SquareLite

Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/square/lite. To experiment with that code, run bin/console for an interactive prompt.

TODO: Delete this and the text above, and describe your gem

Installation

Add this line to your application's Gemfile:

gem 'square-lite'

Usage

Basic Usage:

require 'square-lite'

# override default configuration if desired
SquareLite.configure do |config|
  config.logger = Rails.logger # Logger.new(STDOUT)
  config.timeout = 10
end

# search for an item
SquareLite.client.search(for: :item).id('SQUARE_ITEM_ID').map { ... }

Typhoeus Configuratio

Typhoeus has global configuration and per request configuration.

Barebones Client

SquareLite::GenericClient provides a simple interface to wrap standard headers and access token to build a Typhoeus::Request.

Authorization

Currently limited to using an access token. The gem will pull this from the environment variable SQUARE_ACCESS_TOKEN or it can be set when constructing the client instance: SquareClient.client(access_token: 'TOKEN')

Searching

Currently, only the catalog related objects are searchable.

• run: Returns an enumerator that handles pagination.
• fetch!: Loads all data
• search: Entry point for search query. Takes for: a_type or for: [:type1, :type2]
• for: Specify the type via method instead of in the search method.
• id: takes 1+ identifies
• all: lists all items in the catalog
• starts_with(attr_name: :pre): matches attr_name with values such as prefix and prehistoric
• excactly(attr_name: :value): Exact match of attribute name.
• within(attr_name: start_val..end_val): Finds matches for within the range. -Infinity and Infinity can be used.
• at_most(attr_name: value): Inclusive match where everything less than or equal is returned.
• at_least(attr_name: value): Inclusive match where everything greater than or equal is returned.
• ordered(attr_name: :asc): Sorts records based on attr_name, either ASC or DESC. Can be invoked as ordered(attr_name) and defaults to DESC.
• limit(num): Request only num records to be returned. Square doesn't promise they won't return more, I think.
• since(1.day.ago): Returns only objects that have been modified since specified time.
• with_deleted: Allows catalog queries to return back deleted objects. Does not work for id or all.
• with_related: Returns assocaiated objects of other types with the matching records.

Pagination

If the result set is too big, Square will paginate the data.

SquareLite::GenericClient.paginate will build the generic client in a way that handles pagination of the pages lazily. SquareLite::Client uses GenericClient.paginate. Additionally, request data for the request is cached locally in memory so additional iteration over the cursor will not incur additional network requests.

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.
