-# @uppy/companion-client

-## 5.1.1
-
-### Patch Changes
-
-- 0c16fe4: - Split UppyFile into two intefaces distinguished by the `isRemote` boolean:
-  - LocalUppyFile
-  - RemoteUppyFile
-- Updated dependencies [0c16fe4]
-  - @uppy/core@5.1.1
-  - @uppy/utils@7.1.1
-
-## 5.1.0
-
-### Minor Changes
-
-- 5ba2c1c: Introduce the concept of server-side search and add support for it for the Dropbox provider. Previously, only client-side filtering in the currently viewed folder was possible, which was limiting. Now users using Companion with Dropbox can perform a search across their entire account.

-
-- 975317d: Removed "main" from package.json, since export maps serve as the contract for the public API.
-- Updated dependencies [4b6a76c]

-## 5.0.0
-
-### Major Changes
-
-- c5b51f6: ### Export maps for all packages
-
-  All packages now have export maps. This is a breaking change in two cases:
-
-  1. The css imports have changed from `@uppy[package]/dist/styles.min.css` to `@uppy[package]/css/styles.min.css`
-  2. You were importing something that wasn't exported from the root, for instance `@uppy/core/lib/foo.js`. You can now only import things we explicitly exported.
-
-  #### Changed imports for `@uppy/react`, `@uppy/vue`, and `@uppy/svelte`
-
-  Some components, like Dashboard, require a peer dependency to work but since all components were exported from a single file you were forced to install all peer dependencies. Even if you never imported, for instance, the status bar component.
-
-  Every component that requires a peer dependency has now been moved to a subpath, such as `@uppy/react/dashboard`, so you only need to install the peer dependencies you need.
-
-  **Example for `@uppy/react`:**
-
-  **Before:**
-
-  ```javascript
-  import { Dashboard, StatusBar } from "@uppy/react";
-  ```
-
-  **Now:**
-
-  ```javascript
-  import Dashboard from "@uppy/react/dashboard";
-  import StatusBar from "@uppy/react/status-bar";
-  ```

-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.
-
-```bash
-$ npm install @uppy/companion-client
-```
-
-## Documentation
-
-Documentation for this plugin can be found on the
-[Uppy website](https://uppy.io/docs/companion).
