# detectMulterUpload

**Kind:** Function

**Source:** [`atloria-monorepo/libs/parser-core/src/openapi/multipart.ts`](https://github.com/sherkety/atloria/blob/main/atloria-monorepo/libs/parser-core/src/openapi/multipart.ts#L212)

Express/multer: `upload.single('avatar')` in a route's middleware position.

Pass ONLY the middleware argument slices — a whole route call would drag an inline handler
body in with it, where an unrelated `.any(` or `.array(` would read as an upload.

## Signature

```ts
function detectMulterUpload(middleware: string): MultipartBody | undefined
```

## Parameters

| Name | Type |
|---|---|
| `middleware` | `string` |

**Returns:** `MultipartBody | undefined`
