Supercast Ruby Library

The Supercast Ruby library provides convenient access to the Supercast API from applications written in the Ruby language. It includes a pre-defined set of classes for API resources that initialize themselves dynamically from API responses.

The library also provides other features. For example:

• Easy configuration path for fast setup and use.
• Helpers for pagination.
• Tracking of "fresh" values in API resources so that partial updates can be executed.
• Built-in mechanisms for the serialization of parameters according to the expectations of Supercast's API.

Documentation

See the API docs.

Installation

You don't need this source code unless you want to modify the gem. If you just want to use the package, just run:

gem install supercast

If you want to build the gem from source:

gem build supercast.gemspec

Requirements

• Ruby 2.1+.

Bundler

If you are installing via bundler, you should be sure to use the https rubygems source in your Gemfile, as any gems fetched over http could potentially be compromised in transit and alter the code of gems fetched securely over https:

source 'https://rubygems.org'

gem 'rails'
gem 'supercast'

Usage

The library needs to be configured with your channels's client secret which is available in your Supercast Dashboard. Set Supercast.api_key to its value:

require 'supercast'

Supercast.api_key = "123abc..."

# list subscribers
Supercast::Subscriber.list()

# retrieve single episode
Supercast::Episode.retrieve(1)

Here are the methods available to use:

Supercast::Channel

• Supercast::Channel.save(id, params) Updates a Channel by ID.

Supercast::Creator

• Supercast::Creator.list() Lists all the Creators on the authenticated Channel.
• Supercast::Creator.save(id, params) Updates a Creator by UUID or Email.
• Supercast::Creator.destroy(id) Destroys a Creator by UUID or Email.

Supercast::Episode

• Supercast::Episode.list() Lists all the Episodes on the authenticated Channel.
• Supercast::Episode.create(params) Create a new Episode on the authenticated Channel.
• Supercast::Episode.save(id, params) Updates an Episode by ID.
• Supercast::Episode.destroy(id) Destroys an Episode by ID.

Supercast::Feeds

• Supercast::Feeds.activate(id) Activate a the feeds of a subscriber by UUID or Email.
• Supercast::Feeds.suspend(id) Activate a the feeds of a subscriber by UUID or Email.
• Supercast::Feeds.deactivate(id) Activate a the feeds of a subscriber by UUID or Email.

Supercast::Role

• Supercast::Role.list() Lists all the Roles on the authenticated Channel.
• Supercast::Role.create(params) Create a new Role on the authenticated Channel.
• Supercast::Role.save(id, params) Updates a Role by ID.
• Supercast::Role.destroy(id) Destroys a Role by ID.

Supercast::Subscriber

• Supercast::Subscriber.list() Lists all the Subscribers on the authenticated Channel.
• Supercast::Subscriber.create(params) Create a new Subscriber on the authenticated Channel.
• Supercast::Subscriber.save(id, params) Updates a Subscriber by UUID or Email.
• Supercast::Subscriber.destroy(id) Destroys a Subscriber by UUID or Email.

Supercast::UsageAlert

• Supercast::UsageAlert.list() Lists all the Subscribers on the authenticated Channel.
• Supercast::UsageAlert.dismiss(params) Dismiss the Usage Alert.
• Supercast::UsageAlert.ignore(params) Ignore further Usage Alerts from this user.
• Supercast::UsageAlert.suspend(params) Suspend the user associated with the Usage Alert.

Configuring a Client

While a default HTTP client is used by default, it's also possible to have the library use any client supported by [Faraday][faraday] by initializing a Supercast::Client object and giving it a connection:

conn = Faraday.new
client = Supercast::Client.new(conn)
episode, resp = client.request do
  Supercast::Episode.retrieve(1)
end
puts resp.data

Configuring a proxy

A proxy can be configured with Supercast.proxy:

Supercast.proxy = "https://user:pass@example.com:1234"

Configuring an API Version

By default, the library will use the latest API version. This can be overridden with this global option:

Supercast.api_version = 'v2'

See versioning in the API reference for more information.

Configuring CA Bundles

By default, the library will use its own internal bundle of known CA certificates, but it's possible to configure your own:

Supercast.ca_bundle_path = "path/to/ca/bundle"

Configuring Automatic Retries

The library can be configured to automatically retry requests that fail due to an intermittent network problem:

Supercast.max_network_retries = 2

[Idempotency keys][idempotency-keys] are added to requests to guarantee that retries are safe.

Configuring Timeouts

Open and read timeouts are configurable:

Supercast.open_timeout = 30 // in seconds
Supercast.read_timeout = 80

Please take care to set conservative read timeouts. Some API requests can take some time, and a short timeout increases the likelihood of a problem within our servers.

Logging

The library can be configured to emit logging that will give you better insight into what it's doing. The info logging level is usually most appropriate for production use, but debug is also available for more verbosity.

There are a few options for enabling it:

1. Set the environment variable SUPERCAST_LOG to the value debug or info:

   $ export SUPERCAST_LOG=info

2. Set Supercast.log_level:

   Supercast.log_level = Supercast::LEVEL_INFO

Development

Run the linter:

rubocop

Update bundled CA certificates from the [Mozilla cURL release][curl]:

bundle exec rake update_certs
