+
+# Simple Usage
+
+## 1. Create a tRPC router
+
+Initialize your tRPC backend using the `initTRPC` function and create your first router.
+
+::code-group
+
+```ts [server/trpc/trpc.ts]
+/**
+ * This is your entry point to setup the root configuration for tRPC on the server.
+ * - `initTRPC` should only be used once per app.
+ * - We export only the functionality that we use so we can enforce which base procedures should be used
+ *
+ * Learn how to create protected base procedures and other things below:
+ * @see https://trpc.io/docs/v10/router
+ * @see https://trpc.io/docs/v10/procedures
+ */
+import { initTRPC } from '@trpc/server'
+
+const t = initTRPC.create()
+
+/**
+ * Unprotected procedure
+ **/
+export const publicProcedure = t.procedure;
+
+export const router = t.router;
+export const middleware = t.middleware;
+```
+
+```ts [server/api/trpc/[trpc].ts]
+/**
+ * This is the API-handler of your app that contains all your API routes.
+ * On a bigger app, you will probably want to split this file up into multiple files.
+ */
+import { createNuxtApiHandler } from 'trpc-nuxt'
+import { publicProcedure, router } from '~/server/trpc/trpc'
+import { z } from 'zod'
+
+export const appRouter = router({
+  hello: publicProcedure
+    // This is the input schema of your procedure
+    .input(
+      z.object({
+        text: z.string().nullish(),
+      }),
+    )
+    .query(({ input }) => {
+      // This is what you're returning to your client
+      return {
+        greeting: `hello ${input?.text ?? 'world'}`,
+      }
+    }),
+})
+
+// export only the type definition of the API
+// None of the actual implementation is exposed to the client
+export type AppRouter = typeof appRouter;
+
+// export API handler
+export default createNuxtApiHandler({
+  router: appRouter,
+  createContext: () => ({}),
+})
+```
+
+::
+
+## 2. Create tRPC client plugin
+
+Create a strongly-typed plugin using your API's type signature.
+
+```ts [plugins/client.ts]
+import { createTRPCNuxtClient, httpBatchLink } from 'trpc-nuxt/client'
+import type { AppRouter } from '~/server/api/trpc/[trpc]'
+
+export default defineNuxtPlugin(() => {
+  /**
+   * createTRPCNuxtClient adds a `useQuery` composable
+   * built on top of `useAsyncData`.
+   */
+  const client = createTRPCNuxtClient<AppRouter>({
+    links: [
+      httpBatchLink({
+        url: '/api/trpc',
+      }),
+    ],
+  })
+
+  return {
+    provide: {
+      client,
+    },
+  }
+})
+```
+
+## 3. Make an API request
+
+```vue [pages/index.vue]
+<script setup lang="ts">
+const { $client } = useNuxtApp()
+
+const { data: hello } = await $client.hello.useQuery({ text: 'client' })
+</script>
+
+<template>
+  <div>
+    <p>{{ hello?.greeting }}</p>
+  </div>
+</template>
+```

+
+# Nuxt client
+
+The magic of tRPC is making strongly typed API calls without relying on code generation. With full-stack TypeScript projects, you can directly import types from the server into the client! This is a vital part of how tRPC works.
+
+## Initialize a tRPC client
+
+Create a typesafe client via a Nuxt [plugin](https://nuxt.com/docs/guide/directory-structure/plugins) with the `createTRPCNuxtClient` method from `trpc-nuxt/client`, and add a `links` array with a [terminating link](https://trpc.io/docs/links#the-terminating-link). If you want to learn more about tRPC links, check out the docs [here](https://trpc.io/docs/links):
+
+::alert{type="info"}
+`createTRPCNuxtClient` extends [createTRPCProxyClient](https://trpc.io/docs/vanilla#initialize-a-trpc-client) and adds a `useQuery` method built on top of [useAsyncData](https://nuxt.com/docs/api/composables/use-async-data).
+::
+
+```ts [plugins/client.ts]
+import { createTRPCNuxtClient, httpBatchLink } from 'trpc-nuxt/client'
+import type { AppRouter } from '~/server/trpc/routers'
+
+export default defineNuxtPlugin(() => {
+  const client = createTRPCNuxtClient<AppRouter>({
+    links: [
+      httpBatchLink({
+        url: '/api/trpc',
+      }),
+    ],
+  })
+
+  return {
+    provide: {
+      client,
+    },
+  }
+})
+```
+
+As you can see, we passed `AppRouter` as a type argument of `createTRPCNuxtClient`. This returns a strongly typed `client` instance, a proxy that mirrors the structure of your `AppRouter` on the client:
+
+```vue [pages/index.vue]
+<script setup lang="ts">
+const { $client } = useNuxtApp()
+
+const getUser = await $client.getUser.useQuery('id_bilbo');
+// => { data: { id: 'id_bilbo', name: 'Bilbo' }, pending: false, error: false };
+
+const bilbo = await $client.getUser.query('id_bilbo');
+// => { id: 'id_bilbo', name: 'Bilbo' };
+const frodo = await $client.createUser.mutate({ name: 'Frodo' });
+// => { id: 'id_frodo', name: 'Frodo' };
+</script>
+```

