React Unsplash Components

unsplash-react

React components to get unsplash images in your app!

Install

$ yarn add unsplash-react

Usage

Here's the most basic example:

import UnsplashReact, { Base64Uploader, withDefaultProps } from "unsplash-react"

const MY_ACCESS_KEY = "UNSPLASH_KEY_FROM_UNSPLASH"

export default function UnsplashUploader() {
  return (
    <UnsplashReact
      accessKey={MY_ACCESS_KEY}
      Uploader={withDefaultProps(Base64Uploader, { name: "event[logo]" })}
    />
  )
}

unsplash-react has two core steps

1. Find a photo from unsplash
2. Download the photo into the user's browser

Once the photo blob is in the browser, you can insert it into a page (using the URL), or upload the photo to your server for further use.

This is accomplished through the Uploader prop, which is a React component that is initialized with a standard set of props, and uses callbacks to signal its progress.

Please see the examples directory for more information, and don't hesitate to open an issue if you need help.

Try it out locally!

You'll need to create an application with Unsplash and get an access key to demo the components.

Once you have the access key, follow these steps.

$ git clone https://github.com/danielma/react-unsplash
$ cd react-unsplash
$ yarn
$ UNSPLASH_ACCESS_KEY=key yarn run dev
$ open http://localhost:10001/

Built-in Uploaders

There are examples of the 3 main uploaders in the examples directory.

BlobUploader

The BlobUploader downloads the selected unsplash photo, and calls onBloblLoaded with a Promise<Blob> representing the downloaded image.

Base64Uploader

The Base64Uploader downloads the selected unsplash photo as a blob, encodes it as base64, and inserts a <input type="hidden" /> with the encoded value for you to upload to your server.

DataTransferUploader (experimental)

The DataTransferUploader uses experimental APIs only available (as of writing) in Chrome to download the photo as a blob and set it as the value of a <input type="file" /> for uploading to your server.

ExternalLocationUploader

The ExternalLocationUploader downloads the selected unsplash photo, and then executes a POST request to uploadUrl. It then calls this.props.onFinishedUploading with the Promise<Response> of that request.

The key example usage for this is direct to S3 upload. You can provide and uploadUrl, and after the photo is uploaded, you can save the bucket URL on your server.

InsertIntoApplicationUploader

The InsertIntoApplicationUploader calls onFinishedUploading with the URL of the photo to download. This can be used to insert the photo directly into your application.
