GitHub - michaelwnyc/grape-swagger: Add OAPI/swagger v2.0 compliant documentation to your grape API

What is grape-swagger?

The grape-swagger gem provides an autogenerated documentation for your Grape API. The generated documentation is Swagger-compliant, meaning it can easily be discovered in Swagger UI. You should be able to point the petstore demo to your API.

This screenshot is based on the Hussars sample app.

Compatibility

The following versions of grape, grape-entity and grape-swagger can currently be used together.

grape-swagger	swagger spec	grape	grape-entity	representable
0.10.5	1.2	>= 0.10.0 ... <= 0.14.0	< 0.5.0	n/a
0.11.0	1.2	>= 0.16.2	< 0.5.0	n/a
0.25.2	2.0	>= 0.14.0 ... <= 0.18.0	<= 0.6.0	>= 2.4.1

0.27.0	2.0	>= 0.16.2	=> 0.5.0	>= 2.4.1

Swagger-Spec

Grape-swagger generates documentation per Swagger / OpenAPI Spec 2.0.

Installation

Add to your Gemfile:

gem 'grape-swagger'

Upgrade

Please see UPGRADING when upgrading from a previous version.

Usage

Mount all your different APIs (with Grape::API superclass) on a root node. In the root class definition, include add_swagger_documentation, this sets up the system and registers the documentation on '/swagger_doc'. See example/config.ru for a simple demo.

require 'grape-swagger'

module API
  class Root < Grape::API
    format :json
    mount API::Cats
    mount API::Dogs
    mount API::Pirates
    add_swagger_documentation
  end
end

To explore your API, either download Swagger UI and set it up yourself or go to the online swagger demo and enter your localhost url documentation root in the url field (probably something in the line of http://localhost:3000/swagger_doc).

Model Parsers

Since 0.21.0, Grape::Entity is not a part of grape-swagger, you need to add grape-swagger-entity manually to your Gemfile. Also added support for representable via grape-swagger-representable.

# For Grape::Entity ( https://github.com/ruby-grape/grape-entity )
gem 'grape-swagger-entity'
# For representable ( https://github.com/apotonick/representable )
gem 'grape-swagger-representable'

If you are not using Rails, make sure to load the parser inside your application initialization logic, e.g., via require 'grape-swagger/entity' or require 'grape-swagger/representable'.

Custom Model Parsers

You can create your own model parser, for example for roar.

module GrapeSwagger
  module Roar
    class Parser
      attr_reader :model
      attr_reader :endpoint

      def initialize(model, endpoint)
        @model = model
        @endpoint = endpoint
      end

      def call
        # Parse your model and return hash with model schema for swagger
      end
    end
  end
end

Then you should register your custom parser.

GrapeSwagger.model_parsers.register(GrapeSwagger::Roar::Parser, Roar::Decorator)

To control model parsers sequence, you can insert your parser before or after another parser.

insert_before

GrapeSwagger.model_parsers.insert_before(GrapeSwagger::Representable::Parser, GrapeSwagger::Roar::Parser, Roar::Decorator)

insert_after

GrapeSwagger.model_parsers.insert_after(GrapeSwagger::Roar::Parser, GrapeSwagger::Representable::Parser, Representable::Decorator)

As we know, Roar::Decorator uses Representable::Decorator as a superclass, this allows to avoid a problem when Roar objects are processed by GrapeSwagger::Representable::Parser instead of GrapeSwagger::Roar::Parser.

CORS

If you use the online demo, make sure your API supports foreign requests by enabling CORS in Grape, otherwise you'll see the API description, but requests on the API won't return. Use rack-cors to enable CORS.

require 'rack/cors'
use Rack::Cors do
  allow do
    origins '*'
    resource '*', headers: :any, methods: [ :get, :post, :put, :delete, :options ]
  end
end

Alternatively you can set CORS headers in a Grape before block.

before do
  header['Access-Control-Allow-Origin'] = '*'
  header['Access-Control-Request-Method'] = '*'
end

You can pass a hash with optional configuration settings to add_swagger_documentation. The examples show the default value.

