# Dropbox

The `@uppy/dropbox` plugin lets users import files from their
[Dropbox](https://www.dropbox.com) account.

## When should I use this?

When you want to let users import files from their
[Dropbox](https://www.dropbox.com) account.

A [Companion](/docs/companion) instance is required for the Dropbox plugin to
work. Companion handles authentication with Dropbox, downloads the files, and
uploads them to the destination. This saves the user bandwidth, especially
helpful if they are on a mobile connection.

You can self-host Companion or get a hosted version with any
[Transloadit plan](https://transloadit.com/pricing/).

  <TabItem value="npm" label="NPM" default>

```shell
npm install @uppy/dropbox

```shell
yarn add @uppy/dropbox
```

  </TabItem>

  <TabItem value="cdn" label="CDN">
    <UppyCdnExample>
      {`
        import { Uppy, Dropbox } from "{{UPPY_JS_URL}}"
        const uppy = new Uppy()
        uppy.use(Dropbox, {
          // Options
        })
      `}
    </UppyCdnExample>
  </TabItem>
</Tabs>

## Use

Using Dropbox requires setup in both Uppy and Companion.

### Use in Uppy

```js {10-13} showLineNumbers
import Uppy from '@uppy/core';
import Dashboard from '@uppy/dashboard';
import Dropbox from '@uppy/dropbox';

import '@uppy/core/dist/style.min.css';
import '@uppy/dashboard/dist/style.min.css';

new Uppy().use(Dashboard, { inline: true, target: '#dashboard' }).use(Dropbox, {
	target: Dashboard,
	companionUrl: 'https://your-companion.com',
});
```

### Use in Companion

You can create a Dropbox App on the
[Dropbox Developers site](https://www.dropbox.com/developers/apps/create).

Things to note:

- Choose the “Dropbox API”, not the business variant.
- Typically you’ll want “Full Dropbox” access, unless you are absolutely certain
  that you need the other one.

You’ll be redirected to the app page. This page lists the app key and app
secret, which you should use to configure Companion as shown above.

The app page has a “Redirect URIs” field. Here, add:

```
https://$YOUR_COMPANION_HOST_NAME/dropbox/redirect
```

If you are using Transloadit hosted Companion:

```
https://api2.transloadit.com/companion/dropbox/redirect
```

You can only use the integration with your own account initially. Make sure to
apply for production status on the app page before you publish your app, or your
users will not be able to sign in!

Configure the Dropbox key and secret. With the standalone Companion server,
specify environment variables:

```shell
export COMPANION_DROPBOX_KEY="Dropbox API key"
export COMPANION_DROPBOX_SECRET="Dropbox API secret"
```

When using the Companion Node.js API, configure these options:

```js
companion.app({
	providerOptions: {
		dropbox: {
			key: 'Dropbox API key',
			secret: 'Dropbox API secret',
		},
	},
});
```

## API

### Options

#### `id`

A unique identifier for this plugin (`string`, default: `'Dropbox'`).

#### `title`

Title / name shown in the UI, such as Dashboard tabs (`string`, default:
`'Dropbox'`).

#### `target`

DOM element, CSS selector, or plugin to place the drag and drop area into
(`string` or `Element`, default: `null`).

#### `companionUrl`

URL to a [Companion](/docs/companion) instance (`string`, default: `null`).

#### `companionHeaders`

Custom headers that should be sent along to [Companion](/docs/companion) on
every request (`Object`, default: `{}`).

#### `companionAllowedHosts`

The valid and authorised URL(s) from which OAuth responses should be accepted
(`string` or `RegExp` or `Array`, default: `companionUrl`).

This value can be a `string`, a `RegExp` pattern, or an `Array` of both. This is
useful when you have your [Companion](/docs/companion) running on several hosts.
Otherwise, the default value should do fine.

#### `companionCookiesRule`

This option correlates to the
[RequestCredentials value](https://developer.mozilla.org/en-US/docs/Web/API/Request/credentials)
(`string`, default: `'same-origin'`).

This tells the plugin whether to send cookies to [Companion](/docs/companion).

#### `locale`

```js
export default {
	strings: {
		pluginNameDropbox: 'Dropbox',
	},
};
```
