 ### File upload aliases
 API Gateway has implemented file uploads. You can upload files as a multipart form data (thanks to [busboy](https://github.com/mscdex/busboy) library) or as a raw request body. In both cases, the file is transferred to an action as a `Stream`. In multipart form data mode you can upload multiple files, as well.

-Please note, you have to disable other body parsers in order to accept files.

 In order to access the files passed by multipart-form these specific fields can be used inside the action:
 - `ctx.params` is the Readable stream containing the file passed to the endpoint
-- `ctx.params.$params` parameters from URL querystring
-- `ctx.meta.$multipart` contains the additional text form-data fields passed _before other files fields_.

 ### Auto-alias
 The auto-alias feature allows you to declare your route alias directly in your services. The gateway will dynamically build the full routes from service schema.
