API Bee is a small client / spec for a particular style of JSON API.

These APIs must

  • Expose resource collections as paginated lists, with entries and paging properties.
  • Resource entities in collections must include an 'href' property pointing to the individual resource, so as to provide a degree of discoverability.

A single resource might look like:

  'name':        'Foo',
  'description': 'foo resoruce',
  'href':        ''

A resource collection looks like:

  'href': '',
  'total_entries': 100,
  'page': 1,
  'per_page': 10,
  'entries': [
      'name':        'Foo',
      'description': 'foo resoruce',
      'href':         ''
      'name':        'Bar',
      'description': 'bar resoruce',
      'href':        ''

Collection resources must include the fields 'href', 'total_entries', 'page', 'per_page' and 'entries'. This allows clients to paginate and fetch more pages.


It is up to individual adapters to talk to different services, handle auth, etc. An adapter must at least implement 'get' for read-only APIs.

class ApiBee::Adapters::Special
  def get(path, options = {})
    # fetch JSON from remote API, passing pagination options if available

The use it:

api = ApiBee.setup :special, optional_custom_data

api.get('/my/resources').each do |r|

Delegate to adapter

Lazy-loading and paginating resources is great for GET requests, but you might want to still use your adapter's other methods.

api = ApiBee.setup(MyCustomAdapter) do |config|
  config.expose :delete, :post

# This still wraps your adapter's get() method and adds lazy-loading and pagination

# This delegates directory to MyCustomAdapter#post()'/products', :title => 'Foo', :price => 100.0)

finding a single resource

There's a special get_one method that you can call on lists. It delegates to the adapter and it's useful for finding a single resource in the context of a paginated list.

resources = api.get('/my/resources')
resource = resources.get_one('foobar')

That delegates to Adapter#get_one passing 2 arguments: the list's href and the passed name or identifier, so:

class ApiBee::Adapters::Special
  # ...
  def get_one(href, id)
    get "#{href}/#{id}"

Lazy loading

ApiBee wraps your adapters in lazy-loading objects. API calls will only be issued when accessing or iterating data.

The 'href' property in entities will be used to load more data. For example:

# /resources
    'title': 'Foo bar',
    'href': '/resources/foo-bar'

# /resources/foo-bar
  'title': 'Foo bar',
  'description': 'Foo description'
api = ApiBee.get(:some_adapter)

resources = api.get('/resources') # no API call is made

resource = resources.first # call to /resources is made

resource['title'] # => 'Foo bar', title data available

resource['description'] # => 'Foo description'. Makes internal new request to /resources/foo-bar

Hash adapter

ApiBee ships with an in-memory Hash adapter so it can be use with test/local data (for example a YAML file).

api = ApiBee.setup(:hash, YAML.load_file('./my_data.yml'))

products = api.get('/products') # => ApiBee::Node::List

products.first # => ApiBee::Node::Single

products.each() # iterate current page

products.current_page # => 1

products.paginate(:page => 2, :per_page => 4) # => ApiBee::Node::List # Next page

products.has_next_page? # => false

products.has_prev_page? # => true

products.prev_page # => 1


See examples/github_api.rb for an adapter that paginates Github's API by decorating it's results with ApiBee's required pagination properties
