grape-cors

Adds (simple) support for Cross Origin requests to grape - this is particular useful if you want to host a Swagger UI explorer on a different domain.

Right now this module only supports a single host (or the '*' wildcard) and GET requests only. PUT/POST support works for Safari and Chrome. The list of allowed headers is hardcoded to be origin, content-type, accept at the moment

Installation

Add this line to your application's Gemfile:

gem 'grape-cors'

And then execute:

$ bundle

Or install it yourself as:

$ gem install grape-cors

Usage

Add allow_cross_domain_request_from '*' to your Grape::API sublcass:

require 'grape'
require 'grape-swagger'
require 'grape-cors'

class MyApi < Grape::API
end

class Root < Grape::API
  mount MyApi

  add_swagger_documentation
  allow_cross_domain_request_from "*"
end
