Gris

Gris is a framework for building opinionated Rack-based hypermedia APIs. Gris aims to provide useful generators, helpers and middleware common to API microservices. Note that Gris is in development and that the ground may shift.

It makes use of Grape, Roar, RSpec, Hyperclient, and Active Record with PostgreSQL among other excellent projects. Gris is derived from/inspired by the stellar and more sophisticated Napa framework by Bellycard Inc.. We stand on the shoulders of tall people.

Installation

Gris is available as a gem on rubygems, to install it run:

Caching

You can use caching by including this module in your ActiveRecord models,

class OfferEvent < ActiveRecord::Base
  include Gris::Caching
end

and then cache inside GET requests like this

offer_event =  OfferEvent.cached_find(id)

To expire the cache for an object, call

OfferEvent.expire_cache_for(id)

or, if you have an instance, use

offer_event.expire_cache

The name

Gris is named for the Cubist painter Juan Gris.
