Client library for communication with Companion. Intended for use in Uppy
plugins.

Uppy is being developed by the folks at [Transloadit](https://transloadit.com),
a versatile file encoding service.

## Example

```js
import Uppy from '@uppy/core'
import { Provider, RequestClient, Socket } from '@uppy/companion-client'

const uppy = new Uppy()

const client = new RequestClient(uppy, {
  companionUrl: 'https://uppy.mywebsite.com/',
})
client.get('/drive/list').then(() => {})

const provider = new Provider(uppy, {
  companionUrl: 'https://uppy.mywebsite.com/',
  provider: providerPluginInstance,
})
provider.checkAuth().then(() => {})

const socket = new Socket({ target: 'wss://uppy.mywebsite.com/' })
socket.on('progress', () => {})
```

## Installation

> Unless you are writing a custom provider plugin, you do not need to install
> this.
