Nuxt automatically scans files inside the `~/server/api`, `~/server/routes`, and `~/server/middleware` directories to register API and server handlers with HMR support. Nuxt automatically scans files inside these directories to register API and server handlers with HMR support:
- `~/server/api`
- `~/server/routes`
- `~/server/middleware`
Each file should export a default function defined with `defineEventHandler()`. Each file should export a default function defined with `defineEventHandler()` or `eventHandler()` (alias).
The handler can directly return JSON data, a `Promise` or use `event.node.res.end()` to send response. The handler can directly return JSON data, a `Promise` or use `event.node.res.end()` to send a response.

::
## Example
Create a new file in `server/api/hello.ts`:
```ts [server/api/hello.ts] ```ts [server/api/hello.ts]
export default defineEventHandler((event) => { export default defineEventHandler((event) => {
return { return {
api: 'works' hello: 'world'
} }
}) })
``` ```
You can now universally call this API using `await $fetch('/api/hello')`. You can now universally call this API in your pages and components:
```vue [pages/index.vue]
<script setup>
const { data } = await useFetch('/api/hello')
</script>
<template>
<pre>{{ data }}</pre>
</template>
```
Note that [h3 utilities](https://github.com/unjs/h3#utilities) are auto-imported.

## Server Routes ## Server Routes
Files inside the `~/server/api` are automatically prefixed with `/api` in their route. Files inside the `~/server/api` are automatically prefixed with `/api` in their route.
For adding server routes without `/api` prefix, you can instead put them into `~/server/routes` directory.

## Server Utilities ## Server Utilities
Server routes are powered by [unjs/h3](https://github.com/unjs/h3) which comes with a handy set of helpers. Server routes are powered by [unjs/h3](https://github.com/unjs/h3) which comes with a handy set of helpers.

You can add more helpers yourself inside the `~/server/utils` directory. You can add more helpers yourself inside the `~/server/utils` directory.
## Server Types
::alert{type="info"}
This feature is available from Nuxt >= 3.5
::
To improve clarity within your IDE between the auto-imports from 'nitro' and 'vue', you can add a `~/server/tsconfig.json` with the following content:
```json [server/tsconfig.json]
{
"extends": "../.nuxt/tsconfig.server.json"
}
```
Although right now these values won't be respected when type checking (`nuxi typecheck`), you should get better type hints in your IDE.