The host and base_path options also accept a proc or a lambda to evaluate, which is passed a request object:

add_swagger_documentation \
  base_path: proc { |request| request.host =~ /^example/ ? '/api-example' : '/api' }

host:

Sets explicit the host, default would be taken from request.

add_swagger_documentation \
   host: 'www.example.com'

base_path:

Base path of the API that's being exposed, default would be taken from request.

add_swagger_documentation \
   base_path: nil

host and base_path are also accepting a proc or lambda

mount_path:

The path where the API documentation is loaded, default is: /swagger_doc.

add_swagger_documentation \
   mount_path: '/swagger_doc'

add_base_path:

Add basePath key to the documented path keys, default is: false.

add_swagger_documentation \
   add_base_path: true # only if base_path given

add_version:

Add version key to the documented path keys, default is: true, here the version is the API version, specified by grape in path

add_swagger_documentation \
   add_version: true

doc_version:

Specify the version of the documentation at info section, default is: '0.0.1'

add_swagger_documentation \
   doc_version: '0.0.1'

endpoint_auth_wrapper:

Specify the middleware to use for securing endpoints.

add_swagger_documentation \
   endpoint_auth_wrapper: WineBouncer::OAuth2

swagger_endpoint_guard:

Specify the method and auth scopes, used by the middleware for securing endpoints.

add_swagger_documentation \
   swagger_endpoint_guard: 'oauth2 false'

token_owner:

Specify the token_owner method, provided by the middleware, which is typically named 'resource_owner'.

add_swagger_documentation \
   token_owner: 'resource_owner'

security_definitions:

Specify the Security Definitions Object

NOTE: Swagger-UI is supporting only implicit flow yet

add_swagger_documentation \
  security_definitions: {
    api_key: {
      type: "apiKey",
      name: "api_key",
      in: "header"
    }
  }

security:

Specify the Security Object

add_swagger_documentation \
  security: [
    {
      api_key: []
    }
  ]

models:

A list of entities to document. Combine with the grape-entity gem.

These would be added to the definitions section of the swagger file.

add_swagger_documentation \
   models: [
     TheApi::Entities::UseResponse,
     TheApi::Entities::ApiError
   ]

tags:

A list of tags to document. By default tags are automatically generated for endpoints based on route names.

add_swagger_documentation \
  tags: [
    { name: 'widgets', description: 'A description of widgets' }
  ]

hide_documentation_path: (default: `true`)

add_swagger_documentation \
   hide_documentation_path: true

Don't show the /swagger_doc path in the generated swagger documentation.

info:

add_swagger_documentation \
  info: {
    title: "The API title to be displayed on the API homepage.",
    description: "A description of the API.",
    contact_name: "Contact name",
    contact_email: "[email protected]",
    contact_url: "Contact URL",
    license: "The name of the license.",
    license_url: "www.The-URL-of-the-license.org",
    terms_of_service_url: "www.The-URL-of-the-terms-and-service.com",
  }

A hash merged into the info key of the JSON documentation.

Swagger Header Parameters

Swagger also supports the documentation of parameters passed in the header. Since grape's ```params[]``` doesn't return header parameters we can specify header parameters seperately in a block after the description.

desc "Return super-secret information", {
  headers: {
    "XAuthToken" => {
      description: "Valdates your identity",
      required: true
    },
    "XOptionalHeader" => {
      description: "Not really needed",
      required: false
    }
  }
}

Hiding an Endpoint

You can hide an endpoint by adding hidden: true in the description of the endpoint:

desc 'Hide this endpoint', hidden: true

Or by adding hidden: true on the verb method of the endpoint, such as get, post and put:

get '/kittens', hidden: true do

Or by using a route setting:

route_setting :swagger, { hidden: true }
get '/kittens' do

Endpoints can be conditionally hidden by providing a callable object such as a lambda which evaluates to the desired state:

desc 'Conditionally hide this endpoint', hidden: lambda { ENV['EXPERIMENTAL'] != 'true' }

