RbSplash v1.0.0

RbSplash is a promise-based API wrapper for the popular Unsplash platform, written in Ruby and ported from wrapsplash (TypeScript). It uses concurrent-ruby for futures and Faraday for HTTP requests.

Unsplash provides beautiful high quality free images and photos that you can download and use for any project without any attribution.

Before using the Unsplash API, you need to register as a developer and read the API Guidelines.

Note: Every application must abide by the API Guidelines. Specifically, remember to hotlink images and trigger a download when appropriate.

Installation

Add this line to your application's Gemfile:

gem "rb_splash"

Then execute:

bundle install

Or install it directly:

gem install rb_splash

Sample Usage

require "rb_splash"

api = RbSplash::WrapSplashApi.new

# Initialize with a bearer token
api.init(bearer_token: ENV["UNSPLASH_BEARER_TOKEN"])

# Or initialize with access key credentials
api.init(
  access_key: ENV["UNSPLASH_ACCESS_KEY"],
  secret_key: ENV["UNSPLASH_SECRET_KEY"],
  redirect_uri: ENV["UNSPLASH_REDIRECT_URI"],
  code: ENV["UNSPLASH_AUTH_CODE"]
)

# Get the current user profile
profile = api.get_current_user_profile.value!

# Search for photos
results = api.search("nature", per_page: 5).value!

# Get a random photo
photo = api.get_random_photo(orientation: "landscape").value!

All API methods return a Concurrent::Promises::Future. Call .value! to get the result or raise on error.

Development

git clone https://github.com/SandeepVattapparambil/rb_splash.git
cd rb_splash
bundle install
bundle exec rspec

New API Aliases

The library includes more descriptive convenience methods such as get_photo, get_random_photo, create_collection, and update_collection. The original method names remain available for backward compatibility.

# Original names
api.get_a_photo("photo-id")
api.get_a_random_photo(orientation: "landscape")
api.create_new_collection("My Collection")
api.update_existing_collection("cid", "Title")

# Convenience aliases
api.get_photo("photo-id")
api.get_random_photo(orientation: "landscape")
api.create_collection("My Collection")
api.update_collection("cid", "Title")

Dependencies

This library depends on:

concurrent-ruby - for promise-based async futures
faraday - for HTTP requests
faraday-net_http - Net::HTTP adapter for Faraday

API Documentation

Schema

Location

The API base URL is https://api.unsplash.com/. Responses are sent as JSON.

Summary Objects

When retrieving a list of objects, an abbreviated or summary version of that object is returned - i.e., a subset of its attributes. To get a full detailed version of that object, fetch it individually.

Error Messages

If an error occurs, whether on the server or client side, the error message(s) will be returned in an errors array.

For example:

422 Unprocessable Entity

{
  "errors": ["Username is missing", "Password cannot be blank"]
}

Authorization

Public Actions

Many actions can be performed without requiring authentication from a specific user. For example, downloading a photo does not require a user to log in.

To authenticate requests in this way, pass your application's access key via the HTTP Authorization header:

Authorization: Client-ID YOUR_ACCESS_KEY

If only your access key is sent, attempting to perform non-public actions that require user authorization will result in a 401 Unauthorized response.

User Authentication

The Unsplash API uses OAuth2 to authenticate and authorize Unsplash users. Unsplash's OAuth2 paths live at https://unsplash.com/oauth/.

Before using RbSplash:

Developers are required to create a developer account from Unsplash.
Create a new App from Your Apps page.
Get the Access Key, Secret Key, Callback URLs, and Authorization code.
If you have a Bearer Token, then its super, or else you can generate it using RbSplash.

Note: Authorization code can be obtained by clicking the Authorize link next to Callback URLs. Also Authorization code is a one-time use code, you have to generate it again if the action fails!

RbSplash init()

The RbSplash instance has to be initialized with your credentials obtained from the Unsplash developer account for programmatic access. These credentials are passed to the init() function as options. The following example shows all the available options.

api.init(
  access_key: ENV['UNSPLASH_ACCESS_KEY'],
  secret_key: ENV['UNSPLASH_SECRET_KEY'],
  redirect_uri: ENV['UNSPLASH_REDIRECT_URI'],
  code: ENV['UNSPLASH_AUTH_CODE'],
  bearer_token: ENV['UNSPLASH_BEARER_TOKEN']
)

If you have a bearer_token, then only the bearer token has to be passed in.

api.init(bearer_token: ENV['UNSPLASH_BEARER_TOKEN'])

Generate Bearer Token

A method to generate a Bearer Token for write_access to private data. The init() method in this case requires access_key, secret_key, redirect_uri, and code.

Note: No parameters are required for this method.

api = RbSplash::WrapSplashApi.new

api.init(
  access_key: ENV['UNSPLASH_ACCESS_KEY'],
  secret_key: ENV['UNSPLASH_SECRET_KEY'],
  redirect_uri: ENV['UNSPLASH_REDIRECT_URI'],
  code: ENV['UNSPLASH_AUTH_CODE']
)

result = api.generate_bearer_token.value!
puts result

If successful, the response body will be a JSON representation of your user's access token a.k.a bearer token:

{
  "access_token": "091343ce13c8ae780065ecb3b13dc903475dd22cb78a05503c2e0c69c5e98044",
  "token_type": "bearer",
  "scope": "public read_photos write_photos",
  "created_at": 1436544465
}

And once you have your bearer_token you can use it in your app like this:

api.init(bearer_token: ENV['UNSPLASH_BEARER_TOKEN'])
