-[![Version](https://img.shields.io/npm/v/trpc-nuxt?style=flat&colorA=000000&colorB=000000)](https://www.npmjs.com/package/trpc-nuxt)
-
-End-to-end typesafe APIs with [tRPC.io](https://trpc.io/) in Nuxt applications.
-
-<p align="center">

-    <figcaption>
-      <p align="center">
-        The client above is <strong>not</strong> importing any code from the server, only its type declarations.
-      </p>
-    </figcaption>
-  </figure>
-</p>
-
-## Install
-
-```bash
-npm i trpc-nuxt
-```
-
-```ts
-// nuxt.config.ts
-import { defineNuxtConfig } from 'nuxt'
-
-export default defineNuxtConfig({
-  modules: ['trpc-nuxt'],
-  trpc: {
-    baseURL: 'http://localhost:3000', // defaults to http://localhost:3000
-    endpoint: '/trpc', // defaults to /trpc
-  },
-  typescript: {
-    strict: true // required to make input/output types work
-  }
-})
-```
-
-## Usage
-
-Expose your tRPC [routes](https://trpc.io/docs/router) under `~/server/trpc/index.ts`:
-
-```ts
-// ~/server/trpc/index.ts
-import type { inferAsyncReturnType } from '@trpc/server'
-import * as trpc from '@trpc/server'
-import { z } from 'zod' //  yup/superstruct/zod/myzod/custom
-
-export const router = trpc.router()
-  // queries and mutations...
-  .query('getUsers', {
-    async resolve(req) {
-      // use your ORM of choice
-      return await UserModel.all()
-    },
-  })
-  .mutation('createUser', {
-    // validate input with Zod
-    input: z.object({ name: z.string().min(5) }),
-    async resolve(req) {
-      // use your ORM of choice
-      return await UserModel.create({
-        data: req.input,
-      })
-    },
-  })
-```
-
-Use the client like so:
-
-```ts
-const client = useClient() // auto-imported
-
-const users = await client.query('getUsers')
-
-const newUser = await client.mutation('createUser', {
-  name: 'wagmi'
-})
-```
-
-## useAsyncQuery
-
-A thin wrapper around [`useAsyncData`](https://v3.nuxtjs.org/api/composables/use-async-data/) and `client.query()`.
-
-The first argument is a `[path, input]`-tuple - if the `input` is optional, you can omit the, `input`-part.
-
-You'll notice that you get autocompletion on the `path` and automatic typesafety on the `input`.
-
-```ts
-const {
-  data,
-  pending,
-  error,
-  refresh
-} = await useAsyncQuery(['getUser', { id: 69 }], {
-  // pass useAsyncData options here
-  lazy: false
-})
-```
-
-## useClientHeaders
-
-A composable that lets you add additional properties to pass to the tRPC Client. It uses `useStorage` from [@vueuse/core](https://vueuse.org/core/usestorage).
-
-```ts
-const headers = useClientHeaders()
-
-const { data: token } = await useAsyncQuery(['auth.login', { username, password }])
-
-headers.value.Authorization = `Bearer ${token}`
-
-// All client calls will now include the Authorization header.
-// For SSR, please follow this link https://github.com/trpc/trpc/discussions/1686
-```
-
-## Options
-
-trpc-nuxt accepts the following options exposed under `~/server/trpc/index.ts`:
-
-```ts
-import * as trpc from '@trpc/server'
-import type { inferAsyncReturnType } from '@trpc/server'
-import type { CompatibilityEvent } from 'h3'
-import type { OnErrorPayload } from 'trpc-nuxt/api'
-
-export const router = trpc.router<inferAsyncReturnType<typeof createContext>>()
-
-// Optional
-// https://trpc.io/docs/context
-export const createContext = (event: CompatibilityEvent) => {
-  // ...
-  return {
-    /** context data */
-  }
-}
-
-// Optional
-// https://trpc.io/docs/caching#using-responsemeta--to-cache-responses
-export const responseMeta = () => {
-  // ...
-  return {
-    // { headers: ... }
-  }
-}
-
-// Optional
-// https://trpc.io/docs/error-handling#handling-errors
-export const onError = (payload: OnErrorPayload<typeof router>) => {
-  // Do whatever here like send to bug reporting and stuff
-}
-```

-            ? error.cause.flatten()
-            : null,

-### Output Validation
-
-```ts
-// ~/server/trpc/index.ts
-import { z } from 'zod'
-
-export const router = trpc
-  .router()
-  .query('hello', {
-    // validate output with Zod
-    output: z.object({
-      greeting: z.string()
-    }),
-    // expects return type of { greeting: string }
-    resolve() {
-      return {
-        greeting: 'hello!',
-      }
-    },
-  })
-```