Overriding Auto-Generated Nicknames

You can specify a swagger nickname to use instead of the auto generated name by adding `:nickname 'string'``` in the description of the endpoint.

desc 'Get a full list of pets', nickname: 'getAllPets'

Specify endpoint details

To specify further details for an endpoint, use the detail option within a block passed to desc:

desc 'Get all kittens!' do
  detail 'this will expose all the kittens'
end
get '/kittens' do

Overriding the route summary

To override the summary, add summary: '[string]' after the description.

namespace 'order' do
  desc 'This will be your summary',
    summary: 'Now this is your summary!'
  get :order_id do
    ...
  end
end

Overriding the tags

Tags are used for logical grouping of operations by resources or any other qualifier. To override the tags array, add tags: ['tag1', 'tag2'] after the description.

namespace 'order' do
  desc 'This will be your summary', tags: ['orders']
  get :order_id do
    ...
  end
end

Deprecating routes

To deprecate a route add deprecated: true after the description.

namespace 'order' do
  desc 'This is a deprecated route', deprecated: true
  get :order_id do
    ...
  end
end

Overriding the name of the body parameter

By default, body parameters have a generated name based on the operation. For deeply nested resources, this name can get very long. To override the name of body parameter add body_name: 'post_body' after the description.

namespace 'order' do
  desc 'Create an order', body_name: 'post_body'
  post do
    ...
  end
end

Defining an endpoint as an array

You can define an endpoint as an array by adding is_array in the description:

desc 'Get a full list of pets', is_array: true

Using an options hash

The Grape DSL supports either an options hash or a restricted block to pass settings. Passing the nickname, hidden and is_array options together with response codes is only possible when passing an options hash. Since the syntax differs you'll need to adjust it accordingly:

desc 'Get all kittens!', {
  hidden: true,
  is_array: true,
  nickname: 'getKittens',
  success: Entities::Kitten, # or success
  failure: [[401, 'KittenBitesError', Entities::BadKitten]] # or failure
  # also explicit as hash: [{ code: 401, message: 'KittenBitesError', model: Entities::BadKitten }]
  produces: [ "array", "of", "mime_types" ],
  consumes: [ "array", "of", "mime_types" ]
  }
get '/kittens' do

Overriding parameter type

You can override paramType, using the documentation hash. See parameter object for available types.

params do
  requires :action, type: Symbol, values: [:PAUSE, :RESUME, :STOP], documentation: { param_type: 'query' }
end
post :act do
  ...
end

Overriding data type of the parameter

You can override type, using the documentation hash.

params do
  requires :input, type: String, documentation: { type: 'integer' }
end
post :act do
  ...
end

{
  "in": "formData",
  "name": "input",
  "type": "integer",
  "format": "int32",
  "required": true
}

Multiple types

By default when you set multiple types, the first type is selected as swagger type

params do
  requires :action, types: [String, Integer]
end
post :act do
  ...
end

{
  "in": "formData",
  "name": "action",
  "type": "string",
  "required": true
}

Array of data type

Array types are also supported.

params do
  requires :action_ids, type: Array[Integer]
end
post :act do
  ...
end

{
  "in": "formData",
  "name": "action_ids",
  "type": "array",
  "items": {
      "type": "integer"
  },
  "required": true
}

Collection format of arrays

You can set the collection format of an array, using the documentation hash.