+# HTTP Link
+
+`httpLink` is a [terminating link](https://trpc.io/docs/links#the-terminating-link) that sends a tRPC operation to a tRPC procedure over HTTP.
+
+`httpLink` supports both POST and GET requests.
+

It also sets the default headers using [`useRequestHeaders`](https://nuxt.com/docs/api/composables/use-request-headers#userequestheaders).
+::
+
+## Usage
+
+You can import and add the `httpLink` to the `links` array as such:
+
+```ts
+import { createTRPCNuxtClient, httpLink } from 'trpc-nuxt/client'
+import type { AppRouter } from '~/server/trpc/routers'

+```ts
+export interface HTTPLinkOptions {

+   * Select headers to pass to `useRequestHeaders`.
+   */

+  /**

+  AbortController?: typeof AbortController | null;
+  /**
+   * Headers to be set on outgoing requests or a callback that of said headers
+   * @link http://trpc.io/docs/v10/header

+# HTTP Batch Link
+

+

+  links: [
+    httpBatchLink({
+      url: '/api/trpc',
+    }),
+  ],
+})
+```
+
+After that, you can make use of batching by setting all your procedures in a `Promise.all`. The code below will produce exactly one HTTP request and on the server exactly `one` database query:
+
+```ts
+const somePosts = await Promise.all([
+  $client.post.byId.query(1);
+  $client.post.byId.query(2);
+  $client.post.byId.query(3);
+])
+```
+
+## `httpBatchLink` Options
+
+The `httpBatchLink` function takes an options object that has the `HTTPBatchLinkOptions` shape.
+
+```ts
+export interface HttpBatchLinkOptions extends HTTPLinkOptions {
+  maxURLLength?: number;
+}
+
+export interface HTTPLinkOptions {
+  url: string;
+  /**
+   * Select headers to pass to `useRequestHeaders`.
+   */
+  pickHeaders?: string[];
+  /**
+   * Add ponyfill for fetch.
+   */
+  fetch?: typeof fetch;
+  /**
+   * Add ponyfill for AbortController
+   */
+  AbortController?: typeof AbortController | null;
+  /**
+   * Headers to be set on outgoing requests or a callback that of said headers
+   * @link http://trpc.io/docs/v10/header
+   */
+  headers?: HTTPHeaders | (() => HTTPHeaders | Promise<HTTPHeaders>);
+}
+```
+
+## Setting a maximum URL length
+
+When sending batch requests, sometimes the URL can become too large causing HTTP errors like [413 Payload Too Large](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/413), [414 URI Too Long](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/414), and [404 Not Found](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/404). The `maxURLLength` option will limit the number of requests that can be sent together in a batch.
+
+```ts
+import { createTRPCNuxtClient, httpBatchLink } from 'trpc-nuxt/client';
+import type { AppRouter } from '~/server/trpc/routers'
+
+const client = createTRPCNuxtClient<AppRouter>({
+  links: [
+    httpBatchLink({
+      url: '/api/trpc',
+      maxURLLength: 2083, // a suitable size
+    }),
+  ],
+});
