A Ruby interface to the Yelp Developer API for searching local business information.

Yelpster

A Ruby object-oriented interface to the local business content available on Yelp at http://www.yelp.com. Functionality is provided to perform all searches available via the developer API including:

• search for business reviews by geo-bounding-box, geo-point, or address/location.
• search for a business review by business phone number.
• search for a neighborhood by geo-point or address/location.
• search for business details by geo-bounding-box, geo-point, or address/location.
• retrieval of business details by specifying yelp id of business

More detailed information on the underlying Yelp API, error response codes, and so forth is available at http://www.yelp.com/developers/getting_started.

This documentation is available at http://rubydoc.info/github/nvd/yelpster.

The latest source code is at http://github.com/nvd/yelpster.

Requirements

You must have a Yelp Web Service ID (YWSID) if you're using v1 of the api or Consumer Key, Consumer Secret, Token and a Token Secret for version 2. These are available at http://www.yelp.com/developers/getting_started/api_access.

You must conform to the Yelp Branding Requirements when making use of content retrieved via their API, documented at http://www.yelp.com/developers/getting_started/api_branding.

For tests to execute successfully you must have the YWSID (for v1) or YELP_CONSUMER_KEY, YELP_CONSUMER_SECRET, YELP_TOKEN and YELP_TOKEN_SECRET(for v2) set in your environment via (shell-dependent, bash example provided):

 % export YWSID='YOUR_ID_HERE'

or

 % export YELP_CONSUMER_KEY='YOUR_CONSUMER_KEY_HERE'
 % export YELP_CONSUMER_SECRET='YOUR_CONSUMER_SECRET_HERE'
 % export YELP_TOKEN='YOUR_TOKEN_HERE'
 % export YELP_TOKEN_SECRET='YOUR_TOKEN_SECRET_HERE'

Installing

 % gem install yelpster

Usage

Instantiate a Yelp::Client and use its search method to make requests of the Yelp server.

The available search request types are:

• Yelp::V1::Review::Request::BoundingBox
• Yelp::V1::Review::Request::GeoPoint
• Yelp::V1::Review::Request::Location
• Yelp::V1::Phone::Request::Number
• Yelp::V1::Neighborhood::Request::GeoPoint
• Yelp::V1::Neighborhood::Request::Location
• Yelp::V2::Business::Request::Id
• Yelp::V2::Search::Request::BoundingBox
• Yelp::V2::Search::Request::GeoPoint
• Yelp::V2::Search::Request::Location

You can include the overlying module to cut back on typing or in case of conflicts between classes, use the fully qualified search request class name.

By default, response content is formatted as a Ruby hash converted from Yelp's source JSON response content. Alternate response formats (including the original pure JSON) can be specified on request record construction via the Yelp::[V1/V2]::Request response_format parameter, available in all request record types.

One Time Client Configuration (Recommended)

To configure token/keys, add the following in a pre-loader file (eg: in initializers dir for Rails). Although currently available, support for specifying keys in request object will be deprecated in the future.

Yelp.configure(:yws_id          => 'YOUR_YWSID',
               :consumer_key    => 'YOUR_CONSUMER_KEY',
               :consumer_secret => 'YOUR_CONSUMER_SECRET',
               :token           => 'YOUR_TOKEN',
               :token_secret    => 'YOUR_TOKEN_SECRET')

Then create a client object (or use Yelp::Base.client) and call search method with the request object.

A few examples:

 # construct a client instance
 client = Yelp::Client.new

 include Yelp::V1::Review::Request
 # perform an address/location-based search for cream puffs nearby
 request = Location.new(
             :address => '650 Mission St',
             :city => 'San Francisco',
             :state => 'CA',
             :radius => 2,
             :term => 'cream puffs')
 response = client.search(request)

 # perform a location-based category search for either ice cream or donut shops in SF
 request = Location.new(
             :city => 'San Francisco',
             :state => 'CA',
             :category => ['donuts', 'icecream'])
 response = client.search(request)

 # perform a neighborhood name lookup for a specific geo-location point
 request = GeoPoint.new(
             :latitude => 37.782093,
             :longitude => -122.483230)
 response = client.search(request)

 # -------------------------------------------------------

 include Yelp::V1::Phone::Request
 # perform a business review search based on a business phone number
 request = Number.new(
             :phone_number => '4155551212')
 response = client.search(request)

 # -------------------------------------------------------

 include Yelp::V2::Business::Request
 # retrieve details of business vi yelp business id
 request = Id.new(
             :yelp_business_id => "pjb2WMwa0AfK3L-dWimO8w")
 response = client.search(request)

 # -------------------------------------------------------

 include Yelp::V2::Search::Request
 # search for businesses via bounding box geo coords'
 request = BoundingBox.new(
             :term => "cream puffs",
             :sw_latitude => 37.900000,
             :sw_longitude => -122.500000,
             :ne_latitude => 37.788022,
             :ne_longitude => -122.399797,
             :limit => 3)
 response = client.search(request)

 # search for businesses via lat/long geo point'
 request = GeoPoint.new(
             :term => "cream puffs",
             :latitude => 37.788022,
             :longitude => -122.399797)
 response = client.search(request)

 # search for businesses via location (address, neighbourhood, city, state, zip, country, latitude, longitude)'
 request = Location.new(
             :term => "cream puffs",
             :city => "San Francisco")
 response = client.search(request)

 request = Location.new(
             :term => "german food",
             :address => "Hayes",
             :latitude => 37.77493,
             :longitude => -122.419415)
 response = client.search(request)