Collection format determines the format of the array if type array is used. Possible values are:

csv - comma separated values foo,bar.
ssv - space separated values foo bar.
tsv - tab separated values foo\tbar.
pipes - pipe separated values foo|bar.
multi - corresponds to multiple parameter instances instead of multiple values for a single instance foo=bar&foo=baz. This is valid only for parameters in "query" or "formData".

params do
  requires :statuses, type: Array[String], documentation: { collectionFormat: 'multi' }
end
post :act do
  ...
end

{
  "in": "formData",
  "name": "statuses",
  "type": "array",
  "items": {
      "type": "string"
  },
  "collectionFormat": "multi",
  "required": true
}

Hiding parameters

Exclude single optional parameter from the documentation

params do
  optional :one, documentation: { hidden: true }
  optional :two, documentation: { hidden: -> { true } }
end
post :act do
  ...
end

Setting a Swagger default value

Grape allows for an additional documentation hash to be passed to a parameter.

params do
  requires :id, type: Integer, desc: 'Coffee ID'
  requires :temperature, type: Integer, desc: 'Temperature of the coffee in celcius', documentation: { default: 72 }
end

The example parameter will populate the Swagger UI with the example value, and can be used for optional or required parameters.

Grape uses the option default to set a default value for optional parameters. This is different in that Grape will set your parameter to the provided default if the parameter is omitted, whereas the example value above will only set the value in the UI itself. This will set the Swagger defaultValue to the provided value. Note that the example value will override the Grape default value.

params do
  requires :id, type: Integer, desc: 'Coffee ID'
  optional :temperature, type: Integer, desc: 'Temperature of the coffee in celcius', default: 72
end

Expose nested namespace as standalone route

Use the nested: false property in the swagger option to make nested namespaces appear as standalone resources. This option can help to structure and keep the swagger schema simple.

namespace 'store/order', desc: 'Order operations within a store', swagger: { nested: false } do
  get :order_id do
  	...
  end
end

All routes that belong to this namespace (here: the GET /order_id) will then be assigned to the store_order route instead of the store resource route.

It is also possible to expose a namespace within another already exposed namespace:

namespace 'store/order', desc: 'Order operations within a store', swagger: { nested: false } do
  get :order_id do
  	...
  end
  namespace 'actions', desc: 'Order actions' do, nested: false
    get 'evaluate' do
      ...
    end
  end
end

Here, the GET /order_id appears as operation of the store_order resource and the GET /evaluate as operation of the store_orders_actions route.

With a custom name

Auto generated names for the standalone version of complex nested resource do not have a nice look. You can set a custom name with the name property inside the swagger option, but only if the namespace gets exposed as standalone route. The name should not contain whitespaces or any other special characters due to further issues within swagger-ui.

namespace 'store/order', desc: 'Order operations within a store', swagger: { nested: false, name: 'Store-orders' } do
  get :order_id do
  	...
  end
end

Response documentation

You can also document the HTTP status codes with a description and a specified model, as ref in the schema to the definitions, that your API returns with one of the following syntax.

In the following cases, the schema ref would be taken from route.

desc 'thing', failure: [ { code: 400, message: 'Invalid parameter entry' } ]
get '/thing' do
  ...
end

desc 'thing' do
  params Entities::Something.documentation
  failure [ { code: 400, message: 'Invalid parameter entry' } ]
end
get '/thing' do
  ...
end

get '/thing', failure: [
  { code: 400, message: 'Invalid parameter entry' },
  { code: 404, message: 'Not authorized' },
] do
  ...
end

By adding a model key, e.g. this would be taken.

get '/thing', failure: [
  { code: 400, message: 'General error' },
  { code: 422, message: 'Invalid parameter entry', model: Entities::ApiError }
] do
  ...
end

If no status code is defined defaults would be taken.

