RestfulResource

Provides an ActiveResource like interface to JSON API's

Caching using faraday-http-cache

Enabled by passing an initialsed cache object (eg Rails.cache)

RestfulResource::Base.configure(
  base_url: "http://my.api.com/",
  cache_store: Rails.cache
)

To make requests that bypass the local HTTP cache use the no_cache: true option eg:

Object.find(1, no_cache: true)

Http requests are automatically instrumented using ActiveSupport::Notifications

A Metrics class can be provided that RestfulResource will use to emit metrics. This class needs to respond to count, sample, measure methods.

eg

RestfulResource::Base.configure(
  base_url: "http://my.api.com/",
  instrumentation: {
    metric_class: Metrics,  # Required
    app_name: 'rails_site', # Required
    api_name: 'api'         # Optional, defaults to 'api'
  }
)

Where the Metrics class has in interface like:

class Metrics
  module_function

  def count(name, i)
  end

  def sample(name, i)
  end

  def measure(name, i)
  end
end

This will call the methods on the Metrics class with:

Metrics.measure('rails_site.api.time', 215.161237) # Time taken
Metrics.sample('rails_site.api.status', 200) # HTTP status code
Metrics.count('rails_site.api.called, 1)

Note: To customize the names we can specify :app_name and :api_name options to RestfulResource::Base.configure

Enable Http caching:

RestfulResource::Base.configure(
  base_url: "http://my.api.com/",
  cache_store: Rails.cache,
  instrumentation: {
    metric_class: Metrics,
    app_name: 'rails_site',
    api_name: 'api'
  }
)

This will call the methods on the Metrics class with:

Metrics.sample('rails_site.api.cache_hit', 1) # When a request is served from the cache
Metrics.sample('rails_site.api.cache_miss', 1) # When a request is fetched from the remote API
Metrics.sample('rails_site.api.cache_bypass', 1) # When a request did not go through the cache at all

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

1. Amend the version.rb to your desired version on your Pull Request & get it merged
2. Pull latest main & create a matching tag e.g.: git tag -a v2.15.0 -m "Bump Faraday to a minimum 1.10"
3. Push the tag e.g.: git push origin v2.15.0
4. Run bundle exec rake release
   • You'll need to authenticate with RubyGems, the credentials are in Bitwarden

• Test that has_many and has_one pick correct class for children (if defined)
• Make base_url resilient when missing trailing slash
• Implement http authentication
