
const input: {
    title: string;
}
      // [...]
    }),
  list: publicProcedure.query(() => {
    // ...
    return [];
  }),
});
 
// @filename: routers/user.ts
import { router, publicProcedure } from '../trpc';
import { z } from 'zod';
export const userRouter = router({
  list: publicProcedure.query(() => {
    // [..]
    return [];
  }),
});
 

server.ts
ts
// @filename: trpc.ts
import { initTRPC } from '@trpc/server';
const t = initTRPC.create();
 
 
 
export const router = t.router;
export const publicProcedure = t.procedure;
 
// @filename: routers/_app.ts
import { router } from '../trpc';
import { z } from 'zod';
 
import { userRouter } from './user';
import { postRouter } from './post';
 
const appRouter = router({
  user: userRouter, // put procedures under "user" namespace
  post: postRouter, // put procedures under "post" namespace
});
 
// You can then access the merged route with
// http://localhost:3000/trpc/<NAMESPACE>.<PROCEDURE>
 
export type AppRouter = typeof appRouter;
 
 
// @filename: routers/post.ts
import { router, publicProcedure } from '../trpc';
import { z } from 'zod';
export const postRouter = router({
  create: publicProcedure
    .input(
      z.object({
        title: z.string(),
      }),
    )
    .mutation((opts) => {
      const { input } = opts;
               
const input: {
    title: string;
}
      // [...]
    }),
  list: publicProcedure.query(() => {
    // ...
    return [];
  }),
});
 
// @filename: routers/user.ts
import { router, publicProcedure } from '../trpc';
import { z } from 'zod';
export const userRouter = router({
  list: publicProcedure.query(() => {
    // [..]
    return [];
  }),
});
 

與 t.mergeRouters 合併

如果您偏好將所有程序平整在單一命名空間中，您可以改用 t.mergeRouters

server.ts
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({
        title: z.string(),
      }),
    )
    .mutation((opts) => {
      const { input } = opts;
               
const input: {
    title: string;
}
      // [...]
    }),
  postList: publicProcedure.query(() => {
    // ...
    return [];
  }),
});
 
 
// @filename: routers/user.ts
import { router, publicProcedure } from '../trpc';
import { z } from 'zod';
export const userRouter = router({
  userList: publicProcedure.query(() => {
    // [..]
    return [];
  }),
});
 

server.ts
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({
        title: z.string(),
      }),
    )
    .mutation((opts) => {
      const { input } = opts;
               
const input: {
    title: string;
}
      // [...]
    }),
  postList: publicProcedure.query(() => {
    // ...
    return [];
  }),
});
 
 
// @filename: routers/user.ts
import { router, publicProcedure } from '../trpc';
import { z } from 'zod';
export const userRouter = router({
  userList: publicProcedure.query(() => {
    // [..]
    return [];
  }),
});