The result is then something like following:

"responses": {
  "200": {
    "description": "get Horses",
    "schema": {
      "$ref": "#/definitions/Thing"
    }
  },
  "401": {
    "description": "HorsesOutError",
    "schema": {
      "$ref": "#/definitions/ApiError"
    }
  }
},

Changing default status codes

The default status codes, one could be found (-> status codes) can be changed to your specific needs, to achive it, you have to change it for grape itself and for the documentation.

desc 'Get a list of stuff',
    success: { code: 202, model: Entities::UseResponse, message: 'a changed status code' }
get do
  status 202
  # your code comes here
end
…

"responses": {
  "202": {
    "description": "ok",
    "schema": {
      "$ref": "#/definitions/UseResponse"
    }
  }
},

File response

Set success to File and sets also produces. If produces wasn't set, it defaults to application/octet-stream.

desc 'Get a file',
    success: File
get do
  # your file reponse
end
…

"produces": [
  "application/octet-stream"
],
"responses": {
  "200": {
    "description": "Get a file",
    "schema": {
      "type": "file"
    }
  }
}

Extensions

Swagger spec2.0 supports extensions on different levels, for the moment, the documentation on the root level object and the info, verb, path and definition levels are supported. The documented key would be generated from the x + - + key of the submitted hash, for possibilities refer to the extensions spec. To get an overview how the extensions would be defined on grape level, see the following examples:

root object extension, add a x key to the root hash when calling add_swagger_documentation:

  add_swagger_documentation \
    x: {
      some: 'stuff'
    },
    info: {
    }

this would generate:

{
  "x-some": "stuff",
  "info":{
  }
}

info extension, add a x key to the info hash when calling add_swagger_documentation:

  add_swagger_documentation \
    info: {
      x: { some: 'stuff' }
    }

this would generate:

"info":{
  "x-some":"stuff"
}

verb extension, add a x key to the desc hash:

desc 'This returns something with extension on verb level',
  x: { some: 'stuff' }

this would generate:

"/path":{
  "get":{
    "…":"…",
    "x-some":"stuff"
  }
}

operation extension, by setting via route settings::

route_setting :x_operation, { some: 'stuff' }

this would generate:

"/path":{
  "get":{
    "…":"…",
    "x-some":"stuff"
  }
}

path extension, by setting via route settings:

route_setting :x_path, { some: 'stuff' }

this would generate:

"/path":{
  "x-some":"stuff",
  "get":{
    "…":"…",
  }
}

definition extension, again by setting via route settings, here the status code must be provided, for which definition the extensions should be:

route_setting :x_def, { for: 422, other: 'stuff' }

this would generate:

"/definitions":{
  "ApiError":{
    "x-other":"stuff",
    "…":"…",
  }
}

or, for more definitions:

route_setting :x_def, [{ for: 422, other: 'stuff' }, { for: 200, some: 'stuff' }]

Using Grape Entities

Add the grape-entity and grape-swagger-entity gem to your Gemfile.

The following example exposes statuses. And exposes statuses documentation adding :type, :desc and :required. The documented class/definition name could be set via #entity_name.

module API
  module Entities
    class Status < Grape::Entity
      expose :text, documentation: { type: 'string', desc: 'Status update text.', required: true }
      expose :links, using: Link, documentation: { type: 'link', is_array: true }
      expose :numbers, documentation: { type: 'integer', desc: 'favourite number', values: [1,2,3,4] }
    end

    class Link < Grape::Entity
      expose :href, documentation: { type: 'url' }
      expose :rel, documentation: { type: 'string'}

      def self.entity_name
        'LinkedStatus'
      end

    end
  end

  class Statuses < Grape::API
    version 'v1'

    desc 'Statuses index',
      entity: API::Entities::Status
    get '/statuses' do
      statuses = Status.all
      type = current_user.admin? ? :full : :default
      present statuses, with: API::Entities::Status, type: type
    end

    desc 'Creates a new status',
      entity: API::Entities::Status,
      params: API::Entities::Status.documentation
    post '/statuses' do
        ...
    end
  end
end

Relationships

You may safely omit type from relationships, as it can be inferred. However, if you need to specify or override it, use the full name of the class leaving out any modules named Entities or Entity.

