Openlibrary::Covers

A very small gem that wraps the OpenLibrary's Covers API (https://openlibrary.org/dev/docs/api/covers).

Note that OpenLibrary says that "a courtesy link back to Open Library is appreciated".

Installation

Add this line to your application's Gemfile:

gem 'openlibrary-covers'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install openlibrary-covers

Usage

require 'openlibrary/covers'
image = Openlibrary::Covers::Image.new '9780786965601'
image.found? # => true
image.url # => "http://covers.openlibrary.org/b/isbn/9780786965601-M.jpg"

image_by_oclc_number = Openlibrary::Covers::Image.new '798147823', :oclc
# Get a large image
image_by_oclc_number.url :L # => "http://covers.openlibrary.org/b/oclc/798147823-L.jpg"

invalid_image = Openlibrary::Covers::Image.new 'not-a-real-identifier'
invalid_image.found? # => false
invalid_image.url # => nil

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
