Uppy 4.0 is here: TypeScript rewrite, Google Photos, React hooks, and much more.

Unsplash

The @uppy/unsplash plugin lets users import files from their Unsplash account.

tip

Try out the live example or take it for a spin in StackBlitz.

When should I use this?​

When you want to let users import files from their Unsplash account.

A Companion instance is required for the Unsplash plugin to work. Companion handles authentication with Unsplash, 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.

npm install @uppy/unsplash

Use​

Using Unsplash requires setup in both Uppy and Companion.

Use in Uppy​

import Uppy from '@uppy/core';
import Dashboard from '@uppy/dashboard';
import Unsplash from '@uppy/unsplash';

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

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

Use with Transloadit​

import { COMPANION_URL, COMPANION_ALLOWED_HOSTS } from '@uppy/transloadit';
import Unsplash from '@uppy/unsplash';

uppy.use(Unsplash, {
	companionUrl: COMPANION_URL,
	companionAllowedHosts: COMPANION_ALLOWED_HOSTS,
});

You may also hit rate limits, because the OAuth application is shared between everyone using Transloadit.

To solve that, you can use your own OAuth keys with Transloadit’s hosted Companion servers by using Transloadit Template Credentials. Create a Template Credential on the Transloadit site. Select “Companion OAuth” for the service, and enter the key and secret for the provider you want to use. Then you can pass the name of the new credentials to that provider:

import { COMPANION_URL, COMPANION_ALLOWED_HOSTS } from '@uppy/transloadit';
import Unsplash from '@uppy/unsplash';

uppy.use(Unsplash, {
	companionUrl: COMPANION_URL,
	companionAllowedHosts: COMPANION_ALLOWED_HOSTS,
	companionKeysParams: {
		key: 'YOUR_TRANSLOADIT_API_KEY',
		credentialsName: 'my_companion_dropbox_creds',
	},
});

Use in Companion​

You can create a Unsplash App on the Unsplash Developers site. You’ll be redirected to the app page, this page lists the app key and app secret.

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

export COMPANION_UNSPLASH_KEY="Unsplash API key"
export COMPANION_UNSPLASH_SECRET="Unsplash API secret"

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

companion.app({
	providerOptions: {
		unsplash: {
			key: 'Unsplash API key',
			secret: 'Unsplash API secret',
		},
	},
});

API​

Options​

id​

A unique identifier for this plugin (string, default is a unique ID for each plugin).

title​

Title / name shown in the UI, such as Dashboard tabs (string, default is the name of the plugin).

target​

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

companionUrl​

URL to a Companion instance (string, default: null).

companionHeaders​

Custom headers that should be sent along to 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). This option is useful when you have your Companion running on several hosts. Otherwise, the default value should do fine, which uses the origin of companionUrl.

This value can be a string, a RegExp pattern, or an Array of these. Strings are evaluated as regular expressions too and will be wrapped in a RegExp like so:

new RegExp(`^${value}$`);

Important: You must escape regex characters like ., or you might open your app up to security vulnerabilities.

  • Example correct strings
    • '^(?:.*\\.)?example\.com$' matches example.com and all of its subdomains.
    • 'https://example\.com' matches https://example.com only.
  • Example vulnerability: 'https://www.example.com' would allow an attacker with the domain wwwxexample.com to forge and inject a fraudulent token into Uppy.

companionCookiesRule​

This option correlates to the RequestCredentials value (string, default: 'same-origin').

This tells the plugin whether to send cookies to Companion.

locale​

An object with strings property containing additional i18n strings. The key is the i18n key and the value is the English string.

Example:

{
	strings: {
		someKey: 'Some English string',
	},
}

storage​

A custom storage to be used for the plugin’s persistent data. Type AsyncStore, default is LocalStorage.