1xN

module API
  module Entities
    class Client < Grape::Entity
      expose :name, documentation: { type: 'string', desc: 'Name' }
      expose :addresses, using: Entities::Address,
        documentation: { type: 'Entities::Address', desc: 'Addresses.', param_type: 'body', is_array: true }
    end

    class Address < Grape::Entity
      expose :street, documentation: { type: 'string', desc: 'Street.' }
    end
  end

  class Clients < Grape::API
    version 'v1'

    desc 'Clients index',
      params: Entities::Client.documentation,
      success: Entities::Client
    get '/clients' do
      ...
    end
  end

  add_swagger_documentation
end

Note: is_array is false by default.

module API
  module Entities
    class Client < Grape::Entity
      expose :name, documentation: { type: 'string', desc: 'Name' }
      expose :address, using: Entities::Address,
        documentation: { type: 'Entities::Address', desc: 'Addresses.', param_type: 'body', is_array: false }
    end

    class Address < Grape::Entity
      expose :street, documentation: { type: 'string', desc: 'Street' }
    end
  end

  class Clients < Grape::API
    version 'v1'

    desc 'Clients index',
      params: Entities::Client.documentation,
      success: Entities::Client
    get '/clients' do
      ...
    end
  end

  add_swagger_documentation
end

Securing the Swagger UI

The Swagger UI on Grape could be secured from unauthorized access using any middleware, which provides certain methods:

some guard method, which could receive as argument a string or an array of authorization scopes;
a before method to be run in the Grape controller for authorization purpose;
a set of methods which will process the access token received in the HTTP request headers (usually in the 'HTTP_AUTHORIZATION' header) and try to return the owner of the token.

Below are some examples of securing the Swagger UI on Grape installed along with Ruby on Rails:

The WineBouncer and Doorkeeper gems are used in the examples;
'rails' and 'wine_bouncer' gems should be required prior to 'grape-swagger' in boot.rb;
This works with a fresh PR to WineBouncer which is yet unmerged - WineBouncer PR.

This is how to configure the grape_swagger documentation:

  add_swagger_documentation base_path: '/',
                            title: 'My API',
                            doc_version: '0.0.1',
                            hide_documentation_path: true,
                            endpoint_auth_wrapper: WineBouncer::OAuth2, # This is the middleware for securing the Swagger UI
                            swagger_endpoint_guard: 'oauth2 false',     # this is the guard method and scope
                            token_owner: 'resource_owner'               # This is the method returning the owner of the token

The guard method should inject the Security Requirement Object into the endpoint's route settings (see Grape::DSL::Settings.route_setting method).

The 'oauth2 false' added to swagger_documentation is making the main Swagger endpoint protected with OAuth, i.e. the access_token is being retreiving from the HTTP request, but the 'false' scope is for skipping authorization and showing the UI for everyone. If the scope would be set to something else, like 'oauth2 admin', for example, than the UI wouldn't be displayed at all to unauthorized users.

Further on, the guard could be used, where necessary, for endpoint access protection. Put it prior to the endpoint's method:

  resource :users do
    oauth2 'read, write'
    get do
      render_users
    end

    oauth2 'admin'
    post do
      User.create!...
    end
  end

And, finally, if you want to not only restrict the access, but to completely hide the endpoint from unauthorized users, you could pass a lambda to the :hidden key of a endpoint's description:

  not_admins = lambda { |token_owner = nil| token_owner.nil? || !token_owner.admin? }

  resource :users do
    desc 'Create user', hidden: not_admins
    oauth2 'admin'
    post do
      User.create!...
    end
  end

The lambda is checking whether the user is authenticated (if not, the token_owner is nil by default), and has the admin role - only admins can see this endpoint.

Use namespace for grouping APIs

Example Code

class NamespaceApi < Grape::API
  namespace :hudson do
    desc 'Document root'
    get '/' do
    end

    desc 'This gets something.',
      detail: '_test_'

    get '/simple' do
      { bla: 'something' }
    end
  end

  namespace :download do
    desc 'download files',
         success: File,
         produces: ['text/csv']
    get ':id' do
      # file response
    end
  end
end
